18 Yrs On The Tools
B&B Mechanical was built the way most good trade businesses are: one job at a time, one referral at a time. Owner Jonathon Hanna started on the tools eighteen years ago and has never left them. Today the company serves homes, businesses and industrial sites across Brazoria, Matagorda and Montgomery counties from its base in Bay City.
Roughly 70% of our work is commercial: rooftop units, packaged systems, preventative maintenance programs and the repairs that keep restaurants, offices, clinics and warehouses running. The other 30% is residential, and it gets the same technicians, the same parts and the same standards.

Four commitments that shape every call we run, from a thermostat swap in Lake Jackson to a full commercial retrofit in Bay City. They are the reason most of our work comes from referrals and repeat customers.
We look at the whole system, explain what we found in plain language and recommend only what the equipment actually needs.
Clear pricing approved by you before any work starts. No call-out surprises and no upselling, on a home or a commercial site.
Quality parts, proven methods and a job done right the first time, whether it is a thermostat swap or a rooftop unit.
Licensed TACLA125339C and regulated by the Texas Department of Licensing and Regulation. Every system is tested before we leave.
Rated 5.0 on Google, Yelp and Nextdoor. Here’s what our neighbours say.
We called B&B early on a Monday morning — our AC went out in the middle of the night, July of all times! They responded and repaired everything in less than two hours, cold AC cooling the house down again! THANK YOU, highly recommend B&B Mechanical — professional and dependable!
