How do I choose an HVAC contractor in San Marcos TX?

Here are the top considerations when choosing a heating and cooling company:

  1. They offer the best solutions for your problem. No matter what problem you are having with your air conditioning system they need to have the best and most efficient solution. They should first listen to your needs and explain how they are going to fix it. 
  2. Expertise and Trust: your HVAC system is probably one of the most costly items in your home and you don’t buy one every day. See what your San Marcos neighbors are saying about our 5 Star Services over the last 3 decades. 
  3. Free Estimates - they should offer a free estimate on the services that they will be performing. At a minimum, if they do charge a fee to come out, it should be included in the service if you decide to hire them. 
  4. Licensing - they need to be a licensed professional. The vast majority of HVAC pros are licensed but just check and make sure before hiring them. 
  5. How involved are they in your local community? We’re glad for the opportunity to give back to Hays County for 3 decades. Check out our yearly Gift of Heat community service.

Out with the old, in with the new




Review of Garner Heating & Air Conditioning, Inc.

Max inspected my old system and gently explained the extensive damage caused by a lightning storm power surge from a few months back. Chase came out and helped me pick the best system for my house. The installation team did a fabulous job installing my new Carrier system. No scratches on the floor, the cat remained safely inside, Jason patiently answered all my questions along the way, Angel leveled the outdoor condenser perfectly, and Ethan explained the new system and thermostat thoroughly. Everything looks great! Thanks, Garner!

Performed the AC tune-up and everything is working at this time. While performing the inspection I did notice that when the roof was replaced, they pushed the flue pipe down about 8". I informed the client, and she chose to have me re-adjust the flue pipe so that it is at an upward draft all the way out of the house. I did also talk to the client about surge protection, and she wants to wait until our next visit.

After performing the diagnostic, I found that the primary drain line was backed up and bypassing the secondary drain pan. I presented the client with his options, and he chose to have the drain line cleared and treated at this time. I did discuss the other deficiencies with the system, and also discussed the maintenance plan, however he declined because he is selling the house in the next month. I performed the drain treatment and system was operational. While I was collecting payment, I heard the condenser cycle on and off multiple times. I performed further diagnostics and found that the zone control board on the indoor unit was failing. The client chose to have that replaced as well at this time. I replaced the board and tested the system.

After performing the diagnostic, I found that the system was completely empty on refrigerant. I found multiple leaks in the welds on both the indoor unit and the outdoor unit. I presented the client with his options to repair the welds, pressure test the system, pull a vacuum on the system and recharge the unit with R-410A refrigerant. The client agreed to all repairs. While completing repairs, I also noticed that when they installed the system, they did not put wire nuts on the low voltage connections leaving the bare wire fully exposed. I added wire nuts while performing repairs. After performing the repairs, the system is on and working at this time.
