Heating and Air Conditioning questions, answered by experts

An air conditioner’s watt usage depends on multiple factors, including the type of AC unit, its size, and how often you use it. With that said, most central air conditioners consume between 3,000 and 3,500 watts. Meanwhile, window AC units use 900 to 1,400 watts, and portable air conditioners consume 2,900 to 4,100 watts.

You might notice that your air conditioner isn’t running as effectively as it once did. Specifically, your AC unit could take longer to cool your home, or it might struggle to remove humidity from the air. Higher utility bills and hissing sounds coming out of your AC could also indicate a leak.

Yes. In fact, not only are AC tuneups worth it, but they’re actually necessary to keep your air conditioner in good condition, improve its efficiency, and potentially prevent major damage. Experts recommend getting a tuneup at least once per year. In most cases, you’ll want to schedule it during the spring so that you can address any issues before the hottest months of the year.

A dual evaporator coil is a specific design that allows the AC system to cool different compartments at different levels. It’s usually seen in refrigerators and similar appliances, but not in whole-house air conditioning systems. Talk with your AC technician about the best uses for a dual evaporator coil.

A window AC unit is not completely silent. You’ll hear the sound of air blowing, and if you put your ear right up next to the unit, you may hear a slight hiss or gurgle as the refrigerant flows through the system. That said, if your system is making a running water sound, a loud banging sound, a grinding sound, or physically vibrating, you may be facing an issue or malfunction with your AC unit.
