Before I called Brian I already had several quotes, but when Brian came to our house for an estimate I was certain that we wanted Brian to do the work and we stopped calling around. Nothing fancy to boast, Brain just game me the feeling that he had the knowledge, the qualifications and the experience to do the work well. He has a postgraduate degree from one of the best universities, and he is a licensed technician. Unlike many other people who try to sell as much as they can, Brian understood our needs. Even though he was very busy, he took the time to communicate with me via emails to make sure everything was ok before the installation. He also made arrangement for our free attic insulation work which was really not part of his job, so that every work was done in one busy day. Before the installation, there was a little surprise. But Brian absorbed the extra cost himself, so what we got in the end was added value to our already attractive deal. His company is lean, there is no extra admin costs and he can pass the savings to his clients. On the installation day, he and his team came at the time he said he would, our floor was well protected, and everything was cleaned up throughly when the work was completed. We are very happy with Brian and his team. They are knowlegable, skillful, responsible, trustworthy and at the same time they save us money. We highly recommend Mandarin Heating & Cooling. Thank you, Brian!
