Why Choose Us?

We aren’t going to tell you how we think we are better than every other contractor. In fact, the mid-west region of the united states is home to some of the best Air Conditioning professionals in the world. Climates range from extreme heat to extreme cold, unlike to many places on earth.

All we can say is, we do it the right way.

Our installers make custom piping for each project. The benefits of this technique help ensure a leak free, long lasting cooling system. Making custom bends and swage connections will reduce the amount of fittings needed. Using less fittings not only reduces the risk of a refrigerant leak, but also minimizes the chance of copper oxide developing during the brazing process.

And your wondering “What do we do about the copper oxide”? Simple, we braze with nitrogen like your supposed to. Using low pressure nitrogen while brazing not only ensures no copper oxide will develop, the process also purges any air that may be in the system making for a better evacuation.

Have you seen a furnace in the house and think “Look at that terrible duct work”?

Don’t worry, we can fix that for you. 

Sub-Cooled Heating and Air Conditioning makes a custom transition for each install out of 26 gauge sheet metal. Quality sheet metal work not only looks great, but helps airflow performance. Proper airflow is key to getting the most efficient heat transfer out of your home comfort system.

Maintenance Agreements

A lot of times when we find furnaces or air conditioners beyond repair, it is largely due to lack of maintenance over the life span of the equipment. There are some things residents can due such as change the air filter and clean the outdoor condensing unit. Whether you don’t have time, or you just don’t want to do it, having your heating and cooling system professionally cleaned and inspected is good insurance for a reliable season.
