Tempe Weather and HVAC Load
In a normal year, Tempe racks up 1,183 heating and 3,680 cooling degree days (NOAA 1991-2020 normals). Cooling carries most of the load, which is why compressors and condenser fan motors wear out faster here than in northern cities. A normal year brings 10 nights at or below freezing and 179 days over 90°F.
| Heating degree days / year | 1,183 |
|---|---|

| Nights at or below 32°F | 10 |
| Days above 90°F | 179 |

Tempe Housing Stock
Census figures put the median build year in Tempe at 1983, so a typical house here has about 43 years on it. 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 41.6% of occupied homes, roughly 32,000 households. Homes here have a median value of $421,900 and households a median income of $77,643. Those two numbers drive the labor adjustment in our estimate.
Between 2020 and 2025, NOAA's Storm Events Database logged 24 hail days and 79 days with damaging thunderstorm winds in Maricopa 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. Maricopa County also had 4 tornado days in that period.
When It Makes Sense
- There's no natural gas service on your street
- Energy bills are higher than you want them to be
- The house heats with electric baseboard, oil or propane
What Moves the Price
- A ducted system or a ductless mini-split
- Variable-speed (inverter) or single-stage compressor
- Electrical panel capacity and wiring
- Size in tons, and whether the unit is cold-climate rated
- Backup heat, either electric strips or a gas furnace (dual-fuel)

What the Quote Should Cover

- The outdoor heat pump and an indoor air handler or coil
- Commissioning and warranty registration
- Line set, drain and electrical hookups
Arizona Permits, Efficiency Rules and Rebates
Arizona is in the DOE's Southwest 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). The Southwest also sets a minimum EER2, which measures efficiency at peak heat. Equipment replacements in Tempe generally need a mechanical permit, and a reputable contractor will pull it for you. Ask for their Arizona 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
- Ask your electric utility and state energy office what heat pump rebates are open right now.
- 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.

Heat Pump Installation Questions from Tempe Homeowners
How much is heat pump installation in Tempe?
Plan on $7,200 to $17,600, with most jobs near $12,900. 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 Tempe?
Between late fall and early spring. With 179 days over 90°F, Tempe contractors are booked solid all summer, and off-season jobs are easier to schedule and negotiate.
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.
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.
