Heating and Air Conditioning questions, answered by experts

The cost to add Freon to an AC ranges from $100 to $350. It can increase up to $600 for large AC units requiring much more coolant. The cost also depends on how much refrigerant your unit needs. If only a small amount of Freon leaked out, your cost would be on the lower side. A complete replacement of all the required refrigerant can get expensive.

You should get anywhere from three to five quotes for HVAC replacement to get an idea of the average cost of a new unit. Although this quote-collecting process can be time consuming, it allows you to compare what work is required, what type of unit you should install, and how much you should expect to pay for the service.

Excessive humidity in a room often manifests through visible signs like condensation on windows or walls, a musty or damp odor lingering in the air, peeling wallpaper or paint, and the presence of mold or mildew. Experiencing discomfort due to a consistently clammy or sticky feeling can also indicate high humidity levels.

There are many recognizable symptoms of AC compressor failure. They include loud banging noises, hot air being continually circulated in your home despite running the AC at full blast, uneven airflow and cooling, and electrical issues like constant surges due to the compressor working overtime. While some of these symptoms, like uneven cooling, can have other root causes, they are common indicators of compressor problems.

They can, but it’s not as common. Window AC units are much smaller than whole-house systems and less likely to develop refrigerant leaks or similar issues. As a result, you will rarely need to add a new refrigerant, limiting overcharging problems. However, it’s still important to leave refrigerant management in the hands of professionals when window units need work.
