Heating & cooling is now Jenner & Sons.
Reliance focuses on plumbing, electrical, and generators. Our longtime HVAC crew now runs under our sister company — same people, same standards, dedicated phone line.
From rough-in
to last bolt.
Heavy equipment, fully stocked vans, and a crew that takes pride in every trench, joint, and connection. We bring the gear — and the workmanship — to do it right the first time.
Built to last.
Done right.
We built Reliance on a simple promise: show up when we say, fix it the right way the first time, and treat your home like it's our mom's. That's it. No bait pricing, no upsells, no excuses.

People talk.
We listen.
"Hot water tank burst at 9 PM. Reliance was at our door in 40 minutes, swapped it for a tankless the next morning. Honestly the easiest service call I've ever had."
"Generator wouldn't fire up two days before a tropical watch. Reliance had a tech out same morning, diagnosed the transfer switch, and had us storm-ready by dinner. These guys are the real deal."
"Built our new place with Reliance handling all the plumbing rough-in. Inspectors raved. Two years in — not a single issue. Worth every penny."
"Called three other companies, no return calls. Reliance answered the phone, sent Tyler out same morning, fixed a slab leak under budget. New customer for life."
