Hand holding an air duct and using a vacuum to suck out dust

Are your leaky ducts keeping your energy bills sky-high?

We’re here to help!


Schedule Service


A heart doesn't work without veins, a shower isn’t much good with leaky pipes, and your heating and cooling system will not be able to do its job well with poor ductwork! Even if your ductwork is leak free and brand new, design flaws can pose a hurdle to an efficient and comfortable home here in Los Angeles, Orange County, Western Riverside County, and Western San Bernardino County. 

In addition to specializing in the upgrades that will make your home more efficient, like insulation, air sealing, air conditioner replacement, and plumbing services, we can further increase the efficiency of those upgrades with our full range of duct services. Learn how these upgrades can affect how comfortable and energy efficient your home is.

Air Duct Replacement

Ductwork is notorious for developing leaks as it expands and contracts over time, and in a rush to finish the project (your home), contractors often install ductwork incorrectly. Plus, as your ductwork handles the air in your home, it can collect dirt, dust, bacteria, and other harmful indoor air contaminants.

Air Duct Sealing

How can you know if your air ducts are too leaky? With a scientific test we use at Greencat called a Ductblaster! This device allows us to accurately diagnose your ductwork leaks and seal them up properly from the get go. If you suspect your ductwork may be causing your high air conditioning costs, we’re here to help!

Full Home Weatherization

Leak-free, well-designed, properly installed ductwork is only one part of an efficient home. Weatherization—the process of preparing your home for the unique weather conditions it sees year in and year out—is another. Whether it is the Santa Ana winds or the Cathedral City heat, weatherizing your home with Greencat will ensure you are prepared for whatever the California weather has in store for you. 

Save Energy, Stay Comfortable!

Oftentimes, the home upgrades that can save you energy can also make your home more comfortable, but only if they are done right! Greencat is your trusted partner when it comes to making your home more comfortable while also reducing your energy costs and preparing for electrification. 

Do you suspect your ductwork could be affecting your comfort and indoor air quality? When it comes to ducts, we’ve got you covered. Call Greencat at 323-208-9071 or get in touch here.
