How Does An Air Conditioner Work?

Back to Basics

Do you know “How Air Conditioners Work?”

When I started working with Controlled Release about 6 years ago, I didn’t have the slightest clue how an Air Conditioner worked. Obviously, that information is vital in the HVAC Industry.

The President of our company, Lynn Burkhart, states all the time that if you don’t know “how or why” something is the way that it is, you aren’t going to understand it at all.

The majority of you may already know how an Air Conditioner works but the truth is there are those few who don’t know how it works (like me 6 years ago).

For those of you who do know, please chime in with comments and links to sites that you feel are super helpful for those of us who are still in the process of understanding the basics. 

If you are one that doesn’t know how an air conditioner works, check out this simple, yet awesome, 2 minute video below created by Genteq Motors that explains “How an Air Conditioner Works”.

“Perks” of Maintaining Your Air Conditioner

Maintaining your air conditioner is not a good idea, it’s a excellent idea. 

Isn’t is just the most thrilling thing when it’s 100 degrees outside and your Air Conditioner decides to call in sick that day? Leaving you to handle whatever issue is going on and having to call in your local HVAC Contractor. Take a look at the young man below, it’s summer time and he needs not be worried about being cool in the summer. But, for some reason, he is….


How about when it’s winter time. Do you want to be cold & shivering under twenty blankets? Or would you rather be cuddled up on the couch, drinking some hot chocolate, and enjoying family time? Seems like an easy answer, Right? The gentleman in the green jimmies below, is clearly having some HVAC issues and not able to enjoy anything mentioned.


Other than being cool in the summer and warm in the winter, there are a MANY MORE PERKS to maintaining your HVAC system.

Over a years time, dirt builds up on the coil. While the filter helps to slow down the soiling process, the dirt will still find it’s way to your coils. Dirt on coils decreases your airflow, and insulates the coil. As far as the outside coils, they too, become very dirty. Mowing the grass, leaves falling from trees, and wind blowing dust….these all contribute to the dirt build up on the coils.

When regular PM’s are done, you will achieve the following:

  • Preventing costly breakdowns
  • Reducing energy costs
  • Extending the life of the equipment
  • Improving system performance
  • Making the system safer

One of the ways to accomplish these goals are to clean and coat your HVAC system with products that will not eat away at your coils, nor inhibit heat transfer.

Say hello to a Coil Cleaning Kit. It has everything you need to solve any build up problems on your coils. Better yet, it will last a full year. It comes with our Instant Powder Kegs coil cleaner and First Strike Micro Coat easy to use annual coating.

Instant Powder Kegs is a powdered coil cleaner, that is easy to use, clean up and transport. Just mix with water, spray on and rinse.The coil cleaner is removing the dirt and build up on the coils. Then, apply the First Strike Micro Coat which is an annual coating that will repel anything from sticking to your coil. Leaving you with a years worth of protection on your coil.

This Crazy Pancrete Installation is Great for Business

The uses of our product, Pancrete, can vary in so many ways! Typically, Pancrete is a product used to resurface rusty, leaking HVAC drain pans. But one client turned his store’s countertop into a Pancrete display!

Bobby Mantle with Strategic Filtration in Houston, TX, used Pancrete to create a beautiful countertop in his store. He said he decided to use it because it was so beautiful, and it was an easy way to show his clients what Pancrete looks like when installed.

Bobby said it was a very easy process. First, he built the counter out of wood and added a lip to the sides, just enough to pour the Pancrete into. He poured it 1/4″ thick and then caulked the edges to ensure the Pancrete didn’t leak out. It bonded seamlessly to the wood.

His clients love the way it looks and feels, especially with that beautiful blue color. They see it every time they visit his location.

What a cool idea! Have you ever installed a product in an unusual way? Tell us your product stories!

A/C Coil Cleaning – an Art or a Science?

As a busy service technician, what’s often the last thing on your to-do list? For some, it’s cleaning the coils on HVAC units.

Why? It’s messy work, can take up your time, and often feels unnecessary. For those reasons, coil cleaning isn’t usually the first thing that comes up in HVAC conversations.

Over the years, we’ve seen several magazine articles on how to clean coils. More than a dozen contractors have done full-scale tests on coil cleaning. Some have even pulled the entire coil out of the unit and immersed it in cleaning solutions. It’s easy to say that coil cleaning is simple and of little consequence. But nothing could be farther from the truth.

In next month’s newsletter and here on the blog, we’ll share with you the best and easiest ways to clean coils, the benefits for you and for the owner, and all kinds of other important factors.

Do you have questions about coil cleaning? How do you clean coils?

What Size HVAC Do I Need? Part 2: Larger vs. Smaller

This is part two of a three-part series on finding the right size HVAC system for your needs. Read part one here

In part one of our series, we talked about six factors to consider when choosing the right size HVAC for your home. Today, we’ll compare large and small systems and show you the benefits of both.

Larger is Not Always Better

A common misconception is that a larger HVAC system is always better. In fact, the larger the system, the more money you’ll spend on heating and cooling. There are a few reasons people tend to lean towards the “larger is better” mentality. First, their previous HVAC installer said so. Unfortunately, many installers will give you false information specifically to get you to buy the larger system. Your system should be just enough to cool and heat your home, not overdo it. The real reason many installers will give you a larger system is that it will require more maintenance and repairs down the road, leading to more money for their company. It’s a shady, but a common practice.

Larger Systems Require More Energy

As your system starts up, it will pull the most amperage (current) from your home as indicated by the LRA (Locked Rotor Amperage) on the sticker/manufacturer tag on the system. Afterwards, the system will use a continuous flow of significantly less (sometimes up to 75% less) amperage. For example, a system could start up and use 145A for a brief period of time, until the system gets going, then drop down to about 30A continuously. Now imagine the energy usage and strain on your system when it cools the house in a matter of minutes, just to find that it needs to kick on again in about 45 minutes because of the heat/cold outside or poor insulation. Now it has to start up again and pull that 145A current.

Smaller Systems – The Risks and Benefits

A smaller system can take a bit longer to heat or cool your home, but the installer should know if the system has the capabilities to properly regulate your home’s temperature. One problem many find with the smaller systems is that they can be loud when working at their highest capacity, so let your installer know if you prefer a quieter system. Some of the benefits of smaller systems include:

  • Greater energy efficiency: because the system will run at a constant current for longer periods of time.
  • Saves you money: when the system runs at a constant current, it doesn’t have to use extra energy to keep restarting.
  • Low installation costs: the smaller the system, the less expensive to install.
  • Easy to maintain.

The problem with deciding on a smaller system is that you may just go too small. If it’s too small, as you might guess, it can’t properly heat and cool your home because it doesn’t have the power to do so.

The best size system you can get is one that is tailored to your home’s specifications. A properly-sized system is much more efficient and comfortable than any smaller or larger system can ever do.

Stay tuned for part three of this guide on choosing the right size HVAC system for your home! We’ll focus on how you can find an honest HVAC contractor to perfectly size your system and install it.
