Furnace Installation

Heating here is a short season with sharp edges. Most winter days need only a few cycles in the morning and evening, but a few times a year an arctic front or an ice storm holds temperatures below freezing for days, and the furnace has to keep up around the clock. A good installation is built for both: comfortable and economical on the mild days, with enough capacity for the hard ones, and placed in the attic or hallway closet where it can be serviced safely.

W3 Electric Heating & A/C installs furnaces in homes across Rowlett, Rockwall, McKinney, Garland, Wylie, Forney, and the greater Dallas area. Many of our installations replace a furnace that failed or was found unsafe on a repair call, so we work to make the decision clear rather than rushed. Our license covers electrical work as well as HVAC, so the circuit, switch, and wiring a new furnace depends on are part of our job rather than a job for a second contractor.

A furnace installation is the removal of an existing gas or electric furnace and the installation of a new one, or occasionally a furnace added where there was none. The job covers the furnace and everything it connects to: the venting, the gas supply, the electrical circuit, the thermostat wiring, the condensate drain on high-efficiency models, and the connection to your ductwork and air conditioning coil.

That makes it a different decision from furnace repair, which keeps a furnace that is still worth keeping, and from a heat pump installation, which moves most or all of your heating to an outdoor unit that also cools. If you are weighing those paths, we will price them side by side.

A furnace is only as safe and efficient as what it connects to. A low quote that skips these checks is not a bargain, because they are where a poor installation usually goes wrong.

A standard furnace sends its exhaust up a metal flue that must be the right size, slope, and distance from wood framing, and a new furnace on an old, oversized, or rusted flue can draft poorly. A condensing furnace needs its own plastic vent pipes, supported properly and ending where exhaust cannot drift back into the house. Furnaces in closets also need enough air to burn cleanly. We check all of it before quoting, so the price covers what your venting actually needs.

The gas line has to deliver enough volume for the new furnace, with a proper shutoff valve and sediment trap. The furnace needs a correctly sized circuit and a service switch, and an electric furnace may need heavier wiring, a larger breaker, or panel work before it can go in. Where a permit is required, pulling it is our job, not yours. Finding these issues while quoting is far better than finding them on installation day.

In most homes with central air, the furnace blower also moves your cooling, pushing air across the AC coil that sits on top of or beside it. A new furnace whose blower cannot move enough air for that coil will cost you next summer: weaker cooling, a coil that can freeze, and a higher electric bill. We confirm the furnace, coil, and outdoor unit work together. If your air conditioner is near the end of its life too, we will say so, and pricing an AC replacement alongside the furnace can save you a second installation later.

Furnaces here often outlast air conditioners, because they work hard for only a few weeks a year. Even so, a furnace past fifteen years old with a major part failing, or one that has needed a repair every winter for several winters, is usually a poor place to keep spending. We price the repair and the replacement side by side so you can weigh them yourself, and we will tell you when the repair is the better value.

The heat exchanger is what keeps combustion gases out of the air you breathe, and once it cracks, the furnace should not run. Replacing a heat exchanger takes most of the furnace apart, and on an older unit the cost often comes close to a new furnace that has every other part fresh as well. We document what we find and give you both prices before you decide.

Rooms that never warm, a furnace that roars on and off every few minutes, or air that swings between blasting hot and cool often trace back to a furnace that was oversized from the start, or a single-stage unit in a house that would be better served by two stages. No repair changes that. If the real problem is leaking or undersized ductwork, we will recommend duct repair rather than sell you a furnace that will not fix it.
