"True Air Mechanical is a very great company to work with. Pete our salesman was so very helpful, and patient with us. He was concerned about finding the right system and cost effectiveness for us since we are on a fixed income. He was not a pushy salesman and gave us time to do more investigation. Brian our installer was professional, perfectionist and such a pleasure to work with. He explained all aspects of the system. True Air recommended Carrier system, heat pump and ac unit."

"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."
