We have lived in Newmarket for over 25 years (in the same house as well) S R. Gillis has installed and serviced our air conditioning and furnace when we need anything to be done. Our furnace was over 30 years old and finally had to be replaced. Stan and his employees were so helpful during this time. The temperature was -17c and Stan was quick to drop off some extra heaters to help us through the cold couple of days while they were working to get everything up and running even with the limited working space in our 1886 cellar! I will definitely be spreading the word about how efficient this company is for any of there services!
Thank you Stan and your team!

In February 2022 my furnace stopped working. It definately has been a cold winter. I called T H Oliver as I had been a customer since 2004 when I lived in Aurora. Elise provided such amazing and caring assistance. Someone came out quickly to assess the issue. To make a long story short, they were able to replace my furnace in a short time. Wayne and Chad could not have been more helpful and efficient. I would highly recommend T H Oliver for all of your furnace needs!Read more
