Why Fireside Heating & Air Co. Is Tempe’s Preferred Heating & Furnace Company
Tempe’s housing market is unlike anywhere else in the Phoenix metro. The concentration of aging student-rental properties near campus creates furnace problems you simply don’t see in Chandler or Scottsdale. We’ve replaced heat exchangers in units on Apache Boulevard that were original to the building - 50 years of thermal cycling in a climate that swings from 115°F summers to near-freezing winter nights.
Our technicians arrive in uniform, put on shoe covers without being asked, and treat your home the way they would their own mother’s. Every job carries our 90-Day Done Right Promise in writing - if it’s not right, we make it right, no paperwork, no arguing. That’s the Keystone Standard we’ve applied for over 8 years.
Most Tempe calls reach us within our standard response window, and we stock parts for Carrier, Trane, Lennox, and other major brands to complete repairs in a single visit whenever possible. We don’t subcontract. The technician who quotes your job does the work.
Our Heating & Furnace Services in Tempe
Furnace Repair
Tempe’s combination of extreme temperature swings, monsoon humidity, and caliche dust creates unique stress on furnace components. We see gas valve failures ground-level units near ASU’s perpetual construction zones, where fine dust infiltrates seals and solenoids. Our $50 Off Any Repair Over $250 offer applies to most service calls. The price we quote is the price you pay.
Furnace Replacement
When a furnace in north Tempe reaches 30, 40, or 50 years of age, replacement often makes more sense than chasing obsolete parts. We install systems from Carrier, Trane, Lennox, and other major brands, sizing properly for your ductwork and square footage. South Tempe’s 1980s-2000s homes typically accommodate modern 80% or 95% AFUE units with minimal retrofit. For the older stock near campus, we assess whether existing flex ductwork - often original and degraded from attic heat exposure - can support a new system safely.
Furnace Tune-Up
Our $89 Seasonal Tune-Up includes full combustion analysis, heat exchanger inspection, gas pressure verification, and safety control testing. In Tempe, we recommend fall service before the heating season begins, but we also see value in post-monsoon checks. The dust and humidity of July through September can corrode flame sensors and foul pressure switches. Catching these issues before the first cold snap prevents emergency calls.
Heat Exchanger Inspection & Replacement
This is where Tempe’s housing stock tells its story. Cracked heat exchangers are our most common serious finding in 85281 and 85282, where 1960s-70s furnaces have endured decades of thermal expansion and contraction. A cracked exchanger vents carbon monoxide into living spaces. We use combustion analyzers and visual borescope inspection - no guesswork. Replacement costs align with our standard Furnace Repair range of $150-$700 when the exchanger itself is serviceable; full furnace replacement becomes the recommendation when the unit is past safe repair.
Gas Valve Repair
Gas valves in Tempe fail from dust infiltration, corrosion from monsoon humidity, and simple age. We stock replacement valves for Goodman, Carrier, and other common brands, and we test gas pressure and manifold operation before declaring a repair complete. Safety caveat: gas valve work involves live fuel lines and combustion systems. This is not a homeowner repair - improper installation risks gas leaks, fire, or carbon monoxide exposure. Our technicians are state-licensed and trained to handle these components.
Ignitor Replacement
Hot surface ignitors in modern furnaces typically last 3-5 years in Tempe’s conditions, though monsoon humidity spikes can cause premature failure. We carry universal and OEM ignitors for quick replacement, getting your heat restored without a return trip.

Trusted Brands We Service in Tempe
We maintain training and parts inventory for nine major residential brands: Carrier, Trane, Lennox, Goodman, Rheem, York, Daikin, Bryant, and American Standard. For Tempe customers, this means faster turnaround and fewer return visits. We don’t have to order parts from Phoenix and make you wait. Our warehouse stocks common heat exchangers, gas valves, ignitors, and control boards for the brands most frequently installed in Tempe’s 85282, 85283, 85284, and 85285 ZIP codes. When we encounter a 1970s furnace with obsolete components, we give you straight talk: what parts might still be available, what the timeline looks like, and whether replacement is the smarter investment.
Common Heating & Furnace Problems We See in Tempe Homes
- Cracked heat exchangers in 1960s-70s student rentals. Decades of thermal cycling between Phoenix’s extreme summer attic heat and winter heating demand fatigues metal. We find this most often in north Tempe’s garden-style complexes, where original furnaces were never designed for 8+ years of service.
- Rust-through on furnace cabinets and flue pipes. Monsoon humidity and haboob dust create a corrosive film on attic equipment. South Tempe’s 1980s tract homes see this where roof vents allow moisture infiltration during driving monsoon rains.
- Gas valve failures from caliche dust. Ground-level furnaces near ASU construction zones and desert-landscaped properties ingest fine dust that fouls valve seats and solenoids. Symptoms include delayed ignition, rollout, or complete failure to fire.
- High-pressure lockouts from contaminated condenser coils. In north Tempe’s 85281 corridor, rooftop condenser coils on ASU-area rentals accumulate cottonwood seed and caliche dust so aggressively that our techs schedule coil cleaning twice per monsoon season to prevent lockouts in 115°F heat. While this is an AC issue, the same dust infiltration affects furnace combustion air intakes and pressure switches.

FAQs - Heating & Furnace in Tempe
The 1960s-70s furnaces in these properties were designed for 15-20 years of service and have endured 50+ years of thermal cycling between extreme Phoenix heat and winter heating demand. Decades of expansion and contraction fatigue the metal, and many units were maintained minimally by absentee landlords. Last August, during ASU move-in week, we responded to a 1970s garden-style complex on Apache Boulevard in 85281 where the furnace heat exchanger had cracked from decades of thermal stress, venting carbon monoxide into a unit leased to four students. We replaced the 40-year-old gas valve and heat exchanger with a Goodman 80% AFUE system, installing a new intake vent to meet modern safety codes. If you own or manage rental property in 85281 or 85282, annual heat exchanger inspection is not optional - it’s a liability issue. Call (866) 561-3358 to schedule.
Some parts remain available through aftermarket suppliers, but many critical components - original gas valves, heat exchangers, and control boards - are obsolete. We research availability before recommending replacement, and we won’t charge you to chase a part that doesn’t exist. When replacement is necessary, we explain why and show you the written estimate. Our Free Second Opinion on Any Written Estimate offer means you can verify our recommendation. For most 1970s units in Tempe, replacement with a modern 80% or 95% AFUE furnace pays for itself in efficiency and safety within a few years.
Our seasonal tune-up is $89 throughout Tempe, including the ASU area in 85281 and 85282. The service includes combustion analysis, heat exchanger inspection, gas pressure verification, and safety control testing. For rental properties near campus, we recommend fall service before tenant move-in and post-monsoon checks in October. Call (866) 561-3358 to book - estimates are free if we find repairs needed.
Replacement is usually the better investment for furnaces over 25 years old, especially in student rentals where reliability affects tenant retention and liability exposure. Retrofit repairs on obsolete equipment often fail within a season, costing you twice. We give straight talk about repair versus replace, with written estimates for both options. Our 90-Day Done Right Promise applies to either path. For landlords with multiple Tempe properties, we can schedule batch inspections and coordinate replacement during summer turnover.
Yes. Haboob dust settles on attic equipment, corroding flame sensors and fouling pressure switches. The July-September humidity spikes also rust flue pipes and cabinet components. We see a predictable wave of no-heat calls in October, when homeowners first switch on furnaces that sat idle through monsoon season. A $89 fall tune-up catches these issues before they become emergency calls. For properties near construction zones or with minimal landscaping, dust infiltration is worse - consider more frequent filter changes and annual professional inspection.
