Is Your Air Conditioner Showing These Warning Signs?

If you notice any of these common issues, our Shepard Drive service trucks are already in your area and ready to help:

• Air Conditioner Blowing Warm Air: Usually points to a failed start/run capacitor, dirty outdoor condenser coils, or a refrigerant leak.

• Weak Airflow from Vents: Caused by severely clogged air filters, damaged ductwork, or a failing blower fan motor.

• Grinding, Squealing, or Banging Noises: Signals mechanical wear or loose motor components that require immediate attention before total compressor breakdown.

• Water Leaking Around Indoor Unit: Indicates a clogged condensate drain line or cracked drain pan that can cause major ceiling or floor damage.

• Frequent System Short Cycling: Turning on and off rapidly, signaling electrical faults, improper unit sizing, or low refrigerant levels.

Proactive AC Maintenance & Modern System Upgrades

Preventative maintenance is the single best way to avoid costly mid-summer breakdowns, reduce electric bills, and extend the operating lifespan of your unit. Protect your investment with our Polar Comfort Maintenance Agreement for annual tune-ups, priority emergency dispatch, and repair discounts!

Signs It’s Time to Replace Your Old Air Conditioner:

• System Age: Units over 10–15 years lose significant efficiency and become prone to motor failure.

• Uses R-22 Refrigerant: R-22 has been phased out due to environmental regulations. Sourcing R-22 for repairs is extremely expensive, making a modern R-410A / R-32 system replacement far more practical.

• Rising Energy Costs: Upgrading to a modern high-SEER2 Carrier® system can reduce monthly summer cooling costs by up to 30%.
