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.
Heating Services in Coleman, MI
Michigan winters in Midland County mean sub-freezing overnight temperatures and steady snowfall from November through March. A furnace or heat pump that's overdue for service isn't a minor inconvenience. It's a real risk to your family's comfort and safety. Our heating services cover installation, repair, and routine maintenance across the full range of residential systems.
Furnace Installation & Repair
When a furnace fails mid-winter, response time matters. Our trucks carry universal parts, common igniters, flame sensors, gas valves, and blower components on every run, which means many repairs can be resolved in a single visit instead of ordering parts and coming back days later. Whether you need a furnace installation or a repair on an existing unit, we can walk you through the options and explain what we're doing before we touch anything.
Choosing the right furnace for your home takes more than picking the highest-efficiency model. We assess your home's size, layout, and existing ductwork to recommend a system that performs as designed and fits your budget.
Heat Pump Systems
A heat pump handles both heating and cooling from a single system, which makes it a practical all-season investment for Coleman homeowners who want to simplify their equipment. Modern heat pumps can perform reliably through Michigan winters when they're properly sized and installed.
If you're weighing a heat pump against a traditional furnace-and-AC setup, we can walk you through the tradeoffs based on your home's specific load requirements. No upsell, just the information you need to decide.
Cooling Services in Coleman, MI
Central Michigan summers push daytime highs into the upper 70s and low 80s regularly, with heatwaves climbing higher. A functioning air conditioner isn't a luxury during those stretches, and a system that fails in July can mean a long wait if you haven't planned ahead. Our cooling services include full AC installation and replacement, repair, and preventive maintenance: the kind of tune-up that catches refrigerant issues, capacitor wear, and airflow restrictions before they turn into a mid-July breakdown.
Every cooling job comes with upfront, transparent pricing. You'll know exactly what the work costs before we start. We back all repairs, maintenance, and installations with a 100% satisfaction guarantee. If something isn't right when we're done, we come back and fix it. That's not a marketing promise. It's how we've kept customers in this area since the Carter administration.
Smart Thermostats in Coleman, MI
A smart thermostat is one of the more straightforward upgrades available to Coleman homeowners. It's compatible with most modern furnace and air conditioning systems and able to learn your household schedule to reduce energy use without constant manual adjustment. Remote temperature control from a smartphone is useful when you're away from home or heading back early. We install and support smart thermostats as part of our broader HVAC service offering.
More importantly, we make sure the thermostat is configured correctly for your existing system before we leave. A mismatched or improperly wired thermostat can cause short-cycling and wear out your equipment faster. We handle the installation as part of a complete system relationship, not a one-time product drop-off.
Perfect Your Indoor Air Quality in Coleman, MI
The ductwork that supports your home's HVAC system carries more than warm or cool air. Dust, pollen, pet dander, and mold spores circulate through ductwork and back into living spaces, affecting anyone with allergies, asthma, or other respiratory sensitivities. Michigan's dry winter air compounds the problem, straining respiratory comfort and damaging wood floors and furniture over time. Indoor air quality solutions work with your existing HVAC equipment to address these issues at the source.
Humidifiers
We install and service humidifiers for whole-home moisture control during heating season. The right system helps relieve dry-air discomfort and supports a more comfortable home environment during winter.
Air Scrubbers
We also install and service air scrubbers for active air purification. These systems help address airborne contaminants inside the home.
The right solution depends on what's actually happening in your home. Our team can assess the specific issues you're dealing with and recommend what fits your system and your household, rather than defaulting to a one-size-fits-all answer.
Durable Water Heaters
Tank water heaters typically last 8 to 12 years. Tankless models last longer, often 15 to 20 years with proper maintenance, and deliver hot water on demand without keeping a full tank heated around the clock. Whether your unit is aging out or has already failed, we handle installation, maintenance, and repair for both tank and tankless water heaters. Like every service we provide, water heater work comes with upfront pricing. You know the cost before we begin.
Our satisfaction guarantee covers water heater installations the same way it covers HVAC work. If you're comparing us to a box-store installer, the difference is accountability: we're local, we're licensed, and we stand behind the job after we leave. Our technicians can help you choose the right unit for your household's hot water demand and your home's setup, not just whatever's in stock.
