I concur, Doctor. The system should be cleaned. The tech should shut
off the power, pour on purple liquid, wait, rinse, repeat. Should ask
to use your garden hose. Ask him (her?) to spray the side of the house
occasionally. That cleaning stuff can damage house siding.

Could also be low on freon. (Bad thermostat joke to follow, sure
enough.)


I went to the home of one of my commercial customers Saturday to
install a wireless N router for his computers. Sunday morning he calls
me about one of his AC units not cooling. I walked up to the condenser
and heard a humming sound and sure enough, the combo capacitor was
bad. The top was popped up on that damnable Chinese capacitor. It was
a 440 volt cap too. He lives out in a semi-rural area and I'm going
to recommend surge arresters for the heat pumps.
