“Our Carrier condenser died on a 98° day. RO had a tech in Pleasanton within the hour, diagnosed a failed capacitor, and we were cooling again before dinner. Clean, honest, fair.”
Monica T. · Pleasanton, 94566 · Jul 2025
“Sub-Zero built-in stopped cooling the freezer side. Two other companies didn't want to touch it. RO's tech knew the unit cold, sourced the OEM part the next morning, done.”
David L. · Burlingame, 94010 · Mar 2025
“Replaced our 20-year-old furnace with a high-efficiency heat pump. Crew pulled the permit, cleaned up every day, and the Tri-Valley rebate paperwork was handled for us.”
Priya & Sam · Dublin, 94568 · Nov 2024
“Washer was leaking all over the laundry room floor. Booked online at 9am, fixed by 1pm. Price matched the estimate exactly.”
Renee K. · Berkeley, 94703 · Sep 2025
“Thermador double oven — control board out. They quoted, ordered, installed, and tested the self-clean cycle before leaving. Professional the whole way.”
Arthur M. · San Mateo, 94402 · Feb 2025
“Called three places. RO was the only one that told me my 17-year-old AC wasn't worth fixing and walked me through heat-pump options with real numbers. Zero pressure.”

06 · FAQ

Questions we hear every week.

Don't see yours? Call the line for your area and we'll answer it straight.

Do you offer same-day HVAC repair in the East Bay?

Yes. Requests placed before 2pm in Hayward, Berkeley, Oakland, San Leandro, Castro Valley, Union City, Fremont, and the Tri-Valley are almost always serviced the same day. Peninsula same-day depends on route — we'll tell you on the call.

Which brands do you service?

Every major residential brand: Carrier, Trane, Lennox, Rheem, Bryant, Goodman, York, American Standard, Mitsubishi, Daikin, Fujitsu, LG, Samsung, Bosch, Miele, Sub-Zero, Wolf, Thermador, Viking, GE Monogram, KitchenAid, Whirlpool, Maytag, Frigidaire, Amana, Kenmore, Electrolux, Speed Queen, Asko, Fisher & Paykel, Dacor, Jenn-Air, and more.

What's your service area — and what do you not service?

We serve the East Bay from Berkeley south to Fremont, the Tri-Valley (Dublin, Pleasanton, Livermore, San Ramon, Danville), and the Peninsula (Daly City to Redwood City). We do not service San Francisco, Marin County, the South Bay (San Jose/Santa Clara), or the East Bay north of Berkeley. Staying focused keeps our response time honest.

Do you charge for estimates or diagnostics?

We charge a flat diagnostic fee that is fully waived when you approve the repair. You'll get a written, flat-rate estimate before anything is taken apart.

Are your technicians licensed and insured?

Yes. Every tech is EPA 608 certified for refrigerant work, NATE-trained for HVAC, licensed in California under CSLB #1094021, and we carry $2M liability plus workers' comp.

What warranty do I get on the repair?

90 days on labor and 1 year on OEM parts we install. Full installations (heat pumps, furnaces, AC) carry manufacturer warranties we register on your behalf.

Do you work on commercial equipment?

Light commercial only — small offices, retail, restaurants with residential-class equipment. Rooftop units larger than 10 tons are referred out.
