Furnace Installation in McKinney, TX
SmartWay installs furnaces and air handlers in McKinney and 13 nearby cities under Texas air conditioning license TACLA00108954C. Founded in 2018, with our shop on N McDonald St in McKinney.
Quoted at your home before any work starts. Texas license TACLA00108954C. Open 7 days, 7am to 7pm.
An attic furnace in a split system shares its blower and ductwork with the air conditioner, and the evaporator coil sits on the furnace cabinet. A new furnace has to be sized to the house and matched to that coil and the existing ducts.
A technician comes out from our shop on N McDonald St in McKinney to look at the house and the existing equipment. Installation is quoted at your home, and you get the price before any work starts.
Common furnace install problems
New furnace shuts off on the high limit
The furnace may be too large for the house, or restricted airflow may be tripping the high limit switch. The fix is checking temperature rise and static pressure, then opening up the return or correcting the size.
Back rooms stay cold after the new install
Duct runs in the attic may be undersized, crushed or disconnected at the boot or plenum. The technician checks each run and repairs, reseals or resizes the ducts that are short on air.
Furnace is loud when the blower comes on
A return that is too small or a blower speed set too high pushes air through the ducts under high static pressure. Adding return air or setting the correct blower speed quiets it down.
Burning smell the first time it runs
A light dusty or oily smell for the first hour or two of heating is normal on a new furnace as the coating on the heat exchanger burns off. A smell that lasts longer than that, gets stronger, or smells like hot plastic or electrical wiring is not: turn the furnace off at the thermostat and call us. If you smell gas at any point, leave the house and call your gas utility or 911 from outside. Do not open the furnace or adjust anything yourself.
Water on the floor around the new furnace
A high-efficiency furnace makes condensate that has to drain through a trap and a line or pump. A missing trap, a line with no slope or a failed pump lets water back up and spill.
New furnace lights, then drops out
The flame sensor is not proving flame. On a new install, check for reversed polarity, a poor ground or gas pressure that was never set. Each one is checked with a meter or manometer.
Reasons for a furnace install
- Adding a room onto the house: the old furnace may be too small to heat the new space
- Finishing an attic or converting a garage: the new square footage has to go into the sizing
- New AC going in with an old furnace: the blower and coil need to match the new condenser
- Moving from an 80 percent to a 90 percent furnace: the install adds PVC vent pipe to the outside and a condensate drain
- Hot plastic or electrical smell from the furnace or vents: turn it off and call, do not wait it out
How an install goes
- The technician looks at the attic or closet, the ductwork, the gas line and the flue, and sizes the furnace to the house.
- If you want a repair price on the old furnace first, that is the $65 heating diagnostic, waived if you go ahead with the repair.
- On install day the furnace goes in, the gas line, vent pipe and condensate drain are run to it, and the plenum is sealed to your coil and ducts.
- A correct install ends with a test run that checks gas pressure and confirms the temperature rise is within the range on the furnace label.

Common questions
Does it cost more to put a furnace in a new spot?
Yes, a new location usually costs more than setting a furnace where one already sits. A new spot needs a gas line, a vent path, a condensate drain and new duct connections run to it. We quote the install at your home after looking at the route for each one.
How fast can you put in a new furnace?
The first visit to look at the house can often be same day. The install is scheduled once you have the price and the furnace is on hand. A furnace for an addition or finished attic takes longer than one set in an existing spot, because the gas, venting and ducts are run new.
What size furnace do I need?
A correct install starts with sizing the furnace for the house, not copying the size of the old furnace. For an addition or finished attic, the new square footage goes into that sizing. The technician also checks that the ducts can carry the added airflow to the new rooms.
Should I get an 80 percent or a 90 percent furnace?
It depends on where the furnace sits and how the venting can run. An 80 percent furnace vents through a metal flue and costs less to install. A 90 percent or higher furnace burns less gas but needs PVC pipe to the outside and a condensate drain, which can be harder to route from an attic.
Will my old thermostat work with a new furnace?
In most cases, yes, with a single-stage furnace. A two-stage or variable-speed furnace runs best with a thermostat that can control both stages.
