Keeping Glendale Air Conditioners Ahead of the Heat

The West Valley runs hot for longer. NOAA’s nearest 1991–2020 normals station to Glendale, in Youngtown just to the northwest, averages about 115 days a year at 100°F or hotter, the most of any station near the five cities on our AC maintenance pages, with a July high of 104.9°F and roughly 3,870 cooling degree days, and July nights there average 79.7°F. That is more 100-degree days than NOAA records at Phoenix Sky Harbor, about 111 a year. Monsoon season adds about 2.6 inches of rain from July through September, along with the dust that comes before the storms.

Much of Glendale’s housing is now roughly 35 to 55 years old. In the Census Bureau’s 2020–2024 American Community Survey, the 1970s and 1980s together account for 46% of Glendale homes, and 35.4% were built before 1980; the median home dates to 1986. The postwar neighborhoods on the city’s National Register list include Sands Estates, built from 1947 to 1966, Glendale Gardens (1955) and Sage Acres (1959), and Catlin Court goes back to 1914. Homes of that age have usually been through several air conditioners, and the ductwork, electrical disconnect and condensate drain are often older than the unit, so we check those too.

Glendale makes replacement simpler than most. Its Building Safety Q&A says a residential heater or air conditioner replacement needs no permit when a licensed contractor installs it. A tune-up never needs one. If the inspection shows your system is failing, we explain the repair and replacement options, with the price in writing, before any work starts. If a repair isn’t affordable right now, the City of Glendale runs home-repair assistance for eligible homeowners.

Frequently Asked Questions — AC Maintenance Glendale

Glendale sees about 115 days a year at 100°F or more. When should I book a tune-up?

In spring, before the long run starts. NOAA’s 1991–2020 normals for Youngtown, the nearest station to Glendale with temperature normals, average about 115 days a year at 100°F or hotter and a July high of 104.9°F. A tune-up in March, April or May lets us inspect the coils, test the electrical parts and check the refrigerant pressures while there is still time to fix a weak part, instead of finding it on the first 110°F afternoon.

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 my air conditioner in Glendale?

Not if a licensed contractor installs it. Glendale’s Building Safety Q&A says you do not need a permit to replace a heater, air conditioner or water heater in a residence when a licensed contractor does the work, while installing, replacing or extending a gas pipe does need one. Our HVAC work is licensed under Arizona ROC 191372. A tune-up needs no permit at all.

I live in Sands Estates, Glendale Gardens or another postwar Glendale neighborhood. What does the tune-up focus on?

The standard 20 points, plus the parts that age with the house. Glendale’s National Register list dates Sands Estates to 1947–1966 and shows Glendale Gardens platted in 1955 and Sage Acres in 1959, so homes there have usually been through several air conditioners. The ducts, electrical disconnect and condensate drain are often older than the unit, and we check them along with the coils, refrigerant charge and electrical parts.

Is Delta Home Services licensed to work in Glendale, AZ?

Yes. Delta Air Conditioning LLC holds an active ROC license 191372 and serves Glendale as part of our Phoenix metro service area.
