About Us

My name is Glenn Welch President of Lake Simcoe Heating & Air Conditioning Ltd. I have been involved with Heating and Air Conditioning since the early 80′s. In 1994 I opened up my company Prestige Mechanical Ltd. We have successfully grown over the years and service the GTA and surrounding areas.

In the summer of 2008 I relocated from Toronto to Barrie, and it is at this time I would like to introduce you to Lake Simcoe Heating and Air Conditioning Ltd. We are a full service heating and air conditioning contractor available to you 24/7.

It is with the same principles which have helped Prestige grow successfully over the years I bring forward into this business venture. We offer honesty, reliability, and competitive pricing. We are committed to providing each of our customers with high quality products, services and solutions on time and within your budget at the best value for you. There is no job to big or too small. We have fully licensed and experienced technicians that can take care of any job, from installing a new boiler to replacing a thermostat.

Please consider Lake Simcoe Heating & Air Conditioning for any of the needs you might have in the future. We look forward to hearing from you.

Yours truly,

Glenn Welch, President
