Furnace Installation & Replacement in Middletown, DE

Delaware licensing reinstatement in progress. KelAire is not yet scheduling service in Middletown, DE. We are currently serving Maryland, and Delaware appointments will open as soon as our Delaware HVACR license is active. Join the Middletown waitlist to be contacted first.

KelAire HVAC is preparing to bring furnace installation and replacement to Middletown, DE. We are a family owned company from nearby Millington, Maryland, led by a Maryland state master licensed technician, and we are finalizing Delaware licensing now. This page is here so Middletown residents can learn who we are and join the waitlist for when Delaware scheduling opens.

Middletown is one of the fastest growing towns in Delaware, eighteen minutes from our shop. Middletown is only about 18 minutes from our Millington shop, closer than most of the Delaware companies that currently serve it. We already know the housing stock, including large developments like Willow Grove Mill and The Ponds where thousands of builder-installed systems are hitting the ten to fifteen year mark together, and that local knowledge will show up in the work from day one.

One thing we see a lot around Middletown: big-box retail and restaurant space along Route 301 with serious commercial HVAC needs. It is exactly the kind of situation where having a local, master licensed contractor a short drive away pays off.

How We Approach the Work

Two-stage and modulating furnaces earn their keep in our climate, where most winter days need a fraction of full fire. But they only deliver if the ductwork can breathe and the installer commissions them properly. That commissioning step is standard on every KelAire install, not an upsell.

“We used KelAire HVAC to install a new heat pump and furnace. We obtained several proposals. Doug Kelley took the time to explain everything.”

Why Middletown Should Know KelAire
