Los Altos HVAC questions, answered
What does a new system cost in Los Altos?
A complete residential replacement in the 94022 area generally lands between $6,000 and $13,000 installed, depending on capacity, efficiency rating and how much ductwork has to be modified. We always perform a Manual J load calculation first, because an oversized unit costs more to buy and runs worse than a correctly sized one.
What brands do you service in Los Altos?
All of them. Our 94022 technicians are trained on Carrier, Trane, Lennox, Rheem and essentially every other residential brand sold in California, including discontinued lines. We keep a broad parts catalogue on the trucks for exactly that reason.
Do you charge extra for nights, weekends or holidays?
No. Our pricing in California is the same at 2am on a holiday as it is at 2pm on a Tuesday. Emergency calls are dispatched the same way as scheduled calls and carry no overtime premium.
Do you offer maintenance plans?
We do. A two-visit plan in California covers a spring cooling inspection and an autumn heating inspection, priority scheduling during peak weeks, discounted repairs and no diagnostic fee. Members rarely end up on the emergency list.
Can you give me a price over the phone?
We can give you realistic ranges — and this page lists the ones homeowners in Los Altos see most often — but a firm price needs eyes on the equipment. Any company that quotes a final number without seeing the unit is usually quoting low to get through the door.
