"Fontana Brothers installed my new Bosch HVAC system, and I couldn’t be happier with the experience. Freddie and Shaquille arrived exactly on time, worked efficiently, and left the work area cleaner than it was before they began. Their attention to detail and professionalism were outstanding. As a Realtor for more than 30 years, I’ve dealt with many HVAC companies, and Fontana Brothers continues to be one of the very best. They consistently deliver excellent service to both me and my clients, and their pricing remains highly competitive. I trust them completely with my referrals. Special thanks to Dan Fontana, who heads the service department — always organized, responsive, and helpful — as well as the entire office staff, who are consistently friendly and a pleasure to work with. I will absolutely continue to recommend Fontana Brothers to others seeking HVAC installation, repair, or replacement."

"Anthony was running a bit behind but called and told us he would be here after 5 pm. He did an outstanding job communicating and figuring out a difficult diagnosis to get my system up and running. He went above and beyond by helping to wrap my refrigerant lines that were deteriorating from age, he also cleaned the condenser coils while checking the system out. Very professional and friendly. also the lady that answers the phone is super nice every time I've ever called her. mostly after hours and of course this time was a holiday call. thanks Weathermakers!!"

"I had a great experience with hometown heating and air. The gentleman who came out was professional and very knowledgeable. I appreciated how he was able to explain what was wrong with my unit and I was able to upgrade to a new duct system. This was done in a timely manner as well."

"This Company is TOP NOTCH. I had about seven companies come to my home, none of which were of their caliper. They were responsive. Katie could not be MORE EFFICIENT, from set up to delivery. Greg Thomas and Axel.. came first. The Heads..were pleasant, SMILES that would cheer up ANYONE. They SAVED MY LIFE!!! From all the workers to the bosses could not have asked for a better company to come. Their vehicles were clean and nice their clothes were crisp and they all had great funny demeanor. The setup, installation, and clean up was remarkable. What great TEAMWORK ##1 . Being sick, they could not have come at a better time in my life. Thank you for all that you did/do each and every one of you.."

"My 16yo AC finally died and I needed a new system fast. I searched Angie's List, (I have had great vendors from here so far) and found West Coast Cold Air. The owner, Fernando, was very quick to respond. He came out that Tuesday to see what I needed and was able to install it Thursday am. He even gave me a loaner portable unit so we wouldn't melt another night without AC! He gave me a great price and he and his technician were in and out within about 3 hours. They are honest, fast, knowledgeable and easy to deal with. I would definitely use them again."
