Have HVAC Questions? Ask an HVAC Expert for Answers
Hi, I'm Tim and I'm an HVAC expert here to assist you with your questions. Please provide all information I request as it makes it more difficult to troubleshoot something when I'm not there onsite. Essentially, you become my eyes and ears. Thanks for the opportunity to help. At the end of our dialog, you will have a chance to rate my service, but please wait until we are finished and you're satisfied you have all the information you need.
You may need to get a new HVAC guy. There are many possible reasons for this. The fact that when you hose it down, it runs, tells me it is probably running high head pressure and the compressor may be going off on internal overload. This can be caused by an overcharge, or air and non-condensables in the system. This happens when it is not properly evacuated before putting into operation.
