Air Conditioning

For a place that grows as hot as Round Rock, TX during the middle of the year, air conditioning is a major comfort priority. Does your home have an AC prepared to tackle the heat extremes? If the answer is "no" or "I’m not sure," then pick up the phone and call us right away. We install the top makes and models of air conditioners, so if you need a new system or a replacement, you can trust us to supply you with the right one. If you require repairs to get your air conditioner working once more, our technicians will arrive fast and get the system back in shape in no time.


Our technicians are also experienced with keeping homes cozy through the winter months. We install a variety of furnaces (electric and gas) as well as heat pumps. When you leave the work to us, we will make sure that you have a heating system matched to your household’s needs and which will work at high energy efficiency. You can also entrust any repair job to us, and we will see that it is done right. Our routine maintenance service will help your heating system run for many years at peak condition, and with few repair issues.

Indoor Air Quality

We’re concerned about the health and comfort of your family, which is why we also offer indoor air quality services. If your home is suffering from too many pollutants and contaminants circulating through the rooms, we will install air purification and/or air filtration systems to trap them and provide you with cleaner air. Our technicians are also experienced with duct testing and duct sealing, which will help keep your ventilation system free of contaminants that will lower its air quality.


Your attic is a source of excess heat in the summer and excess heat loss during the winter. We have solutions that will improve your attic ventilation for better comfort around the year and less stress on your HVAC system. We install solar–powered attic fans that use the power of the sun to ventilate your attic throughout the year. Call us today to find out more about our ventilation services.

Commercial HVAC

A business that lacks an effective air conditioning and heating system will soon find itself in trouble when the thermometer rises or climbs. Express HVAC Service will see that your business doesn’t encounter problems during any temperature extremes. We have experience and skill with installing and replacing commercial HVAC systems, and also with providing targeted repairs and general maintenance. You don’t want to risk the productivity of your business on the work of amateurs: give us a call to schedule all your commercial HVAC needs in Round Rock, TX and the surrounding areas.
