Many Californians won’t even pick a restaurant without reading a handful of customer reviews, so why would you trust an insulation and home performance contractor without reading a few testimonials?

At Greencat, we are not your average blow-and-go insulation contractor. We take the time to speak with our customers, to get a good sense of how we are doing and how we can serve them better. Take a look at what real Greencat customers are saying about their experience trusting us with their whole house fan installation, attic upgrades, and energy assessments throughout Riverside, Los Angeles, and San Bernardino counties.
