Furnace Replacement in Washington, DC

When a furnace in a Northwest DC rowhouse is past 15 to 20 years old and the repairs are stacking up, replacement usually saves money. We show you the math either way.

Replacement includes removing the old unit, matching venting to the new furnace, rebuilding the plenum where needed, and testing combustion, gas pressure and airflow.

You approve one clear price that covers the furnace and the installation.

Matching the AC

If your central air coil sits on top of the furnace, we check that it matches the new furnace in size and airflow. A mismatch can cause poor cooling or a frozen coil next summer.

Signs it is time to replace

Common signs include repairs every season, rising gas bills, rooms that never warm up, rust on the heat exchanger or a furnace over 15 to 20 years old. A cracked heat exchanger is a safety issue and usually means replacement.

Choosing the right furnace

Most Northwest DC homes do well with a high efficiency furnace that vents through the side wall with PVC pipe. If your house has an old masonry chimney, we check whether a liner or a new venting route is needed. We size the furnace to the house, not just to the old unit.

Rowhouse basements

Narrow basements and tight stairwells are common here. We plan the removal and delivery route ahead of time so the old unit comes out and the new one goes in without damage to walls or stairs.

After the install

We test gas pressure, combustion, temperature rise and airflow, set the thermostat, and show you where the filter goes and how often to change it. You get the model and serial numbers for your records.
