Why Stonegate Heating & Air California Is Temple City’s Preferred Air Quality & Ventilation Company
Temple City homeowners know their properties aren’t like Arcadia’s or Pasadena’s. The 1,200–1,800 square foot post-war ranches, the acreage lots with detached workshops, the shallow attics that hit 150°F in July — these conditions demand a contractor who’s actually worked here, not just driven through on the 10 Freeway. Jason Trent, our owner and Field Supervisor, supervises every project personally. That means when we’re threading ductwork through a low-slope roof near Encinita Avenue or hauling a boom truck down a half-mile gravel drive off Temple City Boulevard, the person accountable for the result is on-site, not in a back office.
Our numbers back this up: 16 years in business, nearly 500 verified reviews at a 4.7-star average. Temple City customers specifically mention our one-trip completion rate on retrofit jobs. We’ve earned that by carrying nine major HVAC brands worth of parts and knowledge — Carrier, Trane, Lennox, Goodman, and others — so we don’t waste a second trip ordering components.
Response time matters when your workshop’s air is thick with fumes or your ERV core has frozen solid. We route crews efficiently from our Sacramento base to Temple City’s 91780 zip, and we schedule with the reality of San Gabriel Valley traffic in mind. No vague “we’ll be there sometime Tuesday” windows.
Our Air Quality & Ventilation Services in Temple City
ERV/HRV System Installation
Temple City’s acreage properties with detached workshops are where ERV and HRV systems prove their worth. Standard residential units fail fast in these conditions — uninsulated attics, extreme temperature swings, and the dust load from woodworking or automotive work. We install heavy-duty Lennox and Carrier ERV/HRV systems rated for commercial-grade cycling, with cores that won’t crack from Temple City’s 150°F attic peaks. On a 2-acre property off Kauffman Avenue, we installed a Lennox HRV system in a detached woodworking shop where the homeowner had been dealing with fine sawdust and stagnant air. The job required threading ductwork through an uninsulated attic that hit 150°F in July, and we brought in a dedicated crew with a boom truck to manage the long service drive — all done in one trip, with no callbacks.
Air Filtration
Oversized workshop doors on Temple City acreage properties let in outdoor dust and pollen at volumes that overwhelm standard residential filters within weeks. We size filtration systems to actual load, not square footage. For workshops housing HVAC equipment, we specify high-MERV filters with sufficient surface area to prevent airflow restriction. A typical high-MERV air filter upgrade for a Temple City workshop runs $80–$200 installed. We’ve replaced too many systems where a homeowner installed a filter rated for a 2,000 square foot house in a space generating ten times that particulate load.
Ventilation Install
Temple City’s 1950s–1970s ranch homes were built without central air — floor furnaces or wall heaters only — which means many lack any duct infrastructure for ventilation. Adding whole-house ventilation to these homes requires designing supply and return paths through attics with minimal clearance and low-pitch roofs. We’ve retrofitted dozens of these properties, often mid-renovation when a room addition or garage conversion has changed the load calculation. The city’s active renovation market means we’re regularly called to extend or reroute ductwork after the homeowner’s contractor has already opened walls.
Humidifier & Dehumidifier Install
Temple City’s inland location in the San Gabriel Valley basin creates sharp seasonal swings — summer highs hitting 100–108°F with bone-dry conditions, winter nights that can drop into the 30s with surprising humidity spikes. Whole-house humidifiers protect original hardwood floors common in these post-war ranches. Dehumidifiers become critical for homes with slab foundations where moisture wicks upward during winter rain events. For homes without existing ductwork, we design standalone solutions rather than forcing inappropriate central-system add-ons.
UV Air Purifier
UV-C systems installed at the coil address the mold and bacterial growth that thrives in Temple City’s high-run-time summer conditions. When your AC is working 12–14 hours a day for weeks straight, the evaporator coil stays wet. UV purifiers keep the coil clean, which maintains airflow and efficiency through the hottest months.

Trusted Brands We Service in Temple City
We carry factory-trained experience on nine major HVAC brands: Carrier, Trane, Lennox, Goodman, Rheem, York, Daikin, Bryant, and American Standard. For Temple City customers, this means no “we don’t service that brand” dead ends. We stock common parts for Carrier and Lennox ERV/HRV units locally, which keeps turnaround tight on a system that’s handling workshop fumes or keeping a home breathable during a heat event. Jason Trent has personally troubleshot Trane and Goodman ventilation systems in Temple City’s tight attic spaces, so the expertise on-site matches whatever equipment you’re running.
Common Air Quality & Ventilation Problems We See in Temple City Homes
- Oversized workshop doors overwhelming standard filters. Temple City’s acreage properties often have 10-foot or roll-up workshop doors that stay open for hours, pulling in pollen, dust, and agricultural particulate. Residential-grade filters clog in days and let fine particles pass. We spec commercial-surface-area filters with proper MERV ratings for the actual load.
- Long uninsulated duct runs pulling humid attic air. When ERV/HRV ductwork stretches from a detached garage or workshop through a 150°F attic, temperature differentials create condensation inside the core. Mold follows. We insulate aggressively and spec cores with antimicrobial coatings rated for these conditions.
- DIY filter swaps with wrong MERV ratings causing system freeze-ups. Self-reliant Temple City homeowners often upgrade to the highest MERV filter they can buy, not understanding that dense filtration restricts airflow below what the system’s blower can handle. The coil ices. The compressor strains. We size filters to the specific CFM capacity of the installed unit.
- Floor-furnace homes with no path for whole-house ventilation. That 1960s floor furnace in the hallway closet? No air handler, no ducts, no distribution. Adding ventilation means either designing a new central system from scratch or installing dedicated room-by-room solutions. We’ve done both, and we’ll tell you straight which approach fits your renovation plans and budget.
Pricing for Air Quality & Ventilation in Temple City, CA

What moves the needle on ERV/HRV cost: distance from main house to workshop, attic accessibility for duct runs, electrical capacity at the outbuilding, and whether we’re integrating with existing HVAC or starting from zero. The $3,500–$7,500 range covers most Temple City acreage properties we’ve worked. For a floor-furnace home adding full central ventilation for the first time, costs trend higher due to new ductwork design. We don’t guess over the phone.

FAQs — Air Quality & Ventilation in Temple City
Yes. We design ducted ERV/HRV systems that pull fresh air and exhaust stale air through roof penetrations or soffit connections, with the main unit mounted in the workshop attic or on an exterior pad. No window units needed, no wall demolition. On the Kauffman Avenue job, the workshop had zero windows and we completed the install without touching interior drywall. Call (855) 467-1888 to schedule a site visit — estimates are free.
We dispatch crew vehicles with sufficient capacity for the job, including boom trucks for lifting heavy ERV/HRV units over workshop roofs when ground access is limited. Our scheduling accounts for drive time and equipment staging. We’ve yet to encounter a Temple City property where we couldn’t get the right gear to the right building. For properties with restricted access, Jason Trent personally scouts the route during the estimate visit.
Standalone dehumidifiers are the practical solution for floor-furnace homes in Temple City. We install ductless units with dedicated drainage, sized to your square footage and slab conditions. Converting to a full ducted system is possible but requires a larger investment; we’ll quote both approaches honestly so you can decide. Many Temple City homeowners start with standalone and upgrade to central later during a major renovation.
A high-MERV pleated filter with expanded surface area, typically MERV 11–13 for woodworking dust, matched to your system’s blower CFM capacity. The wrong filter — too dense for the blower — causes freeze-ups and compressor damage. We test static pressure during installation to confirm the filter won’t restrict airflow. For Temple City workshops with heavy particulate loads, we also recommend a pre-filter stage that catches larger particles before they reach the main filter. Call (855) 467-1888 and we’ll spec the right combination for your equipment.
Yes, especially in winter when temperature differentials between the garage and attic are extreme. The core condenses moisture that ices when defrost cycles are insufficient. We see this on systems installed without proper insulation on intake lines, or on units undersized for the actual air volume. Our fix: inspect the defrost controls, add insulation to vulnerable duct runs, and verify the core is rated for the temperature swings of Temple City’s inland climate. If the unit was a DIY install or done by a generalist, the root cause is usually a specification mismatch. We can diagnose and correct it.
