generator maintenance Ann Arbor

Heat pumps are the future of home comfort—and CMR Mechanical is Ann Arbor's leader in heat pump technology. Whether you need a new hybrid heat pump, a Mitsubishi mini split, or a geothermal system, our certified technicians handle it all. Heat pumps work by moving heat instead of generating it, which makes them up to 300% more efficient than traditional furnaces. That means lower utility bills and a smaller carbon footprint for your family.

Our process starts with a free in-home assessment. We evaluate your space, insulation, and current ductwork to recommend the perfect heat pump size and type. For homes without ducts, we install whisper-quiet mini splits that offer zoned comfort. During installation, we respect your property and finish on schedule. If your existing heat pump needs repair, our 24/7 emergency service gets you back up and running fast. We service all major brands, including Trane, Bryant, Carrier, and Mitsubishi. Choose CMR for heat pump expertise that saves you money year-round.

When your furnace quits on a freezing Ann Arbor night or your AC fails during a summer heatwave, CMR Mechanical is here 24/7. We repair, replace, and maintain all makes and models of furnaces and air conditioners. Our technicians are trained in the latest high-efficiency systems, including gas furnaces with AFUE ratings over 95% and AC units with high SEER ratings for maximum energy savings.

We start every repair with a thorough diagnostic to find the root cause—not just the symptom. If replacement makes more sense, we help you choose the right system for your home and budget. Our installation team works quickly and cleanly, often completing a full replacement in one day. We also offer affordable maintenance plans that include seasonal tune-ups, filter changes, and system inspections. Regular maintenance prevents breakdowns, extends equipment life, and keeps your warranty valid. For reliable heating and cooling in Ann Arbor, trust the family-owned team that puts honesty first.

Did you know indoor air can be five times more polluted than outdoor air? CMR Mechanical helps Ann Arbor families breathe easier with advanced indoor air quality (IAQ) solutions. We install whole-home air filtration systems, humidifiers, and the RGF Halo LED purification system. These technologies capture dust, pollen, mold spores, and even viruses—creating a healthier environment for allergy sufferers and everyone else.

Our process begins with an IAQ test to measure humidity levels, particulate counts, and VOCs. Based on results, we recommend a custom solution. For dry winters, a whole-home humidifier adds moisture to protect your skin, sinuses, and wood furniture. For summer allergens, a high-efficiency air cleaner traps particles as small as 0.3 microns. The RGF Halo system uses UV light and catalytic oxidation to neutralize airborne and surface contaminants. We also offer duct cleaning to remove years of built-up debris. Breathe better with CMR’s indoor air quality expertise.
