If your water heater is in a heated space, then a condensing water heater can save a ton on electricity.

That was just a clogged condensation drain line.  

Do you have a hot water heater or A/C condenser in the attic?

so I'll do my best to condense the situation down.Last September I got soft hearted and agreed to a renter who had been down on his luck  (ya I know don't think with the heart) and that the rent was  going to be paid by the Idaho Housing Authority.  

It's then just a matter of adding the A coil and running the lineset to your condenser.

Paint, I saw some PVC running from the heater which I thought it should be copper but I believe it was for condensation..

AND many times they will not let you condense the QuickBooks file.For pennies a day (for three years) it is worth any software ONLY if you are looking to grow in your business. 

If you have a maintenance guy, just have him go to each ac and clean the outdoor condenser and change the filter every May.

Keeping the outside condenser unit clean is also something I prefer to do especially when the coils get coated with dust, cotton wood & sooty mold from old trees. 

Lasts 3 months but the coil gets wet and cleans itself via condensation over the 3 months so that may be all you need unless heater season.
