8 Air Conditioning Energy Saving Tips

No matter what kind of air conditioning unit you have, the following 8 Air Conditioning Energy Saving Tips can help lower your energy costs as Las Vegas heats up this Spring and Summer. Some of these air conditioning energy savings tips may seem like common sense. Others may come as a surprise. All 8 energy saving tips will help control expensive energy leaks, create more comfort in your home and extend the life of your air conditioning system.

Air Conditioning Energy Saving Tip #1 – Only Cool Spaces You’re Using

Locate air vents and reduce air flow to spaces you do not frequent such as storage rooms, garages and basements. This is common sense, but it takes intentional action. Schedule a day and time when you will evaluate the use of various spaces in your home and reduce air flow to non-living spaces. This will additionally help your air conditioning system more quickly and rapidly cool the spaces you frequent.

Air Conditioning Energy Saving Tip #2 – Leave Your Thermostat Alone!

This may be counterintuitive. Doesn’t it seem logical that setting the air conditioning higher (warmer) during times you are away (during the day) and setting it cooler when you are at home would save energy? Why run the air conditioning when you’re not home? The science says differently. Every time you reset your thermostat your air conditioner has to work harder to get your living space back to a comfortable temperature. It has not only to cool down the air in your home, but also cool down your walls, furniture, rugs…every object in your home! This requires more energy than leaving your thermostat at a steady temperature. As with a car, the most energy is used during acceleration vs. cruising at a steady speed (thus highway MPG is always better than city driving). In addition, changes in temperature result in condensation of moisture which causes your air conditioning system to work even harder.

Air Conditioning Energy Saving Tip #3 – Clear Away Objects Blocking Your Air Vents

If all the cool air your air conditioner is generating pours out of the vent and hits a couch, your couch will absorb a good part of the cool air. In the meantime, your thermostat is registering that the air in your home is warmer and sends a message to your air conditioner to generate more cool air which once again gets absorbed by your couch. Vicious cycle of waste raising your energy bill!

Air Conditioning Energy Saving Tip #4 – Keep Heat Sources Away from Your Thermostat

Imagine a lamp, radio or T.V. near your thermostat generating heat and telling your thermostat to send a message to your air conditioner to work harder. It’s measuring the heat pouring off of the T.V. instead of the air temperature of your home and will work until your T.V. reached the temperature you set for your home. Not going to happen. Energy waste!

Air Conditioning Energy Saving Tip #5 – Set Your Thermostat to a Comfortable Setting, But Not Necessarily an Arctic Setting

I love cooler temperatures. But were I to set my thermostat to a temperature that feels best, we’d be looking at about 65 degrees or even less. Sacrificing a few degrees during the hottest time of the year can create huge savings, while not greatly sacrificing comfort. A good time-proven principle to have in mind is “moderation”.

Air Conditioning Energy Saving Tip #6 – Vent Heat Sources Away from Your Home

Turn on your kitchen exhaust fan while cooking. Don’t let stove and oven heat escape into your home. Periodically check your clothing dryer vent to make sure there is no blockage or disconnected vents. Vents behind your dryer can come loose and you’ll never know because they are hidden. Is the outer vent at the other end of your dryer ducts free of debris and operating properly? Besides trapping heat and sending it into your home making your air conditioner work harder, a lint-blocked dryer vent can be a fire hazard!

Air Conditioning Energy Saving Tip #7 – Check That the Exhaust from Your Air Condenser Is Sent Away from the Condenser

This is probably more a job for the professional who installs or maintains your air condenser. If your air condenser is positioned is such a way that the hot air exhaust can be sucked in by the intake of the condenser or a neighboring condenser (in the case two are side by side) your cooling system has to work harder.

Air Conditioning Energy Saving Tip #8 – Adjust Your Thermostat Before Entertaining Large Groups

Yes, we said the you should not be tweaking your thermostat settings (above). The reason for this was that you keep your home at an even temperature. However, when you entertain a lot of guests, they can generate considerable heat causing the temperature in your home to fluctuate. Remember, the key is to keep your home at an even temperature.


Observing these 8 Air Conditioning Energy Saving Tips can save you a substantial amount in your energy bill:

  1. Only Cool Spaces You’re Using
  2. Leave Your Thermostat Alone!
  3. Clear Away Objects Blocking Your Air Vents
  4. Keep Heat Sources Away from Your Thermostat
  5. Set Your Thermostat to a Comfortable Setting, But Not Necessarily an Arctic Setting
  6. Vent Heat Sources Away from Your Home
  7. Check That the Exhaust from Your Air Condenser Is Sent Away from the Condenser
  8. Adjust Your Thermostat Before Entertaining Large Groups

In addition, an air conditioning system that doesn’t have to work as hard will last longer, creating even more energy savings!

How Much To Replace My Air Conditioning System?

Sudden, Unexpected Air Conditioning System Failure

Here’s the nightmare scenario none of us ever want to experience, but somehow, in the deep recesses of our minds we know the day will come: It’s one of those hot 120-degree Las Vegas Summer days. All is well until your home begins to heat up. You check the thermostat settings. They’re set for a comfortable 78-degree temperature. However, the inside temperature has risen to 90 degrees and is climbing! You check your air conditioning unit. There is no activity. You attempt a reset. Still nothing! The inside temperature continues to rise.

Air Conditioning System Evaluation and Estimate

Now, truly worried and realizing this is a problem you cannot fix yourself; you begin to call around for an air conditioning maintenance professional. Hopefully this didn’t happen on a weekend or holiday. The professional arrives, evaluates the problem and determines your air conditioning system is shot and you need a total replacement. A total air conditioning system replacement can run upwards of $17,000! Most people do not have this in their budget.

A More Economical Air Conditioning System Replacement Choice

Fortunately, here is where you have a more economical choice. You may not need a total air conditioning system replacement. In many cases, only one key component of your air conditioning system is shot and needs replacement: Commonly your air condenser. The air condenser is that rectangular unit resting on a block of cement outside of your house, likely in the side yard. Cooling coils are enclosed in a screen, and there’s a fan on top.

Air Condenser Replacement vs. Air Conditioning System Replacement

An air condenser replacement is much less expensive than a total air conditioning system replacement. The reason an air condenser replacement often grows to an entire air conditioning system replacement is due to compatibility. Modern air condensers are often incompatible with the other components of an older air conditioning system. Unless you can locate a compatible air condenser unit, you’ll need to replace your entire air conditioning system.

Guardian “Dry” 14 Seer Air Conditioner R-407C Condenser

Fortunately, there is a new air condenser model that is designed to be compatible with older air conditioning systems. It’s the Guardian “Dry” 14 Seer Air Conditioner R-407C Condenser. It’s compatibility with older air conditioning systems is a huge cost saving feature. Additional cost-saving features make this air condenser easier and less costly to install including:

  • Quick access to power and control wiring
  • Factory installed filter drier cuts down on time spent brazing and charging the system
  • The more compact size allows the unit to fit into the area your old air condenser was placed, without additional construction
  • The components are designed to resist corrosion and rust, extending the life of the air condenser
  • The coil is protected from damage by stamped steel louvered panels
  • The compressors are protected by a high-pressure relief valve, temperature sensor and high-pressure switch
  • The liquid line filter-drier is factory installed to protect the air compressor from moisture and debris

Air Conditioning System Compatibility, Less Expensive Installation, Durability

Some of these features are a bit geeky in detail, but the point is that this new air condenser unit is designed for quick easy installation, designed to last and most importantly, designed to fit the existing components of your older air conditioning system and therefore, may eliminate the huge cost of a total air conditioning system replacement. Replace ONLY your air condenser.

How to Know When it’s Time to Replace Your Home’s Furnace or Air Conditioner?

Furnaces and Air Conditioners are Designed for Comfort, But for How Long?

Your home furnace and air conditioner are designed to keep you comfortable during the hottest Las Vegas Summer days and the coolest Las Vegas Winter nights. However, for most people their furnace and air conditioner are hidden in a place (garage or attic) “out of sight, out of mind” and therefore easy to forget. We assume they will continue working because they have worked for months or even years without much attention. How can you know when it’s time to replace your home’s furnace or air conditioner?

1) The Crisis Method of Predicting the Life of Your Furnace or Air Conditioner

Wait until your furnace or air conditioner breaks down.

Here’s the scenario you might expect: Your house is suddenly freezing some Winter night or boiling some Summer day.

DIY Attempts to Fix the Issue

First, you play around with the thermostat settings. Nothing! Then you locate your furnace or air conditioner. Dig through storage to locate a ladder to get into the crawl space in your closet ceiling. Then clear a space for the ladder. Hopefully you can find a flashlight to light your way once you emerge into your attic. Remember, you’re either boiling hot or so cold you can hardly work your hands. You finally manage to locate the furnace or air conditioner, digging through items stacked up in the way. If you’re lucky, you locate the settings and trip a switch thinking it just needs a restart. Nothing!

Calling In a Professional for Emergency Service

Okay, now you know you need to call in a professional. However, it’s likely a Friday evening right before a holiday weekend! Emergency service may not be coming tonight! You make a run to the department store to invest in a space heater or portable air conditioning unit or a huge fan to tide you over until professional service arrives. When the professional does arrive, they may not be able to fix your air conditioner or furnace on the spot but have to order parts. Another few days of waiting in freezing or boiling hot indoor temperatures! In an extreme situation you may even need to move to a motel or a friend or relative’s house for a few days. Imagine what your family members are thinking of you at this moment! So much for the crisis method of how to know when it’s time to replace your home’s furnace or air conditioner.

2) The Guesswork Method of Predicting When Your Furnace or Air Conditioner’s Life May End:

Try to Guess the Life of Your Furnace or Air Conditioner

This is better than the crisis method. You may avert an emergency breakdown of your home’s air conditioner or furnace with the guesswork method. It goes something like this: You reason that most warranties cover 10 years. Why? Because the smart warranty people figure that your air conditioner or furnace will work relatively problem free for about 10 years before things begin to break down.

Schedule Professional Maintenance Near the End of the 10-Year Warranty Period

You call a professional in for a thorough maintenance visit between year’s 9 and 10. If you’re lucky your air conditioner or furnace did not break down earlier. The professional performs maintenance that extends the life of your air conditioner or furnace a few more years. In addition, they might be able to predict how many years your air conditioner or furnace have left before they need to be replaced. You beat the odds and avoided an emergency breakdown, perhaps extending the life of your air conditioner or furnace a few years.

3) The Proactive Method of Knowing When Your Furnace or Air Conditioner Might Break Down

Schedule regular maintenance.

You have a professional perform regular maintenance at least annually thereby extending the life of your home’s air conditioner or furnace, potentially up to 10 additional years giving you 20 years in all. At the same time, your professional may be able to more accurately predict within a few months to a year when it’s time to give in and replace your furnace or air conditioner.

Now Is the Time to Replace Your Old Home Furnace or Air Conditioner

Is your home’s furnace or air conditioner nearing the age of 10? Now is the time to have Mastermind Mechanical do a health check and either give your furnace or air conditioner additional years of life or get you into a brand-new furnace or air conditioner while this limited special is running! Schedule a Maintenance Check

How to Clean Your Home’s Air Conditioner

Quick 30-Minute Air Condenser Cleaning Tutorial

This quick 2-part process can save you energy expense and extend the life of your home’s air conditioner. It will only take you about 30 minutes and you don’t need to have any special experience or training. If you can work a screwdriver and a garden hose you’re good to go!

Locating Your Air Condenser

We’re going to focus on your home’s air condenser. This is the small unit outside your home, usually in the side yard on a foundation block of cement. It looks like this:


Familiar? Now let’s take a closer look. The part you’re going to clean is the fins. Like the radiator in your car, their important function is to dissipate heat. This is how your air conditioning system cools the air in your home. The air condenser fins are pictured here:

Air Condenser Fins las-vegas-mastermind-mechanical

In order to dissipate heat efficiently, your air condenser fins need to be clean and in good condition. The fins of your air condenser unit accumulate dust and debris during those windy Las Vegas desert days. As the debris build up, your air condenser has to work harder to keep your home cool. You may end up running your air conditioner more often or turning the temperature down further in order to cool your home. This is going to cost you. Your home will actually be hotter in spite of your air conditioner working harder and expending more energy!

On the other hand, clean the fins of your air condenser unit 2-3 times each year: In the early Spring, mid-Summer and in the Fall to save on energy expense and be more comfortable in your home during our hot Las Vegas Summers.

Take a close look at the air condenser fins in the picture above. Note the debris accumulated in the fins. This routinely occurs. Also, note that some of the fins are bent and deformed. This also happens over time. We’ll refer back to this picture.

Here are 8 steps to cleaning your air condenser fins:

1) Turn off the Power to Your Air Condenser

The power switch is located on a wall connected to your air condenser. It looks like this:


You can easily remove the power switch cover and turn it to the off position.

2) Remove the Top of Your Air Condenser Unit

The top is a metal grillwork located just above the large air condenser fan. Note there are a number of screws or bolts. A screwdriver will often do the trick. You may need a socket wrench depending on the type of bolt. The top of the air condenser is pictured here:



You’ll need a screwdriver or socket wrench depending on the type of bolts attaching the top to the base of the air condenser. As you remove the top, watch carefully to ensure you are not disturbing any wires within the unit. You’ll also want to lift the fan so you can get to the air condenser fins below. As you remove the top, remember how everything looked before you touched it. You’ll need to replace it again later.

Consider all those little bolts. Please have an empty jar or can with you to store the bolts until you replace them later! Seriously…look at the landscaping rocks surrounding the unit. Imagine those tiny bolts falling into the rocks! You’ll never find them again. You’ll end up going to a hardware store to find replacements…searching for the exact same size…it can be a nightmare.

Once you remove the top, carefully remove all debris from inside the unit. There may well be leaves and twigs and bugs. Lots of stuff collects there over time. Get it all out!

3) Hose Off the Air Condenser Fins from the Inside Out

A regular garden hose will do the trick. Use a light spray. Do not use a power washer as this could damage the unit. Carefully hose off every area of the air condenser fins all the way around the air condenser. Be sure to direct the water from inside to outside the unit. Do not spray the outside as this will cause any dust and debris to lodge further into the unit.

4) Brush the Air Condenser Fins with a Fin Brush

Pictured here are a fin brush and a fin comb. You can find them at most hardware stores. We easily located the fin brush and comb pictured below on Amazon for under $8 by searching “air condenser comb”. The fin brush is on the left, the comb on the right. Note that there are air cooling fins behind your refrigerator, under the hood of your car and just about anywhere there is an air cooling system. These tools will work on most air cooling fins anywhere.


The fin brush removes debris from the air condenser fins. It’s a good idea to use the fin brush on all air condenser fins regardless of their age or condition. Carefully brush the outside of the fins all around your air condenser.

5) Straighten Any Bent Condenser Fins with a Fin Comb

The fin comb straightens any bent fins and helps provide the separation necessary to let the fins dissipate heat properly. In the case of severely bent or damaged fins, you can gently insert a kitchen knife between the fins to straighten them. Do not insert the knife more than 1/4th inch into the fins, and stay away from the coils in order to avoid damaging, or heaven forbid, puncturing them!

If you look closely at the air condenser fins in the picture above you can see some bent fins. The air condenser fin comb is designed to gently insert between the fins and straighten them out without damaging them.

6) Spray the Fins with a Fin and Coil Cleaner

Here is an example of a fin and coil cleaner we easily found on Amazon. We’re not attempting to sell any particular brand of any of these products and picture them only to help give you an idea what you’re looking for. Feel free to shop around. There are numerous brands available:


As with the air condenser brush and comb, the coil cleaner is especially designed to clean the fins and coils of any cooling system whether it’s your refrigerator, car or other. It dissolves dirt, dust and debris without damaging the fins. Go nuts and clean them all, making all your cooling systems function more efficiently at a lower cost. For example, when is the last time you pulled your refrigerator away from the wall and looked behind it? Scary!! This is a good example of what collects where ever there are air cooling fins and coils where air is continually passing through along with scads of dust particles and other unmentionable stuff!

7) Replace the Top of Your Air Condenser Unit

Be careful to replace the top of your air condenser unit exactly as it was before you removed it. This is the time you especially appreciate having stored all the screws and bolts in a jar at the beginning of this little adventure.

8) Turn the Power Back On

Take a moment to congratulate yourself! That wasn’t so hard was it? You just helped your air condenser to run more efficiently saving you money month after month and making your home more comfortable. And if you were extra ambitious, perhaps you did the same for your refrigerator!

Replace Air Filters

Another easy task we refer to as low effort, high results is to change your air filters monthly. See this article on our site.

Additional Care and Maintenance of Your Air Conditioning System

Your home’s air conditioning system also contains coils that need cleaning and parts that need special lubrication delivered at the exact right spot. And in addition to the air condenser unit outside your home, there is a larger evaporator unit inside your home – likely in the attic – that has parts important to maintain. Some parts need lubrication. Hoses need to be taken apart and cleaned. Parts may wear out over time. Watch for additional blog articles on maintaining these.

We didn’t want to overwhelm you, so we stuck to the air condenser fins in this article. Cleaning these is the lowest effort task with the highest results. If you keep your air condenser fins clean 2-3 times annually, the other components of your air conditioning system will not have to work as hard and will last longer.

Have Your Home Air Conditioning and Heating System Professionally Inspected and Tuned-Up Annually

We suggest you contact us to professionally service your home’s air conditioning system annually. If this is an off season, you’re in luck. That’s the best time to call for maintenance. During high demand seasons, professionals get booked up, parts can be harder to obtain and some may even raise their prices – we don’t. Though, scheduling can be tricky during those high-demand seasons (i.e. the outside temperature is 120 degrees, your poorly maintained air condenser breaks down on…you guessed it…a Friday evening. You spend the weekend trying to find a HVAC maintenance person rather than escaping to cooler climates on a much needed vacation).

Don’t let yourself get into that bad bad situation. Call us now to schedule your annual HVAC system maintenance. We’ll take care of everything for you…fins and all!

Tips on Choosing a Thermostat

Any homeowner wants the HVAC system to work as efficiently as possible, which includes choosing a thermostat. A well-functioning HVAC system will make your home as comfortable as possible without running up your monthly energy costs.

Tips on Choosing a Thermostat

There are several ways you can ensure that your heating and cooling system is doing its job. Have you considered purchasing a smart thermometer? Homes are getting smarter, and thermostats are no exception to this. Smart thermostats have several benefits compared to their ancestors. If you are in the market for one, use these tips.


If you don’t have a lot of experience, choose a thermostat that is easy to install. Many options you can install yourself. Install your smart thermostat in an area away from vents and direct sunlight so it can get a correct reading on the temperature in your home. If you aren’t sure what to do, a professional can install it for you.


Each thermostat comes with a variety of features in different combinations. Before you start shopping, consider what is most important to you. For example, a business owner of an office that is closed at night should consider a model with an automatic timer. They can save you a lot of money by automatically turning off your HVAC system when you don’t need it.

Remote Access

Another great feature found on many smart thermostats is remote access. This feature empowers you to control your HVAC system remotely from your smart home. Did it suddenly get a lot hotter while you were at work? Now, you can turn on the HVAC system while you are on the way home, so it’s comfortable when you arrive.


It may seem simple, but a lot of people overlook choosing the thermostat compatible with their HVAC system. In some cases, a smart thermometer may not work with older HVAC systems and certain newer models.

Tips for Choosing the Right Commercial HVAC Contractor

It’s important to hire a trusted HVAC contractor to repair and maintain your commercial HVAC system. The good news is finding a reliable contractor doesn’t have to be difficult. Try these five tips to help you choose the right commercial HVAC contractor for your property in Las Vegas.

Commercial HVAC Contractor Las Vegas

1. Get Referrals

Contact other business owners and property managers for referrals. Ask specific questions about their level of satisfaction with the services. Did the technicians arrive on time? How long did it take them to complete the service? Were the technicians professional? Was the cost of the service more than the estimate?

2. Review HVAC Company Websites

Go to each company’s website and review it to learn more about the business. A good HVAC website includes a list of services, scheduling information, and current specials.

3. Read Customer Reviews

Search engines and third-party providers give customers the opportunity to review companies. Look for reviews of each HVAC company on the internet. Read the good and bad reviews. Reviews can tell you everything you need to know about customer service.

4. Contact Prospective Companies

Make a list of companies, and then call each one to determine if it can meet your needs. Ask questions about estimates, services, and policies. During the phone consultation, find out if the company has the equipment to install, repair, or maintain your HVAC system.

5. Verify Licensing and Insurance

All commercial HVAC companies should be licensed, insured, and bonded. These requirements protect you if something goes wrong. When you contact a company, find out if it meets the basic insurance and bonding requirements in your area. Be sure to also ask for proof to verify that the company is actually licensed, insured, and bonded.

How to Know When It’s Time for AC Repair

Know When It’s Time for AC Repair

Generally known for its extreme summers, Las Vegas can get even hotter than usual during peak summer. From humidity to dry spells, the harsh weather can have detrimental effects on your health, which is why staying indoors, hydrated, and under proper cooling is important.

An AC unit can make things much better, but a number of its components can suffer partial or full damage—both indoors and outdoors. Let’s talk about them before we take a look at the warning signs that allude to them:

  • A broken or clogged condenser
  • Breakage or splits in the AC belt
  • A faulty thermostat
  • Frozen indoor coils
  • A congested air filter

Symptoms of AC Malfunctions

If you’re not sure about how to identify potential problems, let us help you figure out the telltale signs of a faulty unit.

Significant reductions in airflow

If you notice the blower/fan slowing down or feel like the unit isn’t cooling, there’s a high chance that the air filter needs to be tended to. A complete loss of air flow is caused when:

  • There’s no power
  • The thermostat has stopped working
  • A blower door is open
  • The ductwork is disconnected

Warm airflow from the vents

One of the main factors that causes warm airflow is a refrigerant leak. Other reasons may include ducts exposed to excessive heat or missing insulation. These problems will result in increased temperatures in the room.

Significant humidity in the room

Since an AC works best in a confined space, it is essential that you close all windows, doors and any gaps that may let the cool air out and hot air in. Humidity is often experienced as a result of not observing the above-mentioned caution.

Insufficient dehumidification can also be due to the size vs. space ratio, since an oversized AC in a small space will quickly cool the room and reach the cut-off point without fully removing the moisture.

Loud or hissing noises

A failing air compressor will make unusual noises if it suffers a leak or its bearings seize instead of turning.

Often, irregularities in equipment cause irregular cooling and since AC units have a complex internal structure, it’s best to call a professional repair service. Our HVAC and AC repair services ensure that Las Vegas residents are enjoying hot summers without any problems.

If you’re planning on installing a new unit, we also provide expert technicians that can do complete installation, retrofits and upgrades. Give us a quick call at (702) 840-4810 or book an appointment online!

The Importance of Having an HVAC Maintenance Plan

Importance of an HVAC Maintenance Plan

We service HVAC Cooling and Heating Systems in Las Vegas as well as providing emergency repairs, maintenance, and new installation.

The importance of having an HVAC maintenance plan cannot be stressed more. In the long run, it can potentially save you hundreds and even thousands of dollars in costly repairs. Aside from the monetary benefits, there’s a myriad of benefits that regular maintenance can offer.

Our team of Las Vegas HVAC installation, repair, and maintenance experts are ready to do the job right the first time

Here are a few reasons why it’s so important to have an HVAC maintenance plan:

Increase the lifespan of your HVAC unit

Having an effective HVAC maintenance plan in place improves the longevity of your unit. As your HVAC unit will not have to overwork or overcompensate for components that are faulty or subject to extensive wear and tear, they’ll last much longer and work efficiently.

Improved air quality

HVAC unit can help in creating a comfortable indoor environment and save you from harsh weather conditions

However, when dirt and grime is accumulated in the blower parts or coils of the unit, it can give rise to health-related concerns. Regular maintenance can improve air quality and make a healthier atmosphere for you and your family.

Increase the levels of energy efficiency

Regular upkeep of your HVAC system can significantly substantially improve the energy efficiency levels of your HVAC unit. In fact, simply replacement of a clogged, dirty filter can improve your air conditioners energy consumption by 5% to 15%.

Reduce the chances of emergency breakdowns

Most emergency cooling or heating repairs arise due to ignored maintenance. Preventative maintenance can lessen the chances of emergency breakdowns which can be super inconvenient.

Keep your warranty intact

At some point, your HVAC unit will suffer a breakdown and having a warranty intact can save you hundreds of dollars in repairs. There’s a chance that if you don’t maintain your HVAC system, your warranty will be void and you’ll be left with hefty repair bills. Thus, it’s important to maintain your unit to protect your investment.

If you’re looking for an air conditioning service provider for the regular maintenance of your HVAC system, contact Mastermind Mechanical LLC. We’re a family-owned Las Vegas HVAC company that offers top quality repair and maintenance services to our clients.
