Once the temperature hits 55+ degrees and stays above that for most of the day, you can get a maintenance check done on your air conditioning unit.
Things you should know about your A/C checkup:
- It’s going to be cleaned. There is a condenser coil on the outside of the air conditioner. You’re A/C unit draws in air to cool off the compressor as it’s running the refrigerant through your house. The condenser can pull debris, dirt, grass and leaves into it while running. These things can get caught in the outside condensing coil, which is why a good cleaning is an important first step.
- Your refrigerant levels are checked and technicians give the unit a once over to make sure there are no critters inside. Mice can sometimes get in there and chew wires. It’s also not completely unusual to find a snake once in awhile. The coils, wires and controls are cleaned out. Levels are topped off if needed.
- A new air conditioning system comes from the factory pre-charged but depending on the length of the line set you may have to add some refrigerant to it. If you have a company that does a normal install with a 100 foot set line and doesn’t add adequate refrigerant, the levels will be low and so will the charge which could cause problems.
When refrigerant is low it can cause the life expectancy of your equipment to fail or cut that time in half. Plus, your unit will not work efficiently.
Common problems technicians come across
- The coils on the outside of an A/C unit are delicate and people sometimes take a pressure washer to it to clean it and end up bending those coils over, causing a restriction. This can happen even with a high-pressure garden hose.
- Forgetting to disconnect power so while you are cleaning the unit, the outdoor fan kicks on and your hose or worse, your fingers are inside the air conditioner.
- Low refrigerant levels can damage your inside coils, cause leakage from freeze ups or leak water onto your furnace inside
A preventative maintenance check on your air conditioning unit takes between half an hour to an hour depending on whether there’s a heat pump or a control board.
