Fast, Reliable Heat Pump & Mini Split Across Los Angeles
Heat pump and mini-split installation in Los Angeles typically costs $4,130–$8,850 for a full system, with repairs running $175–$765 depending on the issue. Most Los Angeles homeowners with pre-1950 bungalows or courtyard apartments choose ductless mini-splits because their homes were built without ductwork, making traditional central air far more invasive and expensive. If you’re in Koreatown, Echo Park, or Silver Lake and need same-day service, call us at (855) 467-1888.
We’ve been installing and repairing heat pumps and mini-splits across Los Angeles for 16 years. Owner Jason Trent supervises every project personally, and our team is factory-experienced on nine major brands. From a single-room mini split to a full multi-zone system, we handle the unique challenges of Los Angeles housing stock: shallow crawl spaces, slab-on-grade foundations, salt-air corrosion, and Title 24 compliance that out-of-state contractors often miss.
Why Stonegate Heating & Air California Is Los Angeles’s Preferred Heat Pump & Mini Split Company
Our reputation in Los Angeles is built on 499 verified reviews averaging 4.7 stars, earned across hundreds of real jobs, not cherry-picked testimonials. Homeowners in ZIP codes 90030, 90031, 90032, and 90033 call us because we’ve solved the exact problems their homes present: no existing ductwork, tight mechanical spaces, and coastal air that eats HVAC equipment alive.
Jason Trent doesn’t run this company from a back office. He holds the title of Field Supervisor and is physically present on job sites, accountable for every mini-split line-set route and heat pump placement. Where franchise chains send whichever tech is available, you get experienced, owner-accountable hands on every Los Angeles job.
We carry parts and equipment for Carrier, Trane, Lennox, and the other major brands we service, which means faster turnaround for Los Angeles customers. No waiting a week for a coil or control board to ship from out of state.
Our familiarity with Los Angeles building patterns matters. The 90001–90010 corridor is dominated by pre-1950 wood-frame bungalows and two-story courtyard apartments originally fitted only with floor furnaces or wall heaters. We’ve routed mini-split line-sets through attics, closets, and exterior walls in these homes dozens of times. We know which walls are load-bearing, where the electrical panel has spare capacity, and how to get refrigerant lines from a rooftop condenser to a third-floor unit without destroying original plaster.
Our Heat Pump & Mini Split Services in Los Angeles
Ductless System Design & Installation
Most Los Angeles homes built before 1950 were never designed for central air. The Mediterranean climate made it unnecessary, and builders saved money by skipping ductwork entirely. Today, summer heat events are intensifying, and buyers expect cooling. We design ductless systems specifically for these homes, placing indoor air handlers where they’ll work without gutting walls or adding soffits. In View Park-Windsor Hills and surrounding areas, we’ve replaced wall furnaces with ductless heat pumps that heat and cool from the same unit, eliminating the need for separate heating and cooling systems.
Mini Split Installation
Our mini split installs in Los Angeles focus on homes with zero existing duct infrastructure. We recently installed a Daikin multi-zone mini-split in a 1925 craftsman bungalow on West Pico Boulevard near Vermont Avenue, replacing a wall furnace. The crawl space was so shallow we had to route line-sets through the attic and down interior closets. The homeowner chose a ductless system because adding ductwork to the existing slab-on-grade was cost-prohibitive. This is typical in Los Angeles: the job is less about swapping equipment and more about engineering a first-ever cooling solution.
Multi-Zone System Installation
A multi-zone mini-split lets you control temperature room by room, which matters in Los Angeles’s varied housing stock. A courtyard apartment in 90006 might have four units with different sun exposure. A 1920s bungalow in Echo Park has a south-facing living room that bakes in afternoon sun while bedrooms stay cool. We size each zone independently and place condensers where Santa Ana winds won’t blast debris into the coils.
Heat Pump Repair
Heat pump repair in Los Angeles often involves salt-air damage. The marine layer keeps nights mild, but coastal salt accelerates corrosion on outdoor coils and electrical connections. We see refrigerant leaks from pinhole corrosion in copper line-sets, failed capacitors from salt-caked contactors, and seized fan motors from bearing contamination. Our repairs address the root cause, not just the symptom, because fixing a leak without treating the surrounding corrosion means you’ll call again in two years.
Heat Pump Installation
Full heat pump installation in Los Angeles requires navigating California’s Title 24 energy code, which mandates HERS field verification and duct-leakage testing on virtually any new HVAC installation. SCAQMD Rule 1111 has already banned low-efficiency atmospheric furnaces in the South Coast air basin. Every permit-pulled job in Los Angeles carries compliance costs and paperwork that contractors just across the Nevada or Arizona border never deal with. We handle permits, HERS testing, and utility rebate paperwork as part of our standard process.
Mini Split Repair
Mini split repair in Los Angeles homes often traces back to installation details unique to local conditions. Snapped condensate drain lines are common in warm, humid months when attics and crawl spaces heat up. We route drain lines with proper slope and insulation, and we install safety switches that shut the unit down before water damage occurs. Clogged outdoor coils from Santa Ana wind debris are another frequent call; we clean and coat coils to resist future buildup.

Trusted Brands We Service in Los Angeles
Whatever brand you have, we can service it. Our technicians are factory-trained or deeply experienced on nine leading HVAC brands: Carrier, Trane, Lennox, Goodman, Rheem, York, Daikin, Bryant, and American Standard. For Los Angeles customers, this means no “we don’t service that brand” dead end. We stock common parts locally for Carrier, Trane, and Lennox systems, and we can source Daikin mini-split components quickly through regional distribution. This multi-brand fluency matters when you’re trying to match a new system to existing equipment in a multi-unit courtyard building, or when you need a repair on a brand the previous installer abandoned.
Common Heat Pump & Mini Split Problems We See in Los Angeles Homes
- Salt-air corrosion of outdoor coils and fins. In coastal Los Angeles, salt air corrodes mini-split condenser coils and outdoor unit fins within 3–5 years, causing refrigerant leaks and reduced efficiency. We specify coastal-grade aluminum fins and apply protective coatings during installation.
- Condensate drain line failures in tight attic drops. We frequently see snapped condensate drain lines in warm, humid months, leading to water damage in attics or crawl spaces where our crew routes drain lines through tight drops. We use reinforced, UV-stable tubing and secure it against vibration.
- Santa Ana wind debris clogging outdoor units. Santa Ana wind events blow fine sand and debris into outdoor condenser units, clogging coils and overheating compressors during sudden 100°F heat spikes. We install debris screens and recommend quarterly coil cleaning for homes in exposed locations.
- Undersized systems in converted garages or additions. Many Los Angeles homeowners add a mini-split to a converted garage or back house without calculating the heat load from uninsulated slab, single-pane windows, and west-facing walls. We run Manual J load calculations and size equipment for actual conditions, not square-footage rules of thumb.
Pricing for Heat Pump & Mini Split in Los Angeles, CA
Here’s what Los Angeles homeowners can expect to pay for heat pump and mini-split work:
| Service | Price Range in Los Angeles |

| AC Repair (includes heat pump & mini-split) | $175–$765 |
| AC Installation (includes heat pump & mini-split systems) | $4,130–$8,850 |
| Tune-Up & Maintenance | $95–$235 |
Installation costs vary based on how many indoor zones you need, whether we can use existing electrical, and how complex the line-set routing is. A single-zone mini-split in a 1920s bungalow with easy attic access runs toward the lower end. A four-zone multi-split with line-sets dropped through three closets and a HERS verification runs higher. Repairs depend on whether we’re patching a corroded coil or replacing a compressor. We provide upfront pricing before any work begins, and estimates are free. Call (855) 467-1888 to schedule.

FAQs — Heat Pump & Mini Split in Los Angeles
Yes, virtually all mini-split installations in Los Angeles require a permit and HERS field verification under California Title 24. We pull permits, schedule inspections, and coordinate HERS testing as part of our standard installation process. Call (855) 467-1888 and we’ll walk you through what’s needed for your specific property.
Salt-laden coastal air accelerates corrosion on copper tubing, fittings, and aluminum fins, often causing refrigerant leaks and efficiency loss within 3–5 years instead of the 10–15 years you’d see inland. We mitigate this with coastal-grade hardware, protective coil coatings, and corrosion inspections during tune-ups. If you’re within a few miles of the beach, mention it when you call so we can spec accordingly.
Yes, ductless mini-splits are specifically designed for homes without ductwork, and they’re the most practical cooling solution for Los Angeles’s pre-1950 bungalows. We route refrigerant lines and power through attics, closets, or exterior walls, placing the indoor unit where it won’t disrupt original plaster or trim. Most installations take one to two days with minimal disruption.
A properly sized mini-split will handle Santa Ana wind heat spikes, but only if the outdoor unit is protected from debris and the system was sized for Los Angeles’s actual design temperatures, not average conditions. We size for 100°F+ days, install debris screens, and place condensers where wind-blown sand won’t clog coils. If your current system struggles during September–November heat events, call us for a load calculation review.
We service and install nine major brands: Carrier, Trane, Lennox, Goodman, Rheem, York, Daikin, Bryant, and American Standard.
