Your air conditioner should be able to turn down your thermostat and provide cold, fresh air as soon as you press a button. Your AC unit, like other mechanical systems relies on a series interactions between parts in order to produce cool air.

The air conditioner will not work if one of these components fails to perform its task. These are the most common reasons your air conditioner won’t cool your home.

The Thermostat is Set Incorrectly

To make your thermostat work properly, ensure that you have the right setting. The thermostat should be set to “cool”, “auto” or “on” so that it circulates cool air when needed. “On” will keep the conditioner running all the time, even when no cool air is being produced.

A dirty air filter is a problem

Your air conditioner’s filter traps irritating and harmful contaminants such as pollen, dust and mold spores. Air filters can get clogged over time, so it is important to clean them regularly. Clogged filters can also trap cool air inside units, which can cause the evaporator coil to freeze, which can restrict air flow.

A Refrigerant Leak Is Possible

Your air conditioner’s interior is the air handler. It houses the evaporator coil, which is responsible for cooling your home. The evaporator coil absorbs warm air from the inside and turns it into a gaseous form. This heat absorption results in cool, dry air which is then pushed through the house’s air ducts and blower.

The compressor keeps the process going by putting the gas refrigerant under high pressure. It releases heat from the outside, and transforms the gaseous refrigerant into cool liquid using the condenser. The evaporator coil then can create more cool air by starting it over again.

The Evaporator Coil is Dirty and Freezes

The refrigerant used to cool your home is contained in the evaporator coil. The coil heats up inside your home and pushes cool air to the blower. This transforms the refrigerant into a gaseous form. The evaporator coil can become too dirty and may not absorb as much heat. This can cause the cold evaporator’s temperature to drop, which can lead to the cooling process being disrupted.

Refrigerant leaks can cause a frozen evaporator coil to freeze. Refrigerant levels can drop and cause a temperature drop that can lead to the coil freezing.

The Air Conditioner Compressor isn’t working properly

The compressor moves refrigerant from an outdoor unit to an indoor unit. The liquid refrigerant is pumped into your home through the compressor. It then enters the evaporator, where it absorbs heat from your home and creates the airflow you feel in your vents.

After the refrigerant has vaporized completely, all heat absorbed is returned to the compressor. The condenser transfers the heat outside, and the refrigerant is made liquid again.

The compressor can fail, and the refrigerant won’t cool down. Warm air will be pumped into your home.

How to maintain your air conditioner

There are several tasks that you can do on your own when it comes to AC maintenance and repair. Before you attempt DIY AC maintenance, make sure your unit is fully powered off. This can be done via the exterior shutoff box or the breaker box in your home.

Clean your outdoor unit

The compressor and condenser are located in the central air conditioner unit outside your home. Remove any debris or obstructions from the unit by turning it off and taking out the cover. To avoid injury from sharp objects or parts, we recommend that you use gloves when working inside your unit. You can clean the fan inside with a damp cloth, and then spray the fins with a gardenhose.

Clean the evaporator coil

Regular cleaning of the evaporator coil is necessary using a soft brush and a coil cleaner. This will maintain the efficiency of your evaporator coil and ensure that it runs smoothly.

First, make sure your unit is off completely before cleaning the evaporator coil. Locate the air handler of your unit, which is usually located in a closet, attic, or garage. Spray no-rinse cleaner directly on the evaporator coil by removing the access panel. To gently remove any debris, use a paint brush or nylon to brush it off before you replace the access panel.

Replace the blower filter

Cool air won’t reach your house if the filter is blocked. Cool, clean air should be maintained throughout your home by changing your blower filter at minimum twice per year.
