Performing AC diagnostic service on 2011 Goodman condenser, system runs but is not able to cool the home at this time. Looks like previous owner replaced condenser and left 1988 furnace and coil. Hooked up refrigerant gauges and discovered that system has major leak, all refrigerant has leaked out (R22). Clients decided to move forward with system replacement and we will be installing a brand new system very soon, we look forward to keeping clients comfortable for many years to come!

AC tune up! Getting their ac up to par before the summer heat wave hits. Having an older system means a regular maintenance is more important!
