Quick answer: APLA Construction (CA Lic #1136359) is a licensed HVAC contractor serving all of Greater Los Angeles — installation, replacement, and repair for central air, ductless mini-splits, heat pumps, and furnaces, plus commercial HVAC for small business build-outs. Most residential installations cost $3,500–$40,000 depending on system type; see the full pricing breakdown by system.
Los Angeles puts real demands on an HVAC system — extreme summer heat in the San Fernando and San Gabriel Valleys, older homes with no existing ductwork, and a statewide push toward electric heat pumps as gas furnaces and water heaters get phased out of new construction. Hiring a licensed, experienced HVAC contractor matters more here than in a mild climate, both for comfort and for staying ahead of California’s changing energy code.
APLA Construction (CA Lic #1136359) provides full HVAC installation, replacement, and repair services across Greater Los Angeles — from Sherman Oaks and Encino to Manhattan Beach, Glendale, and Pasadena. We handle HVAC as part of new construction, ADUs, additions, and whole-home remodels, as well as standalone system replacements and repairs.
New central air installation or replacement of an aging system. We size the unit correctly for your home’s square footage and insulation — an oversized system short-cycles and wastes energy, an undersized one runs constantly and still can’t keep up on a 100°F Valley afternoon.
Furnace replacement, heat pump installation, and hybrid dual-fuel systems. With California’s building electrification push, we install a growing share of heat pump systems that handle both heating and cooling from one outdoor unit.
The most common HVAC solution for ADUs, garage conversions, and room additions that don’t have existing ductwork. Single-zone and multi-zone systems installed with no need to open walls for duct runs — a major advantage on older LA homes.
Leaky, undersized, or damaged ductwork can cut a system’s efficiency by 20-30% before the air ever reaches a vent. We inspect, seal, and replace ductwork as part of new installs or as a standalone fix for an underperforming existing system.
Diagnostic service calls, refrigerant issues, failed compressors, thermostat and control repairs, and seasonal tune-ups to keep an existing system running efficiently through LA’s long cooling season.
Rooftop package units, split systems, and ventilation for small commercial and tenant-improvement projects — retail, office, and light industrial spaces under 10,000 sq ft, coordinated as part of APLA’s commercial build-out work.
| System Type | Best For | Typical Cost |
| Single-zone mini-split | ADUs, additions, garage conversions, one room without ductwork | $3,500–$7,500 |
| Multi-zone mini-split | Whole homes without existing ducts, additions with 2–5 rooms | $8,500–$18,000 |
| Central air (existing ducts) | Homes with usable existing ductwork | $6,000–$12,000 |
| Full system + new ductwork | Older homes with no or failing ducts | $15,000–$40,000 |
| Heat pump (heating + cooling) | Electrification upgrades, gas-to-electric conversions | $8,000–$25,000 |

In most cases, yes. LADBS requires a mechanical permit for new HVAC installations, furnace or condenser replacements, and any work that adds or modifies ductwork. Like-for-like repairs to an existing unit typically don’t require a permit, but full system replacements do — and unpermitted HVAC work can create problems at resale. APLA pulls all required mechanical permits and schedules inspections as part of every installation.
California continues to incentivize the switch from gas furnaces to electric heat pumps. California Energy Commission-approved heat pump systems can qualify for state and utility rebates of $1,000–$3,000, and Title 24 energy code increasingly favors heat pump equipment on new construction and major remodels. See our guides to energy-efficient home upgrades and Title 24 compliance for more on what qualifies.
A ductless mini-split installation typically takes 1–2 days. A full system replacement with existing ductwork takes 1–3 days. A full install with new ductwork can take 1–2 weeks, plus permit and inspection time. We provide a specific timeline once we’ve seen your home.
Yes, for most LA homes. Winters are mild enough that a heat pump handles heating efficiently without a backup gas furnace, and the same unit provides summer cooling — one system instead of two, plus eligibility for state and utility rebates.
Yes. Ductless mini-split systems are the most common solution for older LA homes, ADUs, and additions without existing ducts — no need to open walls or ceilings to run new ductwork.
Yes. HVAC is designed and installed as part of the full scope on every APLA ADU, addition, and new construction project — sized correctly for the new square footage and coordinated with the rest of the mechanical, electrical, and plumbing work.
Yes. APLA Construction holds California Contractor License #1136359, which covers HVAC installation as part of general contracting work. We carry full liability insurance and workers’ compensation on every project.
APLA Construction provides free, written HVAC estimates for homeowners and property owners across Greater Los Angeles — whether it’s a single mini-split for a new ADU, a full system replacement, or HVAC for a commercial build-out.
