Replace your filter about a week before your scheduled tune-up so our technicians can see how your system runs with a clean filter and check airflow properly. Many Humphrey Avenue homes have older ductwork that can get dusty over Michigan winters, so a fresh filter helps us get accurate readings. We'll also show you the right filter type for your specific system during the visit.

Birmingham follows Michigan mechanical codes, so minor refrigerant top-offs during routine maintenance don't need permits, but any refrigerant line repairs or system component replacements do require permits. We handle all Birmingham permit applications and inspections for you if repairs are needed. Most spring tune-ups on Humphrey Avenue don't require any permit work unless we find damaged lines or components.

Listen for unusual grinding or squealing noises from your outdoor unit, especially when it first starts up after sitting idle through Michigan's winter. Watch for ice buildup on refrigerant lines during spring test runs, or if your system runs constantly but doesn't cool effectively. Birmingham Plumbing catches most compressor issues during spring maintenance before they become expensive summer emergencies.

Many homes along Humphrey Avenue were built in earlier decades with ductwork that settles and develops leaks over harsh Michigan winters. We commonly find disconnected joints or damaged ducts in crawl spaces and basements that reduce cooling efficiency. Spring is the ideal time to seal these issues before summer heat puts extra strain on your system.
