We’re the Heating & Furnace team that actually drives to Ramona, not a dispatch center in another county. Owner Marcus Feldman still manages service calls personally, and after 19 years in this industry, he’s worked on virtually every furnace type you’ll find in the 92065 ZIP code. Ramona’s inland valley climate — summer highs over 105°F and winter nights in the upper 20s — demands systems built for real loads, not the mild assumptions that work 35 miles west on the coast. We’ve learned that the hard way, alongside homeowners who moved here expecting typical San Diego weather.
Why Crestview Heating & Air California Is Ramona’s Preferred Heating & Furnace Company
Our 4.8-star average across 250+ reviews reflects real jobs in real homes, including plenty here in Ramona. Customers on San Vicente Road, Warnock Drive, and throughout the Mussey Grade area have left feedback that mentions the same thing: Marcus shows up, diagnoses the actual problem, and doesn’t push equipment you don’t need.
That matters especially in Ramona, where the housing stock creates unique challenges. We’re not guessing when we inspect a 1978 Rheem or an original gravity furnace. We’ve replaced dozens of them. Our factory training covers nine major brands — Trane, Lennox, Goodman, Rheem, and others — so we’re not telling you to call someone else because “we don’t work on that.”
Emergency service is available when your furnace fails outside normal hours. Winter nights in Ramona drop hard and fast. We understand that a heat exchanger crack or gas valve failure at 10 PM isn’t a tomorrow problem.
Our Heating & Furnace Services in Ramona
Furnace Repair
A typical furnace repair in Ramona runs $150–$700 depending on the part and accessibility. We see a lot of failed ignitors and erratic gas valves in the older systems common here — 1970s and 1980s units that have cycled through thousands of Ramona’s 70–80°F annual temperature swings. We stock common ignitors and gas valve components for Trane, Lennox, Goodman, and Rheem systems to minimize wait time. When the part is obsolete, we’ll tell you straight and quote replacement instead of stringing you along.
Furnace Replacement
Furnace replacement in Ramona typically costs $3,500–$7,500 including equipment, duct modifications, and permit coordination. This is where our local experience pays off most. Ramona’s 1970s–1990s ranch homes often have original gravity-type or early forced-air furnaces with obsolete controls and heat exchangers, where replacement parts are no longer stocked and retrofitting a modern 80+% AFUE unit requires resizing ducts for today’s loads. We retrofitted a 1978 Rheem oil-to-gas furnace for a homeowner on Mussey Grade Road; the original unit had a cracked heat exchanger and the manufacturer discontinued the control board. We installed a two-stage Carrier propane furnace, upsized the duct to handle Ramona’s 40°F winter lows, and converted the orifice for the homeowner’s propane tank. That kind of job isn’t in every HVAC tech’s wheelhouse.
Furnace Tune-Up
A furnace tune-up in Ramona runs $80–$200 and should happen annually before the heating season. We check heat exchanger integrity, gas pressure and combustion, ignitor wear, and duct seal condition. In Ramona specifically, attic flex duct takes a beating from temperature extremes that degrade mastic seals faster than in coastal San Diego. We flag that during tune-ups because loose, dusty ductwork is one of the most common efficiency killers we find here.
Heat Exchanger Inspection & Replacement
Cracked heat exchangers are a safety issue we take seriously, and they’re common in Ramona’s legacy furnaces. Decades of thermal cycling in this valley’s wide temperature swings fatigue metal to the point of failure. We use visual inspection, combustion analysis, and camera inspection where access allows. If the heat exchanger is cracked and the unit is past 20 years, replacement usually makes more sense than hunting obsolete parts. We’ll show you what we found and explain your options without pressure.

Trusted Brands We Service in Ramona
We service and stock parts for Carrier, Trane, Lennox, Goodman, Rheem, York, Daikin, Bryant, and American Standard. For Ramona customers, that means faster turnaround on repairs and replacement equipment that fits your existing ductwork when possible. We regularly source Trane and Lennox equipment for local jobs, and we keep Goodman and Rheem components on hand for common repair scenarios. If you’ve got a propane setup on a rural parcel, we spec propane-compatible variants and handle orifice conversions in-house. No sending you to a third party.
Common Heating & Furnace Problems We See in Ramona Homes
- Cracked heat exchangers in 1970s–1990s furnaces. Decades of thermal cycling in Ramona’s wide temperature swings eventually crack the metal. We catch this during tune-ups or when a customer reports headaches, soot, or a strange smell. It’s a replacement situation, not a patch job.
- Obsolete gas valves and ignitors no longer manufactured. Many original furnaces in Ramona’s ranch neighborhoods used components that suppliers stopped stocking years ago. We check availability honestly; if the part is gone, we quote replacement with modern equipment sized for your home.
- Propane conversion issues on rural and semi-rural parcels. A large share of Ramona’s horse properties and ranches are on propane rather than SoCalGas natural gas infrastructure. Incorrect orifices and tank pressure mismatches lead to poor combustion and sooting. We perform orifice conversions and tank-pressure checks as routine work, something that’s rare in most of suburban San Diego County.
- Failed duct seals from attic temperature extremes. Ramona’s attic-run flex duct is subjected to temperature extremes that degrade mastic seals and duct connections far faster than in coastal communities. We see this in homes near San Vicente Road and throughout the older ranch neighborhoods.

FAQs — Heating & Furnace in Ramona
Probably not, and we’ll check honestly before quoting anything. Many gas valves from 1980s furnaces were discontinued years ago; if the part is unavailable, we quote replacement with a modern propane-compatible unit sized for your home’s actual heating load. Call (844) 560-6978 for a free inspection.
Yes, we perform oil-to-propane conversions regularly in Ramona’s older ranch neighborhoods. The job involves removing the oil burner, installing a propane gas valve and orifice, updating controls, and verifying combustion. We also assess whether your existing ductwork can handle a modern furnace’s airflow requirements. Call (844) 560-6978 to schedule an evaluation.
Ramona’s inland valley location at 1,400 feet elevation creates genuine four-season conditions with hard freezes and triple-digit summer heat, unlike coastal San Diego. That 70–80°F annual swing demands systems legitimately sized for both peak cooling and real heating loads, and it accelerates wear on heat exchangers and duct seals. Many Ramona homes were originally built with minimal HVAC because owners underestimated the climate, so retrofits often require duct upsizing that wouldn’t be necessary closer to the coast.
It’s common but not something to ignore. Ramona’s attic temperature extremes degrade mastic seals and duct connections faster than in coastal San Diego communities. Loose, dusty ductwork kills efficiency and pushes attic debris into your living space. We reseal and replace flex duct during tune-ups and replacement jobs. Call (844) 560-6978 for an inspection.
Either can work, but Ramona’s winter lows in the upper 20s and occasional sub-freezing nights make dual-fuel systems or high-performance cold-climate heat pumps worth considering. A furnace — especially propane where natural gas isn’t available — provides reliable heat regardless of outdoor temperature. We assess your home’s insulation, ductwork, and fuel source before recommending. Call (844) 560-6978 for a free consultation.
