Install and Service HVAC Systems Right
Michigan-licensed mechanical contractor serving Bath and beyond
Lutz Mechanical has worked in the HVAC industry since 1999, providing heating, cooling, and ventilation services to residential and commercial properties within roughly 45 miles of Bath. The company handles furnace and air conditioner installations, boiler systems, mini-split units, ductwork fabrication, radiant heat, water heaters, gas piping, and commercial rooftop units. Whether you need a new system designed and installed or repairs on existing equipment, you're working with a family-owned contractor who knows the demands of Michigan's climate.
You might be replacing an aging furnace before winter arrives, adding zoned cooling with mini-splits, or upgrading ductwork that's restricting airflow. Each project calls for accurate sizing, clean installation, and equipment matched to your building's layout and usage patterns. We also service grow-room HVAC systems that require precise temperature and humidity control alongside standard residential and commercial work.
Our approach centers on recommending only the work your system actually needs, with transparent pricing and free estimates provided up front. Lutz Mechanical backs installation work with a lifetime workmanship warranty, so repairs related to how the equipment was installed are covered for as long as you own the property.

How Equipment and Service Come Together
Every HVAC project starts with understanding your current system, your building's layout, and what you're trying to accomplish—whether that's replacing a failing furnace, adding air conditioning where none existed, or improving airflow through updated ductwork. We walk through equipment options, sizing requirements, and installation logistics so you know what to expect before any work begins. Transparent pricing means you see costs in writing, and free estimates let you plan without pressure.
Once installation is scheduled, the work proceeds with attention to code compliance, proper venting, correct refrigerant charge, and secure connections for gas piping or electrical supply. Systems are tested under load to confirm they're operating as designed, and you receive a walkthrough of controls, maintenance intervals, and warranty details before we leave the site.
Our capabilities extend across residential and light commercial applications, supported by Michigan licensing and familiarity with the region's heating and cooling loads:
Furnace, air conditioner, boiler, and mini-split installation sized to your building's heat loss and cooling load calculations
Commercial rooftop unit service for flat-roof applications common in retail, office, and warehouse environments
Grow-room HVAC systems designed to maintain stable temperature and humidity for controlled-environment agriculture
Indoor air quality upgrades including wildfire-smoke filtration, humidifiers, HRVs, ERVs, and UV lights integrated with existing ductwork
