"The semi-annual checkups were OK as was the emergency repair work they did. But after we had a new HVAC system installed and no longer needed our contracts with them they failed to honor our written request to return the requested balance remaining on our contracts."

Heating and Air Conditioning questions, answered by experts

No. With a ventless portable AC system, you don’t need to vent anything out the window—but it will be harder to circulate the hot air from the room without one, so you’ll need to come up with another solution, like placing a fan near a warm spot and facing it towards and open water to push the hot air out.

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.

Replacing both an AC and a furnace takes a full day on average, ranging from eight to 12 hours. The process involves removing the old units, installing the new ones, and ensuring all connections are properly made. If both systems are being replaced simultaneously, it can take longer than installing a furnace alone, so plan accordingly.

A home AC unit provides anywhere from one-half to five tons of cooling and requires approximately two to four pounds of refrigerant per ton of cooling. At approximately five to 10 minutes to fill one pound of refrigerant, a home that requires three tons of cooling will take about six to 12 pounds of refrigerant and approximately 30 minutes to two hours to completely recharge the unit.

If your whole house is cold that’s one thing, but what if you only have a few rooms that are cold? First, you need to determine why this may be happening. A good place to start is to investigate the potential causes listed in this article—heat transfer, airflow, thermostat problems, humidity, and insulation. Once you’ve narrowed down the issue, you’d apply the same principles to the cold rooms as you would to the entire home.
