“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.

3 Ways to Protect Your HVAC from Metal Corrosion

Corroded coilDo your customers live at the beach? If so, you know their A/C systems need a little extra TLC from all that salty air.

Over time, salty air can break down the oxide layer that protects parts of the A/C from disintegrating. Check out the photo above – those A/C coils are definitely corroded!

How can you fix corrosion and protect your customers A/C systems? Sea Coast Air Conditioning of Florida has three answers in “How the Beach Damages Your AC.”

One of the best ways is to put a protective layer back on the system.

Sea Coast suggests that “applying an anti-corrosion coating to your air conditioning system can help your AC withstand exposure to the ocean air.”

So what kind of coating do you need? Try a micro-coat that is specifically engineered for metal corrosion like Coil Shield. If you use it for your customers, you can keep their coils protected and clean for one year or more. You’ll see less corrosion and buildup, and the coating unobtrusively covers the coils.

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.
