Did You Know?

Roughly 25% to 40% of energy is lost through the ductwork in homes that use ducted HVAC systems.

Frequently Asked Questions:

Q: What can I learn from the Air Duct Diagnostic and Inspection?

A: The inspection will help determine if there are any problems with the ductwork system. The Air Duct Diagnostic will show the precise amount of leakage coming from the duct system.

Q: What savings can you expect?

A: According to government reports, air duct sealing can permit up to $850 in energy savings annually. Some homeowners can actually save around 40% on their energy bill. Aeroseal air duct certified experts have the qualifications to run a program created by the Environment Protection Agency known as “Duct Investor”. This program takes into consideration a comprehensive list of variables, allowing the homeowner to have a good idea of how much they can save.

Q: In layman’s terms, how does an Aeroseal air duct seal actually work?

A: There will be a preseal test used as a baseline to measure progress. The registers must be blocked with foam or plastic. The UL tested and approved aerosol will be injected into the system. With no other places for the sealant to go, it will find duct holes or cracks and plug up the leaks. There will be a postseal test to check for all improvements with the functionality of your ducts. A full report and certificate will be printed showing the official record of improvements.

Q: How large can the holes be in the ducts that will be sealed by the Aeroseal air duct sealing process?

A: Cracks or holes up to 5/8th of an inch can be entirely sealed during this process.

Q: Does the air duct sealing material become weak or brittle?

A: The sealing material is vinyl with a rubbery texture and will never crack or break.

Q: How long can you expect the air duct sealing material to last after it is applied?

A: Through a rigorous testing process, we have come to find it will last a minimum of 10 years without failing.

Q: Should the ducts be cleaned before initiating the air duct sealing process?

A: In most cases, this is not necessary. However, your aeroseal contractor will let you know if cleaning is necessary for your particular situation.

Q: Will the inside of the ducts be coated with the sealant?

A: Only the holes in the ducts will be sealed by the sealant, it’s designed to stick to the holes to seal them properly.

Q: Is Aeroseal air duct sealing material safe?

A: The sealant is made up of approximately 65% water before it is applied. The dried material has two chemicals known as vinyl acetate polymer (VAP) and 2-ethyl-1 hexanol (2E1H). Most of what will be left in the ducts is VAP which has been used in all types of water-based paints, hair sprays, and certain adhesives. It has also been used in chewing gum and there is no OSHA Exposure limit for this particular chemical. 2E1H also is not considered toxic by OSHA. This sealing material is considered safe through rigorous testing.

Q: Is there an odor left behind from this sealant?

A: There will be no odors left behind for the whole life of the product.

Q: Can Aeroseal improve the performance of my HVAC equipment?

A: Aeroseal will help improve the performance of your HVAC considerably by stopping all the leakage and preventing energy loss.

Q: Can I expect lower energy bills with Aeroseal air duct sealing?

A: Most homeowners should expect to see a significant reduction in energy expenses. Some homeowners report up to 40% on savings with their energy bills.

Q: Will noise from the return and supply vents be reduced with Aeroseal air duct sealing?

A: This noise typically comes from rushing air through undersized ductwork or if there is a limited amount of air flowing through the indoor coil of your HVAC system. Your local HVAC professionals can help you determine the best way to reduce noise levels.

Q: Can I expect less dust built-up in my home with Aeroseal air duct sealing?

A: When there are leaky return ducts, they will pull all sorts of dust and other indoor contaminants that will inevitably return back to the HVAC unit and they will be redistributed in your home. Aeroseal air duct sealing will reduce leakage up to 90%, ultimately reducing dust and other contaminants in your home significantly.

Q: Can I get my money back if Aeroseal air duct sealing doesn’t work? Is it guaranteed?

A: There is a 10-year warranty provided by Aeroseal when their process is used. Aeroseal air duct sealing has been endorsed by The Environmental Protection Agency and we have full confidence in this product. Of course, the warranty is for on-site seal failures and does not cover additional damage from accidents, general wear and tear, damage from rodents, or subsequent replacement of failed ducts. Even so, the number of warranty claims has been minimal.

Lisa franci

I just had my furnace, hot water heater and A/C replaced. I was nervous to make a decision on which company to trust for such large purchases and work. From start to finish, I felt the most comfortable with Mike the salesperson and then the team who did the work today. They were all efficient, gave clear explanations about the work they did and extremely courteous. I’m relieved that the experience was such a positive one. I feel I received high quality work with very skilled technicians at a very fair price. Thank you so much and I will be happy to ever be a reference for you.

Elizabeth MacDonald

Snow was blocking an exhaust vent outside on Sunday night/early Monday. My furnace shut off. I called this HVAC company, who did work here about 5 years ago. A super professional man came through bad streets and tons of snow and fixed the issue within hours of my call. Great customer service. I highly recommend this company!

Andrew Z.

Used them for AC install, great pricing and quality. Also contacted them for furnace issues with producing enough heat and cycling too often. Instead of a service call they suggested I inspect my HVAC filter, they informed me that some furnaces have issues with high efficiency filters (MERV 13). After I put the old filter back in all functioning as designed. Highly recommend Gustafson HVAC.

Paula Lindse

First rate quality service, fair and reasonable pricing, very professional. We had received 3 other bids and Gustafson was by far the most reasonable and responsive team. Mike supervised the team the whole time. Group of install guys were fantastic. Cleaned up everything, walked me thru operations of new furnace and air conditioner. Arrived on time, installed both furnace and air conditioning unit in about 6hrs. A+ recommendation and will have our business in the years to come.

Mike Grippe

Highly recommend Gustafson. Mike came out and provided a detailed estimate and scope of work. Their crew showed up on time and they were very careful to not to make a mess. Tarps were put down to ensure everything was kept clean. Install went great, and I couldn’t be more pleased with the workmanship. You can’t go wrong doing business with Gustafson!

Jody McGuirk

I cannot recommend this HVAC company enough. They responded promptly to my initial request. Answered all my questions throughout the process. Had the most reasonably priced options out of three companies we called for estimates, as well as provided more service for that reasonable price. They were on time for installation, did a great job of installing and keeping the area clean. We had new furnace and AC system installed. On top of it-the new system works great and is quite. We are very happy!

Sean Tynes

They were scheduled to come out in 5 days to fix the AC in our new house we had just moved into. My mother in law that lives with us is going through chemo and the heat was making it even more difficult for her. They came out the next morning and fixed our issue. The technician was really nice and sincere. I would recommend them to anyone

Pierre Gutierrez

Robert Gomez performs the highest quality job that I have ever received for HVAC. I’m extremely pleased with the service and will be using Gustafson going forward. Robert is extremely knowledgeable and is detail oriented. Absolutely 5 star as he goes above and beyond. Highly recommended for quality service. Thanks!

Krista Bunten

I had the whole HVAC system installed by Gustafson about three years ago and recently requested maintenance on the system. Technician Robert Gomez was the tech that responded and he was very personable, easy to talk to, and explained what he was doing to me to service my furnace. I felt like I received thorough service and he provided advice for the future as well. Thank you, Robert!! I hope to be able to request you again in the future to do maintenance on my AC next spring.

Nancy S

We had a new a/c and furnace installed this spring by Gustafson. They were able to come and give us an estimate within a couple days. We got scheduled for the install within a week. They were on time the day of the appointment and made sure everything was done perfectly and there was no mess. When they were here to do the install, we decided to have the hot water heater replaced. They noticed that the main shut off for the water was leaking in the crawlspace, so had them do that too. They got that done the following day. The price was a lot less than the other estimates obtained. They are an approved vendor with Excel and they completed all the paperwork for the rebate. Happy we went with them and no regrets. Highly recommend them.
