Bay Area HVAC Repair You Can Count On
The Bay Area's microclimates put unique demands on HVAC systems. Coastal fog, inland heat waves, and year-round temperature swings mean your heating and air conditioning equipment works harder than average — and needs expert care to stay reliable. Our technicians specialize in HVAC installation and repair for every system type — residential and commercial: central AC, ductless multi-zone mini-splits, heat pumps, furnaces, boilers, and commercial rooftop units.
From a complex multi-zone install in a Walnut Creek estate to heating and air installation in a San Francisco Victorian or a rooftop package unit on a commercial building, we've seen it all. Every job starts with a thorough diagnostic, not a guess. We explain what's wrong, what it costs, and what your options are — then we do the work right the first time.
HVAC System Types We Install & Service
Split Systems
The most common setup in Bay Area homes. A split system pairs an outdoor unit — compressor and condenser — with indoor units that include an air handler. Refrigerant circulates between the two to deliver cool air in summer and warmth in winter. Split systems work with existing ductwork or as ductless multi-zone mini-splits, with multiple indoor units independently controlling temperature in separate rooms or zones — a common request in additions, ADUs, and multi-tenant commercial spaces.
Heat Pump Systems
Heat pump systems move heat rather than generate it — making them among the most energy-efficient options available. In summer they function as a standard cooling system. In winter they reverse the cycle to pull warmth from outdoor air. Because heat pumps run on electricity and reduce energy consumption compared to a gas furnace, they're a strong choice for California homes focused on lower utility bills and cleaner energy.
Package Units & Package Systems
Package units consolidate the compressor, air handler, coil, and sometimes a gas furnace into a single outdoor cabinet. Package systems are ideal for homes without attic or basement space for separate indoor equipment — a common constraint in older Bay Area construction and commercial buildings. We service all major package unit brands and configurations, from rooftop commercial units to residential slab-mounted systems.
Gas Furnaces & Air Handlers
A gas furnace remains the most common heating source in Bay Area homes with natural gas access. Paired with a central cooling system, it delivers fast, reliable heat on the coldest nights. The air handler is the indoor component that distributes conditioned air through your duct system — keeping it clean directly impacts indoor air quality and overall heating ventilation and air conditioning efficiency.
Indoor Air Quality & Energy Efficiency
Indoor Air Quality
Poor indoor air quality contributes to allergies, asthma, and chronic fatigue. We install filtration upgrades, UV air purifiers, ERV (energy recovery ventilator) systems, and ventilation improvements that reduce particulates and contaminants — delivering cleaner, fresher air in every room without sacrificing energy efficiency. We assess your current system and recommend only what your home or business actually needs.
Energy Efficiency & Energy Consumption
A well-maintained HVAC system uses significantly less energy than a neglected one. Sealed ductwork, regular tune-ups, and modern equipment reduce energy consumption and lower monthly utility bills without sacrificing comfort. We help you understand where your system's efficiency losses are before recommending any upgrades.

HVAC Work We've Done
FAQs
It varies a lot depending on what's needed. A routine tune-up is very different from a full system replacement. We don't give ballpark numbers over the phone because they're rarely accurate. We come out, assess your system, and give you a clear written estimate before any work begins. You'll know the full cost upfront.
