Why sizing matters more here
Most furnaces in the Twin Cities are oversized. For decades installers sized a replacement by reading the old nameplate and rounding up, and the result is a furnace that heats the house in short, loud bursts, wears out its igniter and blower early, and leaves the far bedrooms cold because the air never runs long enough to reach them. A load calculation accounts for your home’s insulation, windows, orientation and air leakage, and it almost always lands lower than the old furnace. Right-sized equipment runs longer, quieter cycles and lasts longer.
Furnaces and the houses they go into
The 1950s and 1960s ramblers across Bloomington, Richfield and Edina usually have their original sheet-metal ductwork, which was designed for a different furnace and often leaks at every joint. We inspect it during the consultation and include sealing or resizing in the quote when it is needed, because a new furnace pushing air through leaky ducts wastes a good share of what you paid for. In two-story homes in Eden Prairie and Burnsville, we look at whether a two-stage or modulating furnace, or added zoning, will finally even out the upstairs.
Venting, gas and condensate
A condensing furnace exhausts through PVC and produces acidic condensate that must drain somewhere. We route the venting to terminate well above snow level, slope and support it properly, and install a condensate pump or neutralizer where the layout calls for one. Gas piping is pressure-tested, and the installation is set up for the city inspector before we leave.
Permits and rebates
Every furnace we install is permitted through the city where the house sits, and we schedule the inspection. Utility rebates for high-efficiency furnaces are common in the metro; your comfort advisor will tell you which your chosen model qualifies for and file what we are able to on your behalf.
Pairing with air conditioning or a heat pump
If your air conditioner is within a few years of the furnace’s age, replacing both at once saves on labor and lets us match the coil and blower properly. Increasingly, homeowners pair the new furnace with a cold-climate heat pump instead of a standard air conditioner, so the heat pump handles most of the heating season and the furnace takes over only on the coldest nights. We quote both ways so you can compare.
