Heating and Air Conditioning FAQs, answered by experts

You should plan to change your AC unit's filter every one to three months, depending on the manufacturer's recommendations. You should also clean the coils at least once per year, but if you have pets or someone in your household has allergies, you might need to clean them more often. Fortunately, many pros will clean the coils and change the filter for you during an inspection, which you should schedule once or twice per year.

Yes, ventless portable air conditioners exist, and not all standard portable air conditioners must be vented through a window.

Ventless portable units, often called evaporative coolers, do not have exhaust hoses. They use a water reservoir and a cooling pad to add moisture to the air, making it feel cooler. These units work best in dry climates because humid areas cannot absorb much additional moisture.

For standard portable air conditioners that do require venting, a window is not the only option; they can also be vented through a door, wall, or ceiling. However, it is essential to vent these units properly. Running a standard portable AC without venting it is counterproductive because it needs to expel heat to cool the room. Failing to do so will only increase the room's temperature.

Yes, a dirty evaporator coil can freeze up. Dirty evaporator coils can’t absorb or transfer heat properly. The dirt and grime restrict airflow, which is needed to move heat throughout the system properly. Your air conditioning unit could freeze over, or it can cause your heat pump to freeze.

Here’s the cost formula to find out how much it’ll cost you to run a window air conditioner in your home:  Watts * (hours used) / 1,000 * (Local kWh) = daily cost of running a window unit. If you need help calculating the cost of running your window AC unit, consult an AC repair or installation pro for an accurate estimate.

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.
