HVAC Service in Texas

A homeowner deciding whether a heating repair can wait is really asking how much the furnace has to prove before it fails. Homes in Texas run heat about five months a year, from November through March. For the rest of the year that furnace sits idle, and idle time hides problems rather than preventing them. An igniter that is starting to fail, a flame sensor coated with residue, a cracked heat exchanger, none of these announce themselves while the system is off. They show up on the first morning cold enough to call for real heat, when the furnace has to light and hold without warning.

Before any new unit gets specified, a contractor has to open up what's already there and look at it. The ducts run where they run, sized for whatever moved air through this house before. The electrical panel feeds what it was built to feed. Half the homes in Texas were built in 1992 or earlier (2020-2024 ACS 5-year). That figure is why a quote can't be written from the nameplate alone. Someone has to measure the return, check the breaker, see whether the line set matches what the new equipment wants. None of that shows up until the walls are open and the panel cover is off.
