"My dad always told me to have "a guy" for everything, and Ben is definitely my guy for HVAC. He was so kind, punctual, and helpful. He explained everything thoroughly, and gave me options that the big company wouldn't even mention. I have already sung his praises to multiple friends and family."

Heating and Air Conditioning questions, answered by experts

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, you can clean your air conditioner filter as a temporary fix for cleaning up dirt, but you’ll eventually need to replace it once the dust starts to accumulate. Use a vacuum with a hose attachment to clean your air filter at least once per year or more often if you have pets.

One of the fastest ways to unfreeze an AC unit is to turn off the unit and, if it’s warm outside, use the fan-only mode to help blow warmer air through the unit to speed up the defrosting process. While it may be tempting to use a hair dryer to defrost the air conditioner, that high heat can damage the coils.

After defrosting, if you can safely solve the issue with a fix like changing the filter, go ahead and do so. Otherwise, call in a pro before turning your AC back on.

If there’s a freon leak in your home’s AC unit, it will cause the system to work overtime to cool the house. That issue will result in higher energy bills and it will take much longer for cool air to disperse throughout the home. If your system has a freon leak during the summer, it can make hot days miserable. That’s why it’s important to hire an HVAC professional to resolve a freon leak as quickly as possible.

You should know the main components of an air conditioner: the condenser coils, evaporator coils, drip pan, AC filter, ducts, and refrigerant. Each part plays a key role in the performance and safety of your AC system. When tracking the source of AC issues or odors, it helps to know where to look. Your outdoor unit houses your condenser coils, fan, and compressor. Your indoor unit houses your evaporator coils, drain lines, and filter, and it connects to your ductwork.
