● Walk outside and take a look at your air conditioning system’s outside unit. This is called the condenser. If you covered the condenser over the winter, make sure to remove the cover before you turn it on.
● Remove any objects or vegetation within 18 inches of the unit. It’s not a bad idea to take a hose and spray off the coils. Use a hose with a nozzle and spray the coils at a 45-degree angle to remove debris between the fins.
● Back inside the house, check the filter for the air conditioning unit. Homeowners often overlook the inside part of the central air system, and this is where many problems begin.
Changing the filter regularly is the best thing you can do for your central air system. Change it once a month in the summer and use a pleated filter.
Before you turn on your central air system for the first time, make sure you have a new filter in place and that there are no gaps where the air can pass unfiltered.
● Now that you have inspected everything, it’s time to make sure the breaker and/or disconnect switch to the condenser is turned on. After this is done you might want to close all the basement vents. You will want the air from your system to be concentrated on your middle and upper floors, where it is needed the most.
