AEROSEAL Duct Sealing Services

Did you know that up to 40% of the air that’s supposed to come out of your vents is actually escaping through cracks and holes in your air ducts? This can cause your energy bill to go up and some parts of your home to be too hot or too cold.

It also means that dust, dirt, and things that cause allergies are getting blown around your home. Gross!

The good news is that we can fix it easily.

AEROSEAL uses intelligent technology to identify the precise extent of leakage in your system and pinpoint all of the gaps and openings – even those that are invisible and out of reach.

Our duct sealant formula is safe, non-toxic, and contains the same material used in chewing gum and baby pacifiers.

Moreover, our non-intrusive process takes just a few hours and entails minimal disturbance or cleanup, making it highly convenient. Our experienced Gainesville air duct sealing technicians are fully trained and certified and can answer any questions you may have.

Scott was just here for my six month maintenance and did a thorough job. He ensured I understood everything that needed to be taken care of. He was informative and very professional. Really appreciate his work.

Where do I start. First, I want to compliment the professionalism exuded by the staff of Mid Fl I have encountered along the way. Very good company to do business with. Second, Kosha and Jacob were very efficient they worked as a team and got the job done. They were tasked with removing my 11 yo system and replacing that system with a newer and more efficient one. Upon their arrival they were ready to start and got down to business. With little hesitation they were able to install my system and answered questions I had about the process. And they were very friendly. Jacob worked efficiently without interruption. He handled his part of the assignment with ease. While Kosha attended to the other part. I must say they are well oiled machine. I am so happy with the service I received and look forward to working with you guys again. So my 5 star rating is what I think of my service I received today. Thank you so much. If you need your system repaired, replaced, or maintenance you won't go wrong.

UPDATE: October 1, 2020

Today was my six month maintenance for my system. Robert was my technician and he was thorough with the process. He informed each time he thought it was necessary. Courteous and professional. I am very satisfied with my service I received today.

Why Duct Leakage Matters

Leaky ducts compromise your comfort, energy efficiency, and peace of mind. Imperfections such as cracks and holes in your air vents and ductwork enable conditioned air to escape before it reaches its intended destination. Even brand-new duct systems may appear professionally installed, but each metal-on-metal joint that hasn’t been adequately sealed represents a potential leakage point. Consequently, you’re left with stuffy, uncomfortable rooms and higher energy bills due to wasted air.

Leaky air ducts can result in:

  • Excessive dust in your home
  • Mold spores and other contaminants in your air
  • Minimal airflow due to leakage
  • Uneven room temperatures

Our fully licensed and trained HVAC experts use the AEROSEAL method to stop leaks. This method uses patented technology to put escaping air under pressure, causing polymer particles to stick to the edges of a leak, and then to each other, until the leak is sealed entirely.
