My garage is hot as !@#$. Last night I was dripping sweat just putting a front suspension on. Plus my beer fridge is working overtime. :omg: I'm looking into a wall installed exhaust fan. Any suggestions on models and CFMs and all that bs. Also, around the corner is cold weather and then the garage is cold as !@#$. Ceiling mounted heating units?

For's a tight three car garage.

what about a whole house fan. I doubt it would have done anything about the humidity yesterday/today but crack the doors and turn that Bad boy on for air flow. PS I know nothing about heating or cooling but my attic fan works good to vent the heat.

If you are going to heat and want to cool as well, look into a ductless mini split system. Get one that has the heat pump and it will do both. The cost of these units are not as much as you might think and are quite easy to install.

The ductless splits work good for cooling but if you don't have a good tight garage it will struggle during real cold weather as they loose capacity as the weather gets colder. For heat only, an LP Gas Unit Heater works well. You need to have a decent size tank for reliability during cold weather as small tanks will loose pressure once drained down a bit when it is super cold and the heater will lock out. A 125 Gallon Tank is usually good. Pricing for a 2 car garage? For DIY Guys figure $800 for a Unit Heater and $1,500.00 for a ductless A/C Unit. Obviously more if you need to bring in trades. Myself, I have a hydronic unit heater in my garage that runs off the same boiler and loop that heats the house. It costs just about the same as the LP Gas Heater but is most of the time only a good choice during new construction. The plan is to put a ductless split A/C in this Winter, if and when we slow down a bit. Here is a link below for a popular heater but you can buy locally from FW Webb or other supply houses. As far as ductless splits, stick go to the good ones. There is a lot of garbage out there. Mitsubishi, Sanyo, and Fujitsu are brands we use but Mitsubishi is by far the market leader. Anybody looking for any help in this area PM me your specifics and I'll see if I can head you in the right direction. ... P&addons=y

This will keep you toasty... doesn't help with the cooling. ... 2252256718
