AC Installation
Professional installation of new air conditioning systems Professional service throughout the San Francisco Peninsula with same-day appointments available.
Direct answer
For AC installation on the Peninsula, the right quote should include load calculation, duct and airflow review, thermostat compatibility, equipment placement, and whether a heat pump is a better fit for the mild Bay Area climate. Replacing equipment by tonnage alone can create short cycling, noise, and comfort problems.
We schedule AC installation across the San Francisco Peninsula with same-day appointments and 24/7 phone support. To book a visit or get a diagnosis, call (650) 396-3290.
About Our AC Installation Service
Installing a new air conditioning system is one of the most important home improvement decisions you'll make. A properly sized and installed AC system will keep your Peninsula home comfortable for 15-20 years while operating efficiently and keeping your energy bills reasonable. We're here to help you make the right choice.
The first step in any AC installation is a proper load calculation. This isn't just measuring your square footage—it's a comprehensive assessment that considers your home's insulation, window placement, ceiling height, number of occupants, and local climate factors specific to your Peninsula location. Homes near the coast have different cooling needs than homes in Palo Alto or Mountain View where summer temperatures run higher. We calculate exactly what size system your home needs, avoiding the common mistakes of oversized or undersized equipment.
We offer a range of AC options to fit different budgets and needs. Traditional central air systems remain popular for whole-home cooling, while ductless mini-splits are excellent for homes without existing ductwork, room additions, or areas that need independent temperature control. Heat pumps are increasingly popular on the Peninsula because they provide both cooling and heating while offering superior energy efficiency in our mild climate.
Our installation team handles everything from removing your old equipment to installing the new system, running any necessary electrical upgrades, and ensuring proper refrigerant charge and airflow. We test the system thoroughly before we leave and walk you through the operation, including how to use your thermostat and when to change filters.
Every installation includes a warranty on our labor, and we help you register your equipment warranty with the manufacturer. We also offer maintenance plans to keep your new system running efficiently for years to come.
How We Think Through AC Installation
Old unit never cooled evenly
That is often a duct, return, insulation, or sizing issue. A new condenser alone may repeat the same comfort problem.
Home addition or remodel
Added rooms change load and airflow. The existing system and duct layout should be checked before equipment is selected.
No ductwork or poor duct access
Ductless mini-splits or heat pumps may be stronger options for rooms, garages, additions, and homes with limited attic space.
Electrical or thermostat limitations
Panel capacity, disconnects, thermostat wiring, and heat pump compatibility can affect the real installation scope.
Repair, Maintain, or Replace?
Load calculation before equipment choice
Oversized AC can short cycle; undersized AC can run constantly. The right size comes from the home, not just the old nameplate.
Ducts decide comfort
Duct leakage, undersized returns, and poor room airflow can waste a good installation.
Heat pump should be discussed
On the Peninsula, a heat pump can solve cooling and heating in one system when ducts, electrical capacity, and comfort goals fit.

Safe Checks Before You Book
List rooms that never feel right
The estimate should account for comfort complaints, not just equipment replacement.
Know your current system age
Photos of model plates, thermostat, condenser, furnace or air handler help narrow the planning conversation.
Ask what must change besides equipment
Duct sealing, returns, thermostat wiring, pad, line set, or electrical work can matter as much as the unit.
Do not open electrical panels, bypass safeties, vent refrigerant, or keep running equipment that smells hot, leaks water, or repeatedly trips protection.
