Taking calls now·Speak with someone about your HVAC needs
Most of the calls we answer come down to two things: a house that won't cool, or a house that won't heat. Here's how we handle both.
Most air conditioner breakdowns trace back to one failed part: a weak capacitor, a burned contactor, a seized fan motor, or a slow refrigerant leak. We diagnose it with gauges and meters, not guesswork. Every repair comes with an upfront quote and an honest opinion on repair versus replacement.
Most furnace breakdowns come from a handful of parts: flame sensors, igniters, inducer motors, and control boards. We find the one that failed and fix it, usually in a single visit. We also check for the problems that matter for safety, like a cracked heat exchanger, and give you an upfront price before any work begins.
If something seems off with your comfort system, it usually comes down to one of these. Here are the problems we get called about most across San Mateo, and how we put a stop to each.
A system pushing warm air in summer is the call we run most. Our trucks carry capacitors, contactors, and motors to restore cooling same-day.
AC repairFrequent on-off cycling is the furnace protecting itself from a real problem. Ignoring it risks the heat exchanger, the most expensive part in the cabinet.
Furnace repairWeak airflow at the vents points to duct restrictions, a struggling blower, or high static pressure. A tune-up finds it before it kills the motor.
Maintenance & tune-upsA system past 12 to 15 years that needs a repair every season is telling you something. We'll give you the honest math on repair versus replacement.
System replacementIf some rooms get dusty faster than others, leaky or dirty duct runs are the likely cause. We inspect, clean, and seal what we find.
Air duct cleaningA garage office, a converted attic, or that one bedroom the ducts never reached, a ductless mini-split solves it without tearing open walls.
Mini-split installationA house at 90 degrees is an every-hour problem, so we treat it like one. Same-day appointments across San Mateo, with evenings and weekends available.
Experience is what separates a lasting fix from a temporary one. Our technicians have spent years reading these systems, refrigerant behavior, combustion, airflow, electrical faults, and matching the repair to the actual cause.
If a $40 capacitor fixes it, that's what we'll tell you. We quote repair and replacement honestly, with real numbers, and let you choose, no scare tactics, no pressure.
Lasting comfort comes from fixing the cause, not the symptom. We find why your system failed and shut that down for good, then back the work with a real guarantee.
For over a decade, San Mateo HVAC has been the trusted name for HVAC service in this part of CA. Our hometown technicians know the specific conditions that affect systems in this area, from the seasonal swings that work equipment hardest to coastal air that corrodes condenser coils.
Knowing San Mateo is half the job. We've learned which neighborhoods run undersized ducts, how the local climate loads systems season to season, and what inspectors here look for on permits, and we put that knowledge to work on every job so it's done right the first time.

Our 4-step process is designed for accuracy, speed, and zero surprises on the invoice.
Call (650) 220-0817 and we'll get you a price quote, often within a day. A few quick questions, cooling or heating, what the system is doing, how old it is, and we'll book a time that works for you.
We don't guess. The diagnostic covers the full system and turns into a straightforward recommendation with the cost spelled out up front.
Most repairs finish the same visit, our trucks carry the common parts. Replacements are installed to code with proper sizing, sealed connections, and clean workmanship.
We verify temperatures at the vents, check the charge, confirm the condensate drains clear, and walk you through what was done. Optional maintenance plans keep the system cleaned, inspected, and running efficiently for years.

Speed matters when the temperature is climbing or dropping. This is the sequence our team runs through, from the moment your call comes in to the moment your system is running again.
The first call is where it all starts. Someone on our team picks up, works out how urgent the situation is, and schedules the soonest visit available, while telling you the few simple things to do in the meantime.
There's no waiting around for days. A fully equipped technician pulls up to your home, often same-day, with the parts already on board to diagnose and start fixing right then.
The fault is pinpointed, capacitor, motor, refrigerant leak, control board, or the compressor itself. Right away, we fix it there and then whenever parts allow, or quote the replacement with real numbers if the unit is done.
Lasting comfort is the whole point. We verify the repair, note the system's age and condition, and offer a simple seasonal plan that keeps efficiency up, breakdowns down, and miserable nights off your calendar.
"We put a ductless mini-split in the bonus room over the garage that no vent had ever reached. They measured and calculated instead of eyeballing it, and the install was clean and quick. That room is finally usable year-round."
"The AC would run for hours and never hit the set temperature. Their tech pressure-tested the lines, fixed the leak, and weighed in the correct charge instead of just topping it off like the last guy. It has kept up through every heat wave since."
"Our restaurant's rooftop unit failed on a Friday with a full weekend of reservations booked. Their team had us cooling again before the dinner rush. They clearly understood what downtime costs a San Mateo business, and they came back the next week to fully service the second unit. Customer for life."
Good HVAC service comes down to doing the small things right. These are the commitments that earn San Mateo HVAC repeat customers and referrals year after year.
Real experience isn't optional on our team. It means every technician understands sizing, airflow, and combustion, works clean and safe, and explains the work in plain language at a professional level.
Effective doesn't have to mean oversold. We size systems honestly and install them to code with quality fittings and clean workmanship, so you get reliable comfort with minimal disruption to your household.
A maintained system simply lasts longer, and we'd rather earn your trust than sell you a condenser early. Every maintenance visit is thorough and documented. For older equipment, a $40 capacitor caught early can save a $2,000 compressor. Period.
From our home base out to the neighboring towns, our technicians are based close enough to respond fast wherever your home or business sits.
