When it starts getting cold outside, do not simply turn the thermostat up. Instead, there are things you should do to the air conditioning (AC) unit to ensure it works properly when you turn the thermostat back to cool. This is especially true if you were having any kind of problems with the AC unit at the end of the summer. To help you, below are two problems you may be having, as well as tips on getting your system maintained once the problems are repaired.

Fluctuating Temperatures

If you noticed the temperature fluctuated inside your home during the summer, this is likely due to a refrigerant leak. In this situation, you should contact an AC repair company like GNL Heating and Cooling. They will send out an AC repair technician, who may find that the leak is located in the evaporator coil, condenser coil, or the refrigerant line sets. They will determine the area and repair the leak. They will then add refrigerant to the unit until it is at the right level.

Water Around the Exterior AC Unit

If you notice there is water leaking around the exterior AC unit, the drain line is likely the problem. The drain line for your AC unit can get clogged with dust, dirt, and other debris. You can look at the drain line by removing the panel from the AC unit.

You will see a drain pain inside the air handler. A condensate drain line comes from the drain pan. Look at this line with a flashlight to see if you see any clogs. If so, you should hire a professional to clear the clogs. If you do not do this, the water outside the unit could get inside the AC unit causing damage.

AC System Maintenance

When the HVAC contractor finishes repairing your system, they can provide maintenance to it. This will also help the unit run well during the winter months.

The HVAC contractor will go outside to look at the unit. They will first remove the cabinet and inspect the condenser coil. This coil may be dirty and if so, the contractor will clean it. The contractor will check for loose wiring connections and tighten any that are loose. The relays and contactors will be inspected and cleaned, if needed.

The contractor will look at the fan blade to ensure all blades are straight. If they are not, this can restrict airflow, causing your AC unit to work harder to keep the set temperature setting. The contractor can use a special comb to straighten the blades.

If there is any debris inside the unit, such as leaves or grass, it can be removed by using a vacuum hose.

Talk with an HVAC contractor about this information and they can give you many more details.
