With central heating and cooling systems, your home circulates air through a series of ducts from a central unit to all the rooms in your home.

Over time seals in the ducting break down and allow heated or cooled air to escape into space where it is not needed. Your natural tendency is to turn up the thermostat, which results in inflated energy bills.

By sealing leaky ducts in your home, the hot and cold air will be delivered efficiently to the space it is meant for. This means a warmer, more efficient home and lower energy bills for your family.


Some people say, “If it’s too good to be true, it’s too good to be true.” We can assure you that is definitely not the case with ESC’s free duct testing and sealing program.

A few years ago, ES Contracting approached our energy conservation specialist and proposed a program that tested and sealed ducts on manufactured homes in our service area. Extreme temperatures cause electric bills to skyrocket, and manufactured homes tend to have the leakiest duct systems, causing higher bills. Our program seeks to seal the ducts in as many manufactured homes as possible. So far this has been a massive success, having sealed the ducts in over 15,000 homes.

So, how do we offer this service?

“As manager of Mountain Vista MHC, I have all types of venders that walk into my office offering services to my residents, When Curtis arrived I figured free was too good to be true, boy was I wrong.

This company went above and beyond our expectations , while doing the home inspections and services, they were very professional. My residents have all been completely satisfied and happy with the work that was done and we are now getting the reports that their electric bills have been reduced so they are in the office thanking me.”

We work in partnership with your local utility company to optimize your duct system. Utility companies are required to reserve a certain amount of ratepayer money for energy efficiency programs. Duct sealing is one common program that many utilities implement, as having tight, leak-free duct systems delivers dramatically more efficient hot and cold air flow throughout the home. While many utilities require the customer contract the work AND THEN apply for a rebate, ES Contracting makes it easy by completing paperwork, performing the service, and receiving payment directly from the utility company, meaning less hassle and no out-of-pocket expenses for you, the homeowner.


While eligibility will vary somewhat depending on the specific utility company programs in your area, our focus is generally towards manufactured and mobile home customers. These types of homes have the highest rate of low-quality and leaky duct systems, which means the greatest energy savings is found from sealing.

Currently we have partnership with the following companies under their home efficiency programs:
