Air Conditioning Services

If you’re in the market for a new air conditioner, look no further. We offer free estimates-something you’re not just going to find from every HVAC contractor-to help you find out which air conditioning system will work best in your home. Whether you installed with us or not, we’re also happy to take a look at your air conditioner for repairs or maintenance.

AC Repair

Has the performance of your AC been on the decline? Are you noticing higher cooling bills? Or, maybe your AC is making loud noises and crying for help. AC repair needs come in many forms and may not always be obvious. When you suspect something isn’t working right with your AC, you can count on Thayer Air Conditioning to find the issue for you. It’s important that you do call in any strange behaviors, since prolonged repair issues can make the problems even worse.

AC Installation

When it’s time for a new air conditioner, whether it’s your first or if you’re replacing an old one, depend on us for fast and reliable AC installation. We’ll do a thorough inspection of your home to help find the best system for you, and we’ll do it as part of our free estimate. Whether you need a central AC, heat pump, or one of those fancy new ductless mini split systems, we can help you find the AC that’s right for your needs and install it, too.

Heating Services

What makes heating services different with Thayer Air Conditioning? For one, we only use American-made systems and parts. And second, we always start with a free estimate, upfront pricing, and a 10-year worry-free guarantee on new systems. For heating systems that use natural gas, it’s especially beneficial and vital to your safety to work with a professional. If you’re working with an amateur, they won’t be able to assure the success of their installation and repairs.

Heating Installation & Repair

There are several factors to consider when installing a new heating system in Seguin, TX. Fuel type, efficiency rating, features, existing HVAC system… The average homeowner isn’t expected to know all these things for their new system. Yet, knowing about those factors is crucial to picking the right heater for your home. Our technicians will walk you through the entire process so you can end up with the heating system that you deserve.

Commercial HVAC

HVAC services in the home will always put homeowners on the fence: is it a luxury, or is it a necessity? But for commercial spaces in Seguin, the answer is a definite "necessity." Fortunately, we have several years of experience in the field of commercial HVAC, having worked with name brands like 7-Eleven and Circle K. We can set you up with refrigeration, ice machines, and draft beer systems for your business. Plus, we do all the traditional HVAC services like heating and cooling.

Indoor Air Quality Services

Have you ever seen bits of dust floating through a sunbeam? Those represent just a small fraction of the particles that are visible with the naked eye. There are millions more that you can’t see and are capable of triggering allergy and asthma symptoms, as well as capable of making you sick. In the worst cases, some can even create long-term health effects. We offer a range of indoor air quality products to clean your air space and increase your general comfort.
