The presence of mold in an HVAC system is a common complaint. Mold can grow…
Because your air conditioning unit is electrically operated, any potential electricity surge could result in considerable damage. As a consequence, during a thunderstorm, it is wise to disconnect your AC unit, first by raising the temperature on the thermostat to stop the unit from running, and then physically disconnecting it from the electricity supply, usually by using the integrated circuit breaker.
Because your main unit is located outside, and costs a fair few bucks, there is always the temptation to protect it with some form of cover. Trust us when we say that these units are designed to withstand external weather conditions, so covering it up can do more harm than good if you forget to remove the cover when using the system. If, after a storm, you find your AC unit is actually in standing water, then you would be best advised to give us a call here at Petrocelli Services and ask us to come out and assist you.
Don’t worry about snow, that will do no harm, though do not run your system if the whole external unit is covered from top to bottom with snow. Of course, storms can lead to flying object, and there is no guarantee that one won’t hit your unit. If you are unduly concerned and keen to provide additional protection, we can advise you on an appropriate type of shelter that will protect the unit while still allowing ample ventilation.
Finally, there is the other end of the scale, and a heatwave. As your unit is outside it will heat up because of the air temperature. At times like this, to keep your home cool, the unit will be working at near to or maximum capacity, which can be a dangerous time. Consider accepting a slightly higher indoors temperature just to give your air conditioning unit a bit of a break.
