Grounded outlets and GFCI-protected outlets (short for Ground Fault Circuit Interrupters) have been required by the National Electric Code (NEC) for a number of years.The purpose of both grounding and GFCIs is to improve the safety of a home’s electrical system.
GFCI-outlets are required in kitchens along countertops, in bathrooms, outside, in garages (except on dedicated outlets such as for the garage door opener, a freezer, etc.), and around pools and hot tubs. Some people have the mistaken idea that they are the same thing as a circuit breaker. This is not the case at all.
SEER stands for Seasonal Energy Efficiency Ratio. SEER is a rating system that was devised to provide a way to determine the relative operating cost of an air conditioning system or to compare the energy efficiency of air-conditioning systems. The SEER rating is calculated by dividing the cooling output during a complete cooling season by the energy used to achieve that cooling.
With the year 2020 just days away, it is important to keep in mind some changes that are coming to your home air conditioning system – at least if you own a system that uses R22 refrigerant.
