Fast, Reliable Heat Pump & Mini Split Across Florence-Graham
Heat pump and mini split installation in Florence-Graham typically runs $3,500–$7,500, with repairs starting at $150.

Call (855) 467-1888 for a free estimate.
We’ve worked the tight lots and alley-loaded properties of Florence-Graham long enough to know the drill: limited parking on Graham Avenue, linesets that need to run through side yards or over rooftops, and landlords who need multi-zone cooling without tearing into 1950s stucco. Our Heat Pump & Mini Split team handles everything from single-room ductless units to full building conversions. Jason Trent supervises every install personally.
Why Stonegate Heating & Air California Is Florence-Graham’s Preferred Heat Pump & Mini Split Company
We’ve got 16 years in California HVAC and nearly 500 verified reviews at 4.7 stars — but what matters in Florence-Graham is showing up with the right approach for the housing stock. This isn’t suburban Sacramento with open crawl spaces and 200-amp panels. It’s dense, it’s older, and the permit path is different.
Jason Trent serves as Field Supervisor, not a back-office owner. That means he’s on your job site, not dispatching techs from a desk. In Florence-Graham, that matters because the workarounds for tight clearances and aging electrical need real-time decisions. A tech who needs to call a manager for approval on a panel upgrade loses the day.
Our Florence-Graham customers find us the same way most do: they check reviews first. Nearly 500 of them, averaging 4.7 stars, built over 16 years of continuous operation. That volume means we’ve handled the specific failure patterns this area throws at equipment — oversized units short-cycling on uninsulated bungalows, condensate lines clogging from Alameda Corridor dust, 100-amp panels that can’t handle a modern mini split load.
Response time to Florence-Graham is typically same-day or next-morning. We’re familiar with the area’s access constraints: alley-loaded duplexes off Florence Avenue, street parking that requires coordination, and the need to work around tenants in multi-unit conversions. We plan for it before we arrive.
Our Heat Pump & Mini Split Services in Florence-Graham
Mini Split Installation
This is our most called-for service in Florence-Graham, and for clear reasons. The dominant housing stock — 1940s to 1960s stucco bungalows and subdivided duplexes — was built without central air. Window units were pieced in over decades. Ductwork, where it exists, is undersized, deteriorated, or routed through unconditioned attic space that cooks it in summer. A ductless mini split bypasses all of that.
We size carefully for the urban heat island effect here. Florence-Graham runs 5–10°F hotter than coastal LA in summer due to impervious surfaces and industrial land use along the Alameda Corridor. An undersized unit won’t keep up. An oversized one short-cycles, fails to dehumidify, and dies early. We run Manual J load calculations that account for your actual conditions, not regional averages.
Multi-Zone System
Landlords and owner-occupants with converted units call us regularly for this. A single outdoor condenser feeding multiple wall-mounted heads lets each tenant control their own temperature without shared ductwork or billing disputes. We serviced a 1950s stucco duplex on Graham Avenue where the landlord wanted a multi-zone mini split to cool three units without ductwork. The 100-amp panel couldn’t handle the load, so we upgraded it to 200 amps and installed a Daikin multi-zone system with three wall-mounted heads, routing linesets through the alley to avoid disturbing tenants.
Permits for multi-zone work in Florence-Graham go through LA County Building & Safety’s unincorporated portal. We handle that submission, the load calculations, and the electrical coordination. Cross Florence Avenue into Huntington Park and you’re dealing with an entirely separate city permit system, fee schedule, and inspector pool. That boundary awareness is day-one knowledge for anyone working this area.
Ductless System
For homeowners who want cooling without the invasive duct install, ductless is the straightforward path. One outdoor unit, one or more indoor heads, refrigerant lines run through a small wall penetration. In Florence-Graham’s tight lots, where side yards might be four feet wide and attic access is through a ceiling hatch, ductless often becomes the only practical solution.
We stock parts for Daikin, Bryant, Carrier, and American Standard systems, which keeps turnaround short when a Florence-Graham customer needs a replacement component fast.
Heat Pump Repair
Heat pumps work hard here. The same unit provides heating and cooling, and Florence-Graham’s temperature swings — cool winter mornings, blazing summer afternoons — mean more cycles per year than milder climates. Common issues we see: refrigerant leaks from vibration on rooftop mounts, failed reversing valves, and compressor strain from electrical undervoltage on aging panels.
Repairs run $150–$650 depending on the component. We diagnose before we quote, and we’ll tell you straight if a repair is throwing good money at a unit that’s reached end of life.

Trusted Brands We Service in Florence-Graham
We’re certified to work on nine major HVAC brands: Carrier, Trane, Lennox, Goodman, Rheem, York, Daikin, Bryant, and American Standard. For Florence-Graham customers, that means no “we don’t service that brand” dead end. We stock common parts for Daikin, Bryant, and Carrier mini split systems locally, which matters when you’re running a rental property and a down unit means a tenant complaint. Whatever brand you have, one team handles it. From a single-room mini split to a full commercial system, we cover the scope without passing you to a different contractor.
Common Heat Pump & Mini Split Problems We See in Florence-Graham Homes
- Oversized units cycling rapidly on bungalows with poor insulation. The combination of small square footage and zero wall insulation in pre-1960s stucco construction tempts some installers to spec too much capacity. The unit blasts cold air, shuts off, and repeats. Humidity stays high, equipment wears fast, and your electric bill climbs. We size to the actual envelope, not the floor plan.
- Condensate line clogs from dust and particulate near the Alameda Corridor. Freight rail and industrial activity along this corridor elevate particulate matter in Florence-Graham’s air. Mini split condensate drains, especially on rooftop or exterior-mounted units, clog faster here than in cleaner air basins. We install cleanable traps and recommend filter schedules that match actual local conditions.
- Electrical panel overloads when adding mini splits to 100-amp service. Most Florence-Graham bungalows still run original 100-amp panels. A multi-zone mini split can pull 30–50 amps at startup. Add a refrigerator, window AC in another room, and a laundry circuit, and you’re at breaker-trip territory. We assess panel capacity before we spec equipment, and we coordinate upgrades when needed.
- Failed compressor contactors from voltage fluctuation. Older grid infrastructure in this unincorporated area sees more voltage sag during peak summer load than incorporated cities with newer infrastructure. Heat pump compressors are sensitive to low voltage. We check supply voltage under load and recommend hard-start kits or line conditioning where the grid’s weak.
Pricing for Heat Pump & Mini Split in Florence-Graham, CA

FAQs — Heat Pump & Mini Split in Florence-Graham
Yes, and it goes through LA County Building & Safety, not a city department, because Florence-Graham is unincorporated LA County. We pull that permit as part of every install. Call (855) 467-1888 and we’ll handle the paperwork — estimates are free.
Yes, that’s exactly what ductless mini splits are designed for. We install the outdoor condenser and run refrigerant lines through a small wall penetration to indoor wall-mounted heads — no ductwork needed. We’ve done this routinely on Graham Avenue properties and similar Florence-Graham bungalows.
Usually not without an upgrade. A multi-zone mini split can draw 30–50 amps at startup, and most Florence-Graham bungalows still have original 100-amp service. We assess your actual load during the estimate and coordinate the panel upgrade if needed. Call (855) 467-1888 to schedule that assessment.
Expect $3,500–$7,500 for a complete mini split installation in Florence-Graham. Single-zone systems on accessible walls with existing electrical run toward the lower end. Multi-zone systems requiring panel upgrades and complex lineset routing run higher. We quote exact after inspecting your property — call (855) 467-1888 for a free estimate.
Florence-Graham’s urban heat island pushes temperatures 5–10°F above coastal LA, and window units aren’t sized for that sustained load. They’re also inefficient, noisy, and they block egress windows. A properly sized mini split handles the actual cooling demand, runs quieter, and doesn’t sacrifice your window. Call (855) 467-1888 and we’ll spec a replacement that works.
