AC Troubleshooting in Glendale, AZ

You purchased an air conditioning system for your home so that you and your family can stay nice and cool in the hot summer season. It can be extremely frustrating when you know that your air conditioning system is on, but it’s not producing cold air. By taking a few seconds to understand the information below, you can help to identify the culprit of your issue and get it fixed quickly.

Wrong Temperature Setting

Typically, it’s very easy to overlook a simple temperature setting as being the culprit of your air conditioner not producing enough cold air. It only takes a couple of seconds to check out your thermostat to ensure that the temperature settings are correct. Your thermostat should be on the cooling function, and the temperature setting should be below what the indoor temperature reading is.

Blocked Condenser Unit

One essential component of your air conditioning system is the outdoor condenser unit. This unit has a number of openings on it to allow fresh air from the outside to pass through the unit. Whenever these openings get blocked, it can drastically hinder the performance of your air conditioning system. This is due to the fact that the outside air is unable to make it through your unit and disperse the heat that is inside of it.

To fix this issue, you’ll need to remove any loose debris or greenery that is surrounding your condenser unit. You need to leave a good two to three feet of space around the entire outdoor condenser unit in order for it to get enough free airflow. Whenever you clean up around the unit, it’s also a good idea to clean the inside of the unit out as there’s likely loose debris inside of it as well.

Clogged Air Filter

It’s not uncommon to fall victim to having a clogged air filter that blocks your air conditioning system from producing cold air. Most experts throw out a recommended changing frequency of three months. In the summertime, your air conditioning system is working longer hours. This will typically cause your air filter to remove more unwanted airborne debris from the air. When too much debris gets stuck in the filter, it clogs up.

When a filter is clogged, your air conditioning system has to work harder to try to push air through that clogged filter. This drastically reduces the airflow for the inside of your air conditioning unit and can greatly hinder its performance. You should be pulling out your air filter and holding it up to the light to see if you can clearly see through the filter. If you can’t see through the filter, it’s time to change it out.

Low Refrigerant Level

Refrigerant is a very important component of your overall air conditioning system. It works to transfer the heat from the inside of your home to the outdoor condenser unit, where it can be dispersed into the air. When you do not have enough refrigerant inside of your air conditioning system, it can be impossible to remove a large amount of heat from inside of your home.

Refrigerant leaks can come on quickly or slowly over time. Quick leaks tend to create a distinctive hissing sound where the refrigerant rapidly flows out of the leak. When it comes on slowly, there are usually a bunch of pinhole leaks that develop in the copper tubing that houses your refrigerant.

Fixing this issue is a two-part problem. You first need to have the leak or leaks in your copper tubing fixed. Then, you can have a qualified air conditioning specialist recharge the refrigerant inside of your system. Refrigerant can be a dangerous substance, so it’s best to leave it up to the professionals to handle this sort of issue with your air conditioning system.

Ducting Blockage or Leak

Most air conditioning systems utilize a series of large piping that runs in the walls and flooring of a home and is referred to as ducting. Whenever this ducting becomes blocked or develops a leak, it can hinder the circulation of air throughout your entire air conditioning system.

To assess whether you have a ducting problem, you should locate the first supply vent that your air conditioning system goes to. This can be done by locating the ducting that comes out of your air conditioning unit and seeing where the first vent is likely to be placed. Put your hand up against the vent and see if there is cold air coming out of it.

If the vent doesn’t have cold air coming out of it, then it’s likely a different issue. However, if you notice that this first supply vent does have cold air coming out of it, you’ll want to move to the next supply vent on the ducting line. As soon as you notice that there’s no cold air coming out of a supply vent, you’ll know between which vents the ducting issue is located.

In most cases, you won’t have visible access to the vent due to its location within a wall or the floor. By calling in a professional, they can use specialized equipment with a camera to run through your ductwork to identify the source of the problem. It’s not uncommon for insect infestations to block up a section of ducting. In addition, large ducting leaks due to rodent damage can also allow the cool air produced by your system to escape into the wall cavity instead of into the room.

Frozen Coils

Your air conditioning system consists of coils that the refrigerant runs through. The air from inside of your home is blown over the evaporator coils, and the heat from that air is transferred to the refrigerant. The now cold air is redistributed back into your home. The refrigerant is pumped to your outdoor condenser unit, where another fan blows over it to disperse the heat into the outside air.

As the heat is removed from the air inside of your home, so is any excess humidity. The water drops will develop on the condenser coil and eventually drip down into the drain pan. Unfortunately, if there isn’t enough air blowing over the evaporator coils, the refrigerant can become extremely cold. When this happens, the moisture that is on the evaporator coil will actually freeze up in the ice. This is what is referred to as a frozen evaporator coil.

Frozen evaporator coils can be a result of a number of different problems. These include dirty coils, clogged filters, low refrigerant levels, reduced airflow due to rodent infestation, or even clogged drainpipes. Due to the complexity of this type of issue, it’s usually best to hire an air conditioning expert. Let them identify the cause of the frozen evaporator coil and fix it. You will need to let your system thaw out for a few hours before you can turn it back on again.
