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.

Review of Garner Heating & Air Conditioning, Inc.

Garner heating and air helped us as soon as they could after the Polar Vortex of 2021. They helped us through the repair and replacement of our old system and even helped me work with my insurance company. All the works are great, helpful, and kind. Their office staff was great to work with also, always being polite and helpful. 5 Star in my opinion!!

The company stayed in touch with use through the rolling blackouts and arrived as soon as they possible could and the power was on. The receptionist was great about working with us.

When I arrived, I found that the TXV had completely failed. This is the 3rd one that has failed since it was installed back in 2018. Due to this I spoke with our Service Manager Ryan, and we are going to replace the entire evaporator coil, liquid line dryer, pull all of the refrigerant, flush the lines and recharge the system with all new refrigerant.

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.

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.
