About Garner Heating And Cooling LLC in Tecumseh, MI
Family-Owned HVAC Service With Three Decades of Experience
Garner Heating And Cooling LLC is a family-owned and operated HVAC company based in Tecumseh, bringing more than 30 years of experience to homeowners throughout Lenawee and Washtenaw counties. We're fully licensed and insured, and every installation, repair, and maintenance call is handled by our family team—not rotating technicians you've never met.

When you call us, you work with people who know your system, remember your home, and take personal responsibility for every job. That continuity matters when you're dealing with a furnace failure in January or an air conditioner breakdown in July. You get the same skilled professionals every time, and you benefit from the accountability that comes with a family name on the truck.
Our 30-plus years in the trade mean we've worked on every major brand, diagnosed problems other companies missed, and installed systems that are still running efficiently years later. We understand how ductwork affects airflow, how insulation impacts efficiency, and how to size equipment correctly so you're not paying for capacity you don't need or struggling with a unit that can't keep up.
We serve Tecumseh, Ann Arbor, Saline, Dexter, Dundee, Clinton, Blissfield, Brooklyn, Milan, Ypsilanti, Chelsea, Manchester, and surrounding areas. Whether you need a new installation, a repair, or seasonal maintenance, you're working with a local team that's been doing this work for three decades.

Local Presence and Deep Trade Knowledge
Operating from our Tecumseh base, we've built our business on repeat customers and referrals from neighbors who trust our work. You won't find us sending out different crews each visit or hiring inexperienced helpers to cut costs. Our family handles the work, and that means consistent quality, thorough diagnostics, and repairs done right the first time.

Southeast Michigan's climate demands reliable heating and cooling—winter temperatures regularly drop below freezing, and summer humidity can make even a well-sized air conditioner work harder than expected. We account for those conditions when recommending equipment and setting up maintenance schedules, because we've seen what happens when systems aren't maintained properly or when installations cut corners.
Our 30 years of experience cover residential installations, commercial systems, emergency repairs, and everything in between. We've replaced outdated furnaces in century-old homes, installed high-efficiency heat pumps in new construction, and diagnosed intermittent problems that only show up under specific conditions. That depth of experience means faster diagnostics, better recommendations, and solutions that actually solve the problem instead of masking it.
We're committed to serving local customers with the same attention to detail and trade knowledge that's kept us in business for three decades. When you hire a family-operated company, you're hiring people who stake their reputation on every job—and that changes how the work gets done.
Attention to Detail and Consistent Service
You work directly with our family team from the initial call through project completion. We explain what we find, walk you through your options, and answer questions without rushing you toward the most expensive solution. Our focus is on matching the right equipment and approach to your home, your budget, and your comfort needs.
