In a tropical climate like Hawaii, a reliable AC installation can be a luxurious installation for any home. Naturally, it’s distressing if your unit breaks down easily, raises your energy bills, or simply can’t keep you cool. These signs usually indicate that your unit is short-cycling, which is when the AC constantly turns itself on and off without ever completing an air conditioning cycle, forcing it to do extra work without even meeting your needs. Read on to learn why this happens and how to handle it.

3 Causes of HVAC Short-Cycling

1. Overheating

Your HVAC system needs to stay cool as much as you do. If the system overheats, it will malfunction, leaving it unable to move past the on/off stage. There are several possible explanations for overheating. First, check the air filter. If it’s caked in dirt, dust, and other debris, air isn't able to move through and cool the system. To restore your unit to its ideal operating temperature, replace the old filter with a new one.

However, the problem might be the evaporator coil instead. Without proper airflow, it will freeze and become unable to absorb any heat. It should thaw out if you simply leave your AC system off for a while, but if it freezes again after turning it back on, it's time to schedule an appointment with an HVAC contractor for repairs or a replacement.

Additionally, the refrigerant level could simply be low. This liquid helps the evaporator coil absorb heat and moderate the temperature in your home and HVAC system. Since refrigerant is toxic, it's best to let a professional replenish it.

2. Faulty Wiring

An AC unit has a complex system of electrical wires. Over time, these wires may become loose, frayed, scorched, or corroded. Faulty wiring will prevent your AC unit from receiving the power it needs to complete a full cycle. To avoid injury by repairing it yourself, it's best to ask your contractor to update the wiring and restore your unit's functionality.

3. Wrong Size Unit

If you suspect that your unit is too big for your home after an AC installation, you'll notice that the unit will release a large amount of cool air into the home and then shut itself down, thinking its job is already done. Then it will turn itself back on when your home’s temperature rapidly rises again. The wrong AC unit can cause constant short-cycling.

In this case, your air conditioning contractor will need to replace the unit with one that is more appropriately sized for your home. Consult with them about the options that make the most sense for your needs.
