Pasadena Weather and HVAC Load
NOAA's 1991-2020 climate normals put Pasadena at 1,098 heating degree days and 3,362 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. On average, Pasadena gets 4 freezing nights and 100 days above 90°F per year.
| Heating degree days / year | 1,098 |
|---|---|
| Cooling degree days / year | 3,362 |
| Nights at or below 32°F | 4 |
| Days above 90°F | 100 |
| Average low / high | 62.5°F / 79.8°F |
Pasadena Housing Stock
The median Pasadena home dates to 1976, according to the Census ACS. That makes the typical house about 50 years old. A lot of these homes are on their second or third system by now. The ductwork is usually original, and leaky joints are common. Owners live in 54.2% of occupied homes, roughly 27,000 households. Homes here have a median value of $193,600 and households a median income of $64,270. Those two numbers drive the labor adjustment in our estimate.
Between 2020 and 2025, NOAA's Storm Events Database logged 28 hail days and 44 days with damaging thunderstorm winds in Harris County. The largest hail reported was 2 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. Harris County also had 9 tornado days in that period.
When It Makes Sense
- Your AC needs replacing, and you'd like cheaper heat at the same time
- Energy bills are higher than you want them to be
- There's no natural gas service on your street
What Moves the Price
- Backup heat, either electric strips or a gas furnace (dual-fuel)
- Variable-speed (inverter) or single-stage compressor
- Size in tons, and whether the unit is cold-climate rated
- A ducted system or a ductless mini-split
- Electrical panel capacity and wiring
We raised the national figures about 8% for Pasadena 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
- Commissioning and warranty registration
- Line set, drain and electrical hookups
- Thermostat setup and backup heat settings
- A load calculation and equipment selection
- The outdoor heat pump and an indoor air handler or coil
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 Pasadena; 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 Pasadena Homeowners
How much is heat pump installation in Pasadena?
Plan on $5,900 to $14,600, with most jobs near $10,700. 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 Pasadena?
Between late fall and early spring. With 100 days over 90°F, Pasadena contractors are booked solid all summer, and off-season jobs are easier to schedule and negotiate.
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.
