Thermostat reading several degrees off from reality

Heating and air conditioning service built around Palo Alto
Homeowners across Palo Alto call us when the system simply will not keep up. Inland valleys hit extreme heat while coastal zones stay mild, so system sizing matters more here than raw capacity. That is why we staff a live dispatch line around the clock instead of routing you to a queue.
In the 94309 area we see a lot of attic-mounted air handlers. Attic heat soak in summer and cold-soak in winter both shorten component life and make insulation checks part of a proper diagnosis.
Peak cooling demand here runs May through October. Booking a tune-up in early spring means you are not competing with the whole neighbourhood for a tech in July.

Palo Alto94309 HVAC questions, answered
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.
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.
Why is my system short cycling?
Short cycling in Palo Alto most often comes from a restricted airflow path — a loaded filter, a closed register, an undersized return — or from an oversized unit. It can also be a failing flame sensor or a pressure switch fault. We measure static pressure and temperature rise before concluding anything, because guessing at this one is expensive.
What does a new system cost in Palo Alto?
A complete residential replacement in the 94309 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.
How quickly can a technician get to Palo Alto?
For the 94309 service area our target response time is 60-90 minutes from the moment dispatch confirms your address. Real-world timing depends on the day — the first sustained heat or cold snap of the season is always our busiest period — but we hold technicians locally specifically so that window is achievable rather than aspirational.
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.
