Most people do not give air conditioning (A/C) a second thought as long as we get cold air. However, the A/C is a complex and expensive system, which we should think about before we lose the cold air.
The refrigerant in the air conditioner contains a special oil to lubricate and cool the A/C parts. When enough refrigerant leaks out, your air conditioner may still blow cold air, but the parts lose the protective oil and wear out faster, so air conditioner maintenance is important.
Replacing old refrigerant has another benefit as refrigerant tends to gather moisture and become corrosive. The corrosion cause leaks, which can be expensive to repair. Fresh refrigerant protects the air conditioning components and keep the system operating at peak efficiency, so the system does not have to work as hard to keep you cool.
A/C parts can wear out even with regular service. Normal wear-and-tear eventually gets to all moving parts. Addressing early problems can save on more extensive repairs. For example, a common failure is the clutch that turns the compressor on-and-off. If you can take care of a bad A/C clutch when problems start, you may save the compressor. Wait too long and you may have to replace both.
Check your owner's manual or ask us for service recommendations. Last, if you hear strange sounds when you turn on the air conditioner or the air does not blow out as cold as before, have us check everything out to see how we can keep you cool.
