HVAC Maintenance in Michigan: What Homeowners Should Do Each Season

For most Metro Detroit homes, the best maintenance rhythm is a cooling-system check before hot weather and a heating-system check before cold weather, plus regular filter checks throughout the year.

Spring: prepare before the first heat wave

Replace or inspect the filter, clear debris around the outdoor condenser and test cooling before the hottest week of the year. A professional visit can evaluate electrical components, airflow, coil condition, drainage and operating temperatures.nnTesting early matters because a system that barely worked at the end of last summer may fail when outdoor temperatures climb and service demand is highest.

Fall: verify safe, dependable heat

Before winter, heating equipment should be inspected for safe operation, venting, ignition, combustion-related concerns where applicable, blower performance and thermostat control. Boiler systems also deserve attention to pressure, pumps, valves and zone operation.nnHomeowners should never ignore unusual odors, soot, repeated shutdowns or carbon-monoxide alarms.

All year: watch the clues your home gives you

Filters, humidity, unusual noises, changing utility use and room-to-room temperature differences can reveal problems before a complete breakdown. Keep outdoor equipment clear, avoid blocking returns and note when the system starts running differently than it did before.nnMaintenance does not guarantee that equipment will never fail. It does create opportunities to catch wear, drainage problems, airflow restrictions and control issues earlier.
