Frequently asked questions
How much does HVAC service cost?
Our $85 service call covers the diagnostic visit and is credited toward the repair when you approve the work. Most AC tune-ups run $90–$280 total after the credit. Thermostat installations and mini-split service calls typically fall in the same range. We give you a flat-rate quote before any work begins.
Can you come the same day?
Yes — about 70% of our HVAC service calls are completed same-day. For cooling emergencies in summer we prioritize quickly. Call (213) 205-2055 or text us a photo of your unit so we can bring the right part.
What brands and types of HVAC equipment do you service?
We service mini-split and ductless systems (Mitsubishi, Daikin, LG, Samsung, Pioneer), central AC condensers for tune-ups and refrigerant work, furnaces, and most residential thermostats (Nest, Ecobee, Honeywell, Emerson). Our EPA Section 608 Universal certification covers sealed-system refrigerant handling. Window and through-the-wall units are the one exception: those we replace rather than repair.
What warranty do you offer?
We warrant our repair labor for 30 days from the date of service. Parts we supply carry 90 days. Parts supplied by the customer aren't warranted, and the warranty doesn't cover components we didn't service.
Do you handle full system replacements?
Yes. We handle repairs and tune-ups directly, and for complete system replacements we coordinate the project through licensed HVAC contractors. You get one point of contact from diagnosis through completion — call us and we'll take it from there.
Can you repair my furnace the same day?
Yes — most furnace repairs (control board, blower motor, ignitor, flame sensor, pressure switch) are completed same day. We stock common parts. Our $85 diagnostic is credited toward the repair when you approve the work. Furnace repairs carry a 30-day labor warranty, and 90 days on parts we supply. Gas-valve and heat-exchanger work is arranged through our licensed HVAC partners.
Are you licensed and insured for refrigerant work?
Yes. Our technician holds EPA Section 608 Universal certification, which authorizes refrigerant handling on sealed HVAC and refrigeration systems. We are also California BEAR registered (#A 50636) and carry $1,000,000 general liability insurance.
