"A giant shoutout to Atlanta Air Authority for coming to our rescue this week. We came home from being out of town on Sunday to a hot house. Our A/C unit was toast. Their quick response and fantastic service had us back up and running with a new unit within 3 days. Canâ t say enough good things about them. Definitely check them out next time you need HVAC service!!"

"I wanted to say a few things about this company. My other company sold to Dayco and this is my experience with the HVAC department. I called them because my upstairs unit was making a strange noise. Dakota came out and found the problem. He recommended what was needed and gave me an estimate. He was very professional. Later I spoke with Lane the service manager to ask a few questions. He was extremely helpful and also very professional. So, I will say that my first experience with Dayco was a very positive one. I would recommend anyone to give them a call."

Heating and Air Conditioning FAQs, answered by experts

Here’s the cost formula to find out how much it’ll cost you to run a window air conditioner in your home:  Watts * (hours used) / 1,000 * (Local kWh) = daily cost of running a window unit. If you need help calculating the cost of running your window AC unit, consult an AC repair or installation pro for an accurate estimate.

When a compressor gets overheated in central air systems or heat pumps, it can still cool your home for a while until it eventually gives out. If the compressor is chronically overheated and no one addresses the root cause, it will create an incredibly expensive problem when your entire HVAC system breaks down and stops working altogether.

Mold in your air conditioner isn't a good thing, as it can be harmful to your health. If the mold travels through the ductwork or is blown out of the A/C, you and your family can inhale mold spores and develop respiratory illnesses and other problems. Preventing mold from growing in the air conditioner will help protect your health.

One of the first signs of mold in an air conditioner is a musty smell. You're likely to notice the smell when the unit runs, from the air coming out of the vents or the unit itself. You may also be able to see mold growing on the unit, such as near the condenser coils or by the fan. In some cases, there may be visible mold by the vents.

You should use a breathable, weather-resistant cover with ventilation. It can be a top cover or a full cover that has mesh to allow airflow. A full, non-breathable cover can cause moisture to build up, leading to rust, frozen parts, and corrosion. A full cover also attracts unwanted critters, such as mice, that can damage the wiring and your unit. If you need to protect your AC unit from falling icicles, choose a sturdy top cover or piece of wood that prevents icicles from damaging your unit.
