All Seasons Heating and Cooling Service Club Plan

Year-Round Peace of Mind for Great Lakes Bay Region Homeowners

Michigan winters don’t ease in gently, and Midland summers push cooling systems just as hard. Regular care for your heating and cooling equipment isn’t a luxury. It’s how you avoid the breakdown that hits at 10 p.m. in February. Our Service Club Plan starts at $11.95 per month and bundles routine maintenance, priority scheduling, and repair discounts into one straightforward program, so you’re never caught off guard.

All Seasons Heating and Cooling is a family-owned business that’s been part of the Great Lakes Bay Region since 1979. Brothers Mark and Paul Kohtz now carry on what their parents Jeff and Gerri Kohtz built from the ground up: more than 45 years of heating and cooling service for local families.

Ready to lock in priority service and stop guessing about your HVAC system? Call us at (989) 710-9390 or keep reading to see exactly what’s included.

What Our Service Club Plan Includes

Our HVAC maintenance plan goes beyond quick checkups. It’s a full-service program that gives you real, measurable benefits while helping your equipment run better and last longer. Every item below applies to active club members: no fine print, no surprise fees.

  • Appointments Within 24 Hours: When something goes wrong, you don’t want to wait. Club members get priority service with scheduling within 24 hours, including holidays and weekends.
  • Discounted Diagnostic Fee: Club members pay just $41, half the standard rate, on every service call, including holiday and weekend visits.
  • 10% Off All Repairs: A 10% discount is automatically applied to any repair work needed after an inspection.
  • Full 21-Point Tune-Up: Every inspection follows a detailed 21-point checklist. We verify the smart thermostat, test electrical components, inspect the heat exchanger, clean the unit, check refrigerant levels, test the capacitor, clean the condenser coil, and confirm proper drainage, among other checks.
  • Clean, Respectful Service: We call before arriving, wear shoe covers, use protective mats, and clean up completely before we leave.

The base Service Club Plan covers one system: your furnace or your air conditioner. If you want both covered, the Club Plus Plan includes routine tune-ups for your furnace and air conditioner under a single membership. For most Midland homeowners who run their heat all winter and their AC all summer, the Club Plus Plan is the practical choice.

Why Annual HVAC Maintenance Matters for Midland Homes

Skipping annual maintenance rarely saves money. It usually turns a predictable tune-up cost into an unpredictable repair bill, often during the coldest or hottest week of the year. Here’s what routine care through the Service Club Plan actually does for your home.

  • Protects Your Manufacturer Warranty: Many HVAC manufacturers require documented annual maintenance to keep warranty coverage active. A lapsed tune-up schedule can void that coverage when you need it most. Our visits are documented, and we provide a full report at the end of every appointment.
  • Catches Small Problems Early: A worn capacitor, low refrigerant, or dirty coil found during a scheduled tune-up is a minor repair. The same issue discovered during a system failure in July or January can mean an emergency call with emergency pricing and a home that isn’t comfortable in the meantime.
  • Lower Monthly Energy Bills: A clean, properly calibrated system can run more efficiently. That efficiency can show up on your utility bill every month, not just when a technician is on-site.
  • Better Indoor Air Quality: Every tune-up includes a review of your air filters and duct conditions. Restricted airflow and dirty filters don’t just strain the system. They affect what your family breathes every day.
  • Safety Checks Every Visit: The 21-point inspection includes a heat exchanger check for cracks that can allow carbon monoxide into your home and an electrical component review that can reduce fire risk. These aren’t optional add-ons. They’re part of every Service Club visit.
  • Longer System Lifespan: Systems that receive regular care can accumulate less wear on critical components. That can mean more years of reliable operation before a full replacement becomes necessary.

We back every Service Club visit with our satisfaction guarantee and our clean-house promise. If you’re ready to stop reacting to HVAC problems and start staying ahead of them, call us at (989) 710-9390 or schedule your Service Club Plan online today.

    The Way HVAC  Service Should Feel

    Honest pricing, clean work, and a team that stands behind every job. This is what we show up to deliver every time.

    • Fully Licensed & Insured

      Every technician is fully certified and insured, so you can trust the work and the people doing it.

    • 100% Satisfaction Guarantee

      We don't consider the job done until you're completely happy with the results. That's our promise.

    • Clean House Guarantee

      We wear shoe covers, use protective mats, and clean up before we leave. Your home stays yours.

    • Upfront Pricing

      No surprise bills. You'll always know the cost before any work begins - straightforward and honest.

    • Maintenance Plans

      Our Warrior Program and All Seasons Club Plan includes priority scheduling, a full 21-point tune-up, discounts on repairs, and more. 

    • Family-Owned Since 1979

      Two generations of the Kohtz family have been keeping Midland homes comfortable. That kind of history means experience you can actually count on.

    Comprehensive Tune-Ups by Trained Technicians

    Our tune-ups aren’t rushed or surface-level. Each visit follows the full 21-point checklist: drainage check, capacitor test, condenser coil cleaning, thermostat verification, refrigerant check, heat exchanger inspection, and more. We look for signs of wear on critical components and test the parts most likely to fail under heavy seasonal load. This kind of attention can help maintain efficiency and keep your system steady when it’s working hardest.

    Our technicians train every week to stay current on new equipment models and repair techniques, so what they bring to your home reflects what the industry demands right now. After every visit, they walk you through what they found, explain any recommendations, and leave you with a full written report, so you know the condition of your system, not just that someone stopped by and looked at it.

    Add Your Tanked Water Heater to the Plan for Complete Coverage

    If your home uses a tanked water heater, you can easily include it in your Service Club Plan for a small additional investment. Your water heater plays a big role in everyday life, and just like your furnace or air conditioner, it benefits from routine care. This add-on service is performed at the same time as your furnace tune-up, so there’s no need to schedule an extra appointment.

    The Warrior Program: A Special Thank-You for Military Families

    We’re proud to support the men and women who have served in the military. That’s why we created the Warrior Program: a complimentary lifetime Service Club Partner Plan for veterans and active military members. Enrollment is free, and there are no service fees.

    To join, simply stop by our office with a military ID. The plan is available for homeowners living in their primary residence and currently covers central air units, furnaces, and water heaters. If anything happens to the primary account holder, the plan can be transferred to a spouse.

    Why Midland Homeowners Choose All Seasons Heating and Cooling

    Every HVAC company will tell you they do quality work. Here’s what sets our Service Club Plan apart.

    • Family-Owned & Operated Since 1979: More than 45 years of continuous service in the Great Lakes Bay Region. Mark and Paul Kohtz run the company their parents built. This isn’t a franchise or an out-of-state operation.
    • Licensed & Insured: We hold Michigan HVAC licenses 7102453 and 7113342. Every job is backed by credentials you can verify.
    • Parts-Stocked Trucks: Our trucks carry universal parts, common igniters, flame sensors, gas valves, and blower components. If a tune-up turns up a repair, we can often handle it the same visit: no second trip, no waiting another week.
    • Upfront Pricing, Always: You’ll know the cost before we start any work. No hidden fees, no surprises on the invoice.
    • Satisfaction Guarantee: If something isn’t right, we fix it, no excuses.
    • Senior & Military Discounts: We offer a senior discount for qualifying homeowners and the Warrior Program for veterans and active-duty military: a lifetime complimentary membership with no monthly fee.

    If something goes wrong on a job, we own it, fix it, and learn from it. That accountability is built into how our team operates, not just stated in a mission statement.
