The Palo Alto94301 calls we answer most often
If your system is doing any of the following, it is worth a diagnostic before the fault gets more expensive.
Short cycling — on and off every few minutes
Yellow or orange burner flame instead of steady blue
Breaker trips every time the system starts
No cool air, or air that is barely cooler than the room
Furnace lights then shuts down after a few seconds
Dead or bulging run capacitor on the condenser
Heating and air conditioning service built around Palo Alto
If your high-efficiency heat pumps and ductless mini-splits has started short cycling, blowing warm air or making a noise it never used to make, you are not alone — Palo Alto generates some of the highest call volume we handle in California. Inland valleys hit extreme heat while coastal zones stay mild, so system sizing matters more here than raw capacity.
Because California swings between seasons quickly, a lot of our Palo Alto calls come in the first hot or cold snap of the year — systems that sat idle for months and then get asked to run flat out.
If your system is over ten years old and you have had two repairs in the last two seasons, a replacement comparison is usually worth running even if the current unit still runs.

Palo Alto94301 HVAC questions, answered
Is my carbon monoxide risk something I should worry about?
With any combustion appliance, yes. A cracked heat exchanger can spill carbon monoxide into the living space, and it is odourless. We perform combustion analysis and a CO test on every furnace and boiler call in Palo Alto, and we recommend a working CO alarm on every level of the home regardless of who services your equipment.
Is my system low on refrigerant, or is it leaking?
Refrigerant does not get "used up" the way fuel does. If your charge is low, there is a leak somewhere — usually at a flare connection, a schrader core or the evaporator coil. We locate and repair the leak rather than simply topping up the charge, because a top-up alone will fail again.
How often should I change my filter in 94301?
Monthly inspection and replacement every 60 to 90 days is the baseline. Homes in Palo Alto with pets, ongoing construction nearby, or a high-MERV filter in an undersized return should move to monthly changes. A loaded filter is the single most common cause of frozen coils and failed blower motors.
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.
What brands do you service in Palo Alto?
All of them. Our 94301 technicians are trained on Lennox, Rheem, Mitsubishi Electric, Goodman 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 service commercial and light commercial properties?
Yes. Around Palo Alto we handle rooftop packaged units, split systems, VRF/VRV installations and building automation faults for offices, retail, restaurants and multi-tenant buildings, including after-hours scheduling so you are not disrupting trade.
