Fast, Local Heating and Furnace Service
San Diego winters are mild compared to most of the country, but that doesn’t mean a broken furnace is a minor problem. Nights in neighborhoods like Rancho Bernardo and Alpine regularly drop into the 30s between December and February, and a heating system that hasn’t been serviced in a few years often picks the coldest week to fail. We respond quickly to calls across San Diego and aim to get a technician to you the same day for most heating and furnace situations.
Our service vehicles are stocked with parts for the most common furnace brands and failure types – Carrier heat exchangers, Trane Ignitor Replacement assemblies, Lennox control boards, Goodman draft inducer motors. That kind of parts inventory isn’t an accident; it’s what 13 years of San Diego-area service calls teaches you to carry. Gregory Hahn built the diagnostic process around fixing the actual problem on the first visit, not scheduling a return trip because the right part wasn’t on the truck.
We also handle emergency heating calls. San Diego doesn’t see blizzards, but a failed furnace with elderly residents or young children in the house is urgent no matter the ZIP code. Call (844) 875-9451 and tell us what’s happening – we’ll give you an honest assessment of how fast we can get there.
Heating and Furnace Services We Provide
Redwood Heating & Air handles the full range of residential and commercial heating work in Heating & Furnace in San Diego. That includes:
- Furnace repair – From failed igniters and cracked heat exchangers to faulty limit switches and blower motor failures. We diagnose across Carrier, Trane, Lennox, Goodman, Rheem, York, Daikin, Bryant, and American Standard equipment.
- Furnace installation and replacement – When a repair doesn’t make financial sense, we’ll give you a straight answer and quote a replacement on equipment that actually fits your home’s load – not whatever brand we happen to push.
- Heat pump service – San Diego’s climate makes heat pumps the right call for many homes. We service and install them alongside traditional gas furnaces.
- Heating tune-ups and maintenance – A pre-season inspection catches small problems before they turn into cold-night emergencies. This is especially important in San Diego’s inland valleys where equipment can go years without a real workout.
- Commercial heating systems – Rooftop units, multi-zone systems, and packaged HVAC for small to mid-size commercial properties across the San Diego area.
One thing worth knowing: San Diego’s gas furnaces tend to see a specific set of failure patterns because they sit idle for most of the year. Cracked heat exchangers from thermal cycling, clogged condensate drains on high-efficiency units, and corroded flame sensors from coastal humidity are among the most common issues Gregory’s team diagnoses every fall. If your furnace is short-cycling, producing a sulfur smell near the vents, or just not reaching the thermostat setpoint, those are the first things we check.
High-tension furnace components – including heat exchangers and gas valve assemblies – carry real safety risk if mishandled. We’re not going to walk you through those repairs on a page because they genuinely require a trained technician with the right tools and gas-safety certification. If you’re smelling gas near your furnace, leave the house, don’t touch the thermostat, and call your gas provider and then us.
Why San Diego Homeowners Call Redwood Heating & Air
Most HVAC companies in San Diego are either factory-authorized dealers for one brand or general contractors who treat heating as a side service. Redwood Heating & Air was built differently from the start. Gregory Hahn holds a Master Technician designation – the technical ceiling for field technicians in this trade – and he structured the company around multi-brand fluency because that’s what actually serves customers.
If you have a Trane gas furnace in a Mission Hills craftsman and a Daikin mini-split in the bonus room addition, we service both. We don’t tell you the Daikin isn’t our department. That sounds like a small thing until you’ve dealt with two separate HVAC companies diagnosing around each other’s work.
The 428 reviews and 4.6-star average weren’t built on new-customer discounts or incentivized ratings – they were built on 13 years of repeat calls from homeowners who got a straight answer and a repair that held. If you want to see what the home base of this operation looks like and what full-spectrum HVAC service means in practice, start there.

Areas We Cover Near San Diego
Redwood Heating & Air serves San Diego and a wide network of surrounding communities. If you’re in Coronado dealing with a heat pump that stopped producing heat overnight, in the Citrus Hills area of the inland valley with a furnace that won’t ignite, or in West Covina or Covina needing a furnace replacement before the cold season sets in, we’re the team to call. We also cover Azusa, Fremont, and Olivehurst for customers who’ve found us through search and need a credible technician to come out.
In San Diego proper, we regularly work in neighborhoods including Mission Hills, North Park, Rancho Bernardo, Scripps Ranch, La Mesa, El Cajon, Chula Vista, and Point Loma. Coastal communities like Coronado see different failure patterns than inland areas – salt air accelerates corrosion on cabinet components and electrical contacts – and we factor that into our diagnosis.

Frequently Asked Questions
How fast can you get to me for a heating or furnace repair in San Diego?
For most heating and furnace calls in San Diego, we can schedule same-day service. Emergency calls – furnace completely out, gas smell near the unit, no heat with vulnerable household members – get priority scheduling and we’ll give you a realistic arrival window when you call. The best way to get an accurate timeframe is to call (844) 875-9451 directly. We don’t use automated dispatch; you’ll talk to someone who knows the schedule and can commit to a time.
Do you serve my area if I’m not in central San Diego?
Yes. We cover San Diego and a broad surrounding area including Coronado, West Covina, Covina, Azusa, Citrus, Fremont, and Olivehurst, along with San Diego neighborhoods from Chula Vista to Rancho Bernardo. If you’re outside those areas, call us at (844) 875-9451 – we’ll be straight with you about whether we can get there same day or need to schedule ahead.
How much does furnace repair typically cost in San Diego?
Furnace repair in San Diego most commonly runs between $120 and $700 depending on what failed. A flame sensor cleaning or igniter replacement lands in the $120-$280 range; blower motor failures typically run $400-$700; heat exchanger work can reach $900-$1,800. If you’re wondering How Long Does a Furnace Last? (San Diego, CA), that factors into whether repair or replacement makes more sense. We diagnose first and give you an exact quote before touching anything. Call (844) 875-9451 for a free estimate – we won’t bill you just to come out and assess.
Do you handle heating calls after business hours or on weekends?
We handle emergency heating service outside normal business hours for San Diego and nearby areas. If your furnace fails on a weekend evening or a holiday, call (844) 875-9451 and explain the situation. Gregory Hahn built Redwood Heating & Air around the reality that HVAC equipment doesn’t fail on a schedule, and we respond accordingly.
Is it worth repairing my furnace, or should I replace it?
The honest answer depends on the unit’s age, what failed, and your efficiency goals. A furnace under 10 years old with a minor part failure is almost always worth repairing. A 20-year-old furnace with a cracked heat exchanger is usually a replacement candidate – both for cost reasons and because a cracked heat exchanger can allow combustion gases into living space, which is a safety issue, not just a comfort issue. Gregory Hahn will give you a direct recommendation after diagnosis, not a default push toward whatever generates the larger ticket. Call (844) 875-9451 to schedule a diagnostic and get a straight answer.
What brands of furnace do you work on?
We service Carrier, Trane, Lennox, Goodman, Rheem, York, Daikin, Bryant, and American Standard heating equipment. Most single-brand HVAC companies in San Diego will tell you they can “look at anything” but only truly know one or two product lines. Gregory Hahn’s 13 years of multi-brand field work means the diagnostic process is grounded in real knowledge of how each manufacturer designs their controls, heat exchangers, and fault codes – not a best guess from a tech trained on one brand.
