Fast, Reliable Heating & Furnace Across Clovis
Heating and furnace repair in Clovis typically runs $150–$700 for most repairs, with tune-ups between $80–$200, and our team can usually reach homes in the 93611, 93612, 93613, and 93619 ZIP codes within the same day. If your furnace is blowing cold air, cycling constantly, or not keeping up on these chilly San Joaquin Valley nights, call us at (844) 875-9451. We’ve worked on hundreds of systems across Clovis, from the older ranch-style homes near Old Town to the sprawling two-story tracts in northeast Clovis, and we know the specific failure patterns this valley climate creates.
Clovis sits where the valley floor begins rising toward the Sierra Nevada, and that geography matters for your furnace. The temperature swings here are brutal on HVAC equipment, scorching 105°F+ days followed by nights that dip into the 40s. Your furnace doesn’t get a break, and neither do we when you need it fixed right.
Why Redwood Heating & Air San Diego Is Clovis’s Preferred Heating & Furnace Company
Gregory Hahn founded this company and still leads every technical decision. That means when you call for furnace work in Clovis, you’re getting owner-level accountability, not a dispatcher sending whoever’s available. Our Heating & Furnace team has 13 years in the field and 428+ verified reviews averaging 4.6 stars, built one honest repair at a time.
We’ve earned particular trust in Clovis because we understand what other contractors miss: the city’s explosive growth from the mid-1990s through the 2010s created an enormous cohort of large, two-story tract homes in master-planned communities, particularly in northeast Clovis (93619), all built with builder-grade systems now hitting simultaneous end-of-life. No neighboring city has this same dense concentration of same-vintage, oversized, overworked residential furnaces all coming due at once. Fresno’s housing stock is more mixed-vintage; Clovis is a replacement-cycle hotspot, and we’ve diagnosed more cracked heat exchangers and failing blower motors in these homes than we can count.
Our response time to Clovis is typically same-day for non-emergency calls, and we carry parts for Trane, Lennox, Goodman, and Rheem systems so we’re not ordering components from Fresno while your house gets cold. Gregory Hahn holds a Master Technician designation, and that credential is on the truck, not locked in a corporate office somewhere.
Our Heating & Furnace Services in Clovis
Furnace Repair in Clovis
Most furnace repair calls we get in Clovis involve systems that have been running hard through long heating seasons in large, leaky two-story tract homes. The blower motors fail from continuous runtime. The ignitors crack from thermal stress. Gas valves get gummed up with dust from nearby agricultural fields. We diagnose the actual problem, not just the symptom that showed up first. A typical furnace repair in Clovis runs $150–$700 depending on the component and accessibility.
Furnace Replacement in Clovis
Here’s the reality for many Clovis homeowners, especially in 93619 and eastern 93611: your builder-grade furnace was probably undersized or poorly zoned for your actual square footage from day one. When we replace furnaces in these master-planned communities, we don’t just swap the box. We calculate proper load, evaluate ductwork, and often recommend zoning additions because a single thermostat trying to heat 3,500 square feet across two stories is a recipe for perpetual discomfort. We install Carrier, Trane, Lennox, and other major brands, and we’re familiar with the San Joaquin Valley Air Pollution Control District requirements that restrict equipment selection here.
Furnace Tune-Up in Clovis
A furnace tune-up in Clovis costs $80–$200 and pays for itself in efficiency and longevity. Given how hard these systems work through valley winters, we inspect heat exchangers for cracks (a safety issue you cannot ignore), clean burners fouled by agricultural dust, test gas pressure, and check blower amp draw. We recommend annual tune-ups for any system over 8 years old, and twice-yearly if you’re in one of those 2,500+ square foot two-story homes where the furnace never truly rests.
Heat Exchanger Repair & Replacement in Clovis
Heat exchanger cracks are the most serious furnace problem we encounter in Clovis, and they’re more common here than contractors from milder climates expect. The extreme thermal cycling, scorching 105°F+ days followed by furnace-demanding nights, fatigues metal over years. A cracked heat exchanger can leak carbon monoxide into your home. We responded to a call in the 93619 ZIP code where a 2003-built two-story home in a master-planned community had a single-zone builder-grade furnace that was struggling to heat the upper floor. The heat exchanger was cracked from years of thermal stress, and the blower motor was failing. We replaced it with a two-stage Carrier gas furnace with a zoning system, which balanced the temperature between floors and resolved the chronic hot-upstairs issue. If we find a crack, we will show you. No exceptions. This is not a repair you delay.
Ignitor Replacement & Gas Valve Repair
Hard water scale and fine dust from Clovis’s agricultural surroundings accelerate wear on ignition components and gas valves. These aren’t always separate calls; a failing ignitor can mask a gas valve problem, and vice versa. We test both, replace what’s actually failed, and clean what can be saved. Most ignitor replacements in Clovis fall in the lower half of our $150–$700 repair range.

Trusted Brands We Service in Clovis
We service your brand. That’s not a slogan; it’s a technical capability that matters when you live in a city where furnace downtime in January is not an option. Gregory Hahn and our technicians are factory-trained or field-experienced across nine major HVAC brands: Carrier, Trane, Lennox, Goodman, Rheem, York, Daikin, Bryant, and American Standard. We stock common parts for Trane, Lennox, Goodman, and Rheem systems on our service vehicles, which means faster turnaround for Clovis customers. We don’t tell you to wait a week because your brand is “special order.” From a single mini-split to a full commercial system, we diagnose right the first time.
Common Heating & Furnace Problems We See in Clovis Homes
- Heat exchanger cracks from extreme thermal cycling. Clovis’s pattern of scorching 105°F+ days and cool valley nights forces furnaces to cycle on and off repeatedly, fatiguing the heat exchanger metal. We find this most often in 15–20 year old systems in the 93619 and eastern 93611 ZIP codes. It’s a safety issue requiring immediate attention.
- Blower motor failures due to continuous runtime. Large, leaky two-story tract homes in northeast Clovis force furnaces to run longer to maintain temperature. The blower motor bears that load. We see premature failures in homes where the original builder-spec motor was never designed for that duty cycle.
- Gas valve and ignitor problems from agricultural dust and hard water. Fine particulate from nearby fields settles on burner assemblies and ignition components. Hard water scale affects gas valve operation. These aren’t generic “wear and tear” issues; they’re specific to the San Joaquin Valley environment.
- Single-zone temperature imbalance in two-story homes. In the large two-story homes of northeast Clovis (93619), single-zone builder systems consistently produce a scorching upper floor versus a tolerable ground floor complaint every summer — and the reverse problem in winter. Local techs know this pattern so well that many lead with a zoning damper or mini-split addition to the master suite level before even discussing full system replacement.
Pricing for Heating & Furnace in Clovis, CA
| Service | Price Range in Clovis |
|---|---|
| Furnace Repair | $150–$700 |
| Furnace Tune-Up | $80–$200 |
What moves you within these ranges? The specific component (ignitor versus gas valve versus blower motor), system accessibility, and whether we need to address underlying duct or zoning issues. A straightforward ignitor replacement in an accessible attic runs toward the lower end. A heat exchanger replacement, which we often recommend upgrading to a full furnace replacement given labor overlap, runs higher. We provide upfront pricing before any work begins, and estimates are free. Call (844) 875-9451 for an exact quote on your system.
Unlike generic furnace pages, this Clovis page explains how the city’s unique 1990s–2000s tract home boom and extreme valley temperatures create specific end-of-life patterns and zoning needs that most contractors outside the area miss. That’s not marketing language; it’s the difference between a technician who recognizes your home’s builder-grade single-zone system on sight and one who treats it like any other furnace.

FAQs — Heating & Furnace in Clovis
Extreme thermal cycling is the primary cause. Clovis’s scorching 105°F+ days followed by cool valley nights force furnaces to heat up and cool down repeatedly, fatiguing the metal. In the large two-story tract homes built during the 1990s–2000s boom, undersized or overworked systems compound the stress. We inspect heat exchangers with visual and camera methods during every tune-up and repair call. If yours is cracked, we’ll show you the image and discuss replacement options immediately. Call (844) 875-9451 for a safety inspection.
Yes. The San Joaquin Valley Air Pollution Control District (SJVAPCD) Rule 4905 mandates low-NOx furnaces throughout the region, including all Clovis ZIP codes. This restricts equipment selection to models that meet the district’s nitrogen oxide emissions standards. Contractors from coastal California markets are often unprepared for this requirement. We specify compliant equipment on every replacement and keep current with rule amendments. Call (844) 875-9451 to confirm your replacement options.
Single-zone builder-grade systems in large two-story Clovis homes were frequently undersized for actual multi-story heating loads. Heat rises, but in these homes there’s often not enough conditioned air reaching the second floor to begin with. We see this pattern constantly in 93619 and eastern 93611. Zoning additions, duct remediation, or right-sized replacement with multi-stage equipment typically resolve it. We can evaluate your specific home and recommend the most cost-effective fix. Call (844) 875-9451 for a free assessment.
Most builder-grade furnaces installed during Clovis’s 1990s–2000s construction boom are now 15–25 years old and approaching end-of-life. Replace when repair costs exceed 40% of replacement value, when the heat exchanger is cracked, or when you’re facing repeated component failures in a single season. Given the valley’s temperature extremes, running an aging furnace into failure mid-winter is a gamble. We provide honest assessments of remaining useful life. Call (844) 875-9451 for a replacement quote.
