Ductless
Ductless mini-split installation in San Diego County

“Amazing service. We just bought a new house and didn't know any history of our AC unit. We got a recommendation from a friend and called Gold Coast. They were fast and went above and beyond in all the services we needed. Absolutely checking back in with them before summer for a tune-up …”
“[The owner] provided maintenance on our package unit. He was quick to respond when we reached out. Service was thorough and he took time to explain the issue. Pricing was fair. I would reccomend Gold Coast Heating and Air!”
