About All Seasons Heating and Cooling
Family Run Heating & Cooling Business, Rooted in the Great Lakes Bay Region
All Seasons Heating and Cooling has been serving Midland families for more than 40 years. Jeff Kohtz began the business in 1979 by providing heating and cooling repairs and installations throughout the Great Lakes Bay Region, working directly with homeowners who needed honest help keeping their homes comfortable.
What started in Jeff and Gerri Kohtz’s home grew into a family owned and operated company that still carries their values forward today. Their sons, brothers Paul and Mark Kohtz, now run the company, and we still measure every decision against a simple standard: protect our customers’ health and safety, show up when we say we will, leave the job site clean, and communicate clearly from the first call to the final walk-through.
We care about this community the same way we care about our customers’ homes. Our success and the well-being of our neighbors are tied together, and we take that seriously every time we step into a home.
If you’d like to talk through a comfort or safety concern in your home, give us a call at (989) 710-9390. We’re happy to answer questions and help you figure out what makes sense for your family.
What Accountability & Safety Mean in Your Home
Accountability is more than a selling point or a tagline. It means being committed to transparency correcting mistakes when they happen. And that's exactly what we do. When something isn’t right, we take responsibility and learn from it so the next job is better than the last.
Our customers and our team matter to us. We’re dedicated to protecting not only the health and mechanical safety of the community but also the cleanliness of our workspaces, making sure they’re free of debris and hazards when we leave. That focus on safety guides how we install, repair, and maintain equipment so your home can stay as safe and comfortable as possible through every season.
We work to offer a high-quality experience in home service from start to finish: the first call, the service options we present, the sales consultation, and the workmanship of the installation. Our goal is that you feel informed at every step and not left guessing about what’s happening in your home.
Continuous Training & Clear Standards You Can Count On
We’re home services professionals committed to being lifelong learners. We keep growing through weekly team training sessions, educational workshops, and individualized classes specific to our roles. That way, the work we do today reflects what the industry demands right now, not what was common ten years ago.
We keep investigating and investing in new technology, and we also refine our processes and procedures to make our work more precise. Whether we’re tuning a furnace, improving indoor air quality, or working on a water heater, you benefit from a team that trains every week to stay current with new equipment and repair techniques.
Here are a few concrete ways we back up those standards:
- Licensed & Insured: We’re fully licensed and insured (license numbers 7102453 and 7113342) for your comfort, safety, and peace of mind.
- Transparent Pricing: We provide upfront, honest pricing with no hidden fees, so you know what to expect before any work begins.
- Satisfaction Guarantee: If something isn’t right, we fix it, learn from it, and move forward, because standing behind our work is part of who we are.
- Clean, Respectful Service: We respect your space, which is why we leave our work areas free of debris and hazards when the job is done.
- Parts-Stocked Trucks: Our trucks carry universal parts, common igniters, flame sensors, gas valves, and blower components, which means fewer return trips and faster repairs.
- Honest Maintenance Plans: Our Service Club Plan and Club Plus Plan focus on routine tune-ups for your furnace and air conditioner, helping catch small issues before they turn into bigger problems.
Neighbors You Can Call When Comfort Matters
At All Seasons Heating and Cooling, we are your neighbors, not a faceless contractor. We live and work in the Great Lakes Bay Region, and we know how much it matters to have a home that feels safe and comfortable in every season. When you invite us in, you get a team that treats your home with the same care we want for our own families.
From that first phone call through the final walk-through, our mission is to protect your comfort and safety, communicate clearly, and leave your home in better shape than we found it. Whether you’re dealing with a heating or cooling problem, concerned about indoor air quality, or planning ahead with maintenance, we’re here to help you make informed decisions.
When you’re ready to talk about your home’s comfort, call (989) 710-9390 and connect with our team at All Seasons Heating and Cooling.
