Whether trying to keep warm in the winter or cool your home in the summer, few things are more disconcerting than when your heating and air conditioning system unexpectedly shuts off. This typically occurs when your unit is trying to protect itself from overheating, and is more common than you might think. As the team at Mill Creek Heating in Turner, OR explains, there are three primary culprits behind this problem.

Top 3 Reasons Why Heating and Air Conditioning Units Shut Off Unexpectedly

1. Inadequate Ventilation

For outdoor heating and air conditioning units, a lack of ventilation can create serious problems. Shrubs, fences, and other objects that are placed too close to the unit will keep the compressor from releasing heat. In general, you should try to keep anything that might block the unit’s airflow at least 18 inches away.

2. Dirty Air Filter

Changing your air filter on a regular basis is a fairly simple maintenance task — but this doesn’t make it any less important. Over time, the dust that collects on your system’s air filter will restrict airflow through your home’s duct system. This forces your unit to work harder than it normally would, which can easily cause it to overheat or break down entirely.

3. Refrigerant Leaks

Your air conditioner won’t work as quickly if the refrigerant is leaking, and this can shut down your unit and contribute to other serious maintenance problems. The formation of ice on the outside unit is one of the top signs that you’re dealing with a leak, rather than other maintenance issues.
