It’s hard to believe, but the quick answer is YES! There can be ice on your air conditioning unit in the Arizona summer. This is never a good thing, though, and is an indicator of a problem.
Some of the causes of ice on an air conditioner include:
- Low refrigerant. Your air conditioning unit requires refrigerant to operate effectively. It cycles through the coils and valves to cool the air. When refrigerant is low, pressure in the coils drops and ice forms, causing the system to work harder to cool your home.
- Dirty filter. Just as we breathe, so does your home. A dirty air filter is like having an allergy or asthma attack; the air is restricted, causing the coil to drop below freezing. The result is that ice forms and the system is forced to work harder.
- Non-functioning fan. If the fan is not functioning properly, that means air is not being circulated through the ductwork of the home. This can also cause ice to form on the unit.
What can be done to prevent this from happening?
Annual maintenance of the air conditioning unit and entire HVAC system will ensure the system is working properly and efficiently. It is our goal for our customers to enjoy comfortable temperatures in their homes.
Consider joining the Peak Performance Club, where we will perform TWO 51-point inspections, clean indoor and outdoor coils, and clear condensate.
What if you find ice on your air conditioner?
You may see ice on the unit, hear what sounds like ice dropping in the unit, or experience a change in the temperature of your home. If this happens, turn off the unit and call the team at John’s Refrigeration.
We look forward to helping keep your family home clean and healthy.
