Heating Repair in Houston, TX

Heating repair in Houston gets busy fast on the first cold night. Our techs check furnaces and heat pumps for safe gas, good airflow and carbon monoxide, then give you the price in writing.

Signs your heating needs repair

  • No heat at all, or the system blows cool air
  • The furnace clicks but never lights
  • A yellow or flickering flame instead of blue
  • The heat pump runs but the air stays cool
  • Strange smells when you turn on heat for the first time
  • A carbon monoxide alarm goes off
  • The system turns on and off every few minutes
  • The thermostat shows heat on, but the house does not warm

Needed when the fan will not start or the board stops telling the furnace what to do.

Defrost board, reversing valve, capacitor or refrigerant leak.

Cracked heat exchanger$1,500–$3,500 (typical)

Good to know in Houston

Houston’s mild winters mean many homeowners only run heat a few weeks a year, so igniters and sensors sit idle and fail the first cold night. Cold snaps like the February 2021 freeze strained heat systems, and heat pumps working in freezing rain may ice up. Ask for a CO check on any gas furnace that has not run in months.

Gas furnace repair and anything involving refrigerant must be done by a TDLR-licensed air conditioning contractor. Install and repair of gas piping can also need a plumber licensed by the Texas State Board of Plumbing Examiners.

Questions about heating repair

Is it safe to run my furnace if it smells odd?

A short dusty smell on the first run is normal. A gas smell or rotten-egg smell is not. Leave the house and call your gas company right away.

Do I need a carbon monoxide detector?

Yes, one on each floor and near bedrooms. Test them in the fall before the first cold night.

Should I fix or replace an old furnace?

If it is over 15 years old or has a cracked heat exchanger, replacement is usually the better value. We show you both.

Do you fix heat pumps too?

Yes. Many Houston homes have heat pumps, and we repair both gas and electric heating.
