What MaxSeal does
MaxSeal is an authorized Aeroseal dealer operating as a California-licensed contractor (license 1128398) that delivers residential duct sealing services across the Bay Area and Sacramento region. The core technical offering is Aeroseal's patented aerosol-based duct sealing process, in which a polymer sealant is injected into pressurized ductwork and settles at leak points to seal the system from the inside, with reported leakage reductions of up to 95%. MaxSeal's role is service delivery — owning the customer relationship, performing on-site assessments, operating the equipment, and providing a 10-year warranty on completed work — rather than product development.
The business operates on a professional-services model with quote-based per-project pricing and no disclosed subscription or recurring-revenue component. Customers are individual homeowners, and acquisition leverages co-marketing arrangements with HVAC contractor Prime Air Conditioning, home-performance firm Elements, and energy-efficiency programs including Bayren, The Switch Is On, and Tech Clean California, alongside active positioning around the 30% federal tax credit for home energy efficiency improvements. MaxSeal has expanded beyond pure duct sealing into complementary HVAC offerings — insulation, air balancing, and indoor air quality testing — and has entered the new-construction builder vertical driven by California Title 24 energy code compliance. Operations appear owner-operated out of a PO Box mailing address, with no disclosed funding, headcount, or financial data.

MaxSeal competitors and assessment
Company assessmentBroad incumbents
- ServiceMaster Restore: Large national home-services and restoration franchise network. While primarily known for disaster restoration, it competes in adjacent home-performance and duct-related services through its broad service portfolio.
- Stanley Steemer: Large established home-services brand offering carpet, tile, and air-duct cleaning nationwide. Overlaps with MaxSeal on duct-related services but from a broader, more diversified home-services portfolio.
- One Hour Heating & Air Conditioning: National residential HVAC services franchise offering heating, cooling, and duct-related services. Overlaps with MaxSeal as a duct-sealing provider, typically as an add-on to HVAC repair/replacement.
- Servpro: Large national franchise in fire/water restoration and cleaning services, including HVAC and duct cleaning. A broad incumbent that overlaps with MaxSeal on residential duct and indoor-environment services.
Direct peers
- DUCTZ: A national duct-cleaning and air-duct restoration franchise serving residential and commercial customers. Competes in the same homeowner-facing duct-services category with a comparable service-bundling model.
- Aeroseal: The patented technology provider whose authorized-dealer program MaxSeal operates under. Aeroseal itself sells duct-sealing services and equipment directly in some markets and is the most directly comparable business in this niche.
- AdvantaClean: A national franchise specializing in indoor air quality, duct cleaning, and air-sealing services for residential and commercial customers. Overlaps with MaxSeal on duct sealing, duct cleaning, and IAQ-focused home services.
Others
- Carrier Global: Major HVAC equipment manufacturer with a large authorized-dealer network. Indirectly comparable: homeowner's duct-sealing decision is often triggered by Carrier or Trane equipment performance and replacement timing.
- Trane Technologies: Global HVAC equipment manufacturer. Not a direct duct-sealing competitor but the maker of the HVAC systems whose performance MaxSeal's service is designed to protect and improve.
Regional players
- Elements (e3-elements.com): Bay Area home energy-audit and performance firm explicitly named as a MaxSeal partner. Operates in the same Northern California geography with adjacent whole-home efficiency and duct-services offerings.
