How To Address A Short Cycling Air Conditioner

How To Address A Short Cycling Air Conditioner
Air conditioning units that turn on and off rapidly within minutes are said to be short cycling. While an HVAC system that does not turn on at all usually claims the top spot for air conditioner frustrations, a system that constantly switches on and off can come pretty close to testing your patience.
Short cycling is extremely detrimental to the lifespan of your A/C unit due to the immense wear and tear the stop and go effect can cause. There are a variety of reasons that short cycling can occur, with some easier to address than others. Even if you find that your A/C unit cools effectively despite short cycling, determining the root cause of your issue and addressing it can significantly increase your energy efficiency and reduce the likelihood of needing repair or replacement.

Maintenance Checkup
Routine professional HVAC maintenance can head off many common problems, but it can be particularly useful in cases of short cycling. While a technician performs maintenance on your system, mentioning your concerns about recent or chronic short cycling can get you to the bottom of the problem quickly. A technician will usually be able to determine if component issues are causing your short cycling problem, and explain how best to address them. Your HVAC maintenance visit is a valuable tool that could potentially offer insight into the cause of short cycling without the cost of an additional diagnostic visit.

Bigger Is Not Always Better
A common mistake many homeowners make is assuming purchasing the larger and more powerful HVAC systems are the best investment for their home. While it is true that more powerful A/C units will cool down your home faster, they fail to properly dehumidify the air and will result in frequent short cycling as they battle to stay at the ideal temperature. Rapid cooling for some homes can also result in significant temperature differences between rooms, with some being too hot and others too cold.

Common Short Cycling Causes
By far the most common cause of short cycling is the buildup of ice on your evaporator coils. This is fortunately not only easy to address but will be detected during the course of any HVAC maintenance visit performed by a professional. Another common cause of short cycling is the overheating which leads to frequent shutdown. This may be the result of low levels of refrigerant, a dirty air filter, or any blockages that are putting excess strain on your system’s components.

Keeping your HVAC system functioning at its best can be difficult when you are dealing with chronic short cycling. Most short cycling problems are easy to address and can even be caused by a malfunctioning thermostat. Regular HVAC maintenance is your first line of defense against short cycling and can tip you off to potential issues in advance.
