I've relied on Hamilton Heating & Air for multiple service calls over the years and Mike has always been able to identify and fix the issues quickly. When it came time to replace our entire HVAC system, the experience was smooth. The lead time was faster than expected, installation was quick, and he even went out of his way to lend a portable AC unit while we waited for the new system. Mike is responsive, dependable, and has a level of customer care that's harder to find. I'd highly recommend Hamilton Heating & Air, LLC for any HVAC needs.
Heating & Cooling Installation in Stevensville, MD
A new system sized for the house it goes in, set clean and tested before we leave.

Installation
Heating & Cooling Installation for Kent Island Homes
A new heating or cooling system is a big decision. It should fit your house, not a guess. Hamilton Heating & Air installs furnaces, heat pumps, central air and air handlers. We work in homes and businesses on Kent Island and across Queen Anne's County. We size the system first, then set it, then test it.
Sized for your house
We look at the size of the home, the rooms that run hot or cold, and how you use the space.
Clean, careful installs
New pads, neat line sets and tidy connections, whether the unit sits outside, in a closet or up in the attic.
Tested before we go
We run the new system and check it over before the job is called done.

How It Works
Three Simple Steps
Call or Send the Form
Reach us at (301) 748-9345 or send the form. Tell us what the system is doing.
We Diagnose & Recommend
A technician looks at the system, finds the cause and explains your options.
We Install or Repair
Once you approve the work, we do it and check the system before we leave.
When Replacing Beats Repairing
Sometimes a repair is the smart call. Sometimes it is money spent on a system near the end of its life. If your system needs a big part, runs all the time, or leaves rooms uneven, a new one may make more sense. We lay out both paths and let you decide. Nothing starts until you approve it.

Attics, Crawlspaces and Tight Closets
Plenty of homes on the Eastern Shore keep the air handler in an attic or a crawlspace. Those jobs take more care. We set the unit level, run the lines neatly and seal the duct connections. Outside, we set the condenser on a solid pad, and we raise it on a stand where the yard calls for it.
What It Costs
Heating & Cooling Installation Cost on Kent Island
A new system is priced on the size the home needs, the type of system you choose, and whether the ductwork and wiring can carry it. Access matters too. An attic or crawlspace install is a different day of work than a closet swap. You get the number before any work starts.
For a price based on your equipment and the work it needs, call or text (301) 748-9345. Tell us the system type and the problem you want to solve.
