The condenser unit is a huge part of a central air system. Since this unit is located outside, where it is exposed to the elements, certain parts of it are prone to get damaged or worn out over the years. The hoses that connect the condenser to your home are especially vulnerable. This article explains how to check and fix these hoses.
The Electric Cord
The electric cord that leads from the back of your unit and into the wall of your home is not technically a hose. However, it is wrapped in a rubber tubing, so it look like a hose. It is much wider than a traditional power cord. Most homes will have a small electric box mounted to the wall directly next to the unit. The key is to check the cord, and make sure that the connection into the box is tight. If you have been having electrical issues, this cord could be the source of your problem. Also, make sure the rubber tubing is not punctured. Any holes in the rubber can be dangerous because it can mean that you wires are no longer waterproof. If this is the case, you should immediately shut the power off to your unit and call an HVAC professional.
The Air Hose
The air hose that leads out the back of your unit and into your walls is usually smaller than the wall fitting. There will usually be a transition piece that connects these two. Make sure this piece is air tight and secure. You can always reinforce both ends with duct tape. You can do the same with the fitting where the hose connects to the back of the condenser. You should run your AC and check for air leaks while it is running.
There is a small risk that your hose can get punctured or even chewed through by rodents. If there are any holes in this hose, you should just replace it completely. Hoses are cheap and easy to replace. You can even take the old hose to the store with you to make sure you get a replacement that is the right length and gauge. You should also replace the hose clamps when changing the hose.
These two connections are vital to the functionality and airflow of your central air. You don't need to be an expert to figure out how to easily repair the air hose and keep your unit working well.
