No games, no guesswork, just a fixed price and a technician who actually knows what failed — that's the whole pitch.
What you're actually getting when you call.
We do one thing in Potrero: HVAC repair and installation, done right the first time. Every technician on staff is licensed, background-checked, and EPA 608 certified to handle refrigerant legally — there's no gray area on that.
A recurring story from new customers: a phone quote that didn't match the invoice. So our pricing is flat and written down before a wrench touches anything, full stop, 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 say the cheap fix out loud, even when it costs us the bigger sale.

What we tell Potrero homeowners to watch for.
Refrigerant leak, failing compressor, dirty coil — all different fixes, all confirmed with a gauge before we quote anything.
Noise on startup is a clue, not a death sentence for the unit.
The system works harder long before it fails outright.
Either pattern wears down components ahead of schedule.
Standing water usually means a blocked drain line, worth catching early.
Ductwork is the usual suspect here, not the unit.
Usually mold or mildew building up in the ductwork or on the evaporator coil, worth addressing before it affects air quality.
Aging equipment tends to fail at the worst time — a proactive look can flag whether replacement planning makes sense.
Certain smells mean stop running the system and call, not wait and see.
Ice on the condenser in cooling season points to airflow or charge problems, not something to just wait out.
Sticky air despite a cool thermostat reading usually means the system isn't running long enough to pull moisture out.
The full scope of Potrero work we take on.
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.
The approach doesn't change based on the size of the job — test first, quote second, always.
Downtime costs businesses money, so commercial accounts get moved to the front of the line.
Beyond heating and cooling, we handle the air quality side too — purification, humidity, filtration.
Seasonal maintenance catches small issues before they become expensive ones, which is almost always the cheaper path.
Duct problems quietly waste money long before anyone notices, and we test and seal as part of a full evaluation.
Smart thermostat installs start with a compatibility check, not guesswork.
Heat pumps get their own diagnostic approach, not treated like a standard split system.
Sizing starts with an actual calculation, so the new Potrero system performs the way it's rated to.
Real measurement tools replace guesswork on comfort complaints.
Rooftop equipment gets the same careful approach as anything else we service.
