"My technician Keith was great. Friendly and super informative. Also too a quick look at the entire drainage system and gave my an idea of where problems will pop up the future without preventative measures (my home was built in the 50s and while the previous owners took really good care of the house nothing has been gutted and replaced yet)."

Heating and Air Conditioning FAQs, 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.

Many factors affect how much adding air conditioning will cost you, from the size of your home to the size, type, brand, and installation specifics of the system itself. Chances are, a new central air conditioning system for a 2,000-square-foot house will cost somewhere between $3,900 and $7,900 to install, with an average around $6,000. 

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.

To make the most out of your AC, consider implementing the following best practices: 

  • Choose the right size AC for your home to ensure your unit runs as efficiently as possible.

  • Choose a window with shade, as direct sunlight can cause your AC unit to overheat. 

  • Clean or replace the filter at least every two months. 

  • Inspect the AC’s fan and straighten it if necessary. 

  • Discontinue use immediately if you suspect a malfunction, as running the AC while broken can lead to significant issues. 

  • Turn off (or adjust the temperature) when you leave the house.

If refrigerant levels are low, it can cause the evaporator coil to freeze up. Low freon causes a drop in pressure, which will make the coil too cold and cause moisture to freeze on the coil. Your system may be low on refrigerant because of a leak. 

Make sure to have maintenance performed twice a year, and contact your local HVAC technician if you suspect your system has low freon levels.
