Heating & Cooling Services in Dover, NH

Heating and Cooling Services for Dover Homeowners

Dover’s homes range from older houses near downtown and the Cochecho River to converted mill-era buildings and newer neighborhoods and subdivisions. Courtesy Heating and Cooling serves Dover and the surrounding Strafford County towns with heating, air conditioning, heat pumps and ductless mini-splits, water heaters and geothermal systems.

Older Homes and Converted Buildings

Many older Dover homes heat with hot-water or steam boilers, and some have equipment that has been patched and modified over the years. Converted buildings and apartments can have tight mechanical spaces and unusual layouts. When we look at a system in one of these homes, we check how it’s piped and controlled, as well as how the equipment itself is running. That helps us find problems like uneven heat, noisy pipes or short-cycling at the source.

If you’re replacing an aging boiler or furnace, we’ll walk through your options and help you choose equipment sized for your home. Learn more on our heating installation, furnace installation and heating service pages.

Adding Air Conditioning or a Heat Pump

Many homes in Dover, like much of New Hampshire’s older housing, weren’t built with central air. Ductless mini-splits are a practical way to cool bedrooms, living areas or a converted attic without installing ductwork. Cold-climate heat pumps can also heat efficiently through much of the winter, and many homeowners keep their existing boiler or furnace as backup. Visit our heat pump and mini-split installation page for details, or see air conditioning installation if you already have ducts.

Keeping Your System Running

Regular maintenance helps your equipment run efficiently and lets us catch problems before they turn into breakdowns. We offer heating maintenance before winter and AC maintenance before summer. We also repair and replace water heaters, and we offer geothermal services for homeowners considering a ground-source system.

Comfort in Converted and Multi-Level Spaces

Lofts, converted apartments and multi-level townhomes can be hard to keep comfortable. Heat rises to upper floors, large windows can make rooms run hot in summer and cold in winter, and a single thermostat rarely suits every space. Ductless mini-splits and zoned systems give you separate control over different areas, which can make a big difference in comfort. We’ll look at how your space is laid out and how you use it before recommending a solution.

For single-family homes, an upgrade is often the right time to rethink how the house is heated and cooled. Some Dover homeowners replace an old boiler with a new high-efficiency model. Others add a heat pump for cooling and a second heat source, or switch fuel types. Each option has different installation and operating considerations, and we’ll explain them clearly so you can decide.

Seasonal Checklist for Dover Homes

• Fall: book a heating tune-up, bleed radiators if needed, and test your thermostat.
• Winter: keep vents, exhaust pipes and outdoor heat pump units clear of snow and ice.
• Spring: replace filters and schedule AC or heat pump maintenance.
• Any time: call us if you notice new noises, odors, leaks or rooms that won’t stay comfortable.

Frequently Asked Questions

Do you work on older boiler systems in Dover homes?

Yes. We service, repair and replace oil and gas boilers, and we check the controls and piping, not just the boiler itself.

What’s the best way to cool an apartment or older home without ducts?

A ductless mini-split is often the best option. It needs only a small opening in an exterior wall and can serve one room or several zones. For rentals or condos, check any building or landlord requirements first.

Can a heat pump replace my boiler?

It depends on your home, its heating load and the equipment. Many homeowners use a heat pump for most of their heating and keep the boiler as backup. We’ll assess your home and give you an honest recommendation.
