In these hot months, you may have had your air conditioning running none stop. To help expand it’s lifespan and keep it’s efficiency up, give it some resting time. You can usually find how often and for how long you should let your air conditioner rest in it’s manual/guide.
As we’ve stated many times before, it is good to have your furnace and/or air conditioner inspected & serviced at least once a year. So if you don’t remember the last time you had someone in, perhaps now is a good time!
The key to being cool and comfortable has a lot to do with humidity. If a window air conditioner is too large for it’s room or space, too many BTU’s, then it may cool the room but fail to remove the humidity properly.
