The staff at Mr. Furnace were very good at hearing me and offering solutions.
McKenzie, the admin person was very understanding, helpful and kind. When I suggested a solution, she was very receptive and thankful.
The sales guy, Vince was also very sorry for all my troubles and was also very amenable to my solution.
Finally, I think my interactions with Mr. Furnace will improve somethings and the company will benefit for the future.

UPDATE:
So, McKenzie, the admin person called me to apologize. She was very understanding and offered me a better deal to make up for the disappointment.
The new heat pump arrived this morning.
IT DID NOT FIT INTO THE ALLOCATED SPACE!!!!!!
So, I still do not have a heat pump and I am even more disappointed.
Not sure how this company got the good reviews.
----------------------------------------------------------------------------------
I called Mr. Furnace in St. Catharine's on the advice of a local contractor, who suggested that this company may have a product that suits my needs.
Their representative, Vince, came the next day and explained the heat pump to me and how it would work for my situation. So, I decided to buy a heat pump.
Vince informed me that I was expected to pay in advance and that they preferred I pay by cheque, so I wrote a large cheque and Vince booked the installation for today.
Yesterday I received an electronic message reminding me of the installation today. It stated that the technician would arrive "between 8:00 am and 12:00 pm".
This morning I got up early to make sure to be up when the technician arrived. I moved my car so that they would be able to park in the driveway and I removed items from the work zone. I received another confirmation that the technician would arrive as stated. I confirmed and received notification of the confirmation.
NO TECHNICIAN HAS COME TODAY AND NO ONE HAS CONTACTED ME. NO HEAT PUMP HAS BEEN INSTALLED!!!
So much for all the great feedback from customers. I am beyond disappointed.
I expected much better from this company, based on the feedback. So here is min
I had an amazing experience with MR Furnace. From the very first phone call to book the appointment, everything was smooth, professional, and well organized. The entire team was friendly, responsive, and a pleasure to deal with.
Our technician, Rob, was fantastic — punctual, knowledgeable, and incredibly honest. He took the time to explain everything clearly, worked efficiently, and most importantly, never tried to upsell or push unnecessary services. It was refreshing to deal with someone who genuinely cared about doing the right thing rather than selling extras.
The service was fast, helpful, and stress-free from beginning to end. I couldn’t be happier with the experience and would absolutely recommend MR Furnace to anyone looking for reliable, honest, and professional service.
Highly recommended!
Luckily, I had the privilege of having Claude come out to my first call, and I'm forever grateful for it. Claude has the brilliant balance of professionalism and personality that makes him stand out by far. Always kind, friendly, and open to explaining and answering questions; not to mention being tremendously knowledgeable, skilled, and determined to get to the root of an issue and fix it.
It's a true relief knowing that they are available to keep my home comfy & cozy all year round.
Bryan did a great job replacing a part on our furnace. He also completed the regular fall tune-up for the furnace aswell. Friendly and very polite.
