Heating a Mesa Home, from Evergreen to Eastmark
Most Mesa homes heat with electricity. The Census Bureau’s 2020–2024 American Community Survey counts 76.5% of the city’s occupied homes heating with electricity and 20.8% with utility gas, so a heating call here is more often a heat pump or electric strip heat than a gas furnace. The same survey puts the median Mesa home at 1989, with 29% built before 1980 and 43% built in the 1970s and 1980s alone.
Age varies block by block. In the Evergreen Historic District, the city records houses going up in the North Evergreen subdivision from 1910 to 1914, and most homes in the Temple Historic District were built between 1927 and 1933, with ranch homes filling in after the war. At the other end of town, Eastmark is a 3,200-acre community between Ellsworth and Signal Butte Roads whose plan the City Council approved in 2008. Homes this age have usually been through several heating and cooling systems, and the ducts, electrical connections and drains are often older than the unit, so we check them and the equipment location before recommending a replacement.
Mesa has two gas utilities. The City of Mesa’s own gas system serves over 82,000 homes and businesses across 95 square miles of Mesa, and Southwest Gas lists Mesa among the communities in its Arizona tariff, so your bill tells you which one serves your address. Nights do get cold: NOAA’s 1991–2020 normals for the East Mesa station show an average January low of 41°F, about 11 nights a year at or below freezing, and roughly 1,250 heating degree days. For permits, Mesa Development Services does not require one to replace an air conditioning unit with one that uses the same or less electricity, but changing the electrical connections needs a construction permit. We confirm what applies to your furnace or heat pump before any work starts.

Frequently Asked Questions — Heating Services in Mesa, AZ
Is my Mesa home’s gas from the City of Mesa or Southwest Gas?
It depends on your address. The City of Mesa runs its own natural gas utility, which serves over 82,000 homes and businesses across 95 square miles of Mesa, and Southwest Gas also lists Mesa among the Arizona communities it serves. Your gas bill shows which one you have, and that is the utility to call for a gas emergency or a meter question. If you smell gas, the city’s advice is to leave the area and call 9-1-1 and the gas emergency line. Our technicians service gas furnaces on either system.
Do I need a permit to replace my heat pump or furnace in Mesa?
Sometimes. Mesa Development Services says you do not need a permit to replace an air conditioning unit if the new one uses the same or less electricity, but changing the electrical connections requires a construction permit. The city’s FAQ does not address gas furnaces separately, so we confirm the requirement for your system before we start. We’ll tell you whether a permit applies.
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 Mesa?
Yes. Our phones are answered 24/7. For true emergencies we dispatch a technician between 6 AM and 7 PM. Call (623) 240-9892.
My house is in one of Mesa’s historic districts. Can you replace the heating?
Yes. Mesa has eight locally designated historic districts, including Evergreen, where houses date to 1910–1914, and Temple, built mostly between 1927 and 1933. Homes this age have usually been through several heating and cooling systems, and the ducts, electrical connections and drains are often older than the unit. The equipment can sit in a closet, the attic or on the roof. We measure the home’s heating load and check the ductwork before sizing a new heat pump or furnace, rather than simply matching the old unit.
