Signs Your AC Needs Repair

If your air conditioner isn’t adequately cooling your home, you may need a professional repair. Here are the most common signs your AC needs immediate service:

  • Unexplained increase in your cooling costs: If your energy costs are rising, it may indicate your system isn’t operating efficiently or effectively.
  • AC isn’t cooling properly: If your AC is blowing hot air or not cooling your home effectively, there could be a problem with your filter, refrigerant, or compressor.
  • System is short-cycling: If your AC cycles on and off frequently, it’s a sign that there’s a problem, such as frozen evaporator coils or a system that isn’t properly sized for your home.
  • System is producing odors: Unusual smells from your AC can indicate various problems, including mold growth and Freon leaks.
  • AC is making new or unusual sounds: Any grinding, banging, or whistling sounds are all signs you need a professional inspection and repair.

The company scheduler was very helpful and got us a same day appointment. Matt, the technician was very prompt and professional and even provided advice on the issue. The price was reasonable even though the technician traveled from Maryland to our home in Martinsburg WV. I would recommend Larry and Sons for plumbing repairs to anyone.
