My wife and I had a heatpump installed last winter. Our utility bills
immediately went up. Since the summer began we are now paying three times
what we did before for electricity. The person who installed it says
nothing is wrong with it and he can't understand our utility bills - he says
they're due to something besides the heat pump. It seems to run all the
time and never really gets the temperature down as much as we would like.
Also, there is a LOT of condensation on the inside at the blower. Can
anybody offer any suggestions?
Thank you

Could be over- or under-charged.
Could be a dirty air filter.
Could be your dog scratching fleas by the return air grill has plastered
the evaporator coil with dog hair.
Could be too many supply vents closed.
Could be inadequate ductwork.
Could be blower speed incorrectly set.
Could be it's hotter there this summer.
Could be an equipment mismatch.
Could be an equipment sizing error.
Could be heating elements energized.
Could be a dirty condenser coil.
Could be that the utility rates went up.
Could be a combination of the above.

Of these, the first to check would be the air filter, then the
refrigerant charge.
Many third rate techs don't know how to charge a system properly, which
always ****es me off, since this is the most basic hvac issue, and it
isn't very hard to learn. cowboy would be one of those who you wouldn't
want to have check the charge.

Call another company out and post back their words of wisdom for us.
