Probably not. Modern comfort control systems are usually equipped with surge protection. In the event of lighting, however, it’s never a bad idea to turn off your air conditioner and unplug appliances.

Check your filter at least monthly and clean and replace as needed. A dirty air filter limits air flow, which can cause the compressor to run longer, cause the heat exchanger to overheat and increase utility bills up to 20 percent or more.

  • Have the air vents in your home balanced, set the thermostat on as high a temperature as possible while still remaining comfortable, and then leave the two alone. Constant adjustment can eat up a lot of electricity.
  • If you’re away from home at certain regular periods throughout the week, invest in a programmable digital setback thermostat that will raise and lower temperatures automatically in relation to when you are home and away from your house.
  • Don’t set your thermostat any lower than the desired temperature when you turn on your air conditioner. Cranking down the thermostat will not cool your home any faster and wastes energy.
  • Check your air filter at least monthly and clean or replace as needed. A dirty air filter is the No. 1 cause of inefficient operation and high power bills.
  • Keep debris and other obstructions well away from the outdoor fan to allow sufficient airflow and maximize efficiency.
  • Ceiling fans can help circulate and even-out the cool air inside the home.
  • Move lamps, televisions and other warm appliances away from your thermostat.
  • Plant trees and shrubs to shade the outside unit, but so as not to obstruct the fan. Shaded air conditioning units more effectively cool and can use as much as 10 percent less electricity.

H.S.P.F. stands for Heating Seasonal Performance Factor, and is a measure of a heat pump’s heating performance, not unlike the MPG of an automobile. The minimum required H.S.P.F. rating is 6.8, with some manufacturers producing units with a rating of 10 or higher. The more efficient the system, however, the higher the cost.

SEER is an acronym for Seasonal Energy Efficiency Ratio, and is a measure of the performance of the system, not unlike the MPG of an automobile. The higher the SEER, the better the efficiency. The lowest SEER rating allowed is 14, and some manufacturers produce units with SEER ratings of more than 20. The more efficient the system, however, the higher the cost.

A digital setback thermostat is a programmable thermostat designed for people with fixed schedules that take them away from their homes for periods of time. If you leave for work at 8:00 a.m. each weekday and return at 5:00 p.m., for example, you can program a digital setback thermostat to automatically raise the temperature in your home to save on power while you’re out.

We’ll inspect several key areas—including ductwork, insulation, refrigerant piping, electrical service, wiring, thermostat, condensate piping and more—and determine what is salvageable and what is not.

A myriad of cooling and heating factors will alter the percentage of power used by your air conditioning system relative to other electric appliances in your home. However, on average, about 44 percent is typical.

The average lifespan for a high-quality cooling and heating system is 8 to 12 years, depending on amount of use, climate in which it operates and whether or not the system received regular preventive maintenance.

The criteria for determining repair or replacement is how much of a repair bill you’re faced with today; how long can you expect before other problems arise based on the age and condition of your system; the cost of a replacement system; and what advances in technology and efficiency have manufacturers made since the installation of your current unit. Today’s systems are as much as 60 percent more efficient than those manufactured just 10 years ago. The savings in efficiency alone might be enough of a return on your investment to replace now instead of enduring another season of costly repairs.

There’s, of course, no absolute right answer, but the experts at John C. Cassidy can help you make an educated, informed decision.

According to EPA, indoor air pollution can be as much as 100 times higher than outdoors. However, by scheduling regular professional preventive maintenance by John C. Cassidy Air Conditioning, you can ensure the highest air quality possible and always breathe easy.

The air handler circulates the air conditioned by the cooling and heating unit and is usually where filtration and dehumidification takes place.

An air conditioner that is too large for the area it’s meant to cool performs less efficiently and effectively than a smaller properly sized unit because the oversized unit will tend to run more often for shorter lengths of time, which is less effective at removing humidity. Longer run times allow the system to maintain a more constant room temperature.
