Heating Glendale Homes, from Catlin Court to 1970s Subdivisions

Glendale’s housing is older than Mesa’s, Scottsdale’s or Chandler’s. In the Census Bureau’s 2020–2024 American Community Survey, 35.4% of Glendale homes were built before 1980, and the 1970s alone account for 23.4%, more than any other decade; the 1970s and 1980s together built 46% of the homes standing today. The median home dates to 1986, which makes Glendale’s housing the second oldest of the five cities on our heating pages, after Tempe. About three in four occupied homes, 74.9%, heat with electricity, through a heat pump or electric strip heat, and 21.5% heat with utility gas. Southwest Gas lists Glendale among the communities in its Arizona tariff.

The oldest neighborhoods go back more than a century. Glendale’s National Register list runs from the Catlin Court Historic District, platted in 1914, and Floralcroft, platted in 1928, to postwar neighborhoods such as Sands Estates (1947–1966), Glendale Gardens (1955) and Sage Acres (1959). The city’s historic preservation plan notes that 23 new subdivisions were platted between 1946 and 1950 alone. Homes this age have usually been through several heating systems, and the ducts, electrical connections and drains are often older than the unit, so we check them and size the replacement to the house, not to the old unit.

Glendale winters can bite. NOAA’s nearest 1991–2020 normals station, in Youngtown just northwest of the city, averages a January low of 41.1°F, about 4 nights a year at or below freezing, and roughly 1,330 heating degree days, well above the fewer than 900 NOAA records at Phoenix Sky Harbor. On permits, Glendale’s Building Safety Q&A says a residential heater or air conditioner replacement needs no permit when a licensed contractor installs it, while installing, replacing or extending a gas pipe does. When a job includes gas piping, we’ll tell you whether a permit applies.

Honest Advice on Repairs vs. Replacement

Frequently Asked Questions — Heating Services in Glendale, AZ

Do I need a permit to replace my heater in Glendale?

Not for a residential replacement installed by a licensed contractor. Glendale’s Building Safety Q&A says you do not need a permit to replace a heater, air conditioner or water heater if a licensed contractor installs it. Installing, replacing or extending a gas pipe is different: that needs a permit, because the city checks the pipe for leaks and correct sizing. Our HVAC work is licensed under Arizona ROC 191372, and if your job includes gas piping we’ll tell you whether a permit applies.

I live in Catlin Court or another older Glendale neighborhood. Can you replace the heating?

Yes. Catlin Court was platted in 1914 and Floralcroft in 1928, and many nearby streets were built up after the war, when Glendale platted 23 new subdivisions between 1946 and 1950. Homes of that age have usually been through several heating systems, and the ducts, electrical connections and drains are often older than the unit and can be tight on space or undersized. We measure the heating load and inspect the ducts, then recommend a heat pump or furnace that fits the house.

How do I know if my furnace needs repair or replacement?

Age (15+ years), rising energy bills, frequent repairs, and uneven heating are signs. We diagnose and give honest guidance.

Do you offer emergency heating repair in Glendale?

Yes. Our phones are answered 24/7. For true emergencies we dispatch a technician between 6 AM and 7 PM. Call (623) 240-9892.

How cold does it get in Glendale, and is a heat pump enough?

Cold enough to matter. NOAA’s 1991–2020 normals for Youngtown, the nearest station with temperature normals, show an average January low of 41.1°F and about 4 nights a year at or below freezing. Most Glendale homes, 74.9% in the Census Bureau’s latest five-year survey, heat with electricity. A correctly sized heat pump handles a typical Glendale winter, with electric strip heat as backup on the coldest mornings, and we check both during a tune-up.
