At Perennial DC Heat Pumps we install ducted air-source heat pumps and handle the work around them across Washington, DC. Pick the service that matches the equipment you have and the result you want, and each page explains what changes the job, what we can keep and what goes in our written estimate.
Heat pump replacement
If your heat pump is old, loud or keeps needing repairs, we start with why it disappoints you before we pick the replacement. We handle ducted heat pump replacement across DC and set the scope from your existing equipment, the house and what you want fixed. When an upstairs bedroom never cools, buying the same nominal size again usually keeps the problem, so we separate a worn-out part from a system that was designed wrong.
Replacement makes sense when the system has a documented failure, keeps needing repairs, has mismatched parts or no longer suits the house. Age tells us where to look, but it isn’t a defect or a deadline on its own. A repair fixes one identified fault; our replacement estimate also tells you the condition of everything we plan to keep, so you can compare the two honestly.

Cold-climate heat pumps
Whether a heat pump keeps up on the coldest mornings depends on the model and the house, not the label. We install cold-climate heat pumps for ducted air-source projects in DC, and we check the matched system’s heating output at the local design temperature against your home’s calculated heat loss. A system can be efficient across the season and still need a clear backup plan for the coldest days.
Cold-climate equipment is built to keep heating well at low outdoor temperatures. That makes it worth considering where winter output matters, but it doesn’t tell us the capacity your house needs. We size it from the manufacturer’s heating data for the exact indoor and outdoor pair, not from a seasonal rating or the biggest number in a brochure.

Dual-fuel heat pumps
Keeping the gas furnace as backup can make sense when it is still in good shape and works with the new equipment. We install dual-fuel systems in DC: an air-source heat pump paired with a compatible furnace, with controls that decide which one runs. We design it as one system, not an outdoor unit wired to whatever is already in the basement.
If your furnace still suits the house and has a documented, serviceable condition, we may recommend keeping it as backup. That matters most when you are weighing a full furnace conversion against a smaller change. The furnace’s condition, how it pairs with the new equipment and your own fuel preference all count; age alone doesn’t decide it.

Furnace conversion
If you want the gas furnace gone, a conversion changes how your house makes heat, and we also check whether the ducts can carry that heat to every room. We plan furnace-to-heat-pump conversions for ducted air-source projects across DC, starting with your forced-air system, the electrical needs and whether you remove the fuel backup or keep it. A boiler or radiator house is a different conversation, not a straight furnace swap.
This service is for homes heated by forced air that want a ducted air-source heat pump. Gas and oil furnaces push warm air through ducts; a radiator system carries hot water or steam. They aren’t interchangeable just because both warm the rooms, so we confirm what is actually installed before we price a conversion.

Air-handler replacement
When the outdoor unit is fine but rooms still feel wrong, the air handler can be the weak link while the heat pump outside still runs. We replace heat pump air handlers in DC as part of a matched ducted system. We start with the indoor cabinet, coil, blower, drain and controls, then check how they pair with the outdoor unit. We never pick a new air handler by cabinet size or brand name alone.
The air handler moves conditioned air through the house and, depending on the setup, holds the indoor coil and the electric backup heat. A documented coil, blower, cabinet or drain problem can justify replacing it, and we set the scope from the actual fault and the condition of what it connects to. A new cabinet won’t fix every comfort complaint, and we tell you when it won’t.

Heat pump ductwork
When the upstairs runs hot and the downstairs cold, the ducts are often why. A heat pump only keeps you comfortable if air reaches each room and finds a way back. We assess and change heat pump ductwork in DC as part of our installation and replacement jobs. We look for restrictions, leaks and rooms the ducts barely reach, then propose only the duct work your system needs. New equipment can’t make up for an air path nobody checked.
Uneven temperatures, noisy vents or a quote for a bigger system are all good reasons for us to look at the ducts. None of them points to one cause on its own. A room may need more supply air, less heat gain through walls and windows, a better return or different controls. Replacing ducts without knowing the load misses the point as much as replacing equipment without checking the ducts.

Commercial heat pumps
For a shop, office or small practice, a commercial job has to fit how the building is used, not just the equipment. We install ducted commercial heat pumps in DC within a clearly defined scope. Occupancy, ventilation, equipment access and who owns the system can make a small commercial space very different from a house of the same size, so we settle those first and price it from the site visit rather than from a residential range.
We handle ducted air-source heating and cooling where that equipment suits the building. We don’t take on VRF networks, chillers, geothermal systems, shared water loops or specialist process cooling. A heat pump label on an indoor unit doesn’t tell us which system the building really uses, so we confirm it before we quote.
