Lewisville Weather and HVAC Load
NOAA's 1991-2020 climate normals put Lewisville at 2,437 heating degree days and 2,625 cooling degree days per year. Neither season dominates in Lewisville. That balance is a big reason heat pumps and dual-fuel systems sell well in Texas. A normal year brings 44 nights at or below freezing and 104 days over 90°F. For a 2,000 sq ft house, this climate points to a heating load somewhere near 40,000 BTU/h. Treat that as a starting number. A Manual J calculation will move it up or down based on insulation and windows.
| Heating degree days / year | 2,437 |
|---|---|
| Cooling degree days / year | 2,625 |
| Nights at or below 32°F | 44 |
| Days above 90°F | 104 |
| Average low / high | 54.7°F / 76.2°F |
Lewisville Housing Stock
Census figures put the median build year in Lewisville at 1996, so a typical house here has about 30 years on it. Plenty of houses from this period still run original 1990s or early-2000s equipment, which is past its expected service life. About 23,000 households here own their home, 46.6% of the occupied total. The median home value is $350,200, and median household income is $85,002. We use both figures to adjust labor and pricing for this page.
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.
When It Makes Sense
- Your AC needs replacing, and you'd like cheaper heat at the same time
- There's no natural gas service on your street
- Energy bills are higher than you want them to be
What Moves the Price
- Backup heat, either electric strips or a gas furnace (dual-fuel)
- Variable-speed (inverter) or single-stage compressor
- A ducted system or a ductless mini-split
- Electrical panel capacity and wiring
- Size in tons, and whether the unit is cold-climate rated
We raised the national figures about 18% for Lewisville using local income, home values and the equipment size this climate needs. Real bids can still come in outside the range, so collect three written quotes.
What the Quote Should Cover

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). Plan on a mechanical permit for most replacements in Lewisville; the contractor normally pulls it. Before you sign, ask each bidder for their 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
- Where winters get cold, ask for a model on the NEEP cold-climate list.
- A dual-fuel setup keeps your gas furnace as backup for the coldest nights.
- Make sure the installer sized the system for your heating load, not only cooling.

Heat Pump Installation Questions from Lewisville Homeowners
How much is heat pump installation in Lewisville?
Plan on $6,500 to $15,900, with most jobs near $11,700. Equipment efficiency, house size and the condition of the ducts and wiring decide where your quote falls.
When is the best time to schedule heat pump installation in Lewisville?
In spring or fall. Those are the slow months between heating and cooling season in Lewisville.
Do heat pumps work in cold weather?
Yes. Cold-climate heat pumps keep making heat well below 0°F. They lose efficiency as it gets colder, so many homes in cold regions keep backup heat.
How long does a heat pump last?
Usually 12 to 15 years. A heat pump runs year-round, so it needs maintenance twice a year rather than once.
