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. Please be patient as many times we work with several customers at once.

Are the condenser coils clean?

Those on inside?

Nope on outside unit.

Customer: replied 1 year ago.
Can we do this by phone
Customer: replied 1 year ago.
All looks clean on outside unit
Expert:  Tim H. replied 1 year ago.

Take a hose with a sprayer attachment, and starting from the top, rinse through the coils all the way down. Thoroughly clean them out. Let me know when this is done, please.

Customer: replied 1 year ago.
Actually it just started up. I reset the fuses
Customer: replied 1 year ago.
How about that
Expert:  Tim H. replied 1 year ago.

It will probably go out again if condenser coils are dirty or condenser fan is not running

Expert:  Tim H. replied 1 year ago.

Its had time to cool down.

Customer: replied 1 year ago.
Like I said everything looks clean
Customer: replied 1 year ago.
Far as I can tell
Customer: replied 1 year ago.
I'll clean them off anyway
Expert:  Tim H. replied 1 year ago.

Can't go by looks. There can be dirt trapped between the coils

Customer: replied 1 year ago.
Good to know
Customer: replied 1 year ago.
You say a hose will do it?
Expert:  Tim H. replied 1 year ago.

Hose with a sprayer attachment. Set to steady stream.

Customer: replied 1 year ago.
Ok - thanks Tim
Expert:  Tim H. replied 1 year ago.

While out there, make sure the condenser fan is running and blowing air out the top.

Let me know if you have additional questions. Otherwise, good luck! Thanks for using Just Answer and please don't forget to rate my service as that's how experts get paid (thanks in advance for any bonus left). Otherwise experts work at their own time and expense. Even though the Just Answer site has your money on deposit, it does not get transferred to me until you (positively) rate my service. Feel free to post back with any more questions. Remember, you can rate question at any point and still ask more questions (related to the same thing) later on. Experts prefer if you rate question at the end of our first chat.
