Conroe Housing Stock

The median Conroe home dates to 2004, according to the Census ACS. That makes the typical house about 22 years old. Plenty of houses from this period still run original 1990s or early-2000s equipment, which is past its expected service life. About 21,000 households here own their home, 55.2% of the occupied total. The median home value is $283,100, and median household income is $75,245. We use both figures to adjust labor and pricing for this page.

Between 2020 and 2025, NOAA's Storm Events Database logged 10 hail days and 24 days with damaging thunderstorm winds in Montgomery County. The largest hail reported was 1.75 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. Montgomery County also had 4 tornado days in that period.

Symptoms Worth a Service Call

  • The blower won't stop running
  • The burners light, then shut off a few seconds later
  • Banging, squealing or rattling from the furnace
  • A yellow or flickering flame instead of a steady blue one
  • Cold air coming out of the vents

What Moves the Price

  • 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
  • Night, weekend or holiday rates
  • The diagnostic or service call fee
  • The furnace's age and brand, which affect parts availability

For Conroe we lowered the national figures about 9%, 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 diagnostic check
  • Replacing the part that failed
  • A test run through a full heating cycle

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