Conroe Weather and HVAC Load
NOAA's 1991-2020 climate normals put Conroe at 1,440 heating degree days and 3,172 cooling degree days per year. Cooling carries most of the load, which is why compressors and condenser fan motors wear out faster here than in northern cities. Count on roughly 16 nights below 32°F and 105 afternoons past 90°F in a typical year. On the cooling side, a 2,000 sq ft house here usually needs around 3.5 tons. A tight, well-insulated house may get by with half a ton less.

| Nights at or below 32°F | 16 |

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.

Texas Permits, Efficiency Rules and Rebates
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). Equipment replacements in Conroe generally need a mechanical permit, and a reputable contractor will pull it for you. Ask for their Texas license or registration number and a certificate of insurance with the quote. The federal 25C tax credit ended for equipment installed after December 31, 2025, so incentives now come mostly from utilities and state programs. Check your electric and gas utility's rebate page before you pick equipment.
Before You Hire
- Multi-zone systems cost more per room, but they run off a single outdoor unit.
- If winter nights regularly drop below 10°F, pay for a cold-climate model.
- Most mini-splits qualify for utility heat pump rebates, so check before you buy.
