That balance is a big reason heat pumps and dual-fuel systems sell well in Texas. A normal year brings 38 nights at or below freezing and 95 days over 90°F. 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.

Denton Housing Stock
Census figures put the median build year in Denton at 1995, so a typical house here has about 31 years on it. Plenty of houses from this period still run original 1990s or early-2000s equipment, which is past its expected service life. Denton has roughly 27,000 owner-occupied homes, or 49.2% of households. Homes here have a median value of $325,700 and households a median income of $73,719. Those two numbers drive the labor adjustment in our estimate.
Denton County had 53 hail days and 31 days with damaging thunderstorm winds from 2020 through 2025, according to NOAA storm records. The largest hail reported was 5.9 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. Denton 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). Expect the contractor to pull a mechanical permit for a replacement job in Denton. If a bidder suggests skipping it, move on. Also ask for a Texas license or registration number and proof of insurance. 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
- If winter nights regularly drop below 10°F, pay for a cold-climate model.
- Rinse the indoor filters once a month during heavy use.
- Most mini-splits qualify for utility heat pump rebates, so check before you buy.
