If it’s the middle of summer and your air conditioner freezes up with its coils covered in ice, turn the unit off. The next step is to call us for a service call to diagnose the problem. It may be relatively easy to fix, but if left alone, serious problems will soon develop. Air conditioner freeze up can happen due to.

  • Insufficient airflow
  • Low refrigerant levels or refrigerant leak
  • Faulty thermostats
  • Improper fan operation

These problems require a qualified technician to diagnose and repair them. Without repair, you may soon be paying for a totally new air conditioning unit (not a bad deal, since modern air conditioners are pretty amazing, but not an expense you want to be blindsided by).

Air Filter Replacement and Air Conditioner Maintenance

Air conditioners need proper airflow to run smoothly. Dirty air filters and closed registers mean they have to work harder. Filter replacement and other regular maintenance tasks can add years to the life of your AC. During an annual maintenance visit our technicians check refrigerant levels, clean and lubricate mechanical parts and inspect the entire system.

WeCare Protection and Maintenance Plans Prevent Problems

A WeCare Protection or Maintenance Plan is one of the best ways to keep your air conditioner from freezing up. Dunn Heating service technicians make sure your heating and cooling system gets the proper care at the proper time. With regular maintenance done the right way, the chances of air conditioner freeze up are greatly reduced. If there ever is a problem, with a WeCare Protection Plus plan, there won’t be a charge for a service call. Repairs are included.
