The air handler in your air conditioner moves the cool air through your home, and a malfunction means you get reduced airflow and no cold air. If you’re not getting all the cold air you used to get, it could be a problem with the air handler. Call the experts at Alberta Indoor Comfort (previously Sears) for fast, accurate repairs.

Proper Air Handler Maintenance
To keep your air conditioner running smoothly and keeping your house cool, it’s essential you maintain your system, and one area to watch out for is the air handler. To keep your air handler functioning optimally, clean it regularly with a vacuum and make sure your air filters are clean. This maintenance is best performed by a trained technician.
