Stay Ahead of Seasonal Changes in Derby

Derby’s riverfront setting and rolling hills bring quick weather shifts — humid, heavy air in summer and sharp, cold winds in winter. Edgerton’s seasonal HVAC maintenance keeps your system ready for these transitions.

In spring and early summer, our tune-ups include coil cleaning, thermostat calibration, refrigerant inspection, and airflow balancing to prepare your AC for peak performance. In the fall, we switch gears — inspecting furnaces, heat exchangers, safety controls, and filters to prevent winter breakdowns.

We understand how Derby’s microclimates — from the river valley to elevated neighborhoods — affect HVAC performance. That’s why Edgerton’s preventative maintenance plans are customized to local needs, improving reliability and extending equipment lifespan while keeping your home’s comfort consistent year-round.

I've used Edgerton for about 11 years for all my HVAC issues, including annual maintenance, new furnace and A/C unit, new hot water heater, as well as the most recent job replacing all my attic and crawl space ductwork. They were very responsive, competitively priced and did an excellent job completing it on time.

Whenever I call, the people are always so helpful and nice. If there are any problems (which are rare) they are usually efficient with helping and resolving them. I always appreciate the maintenance people taking the time to explain and talk to me when I have questions or concerns. I've had my AC unit for almost 19 years, and it is still working efficiently thanks to the hard work of Edgerton. Usually by this time others would be telling me to replace it, but thanks to the hard work of the maintenance people, it's still working efficiently and they've told it still has plenty of life left in it. Don't need to change what's not broken.
