We are Extremely Satisfied

On or about Feb 25th, 2016 we had an American Standard Air Conditioner along with a Navien Tankless water tank installed. The installers were Richard and Mark. Every endeavour was made to keep our place clean and tidy during this process. 

On March 14th, Alex arrived to replace two ceiling fans and one light fixture with new ones that we had purchased. During this whole process, which was a major endeavour for us, we are extremely satisfied.
We do not hesitate to recommend this Company along with all its employees.

High Value of Service

Attn; Dave, Alex, Richard & Sean

Just a quick note to thank you for the great service you provided for the installation of a new American Standard furnace and running of a new natural gas barbeque line in our home.

From the first call to the final installation, everyone was punctual, efficient and professional. I also appreciated everyone’s patience when responding to my questions and concerns. Having managed service and installation departments in a similar industry, I fully understand the value of having quality (courteous, presentable, knowledgeable and efficient) service technicians. From what I encountered from Mainland Heat & Air Conditioning Inc., you’ve got some very good ones. Your prices were more than fair for the high value of service and installation you promised & provided.

I have no problem referring your company to friends, neighbors and family.

Highly Recommend

Thanks to everyone for a great install. We are very pleased with the knowledge and professionalism of the technicians who installed our a/c and new furnace. The cost for an American Standard system install quote was very reasonable, and we would highly recommend this company to anyone considering upgrading or replacing their existing equipment.
