"Aldo came to the job site the next day after we spoke by phone. He sent a quote for the work later that same day. He completed the project (replacing 2 gas wall furnaces) in a single day and the heaters were working that night. He was prompt, reliable and easy to work with. I highly recommend him."

"I am very pleased with the job Rudy and his associates have done. Rudy answered my phone call right away and that was quite impressive. He came to look at the heater next morning and carefully diagnosed the problem. He was concerned that I did not have heat in the house. Rudy and his associates started working right away and changed the heater. The heater was on in a few hours. I was relieved. Rudy was reasonable too. I would highly recommend him. Job well done!!

"Erasmo is great. He is very responsive. He came out right away, walked through the rooms that the furnace supplied heat to and recommended the size and replacement heater that was needed. We had three bids for this replacement heater and Erasmo was several hundred dollars less for the same project. The workmanship was quality and done in a timely matter. I highly recommend CaliforniAir Heating"

"Due to new construction in my neighborhood, over the past few years when we receive continuous or heavy rain there has been flooding under my house in my crawl space. After the first rain, I decided to install a sump pump system. Chris came out to look at the situation - he was knowledgeable, courteous and on time. The quote given was within the range of othre quotes given and was reasonable as compared to the services received. In other words, Chris did not try to cut corners in the quality of service in order to submit the lowest quote. The work is guaranteed and I was really comfortable with Chris' solution to my sump pump problem."

"They were quick and professional. The initial communication was a bit awkward with the company because their voicemail was full. But the work was awesome and the air conditioner is working again. I would hire them again."

"Called Trio Heating on a late Friday afternoon and they sent out two technicians (Jose & Dallin) the next morning to fix a gas heater that would not turn on. Their communication from beginning to end was great. They sent me a text 45 minutes before their arrival time and I was able to track their ETA which was extremely helpful. They explained to me what the issue was. I was able to run out and buy a new thermostat for them to install. They did a great job, cleaned everything up and put everything back together. They also typed up everything they worked on and took multiple detailed photos of the unit and emailed 10 minutes after they left. I think what they charged was extremely reasonable for the quality of work. I really appreciated not being charged a higher fee for coming out on a weekend. Will definitely use them again for my HVAC needs!"
