7 Common Signs You Need Air Conditioning Repair

Addressing issues with your air conditioning unit sooner rather than later is crucial to prevent minor problems from turning into major, costly repairs. Regular inspections can identify potential issues early, ensuring your home remains comfortable and your AC system operates at peak efficiency. Failure to do so can result in increased energy costs, decreased cooling efficiency, and potentially a complete system breakdown.

Inconsistent temperatures: Some rooms in your home are colder than others.
Strange noises: There are sounds like grinding, squealing, or rattling coming from your AC unit.
Unpleasant odors: Foul or pungent smells are coming from your AC system.
High humidity levels: Your home feels humid.
Frequent cycles: Your AC unit is cycling on and off throughout the day.
Water leaks: Water is pooling around your AC unit.
Increased energy bills: There was a significant increase in your utility bill without a corresponding increase in usage.

If you notice any of these signs, it's important to schedule an AC repair service with Heritage Heating & Cooling as soon as possible.
