When a furnace is genuinely done, you want the replacement sized to your house and installed properly — not whatever box fits the old footprint. We measure, we explain the options, and we give you the real operating-cost difference before you choose.
A furnace replacement is the biggest HVAC purchase most homeowners make, and it is the one most often sold badly. The usual pitch is fear: your system is old, here is a quote, sign today. We would rather show you the math.
We start with a load calculation on your actual house — square footage, insulation, windows, ductwork, and how the rooms behave in a Utah January. That determines the size. Guessing here is why so many homes have a furnace that short-cycles and never feels even.
Then we price two or three real options across efficiency levels, with the operating-cost difference over ten years. Sometimes the mid-tier unit is the smarter buy. We will say so.
Everything below is part of the quoted price. No line items appear on installation day that were not on the estimate.
We measure the house rather than matching the old unit. Oversizing is the single most common installation mistake, and it costs you comfort and money for the next twenty years.
Covers: square footage · insulation · window area · duct capacity
Full removal and responsible disposal of the existing furnace, plus any adaptation the new unit needs to fit and vent correctly.
Covers: disconnect · haul-away · plenum and vent adaptation
A new furnace pushing through undersized or leaking ducts will never perform to its rating. We check before we install, and tell you if it needs work.
Covers: static pressure test · leak inspection · return air sizing
Gas line connection, venting to code, condensate handling on high-efficiency units, and thermostat wiring — all permitted and inspected.
Covers: gas · venting · condensate · thermostat
We do not just turn it on and leave. Gas pressure, temperature rise, and airflow all get set to the manufacturer's spec so the unit actually delivers its rated efficiency.
Covers: gas pressure · temp rise · airflow · safety checks
Manufacturer warranties often require registration within a set window. We file it for you, so a claim five years out does not get denied on a technicality.
Covers: registration · paperwork · labor warranty terms

Still curious? Call — we would rather answer it now than have you guess.
Installed cost depends on the size and efficiency of the unit and what your venting and ductwork need. We quote the full installed price in writing after seeing the house — never a phone estimate, because a phone estimate is a guess.
Most straight replacements are a single day. If venting, gas line, or ductwork needs modification, it can run into a second day — and we tell you that before we start, not during.
That comes from a load calculation on your specific house, not from the size of your old unit. An oversized furnace short-cycles, wears out faster, and leaves rooms uneven. We size it properly.
Often yes, because our heating season is long. The honest answer depends on your gas usage and how long you plan to stay in the house — we run those numbers with you rather than assuming.
Placeholder — confirm financing partner and terms. This question converts, and it should be answered here.
