Furnace Repair Services in Conshohocken, PA
- Locally Owned & Operated
- Trust & Transparency
- Long-Term Relationships
A rowhome on the Conshohocken hillside heats itself differently than a detached house. Shared walls cut heat loss on two sides, but the stairwell running the full height of a narrow three story building behaves like a chimney, pulling warm air upward and drawing cold air in at the bottom. The top floor bakes and the first floor stays cold.
Davis Modern Heating & Cooling repairs heating equipment throughout the borough, in century old rowhomes and in the townhomes and condos built over the last two decades. We have been family owned since 1850 and we service every brand across all fuel types.

Heating Problems Worth Calling About
These are the heating complaints we hear most often in the borough.
- First floor never warm
- Top floor overheating
- Furnace running constantly
- Ignition failing repeatedly
- Cold drafts near doors
- Banging in the ductwork
- Equipment locking out
- Utility costs climbing
- Burnt smell at startup
- Gas odor of any kind
A gas odor means getting out of the building first and calling from outside.
Three Floors, One System, and a Steep Hill
Stack effect is the defining problem in a tall, narrow house. Warm air rises to the top floor and escapes through the roof and upper openings, and the pressure that creates pulls cold outside air in through the first floor and the basement. The furnace runs longer to compensate and the spread between floors never closes.
The grade the borough sits on makes it more pronounced. Homes up on the hill take more wind exposure than those near the river, and the pressure difference across a building on a windy January night is enough to change how the whole house heats. Two homeowners a block apart can have very different experiences of the same weather.
Mechanical space is the last constraint. Equipment crammed into small basements, closets, and utility spaces gets less combustion air and less service access than it should, and in newer townhomes the furnace often sits above living space where a drainage issue becomes a ceiling problem quickly. Tight construction leaves little room for error.
Heating Repair in Tight Mechanical Spaces
We repair and install gas, oil, propane, and electric furnaces, along with boilers, heat pumps, thermostats, ductwork, and ventilation, on all brands. In dense construction we also handle the practical questions, including where equipment can be serviced from and how venting can be routed safely.
A heating call covers ignition and flame sensing, fuel pressure, blower performance, safety controls, venting and combustion air, temperature rise, and a heat exchanger inspection. In buildings this tight, combustion air is not a formality, and we check it every time.
When replacement is warranted we explain how we got there and what will physically fit, including high efficiency options across every fuel type. We also bring more than thirty five years of experience with geothermal heat pumps and solar heating for properties where those apply.
Working a No Heat Call Above Fayette Street
Joe called from a rowhome on the hill above Fayette Street in January. His furnace was running nearly nonstop, the third floor was too warm to sleep in, and the living room on the first floor never got above sixty six.
Our technician found a filter restricting airflow, a supply damper closed on the first floor, and significant duct leakage in the basement releasing heat before it reached the living space. We replaced the filter, cleaned the burners and flame sensor, sealed the duct runs, and rebalanced the supply toward the lower floors.
Runtime dropped and the spread between floors narrowed considerably. The equipment had been healthy the whole time, it was simply losing a third of its output before that heat ever reached a room.

Frequently Asked Questions
Why is my top floor hot and my first floor cold?
Warm air rises through the stairwell in a tall narrow home, which draws cold air in at the bottom. Balancing the supply and sealing ducts usually narrows the difference.
Do you service furnaces in condos and townhomes?
Yes. We work in condos, townhomes, rowhomes, single family houses, and commercial spaces.
Is emergency heating repair available?
Yes. Our technicians are on call 24 hours a day, seven days a week.
Does my furnace need dedicated combustion air?
It needs adequate combustion air, and in a small, tight mechanical space that often means a dedicated provision. We verify it on every heating call.
Can duct sealing lower my heating bills?
It often does. Duct leakage in an unconditioned basement releases heated air before it reaches the rooms you are paying to warm.
