"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 recently had the pleasure of working with SoCal Boys Heating and Air Conditioning, and I couldn't be more impressed! From the moment I called for an appointment, their customer service was exceptional. The staff was friendly, knowledgeable, and eager to assist. The technician (Gerry) arrived on time, equipped with everything needed for the job. He took the time to explain the issues with my HVAC system and provided clear options for repairs and maintenance. I appreciated his honesty and transparency—there was no upselling or unnecessary pressure, just genuine advice tailored to my needs. The repair process was quick and efficient, and I was pleasantly surprised by how reasonable the pricing was. My system is now running better than ever, and I can already feel the difference in my home’s comfort level. What stood out most was their commitment to customer satisfaction. They followed up a few days later to ensure everything was working well and that I was happy with their service."
