Furnace Repair in Takoma Park, Maryland
Montgomery County · 24 hour emergency service
Furnace repair and installation in Takoma Park, where the house is often older than the heating system by seventy years. We work on the frame houses off Carroll Ave, the 1920s colonials along Flower Ave, and all the converted systems in between.
Why people here call us.
Takoma Park is old enough that a furnace here is rarely the first heating system the house has had. Plenty of the frame houses off Carroll Ave and Maple Ave were built in the 1890s and 1900s with coal, converted to oil, then to gas, and the furnace in the basement today is venting into a chimney built for something else entirely.
That history is why we lead with safety on every call. Before we quote a part, we run a combustion analysis, test for carbon monoxide, check the draft at the vent connector, and look at the condition of the flue and the chimney. A furnace that lights and makes heat can still be spilling combustion gases into a basement, and in a house this old with occupants upstairs, that matters more than the ignitor does.
Many Takoma Park houses still run hot water or steam heat from a basement boiler instead, so part of the first visit is simply confirming what you have and what it is connected to.
What Takoma Park homes ask of this job.
The Takoma Park Historic District covers a large share of the older housing, and it shapes furnace work more than people expect. A 90 percent or better furnace has to vent through PVC, which means either a sidewall penetration or a run up through the roof, and on a visible street facade off Carroll Ave, Tulip Ave or Philadelphia Ave that becomes a conversation about placement before it is a conversation about equipment.
The 1880s and 1890s Victorians and four squares in Old Town Takoma were built for gravity heat, so where forced air was retrofitted in the 1960s or 1970s it runs through cramped chases and long flex duct, and the furnace fights high static pressure from the day it is installed. Along Flower Ave, Piney Branch Rd and out toward New Hampshire Ave and Takoma-Langley Crossroads the stock shifts to 1920s through 1950s brick colonials, capes and small apartment buildings, where an 80 percent furnace vents into an oversized masonry flue shared with a gas water heater.
Large frame houses divided into apartments add one more problem: a single furnace, several tenants, and nobody tracking filter changes or noticing a lockout code.
The problems that keep coming up.
- Furnaces in Old Town frame houses venting into masonry chimneys built for coal, where the flue is oversized, unlined and condensing moisture onto the vent connector.
- Oil to gas conversions where the old oil furnace footprint left the replacement equipment in an awkward spot and the return duct was never corrected.
- Cracked heat exchangers found during combustion testing on furnaces the homeowner believed were fine, because the house was still getting warm every night.
- Ignitors and flame sensors failing in the first week of November on retrofit systems near Sligo Creek that sat unused in a damp basement.
- Old electrical panels that will not support an electric furnace or a heat pump upgrade without a service change happening first.
How the appointment runs.
On an older Takoma Park house we start in the basement and work outward. That means identifying what equipment is there, checking the vent connector pitch and condition, looking up the chimney where we can, and putting a combustion analyzer on the furnace before we decide anything. We test for carbon monoxide in the room as well as in the flue.
Access is often the hard part: low headroom, a stone or brick foundation, and a mechanical area that has collected storage, laundry and a water heater over a century. If the house has been divided into apartments, we need access to the unit with the thermostat as well as to the basement, so it helps to line that up before we arrive.
If the fix involves venting or the chimney, we explain what is required and what historic district review will want to see before exterior work starts.
What decides the scope here.
The venting route is what makes furnace replacement here different from anywhere else we work. A 90 percent or better furnace vents through PVC to the outdoors, which means a new penetration through a wall, and in the Takoma Park Historic District a termination on a street-facing elevation is an appearance question before it is a mechanical one. That single fact decides where equipment can go and sometimes decides which equipment is realistic.
The second issue is what the old chimney was doing. These houses ran coal, then oil, then gas, and the masonry flue usually carries the furnace and the water heater together. Move the furnace to sidewall venting and the water heater is orphaned in a flue far too large for it, which is a draft and combustion safety problem to be solved in the same job rather than noticed later.
Combustion air is the third, because a furnace in a basement that has since been finished may no longer have the air it needs to burn. Parts are ordinary: igniters, flame sensors, pressure switches and thermostats on the truck, inducers, gas valves and control boards ordered.
When this goes wrong in Takoma Park.
November's first genuinely cold night and the January cold snap produce the two waves of no-heat calls, and these houses drop temperature quickly when heat stops, because plaster over lath with little wall insulation does not hold much. There is a second seasonal question specific to Takoma Park, though, and it is worth asking in the fall rather than in an emergency: whether this should be your last furnace.
A lot of people here intend to move off gas eventually, and the worst time to make that decision is at eleven at night in January with a dead furnace and a cold house, because the fastest available answer is always another furnace. Deciding it in October, when a fall check tells you honestly how much life the equipment has left, is how people end up with the system they actually wanted.
The fall check earns its place regardless: combustion analysis, heat exchanger inspection, draft test and a carbon monoxide check are the items that catch a chimney problem in a house with three generations of appliance history.
Working in Takoma Park.
We are based nearby in Silver Spring, at 9737 Mount Pisgah Rd in 20903, which puts most of Takoma Park inside a short drive down New Hampshire Ave or Piney Branch Rd. Yosef founded Home Comfort Air Services in 2014 after working as a service technician, and it is still family owned. Old houses reward that experience, because the right answer is often a repair and a venting correction rather than a replacement quote.
We are NATE certified, ACCA members, Carrier authorized and BBB accredited with an A+ rating, licensed in Maryland under MD70918. Emergency service runs 24 hours. Repairs are 10% off for military and seniors, and a complete system installation carries $150 off.
Common questions.
My house is in the historic district. Does that affect furnace replacement?
Inside the basement, no. The equipment itself is not a historic district question. Where it matters is venting. A high efficiency furnace needs PVC intake and exhaust run to daylight, and if that lands on a street facing wall, placement is worth discussing early. An 80 percent furnace that keeps using the existing chimney avoids the issue entirely.
The furnace works, but the basement smells odd when it runs.
That is worth a same day look. A furnace can produce heat and still spill flue gases back into the room if the draft is weak, the chimney is partly blocked, or the vent connector has rusted through. We test for carbon monoxide and measure draft directly rather than guessing from a smell. If a gas water heater shares that chimney, we check both.
Should I replace my old furnace with a heat pump instead?
Often yes, if the house can support it. Modern heat pumps hold useful capacity down into the twenties, which covers most of a Takoma Park winter, and Pepco residential rebates apply. The real limits here are electrical service and duct condition. We run the load calculation and tell you whether the house is ready.
Where can a high efficiency furnace vent in a historic district house?
Somewhere that works mechanically and does not create an appearance problem, which is the whole design question. PVC venting has limits on length and on how it terminates, including clearances from windows, doors and grade, so the options are constrained before appearance enters it. We identify the workable terminations first, then tell you which of them are likely to be a review question. The mistake is ordering equipment on the assumption that a termination will be acceptable.
If I go high efficiency, what happens to my water heater?
It gets addressed as part of the same job. Once the furnace stops using the chimney, the water heater is alone in a flue sized for two appliances, and an oversized cold flue can fail to establish draft. The usual answers are relining the chimney to suit the remaining appliance or moving the water heater to a power vented or direct vented model. We would rather price that with the furnace than leave you with a venting problem that surfaces the following winter.
Should this be my last furnace before switching to a heat pump?
It is a fair question and the answer depends on your house rather than on principle. What matters is the condition of the existing furnace, whether your electrical panel can carry a heat pump plus auxiliary heat, what the envelope does to the heat loss, and whether the outdoor unit has a workable location under the historic district. We will lay out both paths with their real constraints. What we will not do is tell you gas is finished, or tell you heat pumps do not work here, because neither is true in the general case.
