Keeping your home up to snuff for the summer isn’t always easy, and your central AC system is a big part of that. You and your family deserve to stay cool whenever those heat waves decide to come along. So to help you sustain your air conditioning unit, we recommend you schedule AC maintenance sessions with our professionals at Approved Comfort in Lake in the Hills twice a year.

In the meantime, we would like to share with you 3 AC maintenance tips below to keep your home in Lake in the Hills at a comfortable temperature during the summer months.

In case you didn’t know, central air conditioners have two main parts: the condenser and the evap­orator. The condenser is the device located outside your home, usually on top of a cement slab, and the evaporator is normally mounted above the furnace.

1. Clean Your Evaporator Once a Year

Remove the outside foil and tape carefully, then unscrew and ease off the plate. Using a bristled brush, clean the underside of the evaporator. Then clean as far back as you can reach. The evaporator can slide out a bit – just be careful not to bend the pipes. Clean the tray underneath the evaporator. Next, pour one tablespoon of bleach into the hole in the tray so mold doesn’t grow. Return everything to its place, turn on the AC and check for leaks.

2. Maintain the Condenser

Since the condenser can collect debris easily, you must clean the fan that moves across the condenser on the intake side. Make you sure know which side is which by watching it move before you turn the power off.

After you turn the power off, cut away any grass or anything obstructing airflow. Then clean the whole condenser with coil cleaner and let dry. Next, remove the grille and lightly clean the fins with a soft brush. Straighten any bent fins with a fin comb (sold at most hardware stores). Ensure that the concrete slab is level. Make sure to cover the condenser during the winter months as well.

3. Be Careful with the Refrigerant

Most AC systems call for a refrigerant named Freon. Without Freon, no cooling would occur. If you detect there’s a problem with the cooling, a recharging is in order. Do not attempt to recharge the refrigerant lines. Contact our AC maintenance professionals to get this done safely and properly.

You should, however, be able to repair your AC system’s coolant lines. Look at the lines running from the condenser to the evaporator. If their insulation is torn and ragged it will hurt the unit’s cooling efficiency and need to be replaced. Make sure to do this as soon as possible following the insulation’s manufacturer’s instructions.
