Great Service!




Review of Westisle Heating & Cooling Ltd.

Dave was wonderful. This was our first servicing on our heat pump and we look forward to many more in the years to come. Dave was very patient with all of our “newbie” questions. I especially liked the efficient “check out” service using his iPad type device. A receipt was instantly delivered to my email and Dave offered a “notify of next service” option so that I will be contacted by West Isle when service is due again. Thank you very much for your professional and knowledgeable technician Dave. PS…Dave was great with our “yappy” dog too!;-)
