3 Factors to Consider When Replacing Your AC

Age:
Unlike fine wine, AC systems do not get better with age. A current, high-efficiency AC system uses between 20 and 40% less energy to generate the same level of cooling as a system that is 10 years old. If your system was installed prior to January 1, 2015, it’s likely to not meet the new standards for central air conditioners.

If you aren’t ready to replace your whole system just yet, you may want to consider replacing the condenser and coil with something more efficient. One of Goettl’s expert technicians can help determine if this is the best way to upgrade your efficiency without replacing the entire unit.

SEER Rating:
SEER (Seasonal Energy Efficiency Ratio) is a number which indicates how much cooling power your HVAC system can produce for every unit of energy it uses. The higher the AC unit’s SEER rating, the better. Today’s HVAC systems are designed to function at a minimum SEER of 13. This reflects a 30% increase in efficiency over past efficiency requirements (10 SEER). Very old HVAC systems could even have a SEER as low as 6.

Keep in mind that the SEER rating reflects when the unit was new. As systems get older, efficiency goes down. So, after 10 years, even a 13 SEER unit may not remain at that level.

R-22:
If your AC unit operates on an R-22 refrigerant (freon), it’s approaching its life expectancy. This ozone-depleting refrigerant is harmful to the environment and will no longer be manufactured as of January 1, 2020. R-22 has been replaced with R-410-A refrigerant. So, if your AC unit already uses R-410-A, it’s still relatively new.

As we mentioned in our Phasing Out R-22 blogpost, consider scheduling a service appointment to have Goettl’s top off your AC unit with R-22 prior to the end of 2019.
