Frequently Asked Questions

A lifetime workmanship warranty covers labor and installation defects for as long as you own the property. If ductwork connections fail, refrigerant lines develop leaks from improper installation, or electrical connections cause system issues, the installer returns to correct the problem at no charge. Equipment component failures are handled separately under manufacturer warranties.

If your furnace is under 12 years old and the repair costs less than one-third of replacement price, repair usually makes sense. Heat exchanger cracks, repeated control board failures, or compressor issues in systems over 15 years old typically justify replacement. Efficiency improvements and avoided future repairs often offset replacement cost within five to seven heating seasons.

Modern cold-climate mini-splits operate effectively down to -15°F and below, covering most Michigan winter conditions. Heat output drops as outdoor temperature falls, so sizing must account for your coldest expected days. Homes in Bath and Mid-Michigan often pair mini-splits with existing heating as backup or use wall-mounted units in additions and spaces without ductwork.

MERV 13 or higher filters capture smoke particles between 0.3 and 1.0 microns, which includes most wildfire pollutants. Whole-home air cleaners with HEPA-grade media provide the most thorough removal, while standard furnace filters rated MERV 8 miss finer smoke particles. Upgrade filtration before smoke season and check filters weekly during active smoke events—they clog faster under heavy particulate load.

Boiler maintenance confirms safe combustion, tests pressure-relief operation, inspects heat exchangers for cracks, and verifies circulator pump function. Sediment buildup reduces heat transfer and overworks the system, while delayed combustion from dirty burners creates safety risks. Annual service before heating season prevents mid-winter breakdowns and catches developing problems when repair scheduling is easier.

Ductwork leaks, undersized or blocked supply vents, closed dampers, and improperly balanced airflow all create hot and cold spots. Zoning systems with separate thermostats solve layout-driven temperature differences, while duct sealing and airflow balancing correct distribution issues. Single-stage equipment struggles to maintain even temperatures in homes with varied sun exposure or insulation quality.

HRVs exchange heat only, transferring warmth from outgoing stale air to incoming fresh air during winter. ERVs transfer both heat and moisture, preventing excessive indoor dryness in winter and reducing humidity infiltration in summer. Michigan's humid summers and dry winters often make ERVs the better choice for year-round comfort and controlled fresh-air exchange.

Technicians inspect curb mounting and flashing, check refrigerant charge, clean condenser coils, test economizer dampers, verify belt tension, and inspect drain pans for rust or clogs. Rooftop exposure accelerates wear from weather and UV damage. Seasonal service before cooling and heating modes prevents failures during business hours when downtime affects operations.

Adding central AC requires installing an outdoor condenser, indoor evaporator coil, refrigerant lines and electrical circuits. If existing ductwork is properly sized and sealed, the installation integrates with your furnace's air handler. Undersized or leaky ducts reduce cooling performance and efficiency, so duct evaluation should happen before equipment selection.

Visible soot inside the furnace cabinet, rust spots on the heat exchanger, flickering yellow burner flames instead of steady blue, and the smell of formaldehyde or combustion gases indoors all indicate potential cracks. Carbon monoxide detectors may alarm if exhaust enters living spaces. Heat exchanger failure typically requires furnace replacement since the part costs approach new equipment pricing.

Grow rooms generate intense heat from lighting, require precise humidity control to prevent mold, and need consistent temperature to avoid plant stress. Standard residential equipment can't handle the latent cooling load or provide the tight tolerances most crops demand. Properly sized dehumidification, staged cooling, and automated controls maintain the stable environment high-value crops require throughout growth cycles.
