A furnace installed correctly is quiet, efficient, and safe for two decades. Installed carelessly, it's a carbon monoxide risk. We do it right and put it on permit.
Furnace replacement is a safety installation, not just an equipment swap. Venting, gas pressure, combustion air, and return airflow all have to be right — and in North Texas, where furnaces often share a closet or attic space with the air handler, there's little room for shortcuts.
Absolute Comfort Mechanical installs gas and electric heating systems throughout the Dallas–Fort Worth metroplex, pulls the mechanical permit, and gets the work inspected so it's documented for your insurance and your future home sale.
An 80% AFUE furnace sends 20% of the fuel's heat out the flue; a 96% condensing furnace keeps nearly all of it. In Minnesota that difference pays for itself quickly. In DFW, where heating season is short, the math is closer.
We look at your actual gas usage, your existing venting, and how long you plan to stay in the home. Sometimes a 96% condensing furnace with a variable-speed blower is clearly worth it — especially since that blower also improves summer comfort and filtration. Sometimes a well-installed 80% unit is the sensible choice. We'll say which and why.
Your furnace's blower moves the air in summer too. Upgrading from a single-speed to a variable-speed ECM blower means quieter operation, gentler airflow, better filtration, and noticeably better humidity control during the eight months you're cooling.
This is the upgrade homeowners thank us for most, because they feel it every day rather than only in January.
An 80% single-stage furnace is the entry point; a 96% condensing furnace with a variable-speed blower costs meaningfully more but delivers lower bills and better year-round comfort. Venting changes and gas line work affect the total. You get a fixed written quote after an in-home assessment.
Most replacements take one day. Converting to a high-efficiency condensing furnace can add time because it needs new PVC venting and a condensate drain.
Yes, always. Gas appliance replacement requires a mechanical permit in DFW municipalities, and permitted work protects your manufacturer warranty, your insurance coverage, and your home's resale documentation.
Often yes — but the new blower and coil have to be compatible with your existing outdoor unit. We check the match before quoting, and we'll tell you if the pairing would hurt your cooling performance.
If you already have gas service, a gas furnace usually costs less to run during a cold snap. If you don't, a heat pump with electric backup is typically the better investment in North Texas, since it also handles your cooling.
With annual service, 15–20 years is realistic in this climate because our heating season is short. Skipping maintenance is what shortens that — dirty burners and restricted airflow stress the heat exchanger.
