High Performance Energy Testing
Serving Mesa, Gilbert, Scottsdale & Surrounding Communities

Schedule a High Performance Test with John's AND Stop Getting Soaked by Your Energy Bill.

A central air conditioning system can work a lot more efficiently AFTER John’s has conducted a High Performance Test on your home.

Sure, you can get the power companies to do the testing for you.  But theirs are highly limited, pretty much confined to identifying  holes in your home and duct system, as well as obvious signs of poor insulation performance.

At John’s Refrigeration we recommend a whole house approach with people who understand how your home, duct system, A/C system, and insulation work together.

That way, we can effectively provide you with the full and true value of what High Performance Testing is all about: 

• Reduced energy bills by ensuring you have the right size system.
• Proper insulation, effective air flow, and no leaks in your ducts or anywhere else that could allow cool or warm air to escape into your garage, attic, or other non-living spaces.

Here’s how John’s Refrigeration goes about accomplishing just that:

Proper Sizing of Equipment

Installing the right size equipment for the home is essential to getting the best performance and comfort. Many homeowners believe that bigger is better when buying new heating and cooling equipment. But in reality, a system that's too large will not keep your home comfortable because of frequent "on/off" cycling. Incorrect sizing can also put stress on system components and shorten the equipment's lifespan.

Duct Efficiency Test

To perform this test, we employ an air ood to compare air in vs. air out.  This tell us whether or not we have duct leakage, how much air the unit is delivering, proper duct size and installation.

Sealing Ducts

To ensure that ducts are properly sealed we test the leakage rate. If the ducts are very leaky (i.e. more than 20% of the air moving through the system is leaking into spaces you do not want heated or cooled) we’ll seal with the best materials for the job. After that, we insulate your ducts to protect them from excessive heat and cold.

Proper Refrigerant Charge (Central Air Conditioners and Heat Pumps Only)

A properly charged heating or cooling system will operate more efficiently and help prolong its life. After testing your system, we’ll make appropriate adjustments, as required, by adding or removing refrigerant. 

Optimizing Air Flow

If air flow in your heating and cooling system is too high or too low, you may confront problems and higher utility bills. We test and adjust accordingly.

Proper Installation

Even the best of home heating or cooling equipment can’t compensate for poor installation.  So don’t just buy…ask lots of questions.  Get referrals.  Because once you do, we’re confident you’ll choose John’s…

…for the best in year-round indoor comfort.
