Air Conditioner Installation

The most critical day for your air conditioner is the day it is installed. Studies show the majority of air conditioners are not installed correctly. This means most homeowners are not getting maximum efficiency, comfort, and longevity out of their air conditioning installation. If the air conditioner is either oversized or undersized, the homeowner will not get proper humidity or heat removal.

We ensure your air conditioning installation gives maximum benefits. Our NATE-certified air conditioning technicians will also ensure you get the maximum return on your investment. With Dunn Plumbing, Heating & Air Conditioning, LLC, our 100% satisfaction guarantee for all our air conditioning services ensures value and peace of mind.
