Tempe’s first freeze tends to come early in December, so a heating check belongs on the fall list. A Delta technician inspects and tests your heating system, checks the gas connections, lubricates moving parts as needed and replaces the air filter when you provide one. Every visit is documented, so you keep a dated maintenance record for your system. Call (623) 240-9892 to schedule your Tempe heating maintenance visit.
Heating Maintenance in Tempe: A First Freeze by Early December
Tempe gets cold early. In NOAA’s 1991–2020 normals for the Tempe ASU station, half of all years have had a freeze by December 5, the earliest of the five Phoenix-area stations on our heating pages, and a freeze occurs in nearly every year. The normal December low is 37.7°F, and about 52 nights a year reach 40°F or below.
Those are the nights a heat pump works hardest. The U.S. Department of Energy’s Building America guidance notes that the heating efficiency of a standard air-source heat pump drops when outside temperatures fall below about 35°F, which is why a backup heat source is often needed, and that heat pumps have a built-in defrost cycle to keep the outdoor coil from icing up. A defrost cycle on a cold morning is the system doing its job; if the outdoor unit stays iced over, call us.
Tempe writes heating into city code. Its Rental Housing Code, which covers single-family rentals as well as apartments, says every rental housing unit should contain safe heating and cooling facilities that are properly installed and maintained in sound condition. For low-income homeowners with a failing system, Tempe’s Housing Services runs a repair and replacement program that covers heating as well as cooling; ask the city whether its waitlist is open.

HEATING MAINTENANCE
Find Problems Before the First Cold Night
A Tempe furnace or heat pump can go months without running in heating mode. Dust settles, parts age, and nobody notices until the thermostat calls for heat. A maintenance visit in the fall is when a worn part or a loose connection gets found, while there is still time to fix it.

WHY HEATING MAINTENANCE MATTERS IN Tempe
What a Desert Winter Asks of Your System
- Months of sitting idle between heating seasons
- Dust that collects in filters over the summer
- Cold mornings after warm afternoons, so the system cycles on and off
- Heat pumps that have already worked through a full summer of cooling
- Gas appliances that need their connections and venting checked
What a Visit Can Catch
During a maintenance visit we look for:
- Worn or failing parts
- Loose or faulty electrical connections
- Airflow problems and clogged filters
- Cracks in the heat exchanger that we can see
- Venting or gas connection problems

BENEFITS OF REGULAR HEATING MAINTENANCE
for Tempe Furnaces and Heat Pumps
Parts and Connections
Find worn parts early
Our technicians can identify worn-out parts, faulty connections or airflow issues early, while there is still time to fix them.
Safety Checks
Gas connections, venting and heat exchanger
Our heating maintenance visit includes safety checks of the gas connections, venting and visible heat exchanger surfaces, and we show you what we find.
A Heating Cycle Test
Checked before you need it
We run the system through a heating cycle and test the safety controls, so the first cold night isn’t the first time it has run since spring.
A Fresh Filter
When you provide one
We replace the air filter when you provide one. ENERGY STAR’s advice is to check the filter every month, especially in heavy-use months, and to change it at least every 3 months.
Keep a Maintenance Record
Documented visits
Every visit is documented, so you keep a dated maintenance record for your system.

We tell you what we found and what it means before you decide anything.
WHEN TO SCHEDULE HEATING MAINTENANCE
for Your Tempe Heating System
Fall Visit (Recommended)
Schedule your visit in October or November, before the first cold nights. ENERGY STAR’s advice is to check the heating system in the fall, because contractors get busy once winter comes. This timing allows you to:
- Fix what we find before you need the heat
- Start the season with a checked system
- Book before the winter rush
- Put in a fresh filter at the start of the season
Need a Repair or a New System?
If the visit turns up a problem, we explain your repair options and put the price in writing before any work begins. See heating repair in Tempe for what we fix, or heating installation in Tempe if it’s time for a new furnace or heat pump.
Heat Pumps Work Year-Round
A heat pump heats in winter and cools in summer, so it never gets an off-season. A fall visit checks it for heating; for the cooling side, see AC maintenance in Tempe.
SIGNS YOUR HEATING NEEDS
Attention Now
Don’t wait for a maintenance visit if you notice:
- No heat, or air that never gets warm
- A burning smell that doesn’t clear after the first few minutes of the season’s first run
- The system turning on and off more than usual
- New banging, squealing or grinding noises
- Ice on a heat pump’s outdoor unit that doesn’t clear
- A yellow furnace flame instead of blue; Southwest Gas tells its customers to call the company immediately
- A gas smell: leave the house, then call 911 and your gas utility

Frequently Asked Questions — Heating Maintenance Tempe
Does the City of Tempe recommend yearly heating service?
Yes. Tempe Fire Medical Rescue’s carbon monoxide guidance says to have your heating system, water heater and any other gas or oil burning appliances serviced by a qualified technician every year. Our visit inspects the heat exchanger, venting and gas connections; it does not include a carbon monoxide test.
What does Delta’s heating maintenance visit include?
A Delta technician inspects and tests your gas furnace or heat pump: heat exchanger, gas connections, venting, safety controls, electrical connections, blower and airflow. We lubricate moving parts as needed and replace the air filter when you provide one. It doesn’t include burner cleaning or adjustment, blower compartment cleaning, a carbon monoxide test or a gas pressure check.
My heat pump’s outdoor unit frosts over on cold Tempe mornings. Is it broken?
Not necessarily. A heat pump defrosts its outdoor coil on cold mornings, and NOAA’s normals for the Tempe ASU station show about 17 nights at 40°F or below in December and 16 in January. If the ice doesn’t clear, or the house won’t warm up, call us for a repair.
When does Tempe usually get its first freeze?
Early December in a typical year, and sometimes sooner. In NOAA’s 1991–2020 normals for the Tempe ASU station, half of all years have had a 36°F night by November 26, and in one year out of ten the first freeze has come by November 18. Book heating maintenance in October or early November.
Is Delta Home Services licensed to work in Tempe, AZ?
Yes. Delta Air Conditioning LLC holds an active ROC license 191372 and serves Tempe as part of our Phoenix metro service area.
