Common Air Conditioning Questions and Answers
Q. How can I troubleshoot my AC unit before scheduling a service call?
A. If your air conditioner stops cooling, you may be able to check for a few simple issues before calling a technician:
- Set the thermostat below the existing room temperature. You should also make sure it’s set to “cool.”
- Check for tripped breakers and blown fuses, which you can reset or replace as needed. If these problems occur frequently, a professional can help you address the situation safely.
- Ensure all power switches on indoor and outdoor units are on. You’ll also need to make sure the AC disconnect hasn’t been tripped.
If your AC isn’t cooling after these troubleshooting steps, call (717) 397-2577 or request an appointment online.
Q. How can I cool my space more evenly?
A. Adjust the registers on the wall or floor in the room where too much cool air is present so that the registers are partially closed. For example, to get more heat upstairs during the winter, partially or fully close the registers downstairs to force more airflow to the registers upstairs.
Another possible solution is a furnace equipped with a variable-speed blower motor. These furnaces are designed to overcome airflow problems in a home, thus keeping the airflow steady throughout the entire house. These types of furnaces can also save considerable amounts of money in operating costs.
Q. Should I cover my outdoor air conditioning unit during the winter?
A. You should at least cover the top of the condensing unit so no debris can get in (people usually do this with a piece of plywood and something to hold it down). This will also help to protect against damage from falling ice and rodents from entering your unit. Any cover, however, must be removed before the start of operations the following Spring.
Q. Can I turn off my central AC during the winter?
A. You can use the unit’s disconnect to turn the system’s power off and save energy. When you want to use your central air conditioning system again, turn it on at least 24 hours before use to let the oil warm and ensure essential parts receive necessary lubrication.
Q. How does an air conditioner cool the air?
A. As your AC runs, air moves across the indoor coil, which the outdoor unit pumps refrigerant into. The cold coil condenses the air’s heat and moisture onto its surface. Your system then sends the cool, dehumidified air inside.
Q. Are there ways to cool a house that does not have air conditioning?
A. The best way to keep your home at a comfortable temperature is with a reliable air conditioning system. However, we understand that some older homes may not have an AC system installed. Fortunately, there are other ways to cool off your home, such as window treatments, fans, dehumidifiers, and more!
