Air Conditioning Tune Up
1. check for refrigerant gas leaks
2. check all operating pressures
3. clean and check indoor coil (if accessible)
4. clean outdoor coil
5. up to 1lb of refrigerant
6. clean and check condensate drain
7. check starting contactor
8. check compressor and fan motor for proper voltage and amperage
Spring is a generally mild season. It's also the ideal time to budget a bit of that savings for an air conditioning tune-up. Done now, it can prevent many small problems from becoming big, expensive problems later.
Q: How often should I recharge my air conditioner with new freon?
A: Contrary to popular belief, air conditioners do not consume refrigerant (freon) as a car consumes oil, so under ideal conditions it would never need changing or filling. Therefore, a low freon level indicates a leak which should be repaired before adding more. While most new system connections are welded to minimize leaks, many older units (8+ years) were connected with mechanical flared fittings which can vibrate loose over the years, causing leaks.
