Casas Adobes Weather and HVAC Load
In a normal year, Casas Adobes racks up 1,545 heating and 3,150 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 20 nights below 32°F and 159 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.

| Nights at or below 32°F | 20 |

Casas Adobes Housing Stock
Half the homes in Casas Adobes were built before 1986 (Census ACS median), so the typical house is about 40 years old. Plenty of houses from this period still run original 1990s or early-2000s equipment, which is past its expected service life. About 21,000 households here own their home, 66.9% of the occupied total. Homes here have a median value of $311,100 and households a median income of $81,041. Those two numbers drive the labor adjustment in our estimate.
Pima County had 26 hail days and 100 days with damaging thunderstorm winds from 2020 through 2025, according to NOAA storm records. The largest hail reported was 1.75 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. Pima County also had 6 tornado days in that period. In Casas Adobes, 24.4% 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. Expect the contractor to pull a mechanical permit for a replacement job in Casas Adobes. If a bidder suggests skipping it, move on. Also ask for a Arizona 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.
