Many homeowners wonder if they should run their air conditioners when no one is in the house. You may have heard that your air conditioner has to work harder to cool down a home that has heated up in your absence. This is true, but that doesn’t mean turning off the cooling system is always a bad idea. Here’s everything you need to know about turning off the AC to reduce energy costs.
Full Speed Equals Peak Efficiency
Your central air conditioning unit will have to run full blast when you return and turn it on in an uncomfortable hot home. However, the equipment operates at its best efficiency in this situation. Everything about the machine is designed to strip heat and humidity from the air. The fan moves hot air out of your home and takes it to the evaporator coil. The refrigerant within the coil absorbs the heat energy in the air, which converts the liquid refrigerant to a gas. As the heat is pulled from the interior air, the blower moves the cooled air back into your rooms.
The system sends the heated refrigerator out to the compressor. In that location, the outdoor fan distributes heat energy into the exterior air while the compressor pressurizes the refrigerant and eventually returns it to a liquid state. When your AC is maintaining your selected temperature, it executes this same process, but there is far less heat energy in the air to be processed. As a result, the fans and compressors are running and consuming energy while only accomplishing small temperature adjustments. The continuous on-and-off cycles used to prevent the temperature from rising above the thermostat setting actually place the most strain on your system.
AC Maintenance Supports Energy Efficiency
Normal wear and tear gradually reduce the operational efficiency of your air conditioning system. Technicians from Cardwell Heating & Air Conditioning in Cherry Hill, NJ, can tune-up your AC. We clean and lubricate moving parts, check refrigerant levels, and replace any parts on the verge of failure. Seasonal maintenance ensures that your equipment runs as efficiently as possible. Power consumption will remain under control, and the cool air will flow when you need it.
When your AC fails, our team can also complete repairs or install a replacement system. We’re trained and licensed to work on central AC and ductless air conditioning.
Manage AC With a Programmable Thermostat
Since turning off your air conditioning when away saves on power, you’ll benefit from the addition of a programmable thermostat. You can schedule AC to turn off after you leave the house and turn back on right before you return from work. With a programmable thermostat, you don’t have to enter a home that has been warming up all day. You get to come home to a freshly cooled home while avoiding the expense of running the system for hours when no one is there.
What to Do on Vacation?
If deactivating the air conditioner while you’re gone for the day saves money, then leaving it off during your whole vacation would save even more money. Although this is correct, you may want to consider how hot and humid it will be while you’re traveling. If very humid weather is likely during your vacation, leaving the AC on will protect your home from moisture buildup. Too much interior moisture could trigger mold growth.
When you factor in potential humidity, it will make sense to leave the air conditioner on. Once again, a programmable thermostat will manage energy consumption. You could set it to maintain a higher temperature than you normally would, such as 78 degrees. This temperature may be higher than you would find comfortable, but it will prevent excessive humidity. The higher temperature setting also cuts back on power usage because AC consumes about 3 percent to 5 percent less energy for every degree that you increase the thermostat setting.
