Electric Furnace Installation and Replacement

We install electric, gas, and oil furnaces, plus heat pumps and boilers. This page covers electric furnaces. For gas, see gas furnace installation; for oil, see our oil furnace services; and for help choosing between them, start with heating installation. If you’re switching fuels, for example from oil to electric or from an electric furnace to a heat pump, we remove the old system and handle the new connections in the same project, so you deal with one company from start to finish.

Most straight replacements take one day. We remove the old furnace, set the new one, connect power, ducts, and thermostat, test each heating stage, and clean up, so on a standard replacement you’ll usually have heat the same day. Plan on a second day if the job needs a panel upgrade, a new circuit, or duct changes, or if we’re adding a heat pump outside. We confirm the schedule after the in-home estimate, so you know exactly when we’ll arrive and how long your heat will be off.

Every electric furnace installation follows the same steps:

1. Sizing: we pick the kW from your home’s size, insulation, and how the old furnace kept up, not just the label on the old unit.
2. Electrical check: breaker, wire size, and panel capacity, before anything is ordered.
3. Removal: the old furnace comes out and leaves with us.
4. Set and connect: the new furnace is secured, then connected to power, ducts, and thermostat with sealed joints.
5. Testing: we run every heating stage and the blower and check temperatures at the registers.
6. Walkthrough: we show you the thermostat, the filter, and what to watch for, and leave the warranty paperwork.

The work area is cleaned before we leave, and the price is the one you approved at the estimate.

We install and replace electric furnaces in Philadelphia and across Bucks County, Montgomery County, Delaware County, and Chester County. Our crews work out of Willow Grove and Northeast Philadelphia, so most of the region is a short drive away. See the full list of towns on our areas we serve page.

It depends on the furnace size (kW), whether your panel and wiring can carry it, the condition of your ductwork, and whether you add a heat pump or a new thermostat. A same-size swap on good wiring sits at the low end. A larger unit that needs a new circuit or panel work costs more. We don’t quote blind over the phone: after a free in-home estimate you get one written price with nothing added later. Ask about financing and our $500 off on new systems when you book.

For most homes, sizing is straightforward. We look at square footage, insulation, windows, and how well the old furnace kept up on the coldest nights. Many homes in our area land somewhere between 10 and 20 kW, and in a typical row home or single that leaves one or two sensible choices. Too small and the house won’t keep up on cold nights. Too large and you pay for wiring and capacity you don’t need. For additions, major renovations, or new builds, a full room-by-room load calculation (Manual J) is worth doing, and we’ll tell you when it is.

Sometimes. Electric furnaces draw a lot of current, and larger units often need a dedicated 60 to 100 amp circuit. If your panel is near capacity or your service is undersized, we’ll tell you at the estimate and coordinate licensed electrical work so the furnace runs safely. Replacing a furnace with one of the same size usually reuses the existing circuit, once we’ve checked that the breaker and wire are in good shape and correctly sized.

Usually, yes. At the estimate we check duct sizes, the return, and air leaks. Small fixes like sealing joints or adding a return often make a big difference in comfort and noise. If the ducts are too small for the new furnace or for a future heat pump, we’ll show you what needs to change and price it separately, so you can decide what to do now and what can wait.

Electric furnaces on their own rarely qualify. Most utility rebates go to high-efficiency heat pumps and home weatherization, which is one more reason to price a heat pump pairing. Programs change often, so we check what’s current for your utility when we quote and point out any equipment that qualifies.

Most programmable and smart thermostats work, as long as they are set up for electric heat so the blower starts right away. With a heat pump pairing, you need a thermostat that controls auxiliary heat, so the electric strips only run when the heat pump can’t keep up. We match the thermostat to your system, handle the wiring and setup, and show you how to use it. See our thermostat services for options.
