Your Orange County Neighbors Rely On Us,
For Fast AC Service
My AC recently went out and I had a company come out and told me that my AC was shot and needed to pay 15k for a new one. Needless to say I got a second opinion and called HVAC Alliance Expert. The tech arrived on time, wore booties, and fixed my AC for under $200. Huge thanks to HVAC Alliance Expert for keeping us cool and not breaking the bank!

Walsh just installed a window unit in my bedroom for half the price I was quoted by another company. He showed up on time, installation took 20 to 30 mins max, and he was incredibly professional and easy to work with all the way. He is very trustworthy; we would call him again if need be and will recommend this heating and air conditioning service to neighbors.
