AC Replacement San Marcos, TX

Heating and air conditioning replacement is an unavoidable eventuality, even with excellent maintenance. Once it becomes clear that your heater and AC needs to be replaced, our technicians will evaluate your space and your needs to design a superior system that will provide you with the comfort you deserve. Everything from duct work, vents, and airflow will be considered and optimized, to help save you money in energy costs and ensure the efficiency and longevity of your new system.

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.

When I arrived, I found that the system is in poor condition and freezing up. They chose to have it replaced and we will be back on Nov. 29th to install a new system.

I called the customer to let them know I was on the way, and they informed me that the system was throwing a code. When I arrived and turned the power back on to the system everything fired up and ran without turning off for 30 mins. I contacted the customer to let them know and offered our maintenance plan. They declined maintenance and will contact us if any more issues arise. System operational.

After performing the diagnostic on the living room system, I found that the primary drain line was backed up and tripping the safety float switch. I presented my findings to the client and proceeded to complete the repair on the drain. After the drain system was working properly again, I tested the system and then found that the battery capacitor had failed and was not sending the correct voltage to the motor and compressor. I presented the clients with their options, and they chose to have the capacitor replaced and sign up for maintenance on both systems. I completed the capacitor repair and the system is now fully operational.

Diagnosed a failed capacitor on the outdoor condenser. In addition to the capacitor, there are numerous other problems with the system. I would like them addressed when we come to perform the maintenance on the system. Replaced capacitor and system is now operational.

Re-piped the primary drain line and installed a new safety float switch. I also installed a ball shut off on the other drain that ties into this one for clearing purposes. Cleared and treated the drain line and everything is draining properly at this time. Also found that the other system that controls the back offices is extremely undersized on return air. I informed Justin and I will be discussing with our Service Manager to find a good solution for this issue. We will send over an estimate in the next day or so.

After performing the diagnostic, I found the water was inside the wall at the floor level and the AC system was upstairs in a closet. The drain was not backed up, so I have determined that the AC is not the issue. The customer will call a plumber to further diagnose.

After performing the diagnostic, I found that the system that controls the back office is a solid block of ice and will need to thaw naturally before we can determine the problem. I also found that the drain for the system behind the bar is backed up and we will need to re-pipe it to clear and treat. They are going to call the owner and get approval for this, and we will complete the work when we return to take a look at the other system.

AC Repairs San Marcos, TX

When repairs to the HVAC system are needed, our N.A.T.E. certified technicians will quickly get your equipment back on track. Living without cold AC in the summer is not an option in Texas.

AC Maintenance San Marcos, TX

Maintaining your heating and cooling components is incredibly important for the longevity of your system. Regular twice a year cleanings and tune ups will keep things running smoothly and save you time and money in the long run. A poorly running system will not only impede your ability to stay cool in the summer and warm in the winter; your energy costs will skyrocket as your system runs overtime to compensate.

Our A/C and heat experts will work diligently to thoroughly remove dirt and debris, which can quickly cause many of the common problems associated with poor performance and the shortened life span of your system. They will evaluate your equipment, catching potential problems before they become heating and air conditioning emergencies. Scheduling regular maintenance also has the added benefit of keeping the air quality in your residential or commercial property healthy.
