Tips for Inspecting Your AC Unit Before Spring

Articles

If you are looking forward to the end of winter, then you may already be looking at your air conditioner and thinking about what needs to be done to get the appliance up and running. This should be a concern of yours if the unit has been subjected to snow, ice, wind, and rain for the last several months. If you want a jumpstart on the warm season, then keep reading to learn about a few things you should do.

Inspect the Control Box

Central air conditioning systems are electronic appliances that require you to plug in the device for power. The power service is wired to an outdoor control box or panel, and this unit contains the electrical plug as well as the circuit breaker for the condenser unit. While most control boxes and electrical panels have a cover that screws into place, the screw and the cover can come loose. If this happens, the electrical components can become wet. This can cause a short and a dangerous electrical situation.

Typically, the circuit breaker will trip if you try to turn on the AC unit when the outlet or the wiring is wet. You can test the unit to see if this happens. If the unit start up fine and runs, then replace the cover. If the breaker trips, then flip the switch on the outside of the control box. This is the compressor service switch. It cuts off the electricity to the air conditioner so a technician can safely assess the appliance. 

Your air conditioner will typically have a separate control panel or control board on the compressor itself. This part of the system contains the electrical wiring, sensors, safety shutoffs, and contractor relay for the unit. It also contains the electrical wiring for he exhaust fan. You can and should check this part of the system as well, especially if a portion of the AC casing has been damaged in any way.

Inspect the Tubing & the Fins

Snow and ice can place a great deal of stress on an outdoor air conditioning unit. This means you can and should inspect the exposed parts of the unit carefully. One part of the system that is likely to become damaged is the insulation on the pipe that feeds the coolant back into the compressor. While the insulation does stop the pipe from becoming damaged from ice and snow, it also helps to keep the coolant at a consistent temperature. This allows the coolant to release heat as it moves through the coil of the system. If it releases heat too soon, then this can disrupt the pressure of the coolant and keep your unit from working correctly.

If you notice insulation that is damaged, then replace it immediately. A replacement should also be made if the pipe itself is damaged. When you complete this inspection, make sure to take a look at the fins that line the outside of the unit. They can bend over time as they are exposed to adverse weather conditions. Bent fins can sometimes be bent back into place, but do so carefully. Some fins make break off due to weather exposure and also due to the corrosion of the aluminum. If too many fins break off, then the entire coil of the system may need to be replaced.

When you inspect the fins and bend them back into position, use a rag to clean them gently too. You can use a hose to clean the fins if debris does not release. If you notice corrosion and bending, then make sure to invest in an air conditioner cover next year.

New Trends In The Construction Industry

My name is Brandon McCauley and this blog is about new trends in the construction industry. In this blog you'll learn about new types of materials that are long-lasting and durable. You'll also find out how new homes and businesses are being built to be more energy efficient. I continually study new trends and the latest developments in construction because this is an interest of mine. I'm always amazed when I see new building and home designs that are out of the ordinary. If you also like learning about new construction trends, I think you'll find my blog very interesting and informative.
