Why I Started CMG
After spending more than 25 years in the HVAC industry, I saw the same problem every single summer.
Homeowners would spend thousands of dollars adding air conditioners to their garages, add insulation, or try to solve comfort issues, yet one of the biggest sources of the problem was often ignored—a superheated attic or garage.
I’ve been in thousands of attics and garages across Arizona. I’ve seen temperatures well over 150°F, technicians struggling to work safely, ductwork baking in extreme heat, HVAC systems forced to work harder than they should, and garages that homeowners can’t use in the summer. Time after time, I found myself asking: “Why isn’t anyone solving this?” That’s why I started CMG.
Our mission isn’t simply to sell fans. It’s to Protect People, Protect Homes, and Protect Things that matter most with affordable, dependable, easy-to- install solutions.
Thank you for trusting us. We look forward to helping you “Beat Attic & Garage Heat”.

I love my G14 garage fan. I live in the Phoenix metro area and when it gets over 110 degrees on a sunny day my garage can get to 130 degrees. I bought my fan in May of 2012, and since I installed it, my garage temperature is comparable to the temp outside in the…

Frequently Asked Questions
Find quick answers to common questions about our fans, installation, and performance.
What is an AGF-14?
The AGF-14 Attic & Garage Ventilation Fan keeps your garage and attic cooler. It’s designed to mount in the ceiling of the garage, venting to the attic. The fan will turn on automatically via a thermostat and pull fresh air into the garage and exhaust into the attic pushing the superheated air through the existing attic venting. The AGF-14 Attic and Garage Fan will cool the garage as much as 20 degrees and the attic as much as 40 degrees.
How does an attic & garage fan work?
The AGF-14 works by pulling cooler, fresh air through the intake vents in the garage and exhausts the air into the attic. The fan then forces the super-heated attic air out the existing attic vents, which may include gable vents, ridge vents, dormer vents, whirley vents, etc. A built-in thermostat allows the AGF-14 to automatically activate for their particular climate or season.
What type of fan do I need?
- AGF-14: Ideal for homes with an attic above the garage. Designed to remove the heat trap from both your attic and garage.
- AF-14: Specifically designed for homes with attic spaces. This fan has multiple mounting opinions including; gable, dormer vent, whirley bird, etc.
- SWGF-14: This is a sidewall ventilation fan designed for homes that are 2-story, flat roof, or no attic space above the garage. Also suitable for stand alone garages, sheds, or any other closed space that needs ventilation.
