What is it that makes the experts at Greencat the “Jedi Masters” of residential energy efficiency here in Southern California? We are not your average HVAC or insulation contractor. Our team of home performance professionals are specifically trained, certified, and licensed to locate and fix the unseen “forces” that are hiding in your home, threatening your year round home comfort and energy efficiency. 

How do we do this? By testing your home using the most accurate home performance equipment available, and combining the results with proven home performance upgrades that will keep your home comfortable, healthy, and energy efficient. 

Ready (and Licensed) for Just About Anything

From the roof all the way down to the foundation, Greencat has the credentials to take care of your home comfort from top to bottom. Though we may specialize in the home performance upgrades that will make the greatest impact on your indoor temperatures and efficiency, like our attic insulation packages and installing whole house fans, we are also a licensed plumbing contractor, HVAC contractor, and general contractor. 

Californians Helping Californians

Why trust Greencat? Because we would never recommend a home improvement that we wouldn’t install in one of our own homes. We are a team of Californians looking to help other Californians. 

No two homes will ever be exactly alike. Even if two homes have the same floor plan, they’ve been lived in differently! Greencat is dedicated to finding home performance solutions customized to each home’s needs, so that you can experience:

  • Stable indoor temperatures, year round

  • Healthier indoor air through better ventilation 

  • Reduced heating and cooling costs

  • Fewer heating and cooling emergencies by reducing wear and tear
