Agricultural Aerosealing Duct Sealing for Energy Efficiency

The best way to make sure that your duct system is giving you as much heated or cooled air as possible is to have it thoroughly inspected and sealed with our agricultural Aerosealing technology. Here at Preferred Energy Consultants, we have the equipment and expertise to take on any Cedar Rapids, Iowa City, Quad Cities, Waterloo, IA surrounding areas, duct sealing job - no matter how large or how small.

What is Aerosealing?

The #1 reason farms want Aeroseal Duct Sealing is because they experience hot and cold rooms or temperature differences between upstairs vs downstairs areas. The majority of buildings we see suffer from these issues due to leaky ductwork not delivering conditioned air where it is meant to go! The agricultural Aerosealing simple, yet revolutionary process seals leaky ductwork from the inside – even the hidden ductwork that is behind your walls and otherwise unreachable!

On average, 30¢ of every $1 you spend on heating and cooling your building disappears into thin air due to duct leaks.

Benefits of Aeroseal Duct Sealing

Increase Your Comfort
Lower Energy Consumption
Improved Air Quality
Pre & Post Leakage Measurements

Duct leaks can be difficult and costly to find with ductwork hidden between the walls, floors, and ceilings of any building. Additionally, taping leaks is less effective and is also labor-intensive, expensive, and can only be applied to ducts with physical access.



The Agricultural Aerosealing Process

Step 1: Prepare Your System

Plugging your registers with foam forces the air in your ductwork to escape through leaks. By forcing air to escape through leaks we are able to pretest your duct system and begin the duct sealing process. How Aeroseal Works: Preparing your System A small access hole is cut into the supply or return and a temporary collar is attached. The air conditioning indoor coil, fan, and furnace are temporarily blocked with a foam plug to prevent sealant particles from entering this part of your system. How Aeroseal Works: Attaching the Collar The next step of the process is to pretest and inject non-toxic sealant into your ductwork. The pretest measures exactly how much duct leakage your system has in square inches and also calculates just how much air is escaping through leaks in your ductwork.

Step 2: Pretest Your Ductwork

Once the system is properly prepped the Aeroseal machine is connected to the ductwork using lay flat tubing. How Aeroseal Works: Pretesting your Ductwork The Air Duct Diagnostic pretest will detect the exact amount of duct leakage in the duct system – the typical duct leakage detected in a home is between 30-40%. Next, the non-toxic, UL tested and approved, an aerosol sealant is injected into your duct system. As the sealant exits your ductwork through leaks it begins to collect on the edge of the hole until the leak is completely sealed. Aeroseal can seal leaks up to 5/8ths of an inch.

Step 3: Seal Your Ductwork

Small aerosol particles are injected and kept suspended in the airflow by continuous air movement. How Aeroseal Works: Sealing your Ductwork The aerosol particles begin collecting on the edges of holes and cracks in your duct work and seal your leaky duct work from the inside. This entire process is computer controlled where you can monitor the results in real time showing you just how effective the Aeroseal process is. Ducts are sealed with only 1 to 2 oz. of sealant material.

Step 4: Review Your Results

A computer generated analysis summarizes your home’s duct leakage reduction providing you with verification of the success of the Aeroseal application. How Aeroseal Works: Before & After Sealing Once the process is complete your certified Aeroseal technician will provide you with a printed certificate summarizing your results.

Step 5: Enjoy Improved Comfort & Indoor Air Quality!

Now that you’ve had your ductwork sealed with Aeroseal you can expect to experience increased home comfort, improved indoor air quality, and lower energy bills!
