We’ve been using Carlton-5 to service HVAC at our warehouse and office building in GTA for over 10 years.. They are very knowledgeable, honest and helpful. I rely on them almost exclusively for all our HVAC equipment service, improvements and related energy savings. Carlton-5 has never failed to deliver quickest response possible and excellent service. They are always on-time and on budget. I’ve been involved with Facilities Management for over 35 years and I can say with complete confidence – there are not many HVAC contractors who are this reliable and this trustworthy.

Carlton 5 Mechanical has proven to be both efficient and cost effective in moving our existing Condo buildings into a Energy focussed business. Working with our Board Members and Property management team to find solutions not repeated repairs that build excessive work orders. In addition to the mechanical services, Eric has introduced us to Nerva Energy which has been extremely instrumental in directing our reserves while educating us into the future. In our recent boiler replacement projects we were delighted to receive a large rebate from Enbridge due to Carlton’s forward thinking and initiative. We are happy to endorse and recommend this company and its professional and pleasant group of skilled and qualified team members where no job is too small or large.

Carlton 5 Mechanical Services provides us with fast and reliable excellent service. I can always count on Carlton 5 for all my HVAC repairs, service and new installations at fair pricing and prompt timing. There always available to assist and respond to any mechanical situations that are presented here at the facility.

My wife and I both thank you. Great job. Real Pros. Carlton 5 Mechanical Services replaced our furnace and A/C this year. Could not be more happy. Highly recommend calling Greg before you do anything.

Carlton 5 Mechanical Services saved us from the baking summer heat. Very professional and polite. Guys came when they said they were going to come. They really worked fast and cleaned it all up. So nice! Thank you so much for keeping us cool.
