Common HVAC Questions Homeowners Ask

Answers to Your South Bend AC Repair & Maintenance Questions

Some of the most common AC issues we repair include low refrigerant levels, frozen evaporator coils, clogged drain lines, malfunctioning thermostats, and electrical failures. If your system is blowing warm air, making strange noises, or failing to start, it’s best to schedule a professional diagnosis before the problem worsens.

If your AC is over 10-15 years old, has frequent breakdowns, or requires expensive repairs, replacing the system may be more cost-effective. However, if the issue is minor—such as a clogged filter, faulty capacitor, or thermostat issue—a repair can restore performance. Our technicians will assess your system and provide the best recommendation.

Water leaks are usually caused by a clogged condensate drain line, frozen evaporator coils, or a dirty air filter restricting airflow. If you notice water pooling around your unit, turn off the AC and contact a professional for an inspection to prevent water damage or mold growth.

To maintain optimal performance and efficiency, your AC should be serviced at least once a year. Ideally, schedule spring maintenance before the cooling season starts. Regular tune-ups help prevent unexpected breakdowns, improve energy efficiency, and extend the life of your system.

At All Temp Heating & Cooling, our AC maintenance services include:

  • Cleaning condenser and evaporator coils
  • Checking refrigerant levels and pressure
  • Inspecting and lubricating moving parts
  • Testing thermostat calibration
  • Examining ductwork for airflow issues
  • Cleaning or replacing air filters
  • Tightening electrical connections
  • Checking for leaks and blockages in the drain line

To keep your system running efficiently, follow these steps:

  • Change air filters every 1-3 months to maintain airflow.
  • Keep the outdoor unit clear of debris to allow proper ventilation.
  • Set your thermostat to an optimal temperature (typically 78°F in summer).
  • Use ceiling fans to help distribute cool air more efficiently.
  • Schedule professional maintenance annually to prevent wear and tear.

Unusual AC noises can indicate mechanical issues or loose components. Here are some common sounds and their causes:

  • Squealing – Worn-out belts or motor bearings.
  • Banging or rattling – Loose internal components.
  • Buzzing – Electrical issues or refrigerant leaks.
  • Clicking – Failing thermostat or capacitor.

If your AC is making persistent noises, it’s best to have it inspected before a small issue turns into a costly repair.

Most central air conditioners last 12-15 years with proper maintenance. Regular servicing helps maximize lifespan, while neglecting maintenance can lead to premature system failure.
