Over 1,000 5-star reviews agree: Summers & Smith is the best choice for heating and cooling in York Region.

From the call centre to the sales staff, technicians and office staff, everyone I have dealt with at Summers & Smith have been great to deal with. I found the call centre very helpful in getting me started and setting up appts. The sales staff were honest, no up-selling or pressuring sales tactics.

Summers & Smith never disappoint! Their professional, friendly and knowledgeable staff are always a pleasure to work from the first phone call, to sales and of course their installation and repair team.

We have been using Summers & Smith for at least 20 years and have always had excellent service. David Tran serviced it this year and did an excellent job and offered excellent advice on how to extend the life of our furnace. Would recommend this company to anyone looking for 5-star service.

This is the best HVAC company I have ever dealt with. Front line staff are very friendly, courteous, and knowledgeable. Response time to breakdowns is fast and the technicians are very respectful and knowledgeable. They have gone out of their way to treat me very fairly under their warranty program and resolve the problems.
