Houston Weather and HVAC Load

In a normal year, Houston racks up 1,222 heating and 3,279 cooling degree days (NOAA 1991-2020 normals). Cooling carries most of the load. Heating equipment gets light use, so a furnace here often outlasts the AC it's paired with. Count on roughly 5 nights below 32°F and 109 afternoons past 90°F in a typical year.

Houston Housing Stock

Half the homes in Houston were built before 1981 (Census ACS median), so the typical house is about 45 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. About 385,000 households here own their home, 42% of the occupied total. The median home value is $253,400, and median household income is $62,894. We use both figures to adjust labor and pricing for this page.

Between 2020 and 2025, NOAA's Storm Events Database logged 28 hail days and 44 days with damaging thunderstorm winds in Harris County. The largest hail reported was 2 inches across. Hail flattens the thin aluminum fins on condenser coils and cuts airflow. After a big storm, take a look at the outdoor unit; homeowners insurance often covers the damage. Harris County also had 9 tornado days in that period.

Symptoms Worth a Service Call

  • The thermostat calls for heat and nothing happens
  • A yellow or flickering flame instead of a steady blue one
  • The burners light, then shut off a few seconds later
  • Cold air coming out of the vents
  • The blower won't stop running

What Moves the Price

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

For Houston we lowered the national figures about 15%, based on local income, home values and climate-based equipment sizing. Get at least three written quotes; real bids can land outside this range.

What the Quote Should Cover

  • A safety and combustion check
  • A test run through a full heating cycle
  • Replacing the part that failed
  • A diagnostic check

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.
  • If the furnace is past 15, ask the tech to price both a repair and a replacement.
  • Ask whether the diagnostic fee comes off the repair bill.
