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 customer informed me that there was water coming out of the mini-split head that controls the bathroom. I poured 5 bottles of water into the drain pan and watch them flow out of the drain outside of the house with no problems. I turned the system on and let it run for about 45 minutes and could not get the system to replicate any type of moisture dripping from the system. After it ran for 45 minutes, I poured 2 gallons of water into the drain pan just to be sure that everything is free flowing at this time. Per Ryan there will be no charge at this time. I did inform the customer that they will need to keep up with changing the filters or this could happen again. I also told them that if it happens again there will be a service charge for coming out.

When I arrived, the customer informed me that the indoor system was making a strange drilling noise. I turned the system on and checked everything out and could not get it to replicate the noise for me at this time. The motor seems to be fine at this time. I informed the customer that if it happens again to give me a call so I can hear it to help pinpoint the issue.

Performed a water removal system renovation. We installed a new secondary condensate drain pan, new vibration reduction system and installed a new ceiling saver switch to trap any overflow condensate. We also rebuilt the primary and secondary drains and corrected the orientation of each that were installed incorrectly at the initial installation. We sealed the tape joints that were coming loose with mastic and hard cast. Thoroughly cleaned the condensing coil and rebuilt the voltage enhancement system on the furnace blower motor. System is in good working order at this time.

Performed the AC tune-up and everything is working at this time. While performing the AC tune-up I found the voltage enhancer to be weak and undervalued; it is rated at 40/5 and reading 7.9/2.1. I gave the customer his options and he chose to have it replaced at the platinum level at this time. After performing a platinum level voltage enhancer repair with installing a new voltage enhancer, voltage distributor and installing a new start assist everything is working at this time.

Called the customer and he informed me that it seemed like one of the rooms in the house was not cooling as well as other rooms, but he also informed me that the door is kept closed all the time. I suggested that they try cracking the door by about 4” - 5" and running it that way for a few days to see if that helps. If it does then we will have to add return air into that room.

Called the customer when I was about to start heading over to their house and she was asking me if it could potentially be the filter again. I informed her that it could be and if I came out there and found out that it was just a dirty filter again, I will have to change them again. She told me that they are going to replace the filters, let it thaw out and if it freezes up again, she will give us call back.

When I arrived, I found the mini split head in the living area to be dripping a little bit of water every now and then. I found that the drain tube had a slight restriction in it. I cleared through it again and everything is working at this time. I did inform the customer that this is under warranty from the work we did a month ago however if it happens again we will need to run a whole new drain line through the wall and that will not be covered. The drain tube that is in there now is the ribbed small diameter mini split drain hose.

After replacing the voltage enhancer and voltage distributor everything is coming on and working at this time.

When I arrived, I found the system to be frozen up. I let it thaw out and adjusted the blower speed. I checked the refrigerant pressures and temperatures, and everything is working at this time.

When I arrived it was 72 degrees inside the house. I checked the drain pan and cleared the drain line. I lowered the blower speed due to it sucking water out of the drain pan and adjusted the refrigerant pressures accordingly. I have 7 degrees of subcooling and 7 degrees of superheat and a suction line temp of 46 degrees. The suction pressure is 109 and head pressure is 349. Everything is working at this time. I did inform the customer that when it is 95 degrees outside the system is going to run all day long to keep it 75° inside. I also inform the customer that once it is over a hundred degrees outside it is going to climb from what their set point is at 72 degrees.
