Prices below are general ranges for this kind of work, not a FortHouse quote. Your exact number is written and confirmed on-site, free, before anything starts.
Repair, replacement, and maintenance for air conditioners and heat pumps.
4 services
We carry the parts that actually break — capacitors, contactors, fan motors, thermostats — on every truck. You get the fault, the fix, and the price before we start turning wrenches.
Most oversized systems get that way because someone matched the tonnage of the unit being replaced. We measure the house instead: square footage, insulation, window orientation, duct leakage.
A mini-split puts the capacity exactly where you need it. Ideal for the room that has always run eight degrees hotter than the rest of the house — a common call in the older housing stock around Plainfield and Bolingbrook.
A dirty condenser coil can cost you a quarter of your capacity. Annual service catches the slow failures — weak capacitors, low charge, restricted airflow — while they are still cheap.
Furnaces, heat pumps, and the safety checks that come with combustion.
4 services
Ignitors, flame sensors, pressure switches, and inducer motors cause most no-heat calls. We stock all four. Every visit includes a combustion safety check at no extra charge.
A furnace replacement is only as good as everything around it. We size the flue, verify the gas supply, and check that your ductwork can actually move the air the new unit produces.
Most heat pump repair calls turn out to be a stuck reversing valve, a failed defrost board, or a low charge — all diagnosable same visit. For new installs, modern cold-climate heat pumps hold capacity well below freezing; we'll show you the operating-cost math against your current gas bill before you commit.
A cracked heat exchanger is the one HVAC failure that can hurt somebody. We inspect it every visit and document what we find.
Ductwork, filtration, and controls — the parts of the system nobody sells you.
3 services
We pressure-test the duct system, find the leaks, and seal them. It is frequently the cheapest efficiency upgrade available to a house.
Whole-home solutions that work at the equipment instead of one room at a time. We start by measuring what is actually in your air.
A smart thermostat wired wrong is just an expensive dial. We configure staging, fan behavior, and heat-pump lockouts to match your equipment.
Worth saying plainly
A twelve-year-old system with a bad capacitor is a small repair, not a replacement conversation. We will tell you when a new system genuinely pencils out and when it does not, and we will show you the math either way. Long-term relationships are the whole business model — that only works if we are straight with you the first time.
