Summer is coming. Before it gets hot, you might want to check that you and the house are ready for the summer heat.
That means you start by checking your home's heat and air-conditioning system.
To begin, change your filters in your heating/cooling system. Change them regularly - at least monthly.
Next change your thermostat over to "cool" and test the system by turning the temperature down. If the air conditioner does not turn on, first check to make sure no breakers are tripped. If you can't figure out the problem, call your heating and air-conditioning repair person. Calling early may keep you from making an "emergency" call when the temperatures are soaring and the repair people are super busy and expensive.
If your cooling system turns on, make sure it is putting out adequate cooling. If it's not, and you can't figure out the problem, call your heating and air-conditioning repair person. Set the thermostat at 78 degrees.
If your air conditioner needs replacement do it before the hot weather hits so you’re not wilting because the heating & air-conditioning repair people are very busy. And more than likely, some other things around your home might need attention as well.
Your air ducts may need testing for leaks and then sealed. Your attic insulation probably has compacted, so you need to add an additional 5 to 8 inches. Your windows and doors and other parts of the building envelope may need caulking and weather stripping. Think about solar window film to keep out the heat.
