Excellent Company, Enjoy Doing Business With Them
April 26, 2023
Karnes \& Stanley has been our go\-to HVAC service company for years. They've repaired our systems several times when problems have come up and have provided bi\-annual maintenance services as well. They are always quick to respond to phone calls, will often show up after hours to assess problems, and are always willing to go the extra mile in providing excellent customer service. We recently had our entire second floor system fail and it had to be completely replaced. They came out quickly to try to fix it and then when it was determined it could not be fixed, they were able to get the replacement system quickly and get us on the schedule quickly too for the install. They've also replaced my mother's AND my mother\-in\-law's systems in recent years and their service was excellent then too. They are honest and fair in their pricing and they really take the time to take great care of their customers. I really can't say enough good things about this company. You won't be disappointed if you decide to use them for your home's heating and air needs.

Karnes and Stanley recently replaced our HVAC and added a whole house humidifier. We have been dealing with Brad Stanley for a number of years. The Karnes and Stanley team did a great job of installation and explanation of our updated system. They are friendly and efficient, and were in and out in one day, with minimum intrusion. Great people, great job. Highly recommend them.

Heat Pump Replacement
April 12, 2022
Karnes and Stanley were super helpful in assisting me in the selection of an efficient heat pump, blower and thermostat. They offered multiple options and their pricing was very competitive when compared to the big boys and their service was great. They did a nice install and cleaned up after themselves. I'm very satisfied.
