Who We Are

Not a Franchise Script — Just Millbrae Techs

The short version of who shows up at your door.

HVAC Repair CO isn't trying to be everything to everyone — we fix and install HVAC equipment in Millbrae and Millbrae, CA, and that's the whole business. Every technician on staff is licensed, background-checked, and EPA 608 certified to handle refrigerant legally — there's no gray area on that.

We got tired of hearing the same complaint from new Millbrae customers: the last company quoted one price on the phone and a different one at the door. The number we say is the number you pay, and that's true whether it's a $150 capacitor or a full system.

Referrals are how we grow here, so cutting corners isn't worth the reputation hit. We'd rather tell you a $200 fix solved it than talk you into a system you didn't need.

Know the Warning Signs

Six Signs Your Millbrae System Needs a Look

Catch these early and the fix is usually smaller.

WARNING 01

Warm Air From the Vents

Refrigerant leak, failing compressor, dirty coil — all different fixes, all confirmed with a gauge before we quote anything.

WARNING 02

Grinding or Squealing on Startup

A specific noise usually means a specific part — bearing, belt, motor mount — not a system that needs replacing.

WARNING 03

A Bill That's Climbing With No Reason

Dirty coils, low charge, and leaky ducts all quietly drive up runtime before anything actually breaks.

WARNING 04

Short-Cycling or Running Nonstop

Both extremes stress parts that are cheaper to fix now than after they quit entirely.

WARNING 05

Water Near the Indoor Unit

Standing water usually means a blocked drain line, worth catching early.

WARNING 06

One Room That's Never Comfortable

Ductwork is the usual suspect here, not the unit.

WARNING 07

A Musty Smell When the System Runs

A musty odor on startup points to moisture somewhere in the system.

WARNING 08

The System Is Older Than Fifteen Years

Older systems are worth a checkup before they force the decision.

WARNING 09

Strange Odors From the Vents

Certain smells mean stop running the system and call, not wait and see.

WARNING 10

The Outdoor Unit Is Covered in Ice

Ice on the condenser in cooling season points to airflow or charge problems, not something to just wait out.

WARNING 11

Rooms Feel Humid Even When It's Cool

Sticky air despite a cool thermostat reading usually means the system isn't running long enough to pull moisture out.

What We Do

Core Hvac Services in Millbrae

The full scope of Millbrae work we take on.

SERVICE 01

Emergency Repair

Total no-heat or no-cool gets same-day dispatch, day or night — a real person answers the line, not a voicemail loop, answered by an actual dispatcher, any hour.

SERVICE 02

Residential Repair & Installation

Single-family homes and Millbrae condos get the same diagnostic-first process whether it's a $150 repair or a full system swap — test first, quote second, always.

SERVICE 03

Commercial HVAC Service

Downtime costs businesses money, so commercial accounts get moved to the front of the line.

SERVICE 04

Indoor Air Quality Upgrades

Beyond heating and cooling, we handle the air quality side too — purification, humidity, filtration.

SERVICE 05

Preventive Maintenance Plans

Seasonal maintenance catches small issues before they become expensive ones, which is almost always the cheaper path.

SERVICE 06

Ductwork Sealing & Repair

Leaky ductwork in a Millbrae attic or crawl space can waste a large share of conditioned air before it reaches a vent, and we test and seal as part of a full evaluation.

SERVICE 07

Smart Thermostat Installation

A thermostat upgrade is one of the cheapest efficiency improvements available, and we check compatibility with your existing Millbrae system first, not guesswork.

SERVICE 08

Heat Pump Service & Repair

Reversing valve, defrost cycle, and auxiliary heat all need specific diagnostic steps a general repair call doesn't cover, not treated like a standard split system.

SERVICE 09

New System Installation

Sizing starts with an actual calculation, so the new Millbrae system performs the way it's rated to.

SERVICE 10

Static Pressure & Airflow Testing

Real measurement tools replace guesswork on comfort complaints.

SERVICE 11

Commercial Rooftop Unit Service

Rooftop equipment gets the same careful approach as anything else we service.
