Trusted HVAC Services in Midland, MI
A Family Owned HVAC Company, Providing Honest Work Since 1979
Jeff and Gerri Kohtz started All Seasons Heating and Cooling out of their home in 1979, and we’ve been part of the Great Lakes Bay Region ever since. Their sons, Paul and Mark Kohtz, now run the business day to day. More than 40 years later, our commitment hasn’t changed: show up on time, do the work right, and treat every home with respect.
Heating, Cooling & More for Your Midland Home
We handle everything a home in Midland needs to stay comfortable year-round. Our heating services include gas and electric furnaces, heat pumps, and heating maintenance, so small issues don’t turn into expensive mid-winter breakdowns. On the cooling side, we take care of central air conditioning repairs, replacements, and tune-ups, and our trucks carry universal parts, common igniters, flame sensors, gas valves, and blower components, so many repairs can be resolved on the first visit.
We also install and service smart thermostats, handle water heater repairs and replacements for both traditional and tankless units, and offer indoor air quality solutions including Air Scrubbers and humidifiers. If your home needs it, we service it.
Service Club Plans That Work in Real Life
Our maintenance plans exist because we’d rather help you catch a heating problem in October than diagnose a breakdown in February. The Service Club Plan covers routine tune-ups for your furnace or air conditioner, with appointments scheduled within 24 hours, discounts on all repairs, and a $41 diagnostic fee that applies even on weekends and holidays. If you want both systems covered, our Club Plus Plan handles furnace and air conditioner maintenance together. It’s a straightforward way to protect the equipment your family depends on without surprise costs.
