une 19, 2026, I contacted a company California Heating and Cooling by phone and requestes specifically for Mario. I selected him since his name was mantioned in many reviews, as an excellent expert. Mario came the next day, in the morning. At the end, Indeed, I was not disapponed. Opposite, I was thrilled.
Mario performed real checking of the whole cooling system including a compressor.. Mario localized mulfuction's parts and then exchaned them accordingly. Mario was very professinalanal, confident and knoweledge in electrical problems of the coolng system. The most important, he restored the whole system and make it to work again, the same day, in a few hours. I was impressed. Other consultants suggesed to exchang the whole system i.e. a furnace and a cooling system that usually costs from 21K to 28K. Others suggested to verify only a wiring system that is stil expensive ($750). I have mine system repaired for less. Therefore, Mario and also Mark, (even Mario admitted that Mark is very good in his profession) are persons whom you may trust. Mark was a second person to whom many reviewers reffered. Thanks to earlier reviewers for their honest evaluation of work performed and providing names of persons involved. It helped me a lot to in selecting a proper person. God beless all of you.

Air not working, called and got a next day appointment. Mark got here during the specified times I was given and he did a little troubleshooting and within 15 minutes my air was working again. Thank you, Mark!!
Everyone was friendly, helpful and efficient. Sam, who returned my call and scheduled my appointment and Mark who was the technician who diagnosed the issue with my HVAC unit. Unfortunately the part needs to be ordered, but the problem was diagnosed quickly and we have a plan. Thank you!
Job completed professionally. Mark, the technician, was very professional, great attitude, clear communications and trustworthy. Definitely will call on them again if needed.
Arrived within the window promised, diagnosed & fixed the problem to my AC unit in less than 5 minutes. Great communication including texts to advise they are on their way. Thanks guys!
