"Trinity Heating installed a new thermostat in my house. The technician, Jimmy, was professional and courteous. After the installation he took the time to explain to me how to set up and use the new thermostat. I’m completely satisfied with their service and will use them again if needed."

"I have used Kyle twice now, and each time I was very pleased with the job of his handyman. I moved into a new home about a year ago that required multiple finishing touches, such as installing doorstops, bathroom cabinets, replacing trim, installing a ceiling fan etc. I recently used Kyle again for some ongoing maintenance projects. I found his price to be very reasonable, and the work to be high quality. Our handyman was Gregorio each time, and he is amazing! I would recommend Kyle's team to friends and family for sure."

"First off, Bernie is the owner and will be personally involved in your project. He has a wealth of experience and knowledge. I really appreciated how Bernie approached the project and how upfront he was about making certain changes and how they would affect the home cooling/heating situation, or the overall project success. He was very detailed in his approach and his inspection - the only one of the bids that I received that actually inspected the venting in the attic, rather than guessing by the age of the home. I HIGHLY recommend Bernie and Air ASAP and believe that this local & small business will continue to have great success in the local South OC markets!"

"I’m so glad I found Axis Team. Mack provided outstanding service. He completed chandelier installations, installed dimmer switches throughout the home, replaced broken the doorbell, fixed a leak, replaced a sliding door handle & lock and replaced broken locks on windows. On time, very responsive to texts, professional, pleasant, cleans up after himself, works very fast and has experience in all things you’d want in a handyman. Highly recommend!"

"Hired them to install a brand new unit, I am extremely satisfied."

"I have a tankless water heater that was giving an error code and i had no hot water! The tech that came out was very nice and knowledgeable. Im glad to report i now have hot water again. As a side note I talked with the tech about water treatment options and a RO system and as long as my husband agrees I will be having them install both items!!"

"Very knowledgeable, professional, and great customer service! Penguin, serviced our central AC & Heat and they explained everything to us before performing the work. They also replaced our moldy insulation in our attic. They packed and transported the old moldy insulations, ensuring that the mold does not spread, and they left our house free of any mess. I'd recommend Penguin Heating and Air to anybody in need of AC/Heat service, repair, or installation."

"The installer technicians came on time and did a good job. They were courteous and professional. I highly recommend this company for installation of new furnaces."

"Got a great product for the $$ I spent, the installers did a great job and were very professional and took the extra time to make sure my system provided adequate air supply to each of the registers in my home. Had on miscommunication on when the workers would show up, but it was handled and all is good."
