If you're looking for an HVAC company that won't overcharge you, call All Air Masters. I had several companies look at my unit. Aliso Air, who originally installed it, did a poor job, which led to the issues I was having, and then quoted me thousands of dollars to fix them. Ace Heating & Air Conditioning also quoted thousands. All Air Masters fixed it for $159. Their technicians knew exactly what they were looking at, the customer service was excellent, and they didn't try to sell me anything I didn't need. This is what a well-run business looks like: fair pricing, honest diagnosis, and no charging customers for work that isn't necessary. They've earned a customer for life.

Frankie was very courteous and professional. I required a routine maintenance and have continued them every year since installing my air-conditioning unit. I highly recommend them for any of your air-conditioning or heating needs.

Robby and Rafael were the installers of our new heating and air conditioning system. They were excellent / timely in getting things done. Kept me informed on progress. Made sure everything was properly working / tested before leaving. Great work. I highly recommend All Air Masters.

We had our entire HVAC replaced including ducts. Rafael was the lead and he provide courteous, professional, exceptional service. The crew was courteous, knowledgeable, paid attention to details and kept us in the loop as the job progressed. The system works great, is so quiet and was very neatly designed and installed.

Fabian and his co-worker was on time very professional and friendly. They were quiet and did not make a mess. All Air Masters installed my entire HVAC system in 2014. Rancho Cucamonga code enforcement inspector praised their work back then and their work so far is still just as good. Highly recommend.

We had a problem with our home A/C. We called All Air Master out as they fixed our unit before. Frank Jr quickly diagnosed the problem and we are back up & running! Highly recommend All Air Master. All techs are professional and knowledgeable.

Great experience with both Eric (diagnostics, estimate) and Frankie (service technician) to get my AC running with cool air again. Reason for 4 / 5 stars - the system to call or text appointment notice did not work for me. Both times had to call and tech still arrived after the appointment window. Very inconvenient to plan around other appointment but worth the wait.
