Serving Montgomery County Since 1966

During the scorching days of Summer and the coldest days of Winter your cooling and heating systems protect you from the unpredictable weather outdoors. The majority of homeowners will constantly check their thermostats, but it never crosses their minds to check anything else beyond that, like their air ducts. Homeowners always expect to have their HVAC systems in tip-top shape, but emergencies can occur and those systems can sometimes fail. 

Fortunately, the skilled technicians of Long Air Conditioning, INC are trained to aide you during these types of emergencies and our staff is on call 24 hours a day, 7 days a week. Our team will head to your home, inspect the problem, find a solution, and get your systems back up and running in no time! One of our goals is to ensure our customers in Montgomery are living to their fullest comfort.

Broken air conditioning units and furnaces can take us by surprise most of the time, but there is a way to make sure you stay ahead of any issues. For instance, regular service calls and routine maintenance are highly recommended to ensure your heating and cooling systems are operating to the best of their ability. Our technicians are more than happy to help you schedule annual appointments to get the job taken care of.

Homeowners must remember though that eventually some units will meet their doom and nothing can be done to bring them back. As tragic as this sounds, our team at Long Air will always come to your rescue! We have a variety of Trane products that have been tested in the harshest conditions and guaranteed to bring you unstoppable home comfort.
