OUR PROCESS
What goes into a furnace replacement project?
At Comfort Club, we understand that replacing a home’s furnace system is a significant investment and a critical decision for your family’s comfort and safety. Our experienced technicians follow a thorough, step-by-step process to ensure a seamless and efficient installation, tailored to your unique needs.
From First Estimate to First Heat Cycle
A furnace replacement is gas, electrical, ductwork, and code — done in one day, in your home, often in winter. Here's exactly what we do, and the order we do it in.
-
1
In-Home Assessment & Manual J Load Calculation
We measure the home — square footage, insulation, window exposure, duct geometry — and calculate the actual heat load. Furnaces fail when they're guessed at. We don't guess. You leave the visit with a written, all-in estimate and three equipment options across efficiency tiers.
-
2
Permits Pulled, Equipment Ordered
We pull the mechanical permit with your city — every time, no exceptions. Your Lennox furnace is ordered, and we lock in an install date that fits your week. No mystery on timing.
-
3
Site Prep & Old System Removal
Drop cloths and floor protection from the front door to the equipment. Gas, electrical, and thermostat are shut off and locked out. The old furnace is disconnected, hauled out, and disposed of — no driveway pile, no extra fee.
-
4
New Furnace Set, Connected, and Sealed
Unit set level on pad or platform. Plenum and duct transitions cut and mastic-sealed — not taped. New gas flex connector and shutoff. Flue venting installed to spec (PVC for condensing units, B-vent for 80% AFUE). Condensate drain routed and trapped. Line voltage and 24V control wiring landed clean. New filter rack and filter in place.
-
5
Startup, Combustion Analysis & Safety Verification
Gas pressure verified at the manifold with a manometer. Combustion analyzer reads CO and flue gases — the only way to confirm the furnace is burning clean. Temperature rise checked across the heat exchanger. Limit switch, flame sensor, and pressure switches all tested under live conditions.
-
6
Walk-Through, Photos & Warranty Registration
We walk you through the new system — filter location, thermostat operation, what to listen for, what to never ignore. Before-and-after photos go in your file. Manufacturer warranty registered the same day, on time, so coverage holds.
-
7
City Inspection & 30-Day Quality Check
We meet the city inspector at your home — you don't have to be there. Thirty days in, we call to confirm everything's running the way it should. If it isn't, we come back. That's the whole standard.
Not sure if you should replace vs repair?
Let our experts help you! We'll schedule an in-home estimate. We typically offer same-week install for most DFW homes.

THE COMPLETE GUIDE
Everything Dallas homeowners should know about air duct cleaning
Every time your HVAC runs, air cycles through your home — picking up dust, pet dander, pollen, and allergens along the way. What you and your family breathe depends on how clean that system is. 1st Class Heat & Air offers two complementary clean air services that tackle indoor air from both sides.
Service 1: Indoor Air Quality Solutions
UV purifiers, HEPA filtration upgrades, whole-house humidifiers, and Reme Halo air scrubbers. These IAQ systems sit inside your existing HVAC and continuously treat the air as it circulates — stopping allergens, mold spores, and viruses before they ever reach your family. Read about Indoor Air Quality about our Indoor Air Quality services →
Service 2: Professional Air Duct Cleaning
Truck-mounted negative-air equipment and rotary brushes physically remove pounds of dust, dander, and debris that have built up inside your duct system. Not a shop vac, not chemical masking — real source-level cleaning that makes every room measurably cleaner. See our duct cleaning process →
Why Pair Both Services?
Duct cleaning removes what’s already built up; IAQ equipment prevents new buildup and continuously purifies. Bundle both and you get the deepest-clean indoor air possible — which is exactly what most of our Plano, Frisco, and McKinney customers choose.
