FAQs

Yes — Union City is part of our regular Bay Area service area. We install central AC, ductless mini splits, and window/wall units throughout the city, from neighborhoods near the BART station to homes closer to the hills. Call (408) 733-2000 to schedule a free on-site assessment.

Pricing depends on the system type, your home’s size, and whether existing ductwork can be reused. Rather than a rough number over the phone, we visit the property and put together a written, itemized estimate so you know the full cost before anything is scheduled.

It depends on what’s already in the house. Homes with intact ductwork usually do best with central AC, while additions, converted garages, or properties without existing ducts are a strong match for ductless mini splits, which skip that whole issue and let you zone rooms independently. We assess your specific setup rather than defaulting to one option.

Not long. A central AC replacement usually takes 4–8 hours, and a single mini split zone is often done in half a day, so cooling is back the same day in most cases. Projects that need new ductwork run closer to 2–3 days. We’ll confirm your exact timeline at the free assessment.

Often, yes — same-day repair visits are usually available if you call earlier in the day. Appointment slots fill up fast during hot stretches, so it’s best to reach out as soon as you notice a problem. Call (408) 733-2000 and we’ll check the soonest available time.
