Heating and cooling sales, installation, and repair for Nashville homes and businesses — backed by 25+ years of family-run, neighbor-to-neighbor service.
"Good, honest work. Would recommend 1000x!"
— Sarah Olivier
Whether it's a routine maintenance check or an emergency repair on a unit that's stopped working, our technicians cover every heating, cooling, and ventilation need in Nashville and the surrounding area.
Right-sized HVAC sales and installation for new construction, additions, or full replacements — picked for your home, not a one-size catalog.
Upgrading from an aging system? We'll walk you through efficient, dependable options that fit your budget and your home.
A diagnostic-first approach to AC repair — we figure out exactly what's wrong before we quote, so you only pay for what you need.
From frozen heat pumps after a Nashville ice storm to a furnace that won't kick on, we get heat back on fast and explain what we did.
Spring and fall tune-ups that catch small problems before they become breakdowns — and keep your system running at peak efficiency.
Heat out at midnight? AC failed in July? Our 24-hour emergency line is the same number on this page — you'll talk to a real person.
Our mission is simple — provide honest, reliable service to every customer, every time. For more than 25 years we've been the heating and cooling company Nashville families and business owners call when they need work done well, explained clearly, and priced fairly.
We're licensed, bonded, and insured. We answer the phone. And we treat every job — from a quick filter change to a full system replacement — like it's going in our own home.
"What a great a company. Very professional. Great communication. We have heat! Thanks to Jason, Evan and Major. Very friendly — was like I'd known them all my life. You just don't see that kind of customer service hardly anymore. Will definitely be my go-to heat and air company from now on."
"I recently learned about J & J Mechanical. Soon after the January 2026 ice storm in Nashville, Jason came by the same evening I called — even though he was covered up with work that day. He kept me from freezing with his prompt arrival, repair, advice and expertise. His workers are licensed, insured and bonded, and know what they are doing. Their prices are competitive and reasonable and I highly recommend them."
"J&J was incredibly easy to work with. Jason was in and out of my home in under an hour and had diagnosed and fixed the issue with my furnace. Good, honest work. Would recommend 1000x!"
From South Nashville out through Brentwood, Antioch, Donelson, and the surrounding communities — we cover both commercial accounts and residential service calls across Davidson County and beyond.
Heat out in the middle of the night? AC quit on a 95° afternoon? Call the emergency line. You'll talk to a real person from the family — not a call center.
