Thomson AC / Huntington Beach
Asbestos Duct Removal & Replacement in Huntington Beach
A lot of older homes in Huntington Beach, Rossmoor, Seal Beach and Los Alamitos still have their original asbestos duct wrap. Here’s how we handle it: a licensed, professional abatement company safely removes the old ducts, and then we install a new, properly sized duct system.
We don’t do the abatement ourselves. We coordinate it, then do the duct work.
▶ Watch video: Asbestos air duct removal, step by stepSigns you have asbestos duct wrap
- Paper or tape wrap.
White, grey or off-white paper-like wrap around round metal ducts, often taped at the seams. - Corrugated grey sleeves.
A thick, cardboard-textured sleeve over the duct that crushes easily. - Hard cement-like ducts.
Dense grey duct board or pipe, often under the slab or floor. - The age of the house.
Homes built or re-ducted before the mid-1980s are the ones to check.
You can’t confirm asbestos by eye. Only a lab test can. Until then, don’t sweep, vacuum, cut or drill near it.
How to tell if your ductwork has asbestos

We balance airflow to each room, insulate exposed sheet metal and connections, and adjust refrigerant charge if needed.

Asbestos duct questions, clearly answered
How much does asbestos duct removal and replacement cost?
On a typical home, abatement by a licensed, professional abatement company runs about $1,200. Our attic duct replacement package is $4,130 for up to 8 supply runs, or $5,740 for up to 15. Your exact price comes from a free on-site estimate.
Does Thomson remove the asbestos?
No. A licensed, professional abatement company removes the asbestos. You sign with them and pay them directly, and we coordinate the schedule. Once the abatement is done, we install your new duct system.
How do I know if my ducts have asbestos?
You can’t tell by looking. Grey or white paper wrap, corrugated grey sleeves and hard cement-like ducts are warning signs in homes built before the mid-1980s, but only a lab test confirms it. Until then, leave it alone.
Is it safe to run my system with asbestos duct wrap?
Intact wrap that stays undisturbed generally doesn’t release fibers. If the wrap is crumbling near a return or the air handler, shut the system off and call us.
What’s included in the duct replacement?
We remove and haul away the old non-asbestos ductwork, then install Class-1, R-8 insulated, Mylar-faced flexible duct sized for your equipment, with adjustable damper disks to balance airflow. We insulate exposed sheet metal and connections and check refrigerant charge if needed. The flexible duct carries a 10-year manufacturer warranty from Quietflex.
Can I finance the project?
Goodleap financing is available for our duct work. The abatement is paid directly to the abatement company, so it can’t be part of our financing.

It was time to service the fan blower unit and had a pleasant experience again working with Glenn and his trainee George. I appreciated the time Glenn took to ensure George's work met the expectations that Glenn would have performed the job to. It's not often companies have seasoned experienced employees that can share their knowledge and experience with new staff. I hope Thomson keeps Glenn around for many more years!

Over the years, we've used Thomson to do major HVAC construction, equipment replacement and service. They are always very thorough, knowledgeable, considerate and the prices are fair. They have a lot of experienced technicians on their team and communicating with the office is easy. We get our system serviced every 6 months (very important) and they actually offer a monthly payment plan for that. I didn't take off a star (because they do offer a fantastic service), but it is difficult if something breaks during the weekend. They won't respond until offices open on Monday. But they will get you in as soon as possible and the service is great.

Very honest company and great customer service. It’s been a long time since we had our AC unit inspected and after all these years it’s still good to go and ready for summer! Ethan did a great job answering all my questions. Quick, efficient and very knowledgeable. Thanks Thomson!

Ethan was great and was very helpful in helping me understand the unit. He came out the same day I called and had parts on his truck to make the repairs right then and there. Ethan was very friendly and I would recommend him and Thomson Air Conditioning to anyone in the future.
