Review of Garner Heating & Air Conditioning, Inc.

Ray was thorough, professional, and efficient in completing his check list for my A/C system today. He thoroughly explained some new products and improvements that could be added to the system and gave me brochures explaining the components and advantages of some of the new products. I did not receive a bill this time because I think I have paid for this service prior to this visit. I do not have a Facebook account or a Google Business Page.

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. Likewise, no one should be without heat in the winter- our team has years of experience trouble shooting and repairing air conditioners, heat pumps, and gas furnaces. All of our repairs come with a year long guarantee- we are committed to customer satisfaction.

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.
