Duct Insulation and Air Sealing in Vallejo, CA

Make your home HVAC system more efficient with air sealing and duct insulation in Vallejo, CA. Uninsulated ductwork and air leaks can lead to inefficient indoor temperature control or let in unwanted dust and pollutants.
Your ductwork system is the foundation of HVAC performance in your home. Heated and cooled air travels through ducts to reach every room. Too many leaks or cracks in the ductwork could make it harder to keep rooms cool or hot. Keeping air at the right temperature in the ducts reduces wear and tear on your heater or air conditioner.
Small leaks or cracks in walls or roofs let air escape. They also provide places for outdoor air to invade your home.
The qualified technicians at Environmental Heating & Air Solutions can help improve your indoor air. We handle everything from duct installation and rerouting to insulation and repair.
The Importance of Duct Insulation and Air Sealing

A sealed, insulated ductwork system is an efficient HVAC system. Air sealing and duct insulation serve related but sightly different purposes.
Insulation helps reduce the likelihood of heated or cooled air escaping your system. This better efficiency means your air conditioner or central heating doesn’t have to work as hard.
Installing insulation around ducts also reduces noise from vibrations. Insulating ducts may also fight condensation, which helps prevent mold and mildew.
Unconditioned or exposed areas of ductwork may particularly be susceptible to problems. Insulate ducts in attics, unfinished basements and garages to help reduce the loss of heated or cooled air.
Gaps and cracks in your ductwork lets musty attic air into your ducts, which can lead to smelly indoor air. Duct joints and seams often develop slight gaps.
Air sealing involves closing any gaps, air leaks or cracks in ductwork, walls or roof. These gaps might be anywhere in your home. Small leaks sometimes develop around plumbing or electrical cutouts. Attic fans and vents may also have gaps where air can escape your home. Sealing these tiny gaps keeps heated or cooled air where you need it.
Here are some benefits of having your ducts insulated and sealed:
- Improves HVAC energy efficiency
- Helps maintain even temperatures
- Keeps dust and dirt out
- Reduces musty odors
- Quieter HVAC operation
Because your HVAC system works better with insulated, sealed ductwork, you won’t have to replace major components as often. In the long run, insulation and sealing help save you money while keeping you more comfortable.
