"Ted from Ridgeline was an absolute professional! His communication skills made us feel comfortable and his workmanship was unmatched retrofitting a house that was built in 1950 that never had AC and being a master electrician fixed other issues that came up. Ridgeline was fair and honest, certainly a reputation that will keep us calling Ridgeline in the future!"

"We had a botched contractor disconnect our gas line from our garage to our house for an addition, but threw away the connectors and leave before the project was done. I added my project to Angi and Jordan from Conradt Quality Air reached out to me and was able to complete the project! Jordan was great to work with, he was punctual, responsive, respectable and a great price with quality work to show for it! We will definitely be reaching out to Jordan with more projects in the future!"

Heating and Air Conditioning questions, answered by experts

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.

Modern AC leak sealants work as a temporary measure to stop refrigerant leaks. You can purchase them at most home improvement stores or on online. When using an AC leak sealant, keep in mind that it’s only a temporary solution, so you’ll still need to hire a pro to install a replacement part as soon as possible.

You can protect your air conditioner in the winter by turning off the power at the thermostat and performing routine HVAC maintenance in the spring. Regular maintenance, cleaning, and repair of your AC unit helps protect it and extend its life span. If you have a window AC unit, remove it from the window and store it in a dry place during the winter. Window units cannot withstand freezing temperatures. Keeping them in your window also allows cold air to seep into your home.

While your AC unit may still run even if its capacitor is going bad, doing so takes a lot more energy, so it can drive up your electric bill and cause further damage to your AC unit’s parts. If you suspect a bad capacitor, it’s important to have a professional diagnose and fix the problem before you continue to run your AC.

You should only run your dehumidifier in warmer months, such as spring and summer, to get the best performance out of your system. The air gets drier when temperatures drop in the winter months, creating less of a need for a dehumidifier. However, when to run a dehumidifier will depend on your local climate.
