While enduring a grueling summer, many homeowners do not think there is such a thing as ‘too cool.’ An indicator that there is a problem, unfortunately, is the air conditioner frosting over. It is a problem that needs to be rectified as quickly as possible when it comes to the air conditioner frosting up. The air conditioner freezing over is something that we at Hal Mechanical would like to discuss today.
How to Tell if AC if Frozen
In quite a few cases, a homeowner might not know that the problem of an air freeze. Where sometimes it is as obvious as a bunch of puddles on the ground, literal ice formations on the unit to its evaporator coils. In some cases, the cause is more subtle, where others make it more obvious. Below we have listed less obvious signs that provide an option to assist you in order to help prompt you for further investigation.
– Condensation surrounding the indoor AC
– Adequate temperatures are not reached
– Abnormal sounds coming from the unit
– A short cycling system or one that shuts off early.
– Discovering puddles around to outdoor unit
What Causes Air Conditioner to Freeze Up?
The system getting too cold can stem from many issues. A professional repair is required when some sources can be easily rectified yourself and other situations.
1) Leaking / Low Refrigerant. A common misconception is that the A/C will use up refrigerant. The evaporator, the condenser, and the compressor are the three components to the cycle. At all times, refrigerant cycles and is never used up. It is likely a leak is present, or less likely that at the time of installation, the technician didn’t charge it in the event the unit is not fully charged with refrigerant. Because the air conditioner will attempt to operate as normal, even without the refrigerate, causes it to freeze. Since it is a critical part of the cycle is the refrigerant compressing and reaching extremely high temperatures, when there’s no refrigerant, the system will begin to accumulate too much cold, leading to ice.
2) Airflow Difficulties. An air conditioner requires very precise air pressure levels, as this why you should not close vents, and a healthy air flow in order to operate effectively. When air flow is restricted, it depressurizes the unit, basically suffocating it and causing excessive buildup of cold. The following can be indicators of weak airflow.
– Wrong air filter. Take advantage of HEPA-grade air filters in your AC. Though there are a few exceptions, they are not usually used for home but often rated for commercial equipment.
– Dirty Air Filter. Make certain to replace your filter frequently, once every month or two should be good in order to promote healthy airflow. An efficiency boost, the HVAC system is given.
– Obstructed Return Ducts. Vents need to be clean and free of debris, to remain unblocked at all times.
– Neglected AC Maintenance. A system that doesn’t get an AC tune-up frequently enough will build up tons of dust, grime, and debris, it will choke your system in no time. Do not avoid annual maintenance.
