Galveston Housing Stock

Half the homes in Galveston were built before 1973 (Census ACS median), so the typical house is about 53 years old. A lot of these homes are on their second or third system by now. The ductwork is usually original, and leaky joints are common. Owners live in 46.7% of occupied homes, roughly 11,000 households.

Galveston County had 7 hail days and 17 days with damaging thunderstorm winds from 2020 through 2025, according to NOAA storm records. The largest hail reported was 2.75 inches across. Storms here are more likely to cause power surges than coil damage, so a surge protector on the outdoor unit is worth the small cost. Galveston County also had 4 tornado days in that period. In Galveston, 20.1% of residents are 65 or older. For older adults, a house with no heat in January or no AC during a heat wave is a medical risk. Mention it when you call, since many companies put those calls first.

Symptoms Worth a Service Call

  • The blower won't stop running
  • Cold air coming out of the vents
  • The thermostat calls for heat and nothing happens
  • The burners light, then shut off a few seconds later
  • Banging, squealing or rattling from the furnace

What Moves the Price

  • The furnace's age and brand, which affect parts availability
  • The diagnostic or service call fee
  • Night, weekend or holiday rates
  • Which part failed: a flame sensor costs far less than a control board or blower motor
  • Whether the part is still under the manufacturer warranty

Texas Licensing and Efficiency Rules

Texas is in the DOE's Southeast region, where new split central air conditioners need at least 14.3 SEER2 (13.8 SEER2 for systems of 45,000 BTU/h and up). Most repairs don't need a permit. Anyone who opens the refrigerant circuit does need EPA Section 608 certification, and in Texas the company should carry a state license or registration. Ask for both.

Before You Hire

  • Check the filter, the thermostat batteries and the breaker first. Those three cause a surprising number of no-heat calls.
  • Have the model and serial number from the furnace label handy. Parts get ordered faster.
  • Ask whether the diagnostic fee comes off the repair bill.
