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.

  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.

Performed the maintenance checks on both mini-split systems. Both systems are working at this time. When I arrived Mr. Janes informed me that one of the systems seemed like it wasn’t keeping up the way it supposed to. I believe it was due to a setting on the remote because once I reset it to auto everything was working the way it was supposed to.

After performing the diagnostic, I found there were 2-inch media filters inside the air handler in the closet. I also found that the condensing coil is dirty however there is no way to hook up a water hose and wash it so we will have to bring a sprayer back to be able to clean the condensing coil. After the system ran for 20 minutes the other condensing fan motor started pulling high amps. It started pouring down rain and I was unable to complete this job at this time. We will be returning tomorrow to replace the condenser fan motor and wash the condenser coil.

1st trip – Performed diagnostic and found mini split blower wheel caked with dust and debris causing lowered cooling efficiencies and drainage issues. Outdoor condenser also building up debris and dust. Customer would like to have wheel head and condenser cleaned. Payment collected and we return next week to complete the repairs. Also, this mini split is on a two-zone head and we will address second head when we return. 2nd trip – While preforming cleaning I found traces of oil. I completed a leak check and found a leak in the coil. I discussed my findings with the customer presented options for head replacement. System has been cleaned and is operational. The replacement head is on backorder with Carrier but if customer moves forward with head replacement, a $200 credit will be issued on the work. We will send an estimate for the work, prior to the credit, to the customer.

Performed cooling tune-up on 2 Lennox gas systems. On the upstairs system I found that the voltage enhancement system at outdoor unit was under tolerance. I presented repair options to the customer and they decided to move forward with the work. I replaced the voltage enhancement system to upstairs condenser and voltage performance systems were added to both condensers. Performance and safety tested was performed on both units after repairs completed and I also washed off the outdoor units.
