Detroit's Great Lakes climate
makes AC harder than most cities.
Southeast Michigan's summer heat indexes regularly exceed 95°F as moisture rolls in off the Great Lakes — your AC must remove both heat and humidity simultaneously, working far harder than in drier climates. Detroit and surrounding cities from Pontiac to Taylor face this every summer.
There's also a Southeast Michigan-specific spring problem: cottonwood. Every May and June, cottonwood drifts from Detroit's parks and tree-lined streets and packs into outdoor AC condenser fins across the region — blocking airflow, burning out fan motors. It's one of the most common causes of early-summer AC failure in Detroit, Warren, Royal Oak, Ferndale, and surrounding cities.
Heat Is a Medical Emergency: Detroit officially classifies extreme heat as a leading weather-related cause of death. For elderly residents, infants, and people with heart or kidney conditions in any of our service cities — a broken AC during a heat dome is dangerous. ABBCO prioritizes these calls. (910) 304-7218
AC symptoms —
what's actually wrong.
- AC runs but house won't cool — frozen coils, low refrigerant, or failing compressor
- AC won't turn on at all — failed capacitor, blown fuse, tripped breaker
- Running constantly, huge DTE bill — low refrigerant or dirty condenser coil
- Grinding from outdoor unit — compressor beginning to fail. Expensive. Gets worse fast.
- Ice on AC lines — turn it off and call us. Running an iced unit destroys the compressor.
- White fluff around outdoor unit (May–June) — cottonwood. Rinse with garden hose now.

FAQ — AC repair in Southeast Michigan
