Expect to pay $5,700 to $13,000 for boiler replacement in Peoria, AZ. Most homeowners end up near $9,700, depending on the equipment tier and how much of the old setup can be reused.
Peoria Weather and HVAC Load
In a normal year, Peoria racks up 1,532 heating and 3,471 cooling degree days (NOAA 1991-2020 normals). Cooling carries most of the load. Heating equipment gets light use, so a furnace here often outlasts the AC it's paired with. Count on roughly 13 nights below 32°F and 157 afternoons past 90°F in a typical year. For a 2,000 sq ft house, this climate points to a heating load somewhere near 35,000 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 | 1,532 |
|---|---|
| Cooling degree days / year | 3,471 |
| Nights at or below 32°F | 13 |
| Days above 90°F | 157 |
| Average low / high | 55.9°F / 84.5°F |
Peoria Housing Stock
Half the homes in Peoria were built before 1998 (Census ACS median), so the typical house is about 28 years old. Plenty of houses from this period still run original 1990s or early-2000s equipment, which is past its expected service life. Owners live in 75.5% of occupied homes, roughly 55,000 households. Homes here have a median value of $429,400 and households a median income of $93,403. Those two numbers drive the labor adjustment in our estimate.
NOAA storm reports for Maricopa County show 24 hail days and 79 days with damaging thunderstorm winds over the six years from 2020 to 2025. 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. In Peoria, 19.6% of residents are 65 or older. For older adults, a house with no heat in January or no AC during a heat wave is a medical risk. Mention it when you call, since many companies put those calls first.

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 Peoria 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 for a heat-loss calculation. A lot of old boilers are much bigger than the house needs.
- For a steam system, hire a contractor who works on steam regularly.
- A combi boiler frees up space and replaces your water heater.
