As utility costs continue to rise and more homeowners add air-conditioning to their homes, the importance of having your home well insulated has never been greater.

What Our Customers Are Saying

"Work was completed in one day, and I could tell a difference almost immediately in the temperature in my home.

Air Conditioner doesn't run as much and my home is much quieter. Definitely worth the expense."

Jameson, Santa Ana, CA
"Our old house had no insulation. Thermal Advantage came out and insulated our entire house in one day. They even did it while we were out of town. We came back to a fully insulated home. All done thru the exterior and no mess inside the home. Would highly recommend."
Ashly, Oceanside, CA

"Great price, service, and results. I was able to get a quote over the phone and schedule quickly. I'm thrilled with the results and hardly have a need for air conditioning.

I wish I had contacted Thermal Advantage sooner."
