Tankless water heaters heat water only on demand, eliminating standby energy loss from keeping a large tank hot 24/7. This can reduce water heating costs by up to 30% in many homes. At Treadwell Mechanical, we help DeWitt homeowners choose correctly sized tankless units for maximum efficiency and endless hot water.

Schedule furnace maintenance in early fall and air conditioner service in late spring before peak demand hits. Michigan's extreme temperature swings place heavy strain on systems, making seasonal tune-ups essential for reliability. At Treadwell Mechanical, we recommend enrolling in an annual plan for priority scheduling and consistent upkeep.

System size, efficiency rating, ductwork condition, and installation complexity all impact cost. Homes in DeWitt and Lansing often require tailored sizing due to mixed home ages and layouts. At Treadwell Mechanical, we provide honest, transparent estimates based on accurate load calculations and your comfort goals.

A furnace generates heat by burning fuel or using electric resistance, while a heat pump moves heat from outdoor air into your home.

Annual flushing removes mineral scale buildup that can reduce efficiency and cause temperature fluctuations. Technicians also inspect ignition systems, venting, and filters during maintenance visits. At Treadwell Mechanical, we provide reliable tankless maintenance and repair for both gas and electric units across the DeWitt area.

Sealing duct leaks improves airflow, balances room temperatures, and reduces energy waste by up to 20%. Older Lansing-area homes often have poorly insulated or leaky ductwork. At Treadwell Mechanical, we use accurate testing to identify loss points and deliver thorough, code-compliant repairs that lower utility bills.

Frozen coils typically result from restricted airflow due to dirty filters, blocked return vents, or low refrigerant levels. Humid Michigan summers can worsen the problem. At Treadwell Mechanical, our licensed technicians diagnose the root cause quickly and restore reliable cooling with honest repair recommendations.

Skipping seasonal maintenance is the most common error, leading to unexpected breakdowns and shortened equipment life. Michigan's temperature extremes demand consistent upkeep.
