Join the Top Gun Club

A True Comfort Wonderland

Amazing things happen inside your home when you get treated like a VIP and the air in your home feels right year after year. And that’s exactly what happens in Green Horizon’s Top Gun Club. Grades get better, championships get won, your kids will thank you for all you do. And you’ll save lots of money too…

How You Save Way More Than it Costs

The 2 AC Optimizer visits we provide clean out the dust, dirt and debris that build up and choke heat and air systems. Clean systems have been proven to…

Last up to twice as long
Save you up to 25% on monthly costs
And eliminate 95% of all breakdowns

Adding up that savings alone more than doubles the cost of joining. But then you add…

Even More Discounts

15% discounts off repairs (if you ever have one) and any upgrades we suggest (covered by our Whole House Promise)
$100/yr toward replacement for every year you’ve been a member. The quicker you join, the more you save when it’s time to replace.
Free Diagnostics on any repairs, ’cause you’re family. Of course we’re coming out to find out what’s wrong for free.

Front of the Line Service

Whenever you need us, you’re guaranteed to move to the front of the line for service within 24 hours. Even if it’s super hot or cold, and everyone else is begging for service, we say yes to our family first.

Improving Your Home

On one of our Optimizer visits we’ll also do a home efficiency audit to see any ways that you could save money or improve your home’s comfort. Some of the things we’ll find you can do on your own for little to no money. Some would be things that we can provide. Either way, you’ll find out the way to make the most of your home’s efficiency.

For Veterans and Active Military…

We take care of your heat and air system for FREE. You’ve been willing to give the ultimate sacrifice to protect our country. The least we can do is make sure your home is a comfort wonderland. See the FREE benefits for Active and Retired Military…
