Tips During Heat 🥵 Wave:
✔Air Conditioners are designed to cool 20-30 degrees lower than the outside temperature. Trying to get your house to 65-67 when it is 100-105 will be challenging during the high heat of the day and will be costly on your electric bill.
✔ Keep blinds closed during the day.
✔ Make sure your filters are clean.
✔ Keep all your floor registers open, the equipment is designed for them to be open in some degree.
✔ Turn ceiling fans counter clockwise direction.
