Heil AC Repair

Signs your HVAC needs service include: unusual noises, weak airflow, inconsistent temperatures, higher than normal energy bills, frequent cycling, strange odors, and visible leaks or moisture. If your system is over 10 years old and hasn't been serviced recently, schedule a tune-up.

Common causes include: dirty air filter restricting airflow, low refrigerant from leaks, dirty condenser coils, frozen evaporator coils, thermostat issues, or compressor problems. Start by checking and replacing your filter, then call a professional if the problem persists.

Different noises indicate different problems: squealing may mean belt issues, grinding suggests motor bearing failure, clicking could be electrical problems, buzzing might indicate loose parts or refrigerant issues, and banging could mean a loose component. Turn off the system and call for service if noises are severe.
