Tempe AC Tune-Ups for Older Homes and Hot Summers
Tempe’s housing is the oldest of the five cities on our AC maintenance pages. The Census Bureau’s 2020–2024 American Community Survey puts the median home at 1984, with 41.2% built before 1980, including 24.2% in the 1970s and 11.5% in the 1960s. The city’s historic preservation directory lists postwar districts such as the Roosevelt Addition, brick National Folk Ranch homes built from 1946 to 1950, University Park (1945–1960) and Date Palm Manor (1953–1959). Homes this age have usually been through several air conditioners, and the ducts, electrical connections and drains are often older than the unit.
Summers are long. NOAA’s 1991–2020 normals for its Tempe ASU station show a July high of 105.9°F, about 107 days a year at 100°F or hotter and roughly 3,680 cooling degree days, with about 3 inches of rain in the July–September monsoon months. Nights cool off a little more on campus than at the airport, with a July low of 75.8°F at the ASU station against 84.5°F at Sky Harbor. Older equipment and ducts, plus months of near-constant run time, are why a spring tune-up pays off here: small problems like a weak capacitor or a partly blocked condensate drain get found before they stop the system.
Replacement rules are clear in Tempe. City Code Chapter 8, section 105.2, exempts replacing an air conditioner, furnace or heat pump in the same location with a unit of equal or lower BTU, cfm and amperage rating in a single-family home. A tune-up needs no permit, and if the inspection shows replacement is near, we explain whether your job fits the exemption. If a repair isn’t affordable right now, the City of Tempe runs home-repair assistance for eligible homeowners.

Frequently Asked Questions — AC Maintenance Tempe
My Tempe home was built in the 1950s or 1960s. What should an AC tune-up check?
Everything on the standard 20-point list, plus the parts that age with the house. Tempe’s postwar neighborhoods, such as the Roosevelt Addition, University Park and Date Palm Manor, have usually been through several systems, so the ducts, electrical connections and drains are often older than the unit. We look closely at the accessible ductwork, the electrical disconnect and the condensate line, and check that airflow matches the size of the system.
What does Delta's AC maintenance visit include?
It’s an inspection. Our technician checks and tests the 20 points on our checklist and replaces your air filter when you provide one. The visit takes about 30 minutes. It doesn’t include coil cleaning, lubrication or adjustments.
Do I need a permit to replace an air conditioner in Tempe?
Not for a like-for-like swap. Tempe City Code Chapter 8, section 105.2, exempts from permits the replacement of an air conditioner unit, furnace, heat pump or evaporative cooler in the same location with equal or lower BTU, cfm and amperage ratings, in a detached single-family home, duplex or townhome. A bigger unit or a new location needs a permit; we’ll tell you whether one applies to your job. A tune-up needs no permit.
Does monsoon season affect my AC in Tempe?
It adds to the load. NOAA’s 1991–2020 normals for the Tempe ASU station show about 3 inches of rain from July through September, and the storms that bring it often carry dust and debris onto the outdoor coil. Monsoon humidity also means more condensate, so a partly blocked drain line can overflow. After a big storm, rinse loose debris off the outdoor unit with the power off, and if airflow drops or water appears near the indoor unit, call us.
