Why Stonegate Heating & Air California Is Home Gardens’s Preferred Heating & Furnace Company
We’ve been serving the Inland Empire for 16 years, and Home Gardens has become one of our most frequent call zones. Owner Jason Trent supervises every project as Field Supervisor, so when you hire Stonegate, you’re getting leadership that’s physically on your property, not dispatching from a back office in another county.
Our 499 verified reviews average 4.7 stars across platforms, and a meaningful share come from Home Gardens homeowners who found us after frustrating experiences with Corona-based contractors who stumbled over the county-city jurisdictional split. Because Home Gardens is unincorporated, all HVAC permits and inspections run through Riverside County Building & Safety, not the City of Corona. Contractors who assume city jurisdiction waste days on paperwork corrections. We don’t. We file county permits correctly the first time.
That permit fluency translates to faster turnaround for Home Gardens residents. We’re also accustomed to the longer service drives that rural acreage properties require, and we stock parts for Carrier, Trane, Lennox, and Goodman systems so we’re not making second trips.
Our Heating & Furnace Services in Home Gardens
Furnace Repair
Furnace repair in Home Gardens runs $150–$700 depending on the component and accessibility. We see a lot of ignitor failures and gas valve issues in the older housing stock near Home Gardens Park, where original furnaces from the 1960s and 1970s are still running on borrowed time. The degraded attic ductwork common here compounds the problem, making a furnace work harder to push air through leaky, undersized runs. We diagnose the full system, not just the broken part, because fixing a furnace while ignoring 30% duct loss is a temporary patch at best.
Furnace Replacement
A full furnace replacement in Home Gardens typically falls between $3,500–$7,500, including equipment, labor, and necessary duct modifications. This is where our county-permit expertise matters most. Riverside County Title 24 and HERS testing requirements are stricter than many homeowners expect, especially when replacing a furnace connected to original ductwork that was never designed for modern airflow rates. We replaced a 1970s furnace in a ranch-style home on Chandler Street where the original attic ductwork was undersized and had severe leakage. After diagnosing inadequate return-air capacity, we ran new R-8 ducts to meet current Riverside County Title 24 and HERS requirements, then installed a 96% AFUE Carrier gas furnace with a variable-speed blower to handle the heavy cooling load. The job took one trip because we pre-ordered the county permit and accounted for the unpermitted garage conversion that had been tapped into the old system.
Furnace Tune-Up
Annual furnace tune-ups in Home Gardens cost $80–$200 and pay for themselves in efficiency gains alone. Given the Santa Ana wind events that stress systems each fall, we recommend scheduling before September. Our tune-up covers heat exchanger inspection, burner cleaning, gas pressure verification, and duct pressure testing. On older systems, we specifically check for cracked heat exchangers, a safety issue that’s more common in furnaces that have cycled heavily through decades of Riverside County temperature swings.
Heat Exchanger Inspection & Replacement
Heat exchanger failure is a serious safety matter. In Home Gardens’s older housing stock, we find cracked exchangers at higher rates than in newer communities, largely due to decades of thermal cycling in furnaces that were often oversized for the original square footage. A cracked heat exchanger can leak carbon monoxide into living spaces. We use combustion analyzers and visual inspection protocols to verify integrity. If replacement is needed, we factor in whether your existing duct system can handle a modern, properly sized furnace, or whether the county will require duct upgrades as part of the permit.

Trusted Brands We Service in Home Gardens
We’re experienced with nine major HVAC brands: Carrier, Trane, Lennox, Goodman, Rheem, York, Daikin, Bryant, and American Standard. For Home Gardens customers, this means whatever furnace is in your home, we’ve likely serviced it before. We stock common ignitors, gas valves, and control boards for Carrier, Trane, Lennox, and Goodman systems locally, which keeps repair timelines short even for same-day calls. No “we don’t service that brand” dead ends. No waiting a week for parts from Los Angeles.
Common Heating & Furnace Problems We See in Home Gardens Homes
- Degraded attic ductwork from decades of extreme heat. Home Gardens attics regularly exceed 140°F in summer, baking flexible duct insulation and causing seams to fail. By winter, that damage shows up as weak airflow and rooms that never get warm.
- Furnaces oversized for modified floor plans. Original 900-square-foot tract homes that grew through unpermitted additions now have furnaces cycling on and off too quickly, wasting gas and wearing components prematurely.
- Santa Ana wind pressure imbalances. Those dry, hot fall winds create negative pressure conditions that can backdraft combustion appliances and trip pressure switches on modern furnaces with sealed combustion.
- Detached workshops and outbuildings with no heat. Rural acreage properties often have unconditioned workshops that homeowners want to heat for hobbies or home businesses, requiring new duct runs or dedicated mini-split systems that must be permitted through Riverside County.

FAQs — Heating & Furnace in Home Gardens
Yes. Because Home Gardens is unincorporated, all furnace replacements require a Riverside County Building & Safety permit, not a City of Corona permit, even though both share the 92879 ZIP code. We handle the full permit application, scheduling, and inspection coordination as part of our replacement service. Call (855) 467-1888 and we’ll walk you through the timeline.
We can, and we regularly do for Home Gardens acreage properties. The solution depends on distance from your main furnace, load calculation for the workshop, and whether Riverside County will require a separate permit for the new duct run. Sometimes a dedicated mini-split is more practical than extending central heat. We’ll assess both options during a free site visit.
Santa Ana winds create pressure differentials that can interfere with combustion air supply and cause backdrafting in older, atmospherically vented furnaces. The rapid humidity drop also makes the air feel colder than the thermostat reading, so your system works harder. If this happens consistently, your furnace may need a combustion air upgrade or the venting may require modification to meet current county code. Call (855) 467-1888 for diagnostics.
We can address the heating, but we document the unpermitted conversion carefully before touching any equipment. Riverside County may require that space to be brought into compliance before we can legally extend ductwork to it. We’ve navigated this scenario many times in Home Gardens’s older housing stock. We’ll give you a clear path forward that protects you from liability and gets the space comfortable.
Signs include weak airflow at distant registers, excessive noise from vents, and rooms that never reach set temperature. We measure static pressure and airflow at each register during our pre-replacement assessment. In Home Gardens, we find undersized ducts in roughly half the homes built before 1980. If yours fails testing, we’ll include proper duct resizing in your replacement quote so you pass HERS verification on the first inspection. Call (855) 467-1888 for a free evaluation.
