To safeguard against the coming heat is a fully functioning air-conditioning system. There are a few steps you will want to check before moving that switch on your thermostat from heat to cold.
It is helpful to understand how your whole system works. A central air system has three main sections: condenser, blower and your home’s ductwork.
Behind your home or garage and sometimes hidden is that large box-like metal unit. This is the condenser. It’s designed to regulate the thermal reading of the refrigerant, which is usually Freon. This refrigerant goes back and forth from the outside unit to the house. The condenser pressurizes the Freon gas as it comes from the house and transforms it into a high-temperature liquid. In this new state it rushes back to house where the blower unit takes over
As the transformed gas enters the blower unit, it’s changed back into a gas and becomes much colder. This climatically-changed gas is then pushed through a coil located in your ductwork. As air blows over the coil, it cools before it re-enters the house. The air drawn by your blower ductwork comes through return air vents in your home. As Freon finishes its work, it migrates back to the condenser where this cycle is repeated
Leave the more sensitive parts of your system like refrigerant conduits to the heating and air professionals. However, there are some easy things you can do to keep your system healthy while waiting for summer to arrive
Check Your Filters
Located right at the blower unit and commonly situated where the return duct meets the condenser unit, should be your filter. Since airflow is an essential part of your air conditioning system, keeping a clean filter for highest level of airflow is essential. If your filter becomes clogged it is difficult for enough air to pass over the system and it is not uncommon in these situations for ice to build up on the coil and cause your unit to seize up.
Inspect for Any Water Damage
As warm air passes over the cooling coil, condensation occurs. Beads of moisture develop. In an air conditioning system this moisture can be streamed to a gravity-fed drain or a pan located beneath the unit. Some of these pans have a pump system which pushes the water through a pipe and into a drain when the water in the pan reaches a certain level.
Test to insure they are working or you might suffer some water damage. If there is any water damage to your A/C unit contact a professional for advice.
Keep Your Outdoor Unit Clear of Obstruction
If the outside condenser is going to work correctly, there needs to be enough space around the unit for proper airflow. Give it at least two feet of unobstructed space.
Plant growth or other debris can clog your unit and cause it to run less effectively.
Maintain Your Ductwork
• Make sure there are no obstructions in or around the air vents in the home.
• Check for mold. Due to condensation air ducts can accumulate moisture. This in turn, can create mold. This is a great time to consider a precision clean and tune. Clean ductwork will keep your system running efficiently.
• Adjust ductwork dampers to redirect the air to the second floor. On a side note zoning systems reduce the need to adjust ductwork dampers
