Two systems do most of the work in a typical home, and they're the two we repair most. Here's what to expect when you call.
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. Pricing is upfront, and we'll tell you honestly whether a repair is worth it on an older unit.
A furnace that won't light on a cold night can't wait until morning. Most no-heat calls come down to a dirty flame sensor, a failed igniter, or a blower motor, and our trucks carry the common parts to fix them on the spot. You'll get a clear quote first, plus a safety check of the combustion and venting while we're there.
Wondering if it's bad enough to call? These are the most common heating and cooling problems we handle in homes across the area.
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 repairThat slow decline in performance isn't age, it's neglect compounding. A proper clean-and-tune brings most systems back to spec in one visit.
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 replacementDust settling everywhere within a day of cleaning, musty odors when the system kicks on, or allergy flare-ups indoors all point to the ductwork.
Air duct cleaningAdditions and bonus rooms rarely get enough duct capacity. A dedicated ductless head fixes the problem permanently.
Mini-split installationMost repair calls are diagnosed and fixed in a single visit because we stock the common parts, capacitors, contactors, igniters, motors, on every truck.
The person at your door knows HVAC inside and out, from superheat readings to error codes, because we hire seasoned pros and keep them sharp on the methods that actually work.
We treat your budget like our own: fix what's fixable, replace what isn't, and size every new system to your home instead of the biggest thing on the truck.
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 12 years, Daly City HVAC has been the go-to team 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 the code requirements local inspectors actually check.
Knowing Daly City 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.

From the first call to the final airflow check, our method is built to solve the problem completely the first time.
Call (650) 220-0819 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.
A technician evaluates the unit on-site, confirms exactly what's wrong, and lays out a plan and a price before any work begins.
Whether it's a ten-minute capacitor swap or a full system changeout, the work is done carefully, tested thoroughly, and left cleaner than we found it.
Before we leave, the system is tested end to end and your questions are answered. Seasonal tune-up plans are available to protect the investment.

A house with no AC in a heat wave gets dangerous, not just uncomfortable. Here's what our team does the moment you call to restore your comfort fast.
Our team answers your call right away, gathers the information we need, cooling or heating, running or dead, any error codes on the thermostat, and books your visit, often same-day. We'll guide you on switching the system off if it's iced over or short-cycling in the meantime.
Often within hours, our fully equipped technician is on-site with everything needed to handle the problem in your property.
The technician confirms exactly what failed and why, then fixes it on the spot, and if the system is beyond saving, walks you through right-sized replacement options with real numbers and a realistic timeline.
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.
"The AC would run for hours and never hit the set temperature. Their tech found a refrigerant leak at a valve, repaired it, and recharged the system properly instead of just topping it off like the last guy. It has cooled perfectly ever since."
"Our restaurant's rooftop unit failed on a Friday with a full weekend of reservations booked. Their team got it running the same day. They clearly understood what downtime costs a Daly City business, and they came back the next week to fully service the second unit. They've got all our locations now."
"Years of dust, pet hair, and who knows what else came out of our ducts. After the cleaning, rooms that never got air finally do, and my wife's morning allergies have all but disappeared. They showed us before-and-after photos of everything they pulled out."
Your home runs on this equipment every single day. Here's what sets us apart from other local service companies.
The difference shows up in the results. Our technicians have logged real years on these systems, so they identify the actual fault the first time and fix it properly instead of throwing parts at your system until something sticks.
We match every replacement to an actual load calculation rather than defaulting to whatever's on the truck. Installations get done to code: correct gas and electrical work, balanced airflow, and full commissioning. You get a system that performs for years, not just on day one.
Our team focuses on keeping systems alive with simple, scheduled care. If you want years more from your current equipment, our seasonal tune-up plans clean coils, verify the charge, and test every safety control. It's that simple. This approach is why so many homeowners recommend us.
Wherever you are in our service area, we've got it covered, with fast repairs, quality installs, and maintenance plans reaching every community on our list.
