Frequently Asked Questions

Menlo Park (94025), Atherton (94027) and Portola Valley (94028), plus West Menlo Park and Ladera next to them. If you are not sure whether your address is covered, call (650) 567-5385 and ask.

Monday to Friday 7 AM to 7 PM, Saturday 8 AM to 5 PM and Sunday 9 AM to 3 PM. Urgent calls are taken outside those hours too.

Yes. Urgent no-heat, no-cooling, gas-odor and breaker-trip calls are taken 24/7. Call (650) 567-5385 rather than booking online when something is failing right now.

No heat in cold weather, no cooling during a heat spell (especially with older people, small children or someone with a health condition at home), a gas smell, a burning smell from the equipment, and a breaker that trips again after you reset it. A slow drift in comfort, or one room warmer than the rest, can usually wait for a regular appointment.

Leave the house first. Do not switch lights or appliances on or off on the way out, and call the gas utility or 911 from outside. If a carbon monoxide alarm sounds, get everyone outside and call 911. Call us once you are safe.

Same-day service is available, but the schedule decides how soon a technician can come, so no arrival time is promised before the visit is confirmed. Tell us if it is urgent when you call.

Estimates for new and replacement systems are free: a new air conditioner, furnace, heat pump, central air or ductless system. Repair and diagnostic visits are not free, because finding the cause takes testing; ask about the visit fee when you book, including for a night or weekend call.

Yes. Before you approve a larger repair or an installation, you get the diagnosis, parts, labor and options in writing, and that work waits until you agree to it.

The system type (furnace, AC, heat pump or ductless), its approximate age, the symptom and when it started, and any error code. Photos of the data plate, the thermostat and the indoor and outdoor units help the technician arrive prepared.

The major heating and cooling brands, including Carrier, Trane, Lennox, Daikin, Mitsubishi Electric, Rheem, Bryant and York. We are an independent company and not affiliated with any manufacturer.

Compare the repair cost with the system's age, its refrigerant type, how often it has failed, its energy use and any comfort problems, and ask whether ducts or electrical limits would still hold it back after a repair. One failed part on a system that otherwise runs well usually points to repair.

Once a year for each system: cooling in spring, before the warm months, and the furnace in fall, before heating season. A heat pump works year-round, so some owners have it checked before each season. Check the filter monthly and replace it every one to three months, more often with pets, allergies or smoky days.

Yes. Ductless mini-splits suit additions, home offices, ADUs, older homes without ducts and rooms that need their own zone. The plan should confirm the room's load, where the indoor head goes, the line-set route, condensate drainage and clearance for the outdoor unit.

Often, yes. A heat pump heats and cools with one system by moving heat instead of burning gas to make it, and mild winters suit it well. The free estimate should check the home's heating and cooling load, the ducts, and whether the electrical panel has room for it.
