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.

The homeowner informed me that the system on the garage side had been making a popping noise at the disconnect and that the lights had been flickering inside. I made a note of that and went over both systems. I made sure to get the drain lines cleared and did a thorough rinse on both condensers. I also made sure to remove the leaves and debris from the bottom of both condensers. I discovered that the disconnect on the garage side AC has burnt and pitted contacts that were arcing when voltage was applied. I made the homeowner an option to get that disconnect replaced and he elected to have me do the work. I replaced the disconnect and made sure everything was nice and tight. Overall, the systems are in decent shape. They’re both in operational shape and running much better now than they were. Systems are in working order at completion of service. See attached checklist for full tune-up details.

Garner heating and air helped us as soon as they could after the Polar Vortex of 2021. They helped us through the repair and replacement of our old system and even helped me work with my insurance company. All the works are great, helpful, and kind.
