Heating & Cooling Services in Nashua, NH

Heating, Cooling and Heat Pumps for Nashua Homes

Nashua has a wide mix of housing: older homes and multi-family buildings near downtown, mid-century neighborhoods, and many newer single-family homes and subdivisions. Courtesy Heating and Cooling serves Nashua homeowners with heating, air conditioning, heat pumps and ductless mini-splits, water heaters and geothermal systems.

Forced-Air Homes: Furnaces, Central Air and Ducted Heat Pumps

Many homes in the Nashua area have forced-air heating with ductwork, which opens up options. A high-efficiency natural gas or propane furnace can replace an aging unit. Central air can share the same ducts, and a ducted heat pump can provide both heating and cooling. If your ducts are in good shape, these systems can heat and cool the whole home efficiently. See our furnace installation and air conditioning installation pages for more.

Ductwork matters, though. Leaky or undersized ducts can make some rooms uncomfortable no matter how good the equipment is. When we evaluate your system, we look at airflow along with the furnace or air conditioner.

Homes Without Ducts and Hard-to-Heat Rooms

For older homes with boilers, or for additions, bonus rooms over garages and finished basements, ductless mini-splits are a flexible solution. Each indoor unit has its own control, so you can fix one problem room or zone the whole house. Learn more on our heat pump and mini-split installation page.

Repairs and Maintenance

When your heat stops working on a cold night, or your AC quits during a heat wave, we’re here to help. We offer heating service and AC service, plus seasonal heating and cooling maintenance to keep equipment running efficiently. We also repair and replace water heaters and offer geothermal services.

Choosing the Right Replacement System

When it’s time to replace a furnace or air conditioner, you have more options than you might think. You can replace like-for-like with modern, high-efficiency equipment, or switch to a ducted heat pump for both heating and cooling. A dual-fuel setup combines a heat pump with a gas or propane furnace. We’ll help you compare installation scope, comfort and operating considerations so you can pick what fits your home and budget. Proper sizing with a load calculation makes sure your new system isn’t oversized or undersized for your home.

If you’re finishing a basement, building an addition or converting space over a garage, plan heating and cooling early. Extending existing ductwork isn’t always the best answer. A dedicated mini-split often gives better comfort and control in a new space.

Seasonal Tips for Nashua-Area Homes

• Change furnace and air handler filters regularly, more often during heavy use.
• Keep supply and return vents open and unblocked by furniture or rugs.
• Clear snow and ice from outdoor heat pump units and high-efficiency furnace vent pipes after storms.
• Book heating maintenance in the fall and cooling maintenance in the spring, before peak seasons.

Frequently Asked Questions

Can I add a heat pump to my existing furnace in Nashua?

Often, yes. Pairing a heat pump with a furnace, sometimes called a dual-fuel or hybrid setup, lets the heat pump handle much of the heating and cooling while the furnace covers the coldest weather. We’ll check whether your home and ductwork are a good fit.

Why are some rooms in my house always hotter or colder than others?

Common causes include duct design or leaks, airflow problems, insulation differences and thermostat placement. A mini-split for one problem room or adjustments to the existing system can often help.

Do you install both furnaces and boilers?

Yes. We install natural gas and propane furnaces as well as oil and gas boilers.
