I’m always anxious when looking into a company to do work for me because so many will take advantage of ones who do not understand the whole process of putting something so costly into a home like a heating system , A/C or whatever the house needs but I am so happy with Gillanders Heating for being patient with me and the work they did was fast and they were very professional, courteous, and came when called. They explained the process with me and I feel comfortable when they come to do a service check on my unit because they are very friendly and polite!! Thank you Gillanders!!

Called and received same day service, that was a surprise, I figured I would have to wait considering its “that time of year.” I was excited to at the prompt service and was given a narrow time if day so I didn’t have to wait at home all day. Dale serviced the system and was a professional. He explained in general terms (so I could understand) what was wrong and what he did to repair. He explained the cost and talked about a maintenance program. Overall a good experience. Thanks

Gillanders Heating was highly recommended to us by a friend and they did not disappoint. Had seasonal checkup and maintenance done on fireplace and furnace. Both technicians, Bill and Vince, were excellent! Very prompt, thorough, and professional. They were happy to answer any questions I had. Explained their final assessment findings. They made helpful recommendations without being pushy. Overall it’s been a great pleasure dealing with the Gillanders Heating team. They will continue to be our choice for all future maintenance and repairs.

I've used Gillanders Heating Ltd. since I built my home back in 1995. They have always did the yearly checkups for our furnace, A/C unit, hot water heater & fireplace. Vince & Bill are the technicians that know our equipment and always do thorough checkups. It is so nice to know that we are being taken care of by such a caring company. They are like family and if we need help they are right on it to make sure everything is running smoothly. I would highly recommend them to anyone who needs repair or new. Thank you to the Gillanders crew! - Jill Ellis
