Seal Hidden Leaks. Save Energy. Breathe Easier.
Leaky ductwork is one of the most common—and costly—issues in HVAC systems. When conditioned air escapes through gaps, it leaves your home’s temperatures uneven, makes your equipment work harder, and can draw in dust or contaminants from attics, crawlspaces, or garages. We see an average of 25–40% of conditioned air being lost through holes and gaps in ductwork, and this makes a big impact on your comfort and heating and cooling costs. Pacific Heating & Cooling offers HVAC air duct sealing with Aeroseal, the industry-leading technology that seals leaks from the inside out—without tearing into your walls or ceilings.
Why Duct Sealing Matters
- Lower Your Energy Bills
Stop paying to heat and cool air that never reaches your rooms. Aeroseal helps reduce energy waste by sealing leaks and optimizing system performance. - Improve Airflow and Comfort
Eliminate hot and cold spots. Aeroseal balances airflow throughout your home, improving room-to-room comfort and HVAC efficiency. - Breathe Cleaner Air
Sealing return ducts prevents dust, allergens, and pollutants from entering your system and recirculating in your home. - Extend Equipment Life
When your system doesn’t have to work as hard, it lasts longer. Aeroseal reduces strain on your HVAC equipment, which means fewer breakdowns over time.
Do I Need Air Duct Sealing?
Duct cleaning and furnace filter changes will not solve the discomfort from a leaky system, and your best solution is duct sealing, which keeps conditioned air within the system for more efficient and consistent heating and cooling. You may benefit from duct sealing if:
- Some rooms are much hotter or colder than others
- Airflow feels weak at certain vents
- Energy bills are rising without a clear reason
- The HVAC system runs often, but your home still feels uncomfortable
- Dust seems to return quickly after cleaning
- HVAC system disperses odors or dust from an attic, crawlspace, basement, or garage
- Duct sealing and testing can improve HVAC performance and extend the life of your system
Duct Sealing vs. Duct Cleaning
Cleaning removes buildup inside the ducts, while sealing closes leaks that waste heated or cooled air and can pull dust into the system. Here are some common indoor air quality services and what each solves.
When each IAQ service is best:
- Air Duct Sealing Service
Is best for a lasting fix when room temperatures feel uneven, airflow is weak, or your system seems to waste energy without a known cause. - Air Duct Cleaning
Is best for removing visible buildup from dust, pest infestation, pet dander, or post-construction debris to reduce long-term contamination and odors at the source. - Air Filtration
Is best for ongoing reduction of allergens, odors, smoke, or airborne particles to maintain daily air quality. - HVAC Duct Testing
Is best for evaluating system efficiency or dust source to identify if leaks are causing the problems you’re noticing.
How Aeroseal Air Duct Sealing Works
Aeroseal is a powerful solution, but the real difference comes down to how it’s delivered. Aeroseal for HVAC and air conditioning duct sealing closes leaks from the inside, so there’s no need to tear into walls or ceilings to reach hidden gaps. Pacific Heating & Cooling uses a precise, measurable process that follows these basic steps:
- We temporarily block off your registers and pressurize the duct system.
- Our technicians release a safe, water-based sealant into the air ducts.
- The sealant travels through the system, sealing holes up to ⅝” wide by clinging only to the edges of leaks.
- We monitor the entire process in real-time and provide homeowners with a before-and-after certificate showing how much leakage our work eliminated.

-
-
Yes. Sealing helps more air stay in the duct system, which can improve airflow at vents and help move heated and cooled air more consistently.
-
-
Yes, if your system is consistently losing heated or cooled air, sealing can retain this air to reduce wasted energy and increase equipment efficiency.
-
-
Yes. Sealing addresses air loss, and duct cleaning addresses accumulation. Sealing is best when you notice higher energy bills or discomfort, and cleaning is best when buildup from ducts causes dust or airborne concerns.
