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.

Diagnosed that the float switch in the secondary drain pan was tripped due to water. After clearing the drain and emptying the pan I turned the system on. I then found that the system was not getting voltage from the thermostat. I checked voltage from the board and the thermostat and power was not sending a signal to run the system in cool. I tested the system by jumping to the y wire. System ran with no issues. I then presented customer with options to replace the thermostat, but they declined.
