my meter dropped from my hand and right into a emergency pan filled will water. this thing is just 30 days old and now is drying out.
The good news is I was able to sell a major duct renavation at this house along with a A/H.So to be able to pay back another testo 510 ,if i get no response in the morning. this 5 ton system has a brand new lennox condenser only.
the compressor valves are leaking at start up creating loud noises.
the airhandler is 20 years old with 2 10" uninsulated flex runs as the only returns.
Oh yea the clogged drain is what caused the emergency to fill up.
tomorrows another day...........................
