A furnace repair in this county starts with the question of what the equipment has already been through. 94 severe weather events were recorded in Galveston County, Texas between 2015 and 2024. At that rate, severe weather is a standing condition for every system here, and a contractor working a furnace repair checks the heat exchanger for stress cracks, the igniter for wear, and the control board for damage that accumulated across that exposure before landing on a cause. A homeowner who gets a quote without that review may be pricing a fix for the symptom and leaving the real failure open.
Furnaces in stock this old have typically outlasted one round of replacement already, which means the unit a contractor opens is not the original equipment. Half the homes in Galveston County, Texas were built in 1990 or earlier (2020-2024 ACS 5-year). That gap between the house and what runs in it matters at the bench, not at the curb: once the blower assembly or heat exchanger is out, the repair turns on whether the part that failed is still in production for that unit's generation of equipment. A house that predates its own furnace by decades gives a contractor nothing useful about what is inside the cabinet until it is open.
The Parts of a Furnace a Contractor Checks First
The heat exchanger sits inside the furnace cabinet and is the piece a contractor goes to early when a system is producing no heat or weak heat. The burner assembly, which fires directly into the heat exchanger, gets checked alongside it. A cracked exchanger or a burner that will not light accounts for a large share of no-heat calls.
The blower motor and its fan wheel sit in the lower section of the cabinet and push conditioned air into the supply side of the house. The draft inducer motor, which pulls combustion gases out through the flue, sits near the top of the cabinet. The control board runs the timing between all of these pieces, and a fault there can mimic a failed component anywhere in the system.
The drawing shows the general layout of a furnace system, and a licensed contractor determines which parts apply and what condition they are in for the specific unit in your home.
