What Types of Furnaces Do We Repair?
Day & Night repairs gas furnaces, electric furnaces, and heat pump systems across the Valley of the Sun. Each type uses a different fuel source and requires a specific diagnostic approach, which our licensed technicians handle safely and to local code.
Gas Furnace Repair
Gas furnaces use a burner powered by natural gas or propane to produce heat. Most gas system repair calls involve ignition problems, gas valve issues, flame sensor failures, or exhaust venting concerns. Our technicians address each of these safely.
Electric Furnace Repair
Electric furnaces use electric heating elements and no combustion. Common repairs include failed heating elements, faulty sequencers, blower motor issues, and control board failures. Our team tests each component before recommending a fix.
Heat Pump Repair
Heat pumps handle both cooling and heating by transferring heat between indoor and outdoor units. When heat pump heating fails, the issue is often with the reversing valve, defrost cycle, or refrigerant charge. Our heat pump repair team addresses these situations across the Valley.

Should You Repair or Replace Your Furnace?
Repair is the right choice when the furnace is under 10 years old, one part has failed, and repair cost stays under 50% of a new system. Replacement is the right choice when the unit is over 15 years old, has needed multiple repairs recently, or its heating output has dropped noticeably.
The table below breaks down the decision by the factors that matter most:
| Factor | Repair Makes Sense | Replacement Makes Sense |
|---|---|---|
| Age of furnace | Under 10 years | Over 15 years |
| Repair frequency | First or rare repair | Multiple repairs in past 2 years |
| Repair cost vs new system | Under 30% of new system cost | 50% or more of new system cost |
| Heating performance | Steady, even heating | Uneven, weak, or intermittent |
| Energy bills | Normal for the season | Rising without a usage change |
| Available replacement parts | Parts easy to source | Parts obsolete or hard to find |
When replacement becomes the better path, our furnace installation team walks you through system options that match your home and budget.

On-Site Diagnostic Inspection
Our licensed technician evaluates every accessible part of your heating system before making any recommendation. We find the real cause instead of guessing. We fix the actual problem, not the symptom.
Written Repair Estimate
You receive a full breakdown of the cause, the fix, and the exact cost before any work begins. No hidden fees or surprises later. You can approve the repair with complete confidence in the number in front of you.
Repair Completed On-Site
In most cases, the fix is done during the same visit, because our service trucks are stocked with the parts that fail most on Valley furnaces. That means we restore your heat fast. You don’t need to wait days for a second trip or an ordered part.
Full System Testing
After the repair, our technician tests the system end to end. We verify airflow, ignition, thermostat response, and the safety controls. We confirm the furnace heats correctly and runs safely before we consider the job finished and pack up.
Walkthrough and Next Steps
Before leaving, our technician explains exactly what was done and shares the warranty details. We also give you tips on how to take care of your furnace.
For homeowners who want to prevent repair calls altogether, our heating maintenance plans keep systems tuned year-round.

Frequently Asked Questions
How quickly can Day & Night respond to a furnace repair call in the Valley?
Same-day service is available across most of the Phoenix metro area, including Scottsdale, Mesa, Gilbert, Tempe, and Glendale. Emergency calls get priority dispatch and are handled before routine appointments.
Do you repair furnaces installed by other companies?
Yes. Our licensed technicians repair furnaces regardless of who originally installed the equipment. Manufacturer coverage may still apply if the unit is within its warranty period. Our team can help you confirm that during the visit.
Should I get a second opinion before agreeing to a large furnace repair?
Yes, especially when the repair is quoted at 50% or more of a new system’s cost. Day & Night offers free second opinions on major HVAC repairs, so Valley homeowners can move forward with confidence.
Can furnace problems affect indoor air quality?
Yes. A malfunctioning furnace can circulate dust, allergens, or combustion byproducts through your home. If you notice unusual smells or increased dust after the heat kicks on, consider an indoor air quality check along with the furnace repair.
What should I do if my furnace stops working suddenly?
Turn the system off at the thermostat to avoid additional strain on damaged parts. Check that the circuit breaker hasn’t tripped and the thermostat is set to heat. If the system still does not respond, call Day & Night for professional diagnostics.
Can furnace maintenance reduce the chance of a repair call?
Yes. Annual professional maintenance catches worn parts before they fail during peak heating season. Our heating maintenance plans include full system inspections, cleaning, and safety checks, all of which lower the risk of unexpected breakdowns.
