“We had an outstanding experience with Cabrillo Heat & Air and Plumbing, and I cannot recommend them highly enough. They replaced our entire home heating system and added a new filtration system, and the quality of the work was exceptional from start to finish. On the plumbing side, they were absolute lifesavers. They fixed a long-standing clog in our master bathroom that two other plumbing companies had given up on, leaving us without a working shower for over half a year. Cabrillo’s team was knowledgeable, persistent, and solved the issue when others couldn’t. The crew was extremely professional, respectful of our home and space, and clearly very experienced. As an added bonus, they flushed our water heater at no extra charge, which really showed their integrity and care for their customers. Special shoutout to Robert and Rodolfo, who worked on our heating system — they were fantastic to work with.

“During the coldest weeks of this (2026) winter, our heating system failed. I called Carol Flynn’s Maria, the angel who manages the office, and even though every technician was busy, she arranged to have her boss, Marco, come out that afternoon to diagnose and possibly fix the problem, which turned out to be unrepairable. He thoroughly explained our options and I chose to have the furnace replaced with an upgraded, 97% efficient Carrier furnace and a new digital thermostat with wifi capability. Marco gave us an extremely fair price for the new furnace. Luis and Eddie were extremely thorough and without being directed, they upgraded everything: the mounting to the studs, all the electrical wiring, switches, PVC flue and drain lines. They completely rearranged their schedules and came out on a Saturday, spending the entire day to help us out. And in the few days we were without heat, Marco went out of his way to deliver 3 space heaters so we could stay comfortable. As a long-time customer, I could not recommend Carol Flynn and it’s employees more highly. They are caring, organized, extremely skilled, neat and most of all, honest. This company is simply the best; don’t waste your time with anyone else.”

“Steve from Next HVAC was a nice guy and honest too. The furnace was getting an overheating error code the past 1.5 weeks. But when he came to diagnose the problem the furnace starting working again. Instead of charging me some fictitious repair fee, he just charged me the $70 diagnostic fee which was already disclosed upfront. The furnace probably started working again because I emptied the bucket of water where the HE condensate hose was going into a few days before Next HVAC's service call. A few years earlier Innovative Mechanical came to inspect the furnace and all their tech did was remove the condensate hose from the bucket and he ended up charging me $335 for being there 1hr 15 minutes. Next HVAC was at my house maybe 45-60 minutes. Safe to say Innovative Mechanical got their money but lost a customer forever while Next HVAC gained a customer that will be calling them the next time I need a furnace repair or replacement.”
