Preventative Maintenance is Your Best Defense Against System Failure

We all know that a well-maintained car will last longer and perform better over its life than a car that is ignored and never serviced.

The same is true for air conditioners, heat pumps and furnaces that’s why All-Seasons Comfort Heating and Air Conditioning offers one of the most, if not the most, comprehensive preventative maintenance (PM) schedule in the Jamestown, Greensboro and High Point area. We make two visits per year. In the Spring we come out and perform a PM of your cooling system. In the Fall we also come out to perform the PM for your heating system. Most importantly, we will send you a detailed report on your system’s performance for your records. We provide two visits at one low price. We even offer a discount if you have multiple systems and one location. For complete details of what is covered with each visit please reference the schedule below.

Here's what Jack Pierson said about All-Seasons Comfort
Heating and Air Conditioning

"A thorough, professional and extensive effort on the part of Michael. Explained what he was going to do and did it. He provided an extensive report on his findings and it was easy to read and comprehend. He came out on short notice and wasted no time in performing the task at hand. He's our guy, going forward, and is also very reasonable with his pricing. Couldn't ask for better service"
