"It was over 90 degrees outside and the A/C was not blowing cold air. I called and explained it was for my 85 year old mother who was in home Hospice with end stage Parkinson's. I was worried she may get a heat stroke. They scheduled a service tech to visit in a timely manner. The service tech called an hour before the scheduled appointment to let me know he was on his way. Mark (service tech) was very professional and friendly. He not only got the A/C compressor to work but checked the Freon pressure and went in the basement to inspect the remainder of the equipment. He explained what might need replacing in the near future. Now I am not worried about my mother getting heat. I highly recommend this company for any heating and cooling repairs."

"Having already consulted with several HVAC businesses about repairing and updating my central air conditioning.. One that I had worked with previously-- but my satisfaction level wasn't that great and the others I was speaking to seem to be setting their rates rather high. So from several reviews and recommendation, I consulted with the SoCal boys.. And I am thrilled that I did. They were prompt, cordial, yet very professional-- respected my own knowledge. We conversed pleasantly then got down to it I was extremely pleased with their knowledge, openness and most of all their honesty! And their prices were more than fair! They knocked it out of the park! I would recommend them highly to just about anyone I know. They have my thanks and my respect!"
