.- There is no such thing as the "Congressional Reform Act of 2012" (previously referred to as the act of 2009, 2010, and 2011 -- it keeps getting updated each year in the email circulation).

That would get the air circulating and dry out any moisture.

Then encourage my future tenants to run the house circulating fan 12 hours a day.

Gas flue isn't sloped correctly for combustion air to exhaust properly Remove debris from ductwork (brick/ mirror chucks, etc. seen when vents were removed) which prevented air from circulating.

With wall units on first floor it is best to find a way to circulate that heat.

An interesting side point is that there is apparently no issues with credit worthy customers getting funded, contrary to some of the reports being circulated.

You will have to re-pipe, add circulation pumps, run new gas lines, etc.

hi marcus. yes, filters need to be changed often. in fact, i recommend at least once a month, depending on the location of your furnace and cold air return system. that being said, here is my experience and expertise. ( i just competed getting my certification in furnace repair). the purpose of the cold air and fan are to circulate the hot air to the area where heat is needed. but the purpose is also to cool the heat exchanger in the furnace as well. the heat exchanger is a sealed system of pipes that the heat created by the burners heats up. the air from the fan/ cold air return blows passed the heat exchanger to circulate the heat to other areas and to cool the heat exchanger. if the filter is clogged, no air gets past the heat exchanger and consequently, the heat exchanger will overheat and get damaged. i have personally seem the heat exchanger with massive holes in it due entirely to a clogged filter. it is highly unlikely that your heat exchanger inside is full of dirt, but the fan and area around the heat exchanger could be filthy

I just acquired the property in December, fixed it, and leased it in JuneThere have been a lot of items that they complain about like:AC not cold enough upstairs (this was repaired)Sprinkler busted (I believe this is a tenant expense but I fixed anyways)Water Heater not hot enough (I added a re-circulation pump, and didnt mind doing this)Saw too many bugs (It overlooks a creek and has a nice backyard view, but with that creek comes bugs so I pay for monthly pest sprays)Mice infestation (I paid for a comprehensive $6k package to take care of this)House cleaning (she didnt like the cleaning that the pest control did so I hired full house cleaning for her)Second house cleaning (for the end of the pest process, I have the maid giving me an update on if they're clean tenants or not)Mold Inspection (she claims there's mold so I did a mold check and it was 100% clean)Toilet Leaking (I paid for a plumber but isn't this a tenant expense?)

And create opportunities for individuals that aren't using all this loose cash that is circulating.
