The rain doesn’t get inside your unit, unless you have let the outer case rust through or have otherwise perforated it.Any moisture that come in through the air intake will be extracted by a filter, before reaching the cooling coils. Even if moist should hit the coils, at the very worst it would freeze up, eventually encasing the coils in frost. Then your unit would be working harder, and cooling the incoming air less.All of that would go away by leaving the unit Off for a few hours.Written Yes, this is pretty much a given. Here are the only cases where I this would not be true.A portable unit(dryer type vent) running outside in an uncovered area where rain can hit it.A window unit not in an actual window but 100% outside like in the above case.In these cases, it is subject to the same rules as other electrical appliances.In the 1970s, The Carpenters wowed us with a beautiful song about 'Rainy Days and Mondays'.

No one likes to be uncomfortable; we're in agreement with that. During air conditioning season our phones ring 'off the hook' with dozens of calls pouring in every day...long-time customers and new prospective clients requesting service for their ailing air conditioners. And, we want to help...but Mother Nature sometimes has other thoughts in mind. Safety first...there is no doubt about that. Your expert local air conditioning service company  wants to take care of your needs; however, working on electrical equipment in the rain can not only jeopardize the safety of the HVAC technician, but can cause damage down the road to your system. Let's face it, water and voltage just don't mix well together! How can you survive during hot weather and a storm when you cannot get immediate service for your ac unit? Turn your system off at the thermostat. It makes no sense to have an cooling system, that is not functioning properly, run only to further cause problems with the system.

If your system is low on refrigerant, it will 'freeze up' causing damage to the componenents and a delay when your air conditioning tech arrives. Open windows that will create cross-ventilation so that you have air circulating through your home. If you have ceiling fans, use them.

When installed properly, window air conditioners fill the space at the bottom of a window snugly. Window air conditioners make a welcome addition to any room in need of cool air during hot-weather months, but if gaps or holes develop around the unit, rainwater can seep inside and cause damage to a home in the form of wood rot and possible mold growth on surrounding surfaces. If you notice water marks on the wall below an air conditioner, or see puddles on the floor nearby, look for the source of the leak and fix the problem immediately. Inspect the air conditioner from all angles to make sure that it's installed properly. There must be no gaps between where the window and window frame come in contact with the top and bottom of the air conditioner, or where the air conditioner's side panels meet with the sides of the window frame. Adjust the air conditioner to close any gap. Make sure the air conditioner is aligned and balanced properly on the window, and that the window's bottom sash is tightened securely to the top flange of the air conditioner with at least two screws.
