If the outside unit rated 10 SEER needs to be replaced once there are no remaining 10 SEER parts, it will be necessary to upgrade to a 13 SEER unit. This may require a modification to the inside unit to ensure proper compatibility between the inside unit and outside unit.
How contractors go about making the two units compatible can vary, depending primarily on the age of a system. In certain circumstances, a valve called a thermal expansion valve (metering device) can help the two units “talk to each other,” and in other instances, the system will not work to peak efficiency unless the homeowner replaces the inside equipment. The cost for these internal fixes can range from several hundred to several thousand dollars.
To help our current customers through the transition; JACS is offering new equipment at 15% to 25% off last years mark ups.
