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.

After performing the diagnostic, I found secondary drain pan to be rusted and have water in it. I also found the voltage enhancement system inside the condenser to be weak and undervalued as well as the voltage enhancement system for the blower motor. I presented the customer with his options and he would like us to call him and schedule a time to come out here to do the work.

After performing the diagnostic, I found that the primary drain line was completely blocked causing the safety float switch to trip and therefore cut off the system. I called the customer and presented him with his options, and he chose to have it repaired.

When I arrived, the customer informed me that there is a pipe that cuts the corner of the sheet rock at the ceiling and the exterior wall. I found that the line set was not run through the header of the exterior wall before it went down. I informed the customer of my findings, and she chose to leave it until the system is replaced. After discussing the pipe, she asked me if I could check the refrigerant pressures. After checking the pressures, I found that the system is low on refrigerant. I presented the customer with her options on this repair, and she chose to do the work at the bronze level. The system is installed poorly and looks to be in poor condition. It is operational at this time.

When I arrived, the customer asked me to look at the evaporator coil to see how dirty it was. After opening the system up and looking at the 14-year-old evaporator coil it is in clean condition at this time. However, I did notice that the drain line and secondary pan had some issues and I addressed this with the customer. The drain pan is slightly off from underneath one of the corners of the air handler and has rust and corrosion at the bottom of it. I also noticed that there is no way to clear through the drain line and it does not have any safety switches in the drain line. I did present options to have the secondary drain pan replaced. The options also included re-piping the primary drain line with the installation of safety float switches in both the primary drain line as well as a secondary pan to prevent any sheet rock damage from the pan overflowing. The customer declined all repairs at this time.

After performing the diagnostic, I found that the low-voltage wire going to the condenser had a short in it causing the fuse to pop. I was unable to check over the electrical inside the condenser because it is a solid block of ice from the weather conditions outside today. I presented options to the customer for running a new wire and he chose to move forward with the repair, but we will need to wait until weather conditions improve. I will have our office reach out for scheduling next week. They do have electric heat running at this time however I did have to remove the wires going to the condenser so it would not pop the fuse again.
