Heating Systems We Install & Replace
We install and replace gas furnaces, oil furnaces, electric furnaces, heat pumps, and geothermal systems. As a Carrier Factory Authorized Dealer, we guide homeowners through Carrier’s furnace and heat pump lineup, matching system performance to your home’s actual needs rather than defaulting to whatever is in stock.
The right system depends on your existing fuel source, ductwork condition, square footage, and efficiency goals. Here’s a quick look at what each type offers Gaithersburg homeowners:
- Gas Furnaces
The most common heating system in Montgomery County homes. Gas furnaces deliver strong, consistent heat output and perform well through all but the coldest days of a Maryland winter. - Heat Pumps
A single system that handles both heating and cooling. Heat pumps operate efficiently in the mid-Atlantic climate and include backup heat for the coldest stretches. A strong option if you’re replacing aging cooling equipment at the same time. - Oil Furnaces
Still in use in older Montgomery County homes. Oil furnace replacement often opens a path to higher-efficiency gas or heat pump systems, depending on your home’s infrastructure. - Geothermal Heat Pumps
These systems draw on stable underground temperatures for both heating and cooling, offering high long-term efficiency among heating options. A site assessment is required to determine suitability for your property.

What to Expect During a Heater Installation or Replacement
A heater installation is more involved than swapping one unit for another. We begin with an in-home consultation to assess your existing system, your home’s size and layout, ductwork condition, and comfort preferences. That assessment drives system selection, not the other way around.
What a Proper Installation Includes
A properly executed installation includes a heating load calculation to size the system correctly, ductwork connections or modifications where needed, refrigerant charging for heat pump installations, and full system commissioning and testing before we leave. An improperly sized system, even a high-efficiency one, can produce uneven heating, higher energy bills, and shorter equipment life. We don’t skip those steps.
For replacement projects, we remove the existing unit, install the new system to manufacturer and code specifications, and walk you through the operation of your new equipment before the job is complete.
Signs Your Heating System May Need Replacement
Repairs make sense for a system with useful life remaining. They don’t make sense when the system is working against you. A few patterns consistently point toward replacement as the better investment.
- Age: Gas furnaces typically last 15 to 20 years; heat pumps generally reach 10 to 15 years with proper maintenance. Systems past those ranges can carry an increasing risk of failure
- Frequent repairs: A system that has needed repeated repairs in recent years is often costing more to maintain than a replacement would cost to operate
- Rising energy bills: Higher heating costs without a change in usage patterns often indicate a system losing efficiency
- Uneven heating or unusual noises: Rooms that won’t warm, short cycling, or new sounds can all indicate a system that’s struggling to perform
If you’re unsure whether repair or replacement is the right call for your Gaithersburg home, our technicians can assess your system’s age, repair history, and current efficiency and give you a straightforward recommendation.
