"Clark Heating and Cooling was able to come to my house the same day that I called for a much lower service fee ($74) than other companies that I called. The Clark technician immediately knew what was wrong with my AC when he heard the unit and had the part replaced in under 20 minutes."

"This was my first time using Cardinal Heating & Air Conditioning, and it was a fantastic experience. I received a phone call asking me if I wanted to schedule my annual air conditioning check, and when I said yes, the scheduler informed me that she could have a technician come out that day. The technician arrived within a couple of hours and did a thorough check. Everything checked out, and I am ready for the hot summer months."

"We hired Hopper to replace a a 19 yo central AC system. They suggested a solution that saved was 14.3% less than ordering new system from the manufacter. And more importantly they had it installed 2 days later. Hooper is a well establised company that has earned its good reputation."

Air Conditioning questions, answered by experts

If your AC unit isn’t cooling and you haven’t figured out why, there are a few good reasons to turn it off ASAP. The source of the issue, whether that be leaking refrigerant or a broken compressor, will worsen and cause more damage to the overall unit the longer the machine is allowed to run. When in doubt, shut it down until you or an AC pro can ensure everything is working properly.

A one-stage air conditioner only has one setting, while a two-stage air conditioner has a high and low setting. A two-stage air conditioner costs between $500 and $2,500 more than a traditional air conditioner, but it has a longer lifespan and helps to increase energy efficiency. To make this decision, you should consider your energy needs and available budget.

While it is possible to add Freon to your AC unit yourself, it is not recommended. In fact, the U.S. Environmental Protection Agency (EPA) prohibits the handling of Freon without a license. Freon is a dangerous gas that can cause irreversible damage to your AC or yourself if not installed correctly. It is worthwhile to hire a professional to add Freon to your AC.

No, it’s not normal for AC vents to drip condensation. A sweating AC vent is a sign of something wrong and can lead to issues like air duct rust or mold growth. Your HVAC unit might not be working efficiently because of a dirty filter or clogged ducts. Alternatively, your ductwork might not have adequate insulation, which allows the cool air in the ducts to meet the humid air outside, causing condensation. 

AC evaporator coils should be cleaned at least once per year to keep your unit in good condition. For optimal performance, consider cleaning them twice a year—once before and once after the main cooling season. More frequent cleanings may be necessary for older systems, units with performance issues, or those in climates with high levels of humidity, dust, and dirt.
