3500 Sq-ft shop Heating

Member Posts: 1
Hey everyone,
I hope this is going in the right place, I own an Automotive repair shop in Toronto, it gets awful hot in the summers and winter it gets so chilled cold. So I want to put AC in the shop for my guys and the customer's cars. The issue is I am getting Estimates that are VERY far apart and the guys who come out to give the bids, don't seem very sure about what they are quoting. Recently I have been called by an industrial heating service. I haven't spoken to them until I get an opinion from you guys. The building is brand new, insulated very well on the sides and roof (Don't know what grade) 3500 sqft shop space, three roll-up doors, and 3 shop entrance doors. I currently have a 14' Big fan in the shop now. I've been told everything from a 5ton unit and if that doesn't work, they can add one more 5ton unit. Any thoughts or Ideas would be greatly appreciated so I can hopefully make an informed choice on who to go with.
Thank you!

I haven't check on this for several years, but the mechanical code in the U.S. used to require 100% fresh air if you used a ducted system to heat or cool an automotive repair shop. This is another reason why radiant floors are desirable for garages
Ductless units may be a way around this since ductless hanging heaters are allowed. I'd check with your code official and find someone whose COMPETENT to design it. A guy saying he'll put in 5 tons and if that's not enough he'll put in 5 more is not who you want.Bob Boan

A commercial garage should have a HVAC system that brings in outside air. https://www.engineeringtoolbox.com/garage-ventilation-d_1017.html
This is both for the comfort and health of your employees and customers.
Most manufacture reps have engineers on staff who are more than happy to assist with the design. Don't let the contractor guess at what is needed. Ask them to have the manufacture help get it right.
My guess is that a rooftop AHU is going to be the easiest way to accommodate your heating, cooling and ventilation needs

100% outdoor air would be a special unit made for heating & cooling that much outdoor air.0
