Thermostat Installation Companies in Brea, CA

"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."

"Chris (owner) was great. He responded quickly to my inquiry for removing my under mount sink to install a new drop in sink and faucet and gave a free estimate. He was Punctual, knowledgeable, kind, answered all my questions and told me what supplies were needed. His employee Clayton completed the project and took the additional time to make adjustments to our countertop to ensure the sink fit properly and made sure everything was working correctly. He also cleaned up after completing the job. I am extremely satisfied with the workmanship and courteous manner of Authority Plumbing. Would definitely recommend."
