About Hannon Heating & Air Conditioning
A family business built on honest work and lasting relationships.
Our Story
With over 30 years in the HVAC trade, Paul Hannon founded Hannon Heating & Air Conditioning in 2014 with a straightforward belief: every customer deserves HVAC service they can trust. That belief drives everything we do.
As an owner-operated company based in Bellingham, MA, we take a different approach than the big outfits. Paul is personally involved in the business every day. When you call Hannon HVAC, you're not navigating a phone tree — you're talking to people who know your system and care about getting it right.
We've built our reputation one job at a time across MetroWest Massachusetts. Our customers come back year after year, and they refer their friends and family. That's the kind of trust you earn by showing up on time, doing quality work, and charging a fair price.
The Hannon Difference
Here's what sets us apart from other HVAC companies in the area.
Upfront Pricing
We provide a written quote before starting any work. If the scope changes, we'll discuss it with you first. No surprises on your bill — ever.
Fully Stocked Vans
Our service vehicles carry the parts and tools needed for most common repairs. That means fewer follow-up visits and faster resolution of your HVAC issues.
Owner-Operated
When Paul's name is on the company, quality is personal. You'll always have direct access to the business owner, not a call center.
All Brands Serviced
We work on every make and model of heating and cooling equipment. No matter who installed your system, we can service it.
Factory Trained
Our technicians are factory trained and certified on the latest HVAC technology. Continuing education keeps us current with industry advances.
Community Focused
We live and work in the communities we serve. Our neighbors are our customers, and we treat every job like it's our own home.
Certifications & Credentials
Our certifications aren't just badges — they're proof that we meet the highest standards in the HVAC industry.
EPA Certified
EPA Section 608 certification is required for any technician who handles refrigerants. This means we follow all federal regulations for properly handling, recovering, and disposing of refrigerants — protecting both your home and the environment.
ACCA Member
The Air Conditioning Contractors of America (ACCA) is the leading trade association for HVAC contractors. Membership means we follow industry best practices for system design, installation, and service — including Manual J load calculations for proper equipment sizing.
Our Promise to You
When you choose Hannon Heating & Air Conditioning, you're choosing a company that puts your comfort and peace of mind first. We promise to always be straightforward about what your system needs, transparent about costs, and committed to doing the job right the first time. If we wouldn't recommend it for our own home, we won't recommend it for yours.
