I've tried for 2 months to get costing details of the parts and when it finally was received it looks like i paid 13% hst on all the parts twice. Not good.

Today I had the good fortune to have a Mackay technician diagnose and repair our pool heat pump…read more Dan Swords was able to diagnose a faulty voltage boost capacitor within minutes. I was so happy because I feared that many other complicated problems that would suggest I had buy a brand new heat pump. Dan also did a thorough cleaning of the filter, coil fins. The freon level was also checked, no leaks. Dan cleared any other issues that may have caused the heater to default, only having to replace the voltage boost capacitor. I am so happy to have had this level of professionalism! Thank you Dan Swords, you rock! Tom Bonic

Our furnace broke down and Mackay was able to send a technician almost immediately. He gave us…read moreseveral options for repair, but we ultimately decided that it would be more cost-effective to purchase a new furnace. Given the fact that we had no heat, they made all attempts to accommodate us by sending the salesman within 24 hours. The salesman spent a lot of time with us, ensuring that we had all the information we needed to make our decision, and the new furnace was installed the next business day. From the beginning to the completion of our association with this company, we found them courteous, professional, polite, and anxious to ensure that we were happy with their work. They left the site clean, and even came back when they realized they had missed one small aspect of the job. They all wore masks and we felt very safe with them in our home. We would highly recommend Mackay Heating and Cooling.

Unfinished Installation, No Follow-Up - Extremely Disappointed…read more We purchased and installed an air conditioner from Mr. Furnace, and unfortunately, the experience has been deeply disappointing. When we first spoke with the salesperson, we were told that someone named "Insto" would return within a week to complete the remaining work. However, as of today--more than a month later--nothing has been finished. The job site was left incomplete, as you can see in the attached photo, and no one has followed up or contacted us to schedule a proper finish. We've been left completely in the dark and feel abandoned. We trusted this company based on their reputation, but this level of service is unacceptable. We sincerely hope Mr. Furnace sees this and takes action--not just for us, but to ensure other customers don't go through the same frustrating experience.

Misleading, Unreliable, and Completely Unprofessional - Avoid This Company…read moreI hired Mr. Furnace Heating and Air Conditioning for a heat pump installation, and the experience was a disaster from start to finish. They caused significant delays, installed incorrect wiring, failed to take responsibility, misled me about legal action regarding an energy advisor they recommended, and ignored my concerns about my rebate. - Major Delays & Installation Mistakes: The installation was delayed for nearly three weeks due to missing parts. When they finally did the work, an ESA inspector found a serious wiring mistake, causing even more delays. I also had to personally identify a missing wiring element that their installers overlooked, which was an unacceptable level of negligence. - Failure to Take Responsibility: Despite their "satisfaction guarantee," they have refused to properly address these mistakes. Every complaint was met with excuses, escalation, and no real resolution. - False Promises & Misleading Legal Claims: Mr. Furnace recommended and scheduled an energy advisor, Sean Corcoran, for my audit, but he never completed it. When I raised concerns, their sales manager, Adam Bond, told me legal action was being taken against him--but I later found out this was false, with no updates or accountability. - Three Weeks Just to Get an Invoice! After my installation, it took me three weeks of constant follow-ups just to get a copy of my invoice with the heat pump's part numbers. Every time I asked, they claimed it was "escalated"--but nothing happened. I eventually had to drive 1 hour and 30 minutes to their office, where I met with General Manager Sean Picco, who finally provided the invoice. - Ignored Concerns About My Rebate: After assisting with the invoice, Sean Picco has ignored all my emails and calls regarding my concerns about the rebate. Instead of addressing my questions, he has been completely unresponsive. - Unfulfilled Compensation Promises: Manager Mark Heggs promised me $500 in compensation for the massive delays and mistakes. That's barely anything considering my installation cost over $30,000--but even that was never fulfilled. Just another empty promise from this company. And before they reply to this review with their usual "We will be reaching out" response--don't believe it. I have contacted them MANY times, and their tactic is to delay, deflect, and ignore. They do not actually follow through on fixing issues. If you've had a bad experience with Mr. Furnace, you're not alone!
