Denver Residential and Commercial Air Conditioning Repair and Maintenance

As an HVAC contractor, you might think our answer is always going to be, "replace" so you need to buy new equipment, but that's not the case.  Sometimes it does make much more sense to simply repair a piece of equipment than replacement, if possible.

Repairing and preventative maintenance will enhance the comfort in your home or business dramatically and save you money on your utility bills instead of having to completely replace your air conditioners and cooling systems before necessary.

Denver Air Conditioner Repair and Maintenance

Our specially-trained Denver air conditioning repair technicians can maintain your current air conditioning system to prevent costly repairs and breakdown headaches.

An air conditioner quickly loses efficiency and cooling capacity when the indoor coil or the outdoor condenser gets dirty.

The reliable Pasterkamp Pros are also experts at repairing all makes and models of air conditioning units should the need arise. Many homeowners and business owners become lifelong Pasterkamp customers after experiencing the Pasterkamp customer service and expertise.

Air Conditioning Efficiencies

Air Conditioners are given a number which represents how efficient an air conditioner would be if it is kept clean, maintained, and installed properly. This number is called an air conditioning SEER rating (Season Energy Efficiency Rating).

What does SEER rating mean for me?

SEER rating determines the efficiency of your air conditioning system. Older air conditioners can be as inefficient as a 6 SEER or worse, and some air conditioners that are only a few years old can be rated at 10 SEER. Our most popular are ranked 13 SEER or higher.

When it comes to your air conditioning and cooling needs – Pasterkamp is your Denver ac repair specialist that can handle that!
