Fast, Reliable Heating & Furnace Across San Diego
Most heating calls we get in San Diego aren’t about broken central furnaces. They’re about 1940s floor furnaces that won’t light, wall heaters with discontinued gas valves, or bungalows in North Park and Mission Hills that never had ductwork to begin with. That’s the reality of heating service here, and it’s why you need a company that understands San Diego’s housing stock, not just generic furnace swaps. Crestview Heating & Air California brings nearly two decades of HVAC experience to every San Diego job, from emergency heat exchanger repairs in Ocean Beach to full ductless retrofits in La Mesa. We’re owner-managed, not outsourced. Call (844) 560-6978 for a free estimate.
Why Crestview Heating & Air California Is San Diego’s Preferred Heating & Furnace Company
San Diego homeowners don’t want a dispatcher in another county deciding which technician shows up. Owner Marcus Feldman serves as our Service Manager, meaning ownership-level accountability is built into daily operations, not just the sales pitch. When you call Crestview, you’re talking to a team where the owner still manages jobs in the field.
That structure shows in our numbers. We’ve earned a 4.8-star average across 250+ customer reviews, and we service nine major HVAC brands: Carrier, Trane, Lennox, Goodman, Rheem, York, Daikin, Bryant, and American Standard. Your system, our specialty. No customer gets told “we don’t work on that.”
Our response time to San Diego addresses reflects real local knowledge. We know that a call from Point Loma (92106) might involve salt-air corrosion we won’t see in Lemon Grove, and that a Mission Hills (92103) job probably means working around balloon framing and finished attics with no chase space. That familiarity saves hours on every job.
From emergency calls to commercial buildouts, we handle heating work that most local shops won’t touch. 250+ customers who left reviews agree.
Our Heating & Furnace Services in San Diego
Furnace Repair
Furnace repair in San Diego usually means something very different than in Phoenix or Chicago. We’re often troubleshooting original wall furnaces in Ocean Beach cottages or gravity floor heaters in 1920s North Park bungalows. A typical furnace repair in San Diego runs $175–$825, depending on whether we’re sourcing a discontinued ignitor for a 1960s unit or replacing a modern gas valve. Salt-air corrosion in coastal ZIP codes like 92106 and 92107 attacks heat exchangers and burner assemblies faster than manufacturer estimates predict, so we inspect for that specifically.

Furnace Replacement
Here’s where San Diego gets interesting. Because most pre-1980s homes across Mission Hills, North Park, Hillcrest, and Ocean Beach were built with only a gas wall furnace or floor heater and zero ductwork, “heating replacement” here almost always involves a new ductless mini-split rather than swapping out an existing central furnace. This fundamentally changes the sales conversation, the scope of work, and the equipment mix compared to any neighboring city.
We recently serviced a 1925 Spanish Colonial Revival in Mission Hills where the original gravity floor furnace had rusted through its heat exchanger. The homeowner had no ductwork and didn’t want to tear into finished walls, so we installed a 3-zone ductless mini-split system with wall-mounted heads. That’s the norm for us: adapt historical homes to modern comfort without compromising their bones.
Furnace replacement in San Diego typically runs $4,130–$8,850, though many jobs land on the higher end when we’re adding multiple ductless zones to a home that never had central anything.

Furnace Tune-Up
Yes, a furnace tune-up is worth it even in San Diego’s mild climate. Our marine layer creates a hyper-local micro-climate gap: coastal ZIP codes like Ocean Beach (92107) and Point Loma (92106) sit under June-through-September overcast with highs in the upper 60s, while Mission Valley (92108), less than five miles inland in a natural heat-trapping canyon, can simultaneously hit the mid-90s. Your system cycles differently depending on where you live, and that wear pattern matters.
A furnace tune-up in San Diego costs $95–$235. We clean burner assemblies, test for carbon monoxide, check gas pressure, and inspect heat exchangers for cracks — especially critical in aging floor furnaces where decades of thermal cycling have taken their toll. For coastal properties, we add coil and fin inspection for salt corrosion.

Heat Exchanger Repair & Replacement
Cracked heat exchangers are the most serious heating problem we encounter in San Diego’s older housing stock. In pre-1950s bungalows with original floor furnaces, decades of thermal cycling with no maintenance create stress fractures that leak carbon monoxide into living spaces. This is not a repair to delay. We treat every heat exchanger inspection as a safety priority, and we’ll show you the crack with a borescope camera before discussing options.
In many San Diego cases, the heat exchanger failure is the final straw that pushes a homeowner from repair to full system replacement, especially when the original unit is so old that replacement parts are obsolete.

Trusted Brands We Service in San Diego
We maintain factory-trained compatibility across nine major brands: Carrier, Trane, Lennox, Goodman, Rheem, York, Daikin, Bryant, and American Standard. For San Diego customers, that breadth matters more than in most markets. When you’re trying to match a new ductless system to an existing layout in a 1930s Mission Hills bungalow, or sourcing a gas valve for a discontinued wall furnace in City Heights, brand flexibility keeps projects moving. We stock common parts for Trane, Lennox, Goodman, and Rheem locally, which means faster turnaround on repairs and fewer return trips for San Diego homeowners.
Common Heating & Furnace Problems We See in San Diego Homes
- Salt-air corrosion on coastal units. Outdoor condenser units within a mile of the ocean in ZIP codes 92106, 92107, and 92109 corrode coil fins and electrical contacts noticeably faster than manufacturer life-cycle estimates. We routinely find aluminum fin corrosion on units as young as four years old, and recommend annual coil coating for properties in these areas.
- Cracked heat exchangers in aging floor furnaces. Common in pre-1950s bungalows throughout North Park (92104) and City Heights (92105). Decades of thermal cycling with no maintenance creates stress fractures. This is a genuine safety hazard requiring immediate professional attention.
- Pilot light or gas valve failures in original wall furnaces. Parts for these units are often discontinued, forcing a full system replacement rather than a simple repair. We see this frequently in pre-1980s homes across Hillcrest and Ocean Beach.
- Sizing mismatches from climate assumptions. San Diego’s micro-climates mean a furnace properly sized for Ocean Beach may be completely wrong for Mission Valley. We spec equipment for the specific address, not the city average.
Pricing for Heating & Furnace in San Diego, CA
Honest pricing starts with honest ranges. Here’s what heating and furnace work costs in the San Diego market:
| Service | Price Range in San Diego |
|---|---|
| Furnace Repair | $175–$825 |
| Furnace Replacement | $4,130–$8,850 |
| Furnace Tune-Up | $95–$235 |
Several factors push costs toward the higher end. Coastal corrosion damage often requires more extensive parts replacement than inland failures. Homes without existing ductwork, which describes most pre-1980s properties in Mission Hills, North Park, and Ocean Beach, need ductless mini-split systems that run higher than simple furnace swaps. Access matters too: finished attics with no chase space, common in 1920s–1950s craftsman bungalows, add labor hours.
We provide upfront pricing before any work begins. Call (844) 560-6978 for a free estimate on your San Diego heating project.

FAQs — Heating & Furnace in San Diego
We can repair most floor furnace ignition issues, though parts availability for 1940s units varies. Gas valves and thermocouples for some models are discontinued, which may mean replacement is the practical option. We’ll inspect the unit, show you exactly what’s failed, and give you a straight repair-versus-replace recommendation. Call (844) 560-6978 for a free estimate.
Yes, the City of San Diego requires a permit for gas wall heater replacement, and the work must pass inspection. We handle permit submission and scheduling as part of our replacement service, so you’re not navigating city paperwork alone. This is especially important in older neighborhoods like Hillcrest and City Heights where inspectors are familiar with pre-1980s housing stock and want to verify proper venting and gas line sizing.
Salt air accelerates corrosion on outdoor condenser coils, electrical contacts, and even nearby gas line fittings in ZIP codes 92106 and 92107. We routinely find aluminum fin corrosion on units as young as four years old, far earlier than manufacturer estimates predict. Annual coil coating and more frequent tune-ups are worth the investment for Point Loma properties.
We can, though we often recommend evaluating whether a ductless mini-split or heat pump makes more sense. Mission Valley’s heat-trapping canyon geography creates wider temperature swings than coastal San Diego, so proper sizing is critical. If your ductwork is in good condition and properly sized, we’ll install a furnace that matches your cooling system’s airflow. If the ducts are leaky or undersized, we’ll show you the numbers on ductless alternatives.
Yes, because mild doesn’t mean zero wear. San Diego’s marine layer and micro-climate variations mean your system cycles differently than equipment in hotter or colder regions. A tune-up catches cracked heat exchangers, gas pressure drift, and salt corrosion before they become safety hazards or expensive failures. At $95–$235, it’s the cheapest insurance against a mid-winter emergency call. Call (844) 560-6978 to schedule.
