Expert Heating & Cooling Solutions for San Francisco

For San Francisco residents, Brentwood HVAC is the way around every bad HVAC experience you've heard about: the vague quotes, the mystery invoices, the replacement pitch for a system that needed a $40 part. That's not how we work. A real person answers, a technician shows up on time, the diagnosis is explained clearly, and the price is agreed before any work begins. Repairs, installations, duct cleaning, and seasonal maintenance, all handled by seasoned technicians who know the area.

Complete Heating & Cooling Services for San Francisco Properties

Heating and cooling around here covers a lot of ground: older gas furnaces on the older streets, newer heat pumps in recent construction, ductless mini-splits in additions and converted garages, and packaged units on commercial buildings. Our team works on every one of those systems. We have years of field experience, and we know how the local climate, the housing stock, and local code affect the way equipment performs and fails.

Most homeowners we meet need one of three things: a repair, a replacement, or a seasonal tune-up. Repairs are usually straightforward: a burned contactor, a dirty flame sensor, a slow refrigerant leak, or a worn-out blower motor. Replacements get a proper load calculation, not a guess based on the old unit's tonnage, which keeps temperatures even and stops the new equipment from short-cycling its way to an early failure. Maintenance visits cover coil cleaning, a refrigerant charge check, safety control testing, and a static pressure reading, which does more than anything else to extend the life of your system.

For commercial property owners and managers nearby, we service the rooftop units, split systems, and makeup air and ventilation equipment that restaurants, retail spaces, offices, and multi-unit buildings depend on. We understand that a hot dining room or a freezing office means lost business, so we prioritize fast diagnosis, carry common parts on the truck, and schedule work around your operating hours whenever possible.

When Your System Fails in San Francisco

Call us with a problem and a real person answers, not a recording. The majority of calls get scheduled the same day or the next, and urgent calls, a dead air conditioner during a heat wave or a furnace that fails on a freezing night, go straight to the front of the line. We keep the process simple so you're not stuck waiting for a callback.

These are the problems that come up most when something breaks at home: an air conditioner blowing warm air, a condenser that hums but won't start, a furnace that lights for a few seconds and quits, a breaker that keeps tripping, an evaporator coil that has iced over, a condensate drain backed up into the furnace cabinet, or a thermostat that has quit. Nearly all of these trace back to a part we already carry: capacitors, contactors, igniters, flame sensors, universal control boards, and common fittings. You get the price before any work starts, with no surprises on the invoice.

If your AC has iced over, the best thing you can do before we arrive is switch the system off at the thermostat and set the fan to "on" so the coil can thaw. Running it frozen can flood the drain pan and strain the compressor. If a furnace is short-cycling or you smell something burning, shut it down at the switch and call (925) 205-6539. A few minutes of caution can prevent a much larger repair.

How San Francisco Homeowners Can Extend HVAC Life

Many mid-season breakdowns start with maintenance that never happened, and the habits that prevent them are easy. Swap your filter every one to three months, clear vegetation at least two feet from the outdoor condenser, and hose off the condenser coil once a year in spring. Then book a professional tune-up twice a year, one for cooling and one for heating, so our technicians can catch small problems while they're still cheap to fix.

How old is your system? Its age tells you a lot. With regular service, most air conditioners make it to 12 to 15 years, gas furnaces 15 to 20, and heat pumps 10 to 15. If your system is beyond that range and also shows higher bills, uneven temperatures, or frequent repairs, it's usually due for a planned replacement, and that's almost always cheaper and less stressful than an emergency replacement when the first heat wave hits.

Small problems don't stay minor for long. Take a weak capacitor: replacing it is a quick, affordable repair, but if it's ignored for a season, it can burn out the compressor, and just like that a minor fix becomes a full system replacement. That's why we encourage homeowners to save our number in their phone and call at the first sign of trouble. Catching it early saves money and prevents a miserable night.

Comfort Challenges San Francisco Homeowners Face

HVAC systems in this area face a familiar set of enemies. Hard-running summers push compressors and capacitors to their limits, and humidity and airborne grit slowly foul outdoor condenser coils, cutting efficiency years before the equipment should show its age. Dirty filters quietly starve systems of airflow, freezing evaporator coils in summer and overheating furnace heat exchangers in winter, a slow kind of damage most homeowners never see coming.

We also see the full range of component failures in local homes: capacitors that leave the outdoor unit humming but not starting, contactors with pitted points, cracked igniters and dirty flame sensors that lock furnaces out on cold mornings, slow refrigerant leaks that leave the house lukewarm by afternoon, and blower motors worn down by years of restricted airflow. The area's mix of older homes brings undersized returns, leaky duct runs, and rooms the original system was never designed to condition.

Every one of these problems is fixable, and most are far cheaper to address early. If your system is doing anything unusual, new noises, weak airflow, rooms that won't hold temperature, bills creeping upward, a quick diagnostic visit from our team catches the small problem before it becomes an expensive one. Call (925) 205-6539 and we'll take a look.

Why San Francisco Residents Choose Us

Brentwood HVAC treats this community like our own backyard, because it is. We show up when we say we will, we diagnose before we quote, and we put real numbers on both repair and replacement so you can decide with facts instead of pressure. Our technicians are seasoned on everything from 20-year-old furnaces to inverter heat pumps, our trucks carry the parts that actually fail, and our work is checked in every mode before we go. That's why neighbors here pass our number around.

Common Heating & Cooling Questions

Yes, we do both. We fix AC systems, furnaces, heat pumps, and mini-splits no matter who made them. If replacement is the better call, we handle everything: old equipment removal, a properly sized new system, a clean installation, and a full test of every mode. You'll have clear quotes for both paths before you commit.
Yes, we offer seasonal maintenance for homes throughout the area. The spring visit focuses on cooling: coil cleaning, a refrigerant charge check, capacitor testing, and airflow readings. The fall visit covers heating: burner cleaning, a combustion check, and safety control testing. Keeping up with both visits extends equipment life, heads off breakdowns in the middle of a heat wave or cold snap, and often pays for itself in energy savings.
Every quote comes before any work starts, so you know the price up front. As a general range, typical repairs cost $150 to $650 depending on the part and system, and complete new systems run about $5,000 to $12,000 installed based on size and efficiency. Your exact price comes from an on-site diagnostic at your home, and the price you approve is what you pay, with no surprise line items.
Fast. We cover the whole area with same-day appointments for most calls, and no-heat and no-cooling emergencies get top priority. Our trucks carry the most common parts, including capacitors, contactors, igniters, and motors, so most repairs are diagnosed and finished in a single visit. Call (925) 205-6539 and we'll give you an honest arrival window.
There isn't one magic number, but a few rules of thumb help. Most part failures on systems under about 10 years old are worth the repair. Past the 15-year mark, or after a failed compressor or cracked heat exchanger at any age, a replacement usually comes out ahead, especially with the efficiency gains newer equipment offers. We'll give you both numbers up front and let you decide, because we'd rather earn your trust than sell you a system early.
All major brands, including Carrier, Trane, Lennox, Rheem, Goodman, and York, plus ductless systems from Mitsubishi, Fujitsu, and LG. Our technicians carry universal parts that fit most units and can order brand-specific components quickly when a repair requires them.
For a lot of homes, yes. Ductless systems shine in additions, converted garages, sunrooms, and older homes that were built without ducts. The process begins with sizing each zone to the actual room, followed by careful placement of the indoor and outdoor units and a clean install of the line set, condensate drainage, and electrical service. If central air is the better fit for your home, we'll let you know.
Check the thermostat mode and batteries, the air filter, and the breakers for both the indoor and outdoor units. If the outdoor unit hums but won't start, or ice has formed on the refrigerant lines, shut the system off so the compressor isn't damaged and call us at (925) 205-6539. We'll get a technician moving your way right away.
