What ACCA QA Certification Means for NH Homeowners
A.J. LeBlanc Heating is an ACCA Quality Assured (QA) certified heating and air conditioning contractor. The certification is awarded by the Air Conditioning Contractors of America (ACCA), the national trade organization representing residential and commercial HVAC contractors. ACCA QA certification reflects sustained adherence to industry-standard installation quality, customer service practices, and ethical business standards. For NH homeowners evaluating contractors, ACCA QA certification is a meaningful credential.
What ACCA QA certification represents
The Air Conditioning Contractors of America Quality Assured program is a rigorous certification process that evaluates HVAC contractors against documented industry standards. To become and remain ACCA QA certified, a contractor must:
- Demonstrate technical proficiency in installation, commissioning, and service procedures
- Maintain consistent customer service practices and documented service standards
- Follow ethical business practices including transparent pricing and honest sales
- Undergo on-site inspections of completed installations
- Maintain ongoing technician training and certifications
The certification is not a one-time achievement. Continuing compliance is verified through audits and renewal requirements.
What ACCA QA certification means for customers
Installation quality you can verify
ACCA QA covers the actual installation work, not just sales practices. Heat exchanger inspection, refrigerant charge verification, ductwork sealing, combustion analysis, and proper commissioning are all covered by the standards. Customers benefit from work that has been measured against an external benchmark, not just internal company standards.
Transparent pricing
ACCA QA contractors are expected to provide detailed written estimates that clearly identify equipment, labor, parts, and any optional add-ons. No surprise fees at completion. No misleading "diagnostic charges" hidden in the price.
Technical expertise across the team
The certification standard covers the technicians performing the work, not just the company leadership. Our installers and service technicians receive ongoing training that keeps them current with industry developments: new refrigerants (R-32, R-454B), evolving efficiency standards (SEER2, HSPF2), inverter heat pump commissioning, smart thermostat configuration, and current code requirements.
Ethical sales practices
The certification requires that contractors recommend equipment and services that genuinely fit the customer's needs. ACCA QA contractors do not upsell systems beyond what a customer actually requires, and do not push equipment that the home cannot use effectively.
What this looks like on a job
For an A.J. LeBlanc Heating installation, the standards translate into specific practices:
- Manual J load calculation performed on every replacement and new installation
- Written estimate with itemized equipment, labor, and parts
- Permits pulled and inspections coordinated for every project that requires them
- Triple evacuation on refrigerant systems before charging
- Combustion analysis with measured CO and CO2 readings on every fuel-burning installation
- Commissioning checklist completed and documented
- Owner orientation on the new system before we leave the job
- Documented warranty terms in writing
How ACCA QA complements other credentials
ACCA QA is one of several credentials our team holds. Together they form the full picture:
- ACCA QA - installation quality and customer service standards (this certification)
- EPA Section 608 - federal refrigerant handling certification (required by law)
- NH gas fitter, plumbing, and electrical licenses - state licensing for the trades
- Mitsubishi Diamond Dealer - manufacturer certification (Mitsubishi)
- Bosch Platinum Dealer - manufacturer certification (Bosch)
- PHCC membership - state trade association membership
The full list of credentials and manufacturer certifications is available on our memberships page and manufacturers page.
Why this matters for your installation
A heating, cooling, or plumbing installation is an investment that lives in your home for 10 to 25 years. Equipment is part of the picture, but installation quality determines whether that equipment actually delivers its rated performance, hits its expected lifespan, and stays under warranty coverage.
Credentials like ACCA QA give you a way to verify that the contractor you choose meets external standards for quality work, beyond marketing claims. They are not the only thing that matters, but they are a useful filter.

Frequently Asked Questions
What is ACCA QA certification?
The Air Conditioning Contractors of America Quality Assured program. A national HVAC contractor certification that evaluates how a contractor installs equipment, serves customers, and conducts business, measured against documented industry standards.
How is ACCA QA different from manufacturer certifications?
Manufacturer certifications (Mitsubishi Diamond, Bosch Platinum, etc.) are brand-specific and focus on equipment knowledge for that manufacturer's product line. ACCA QA is brand-neutral and focuses on workmanship and customer care across the trade.
Is ACCA QA required for HVAC contractors?
No. ACCA QA is voluntary. Many contractors operate without it. The certification is a way for contractors to demonstrate commitment to industry-standard quality, and for customers to verify that.
Does ACCA QA affect my warranty?
The ACCA QA certification itself does not change manufacturer warranty terms, but the practices it requires (proper Manual J sizing, correct commissioning, written documentation) help ensure warranty coverage is preserved.
How do I verify a contractor's ACCA QA status?
The ACCA website maintains a public directory of QA-certified contractors. You can also ask the contractor for their certification number and verify directly.
