As always, great service!




Had a problem with suddenly excessive humidity in the house (near 100%). Called Garner, and they were at our door before I hung up the phone (wellll, not really, but almost). They made a thorough check of our system (previously installed and regularly maintained by Garner), but found everything was in perfect working condition. They did discover that we had inadvertently changed a thermostat setting, which caused the problem. Simple fix, but which should have resulted in a $75.00 service call, which they kindly waived. We have the annual service plan, that gives us twice-a-year system checks and priority scheduling and discounts for service. That, and dealing with a company that’s totally honest, fair, friendly and highly skilled, makes it so worth it. Can’t say enough good things about Garner Heating & AC.


Ryan and the rest of the team did a great job in installing our new ac and heat units. They were all polite and respectful. Ryan had great recommendat




Awesome job and people.

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.
