| HOMEOWNER CRIES FOR HELP... |
| posted: September 8th, 2008 - 2:04pm |
QUESTION:
While a tech was checking out my system with his gauges, he told me my brand new compressor was bad. When I asked him to explain he told me that it would not pump down into a vacuum. It pumped down to about 5 psi but he insisted all compressors should pump down to at least -20psi. Is this correct?

ANSWER:
You do have a valve in your compressor that is not seating properly but unless you are having trouble, (unit not cooling or running all the time) there is no emergency did he take a temperature drop across the unit. If so you should be dropping the temperature from your return (incoming) air to your supply at least 16 degrees if not you have a problem.
