Spring heat = early AC

The unit on the left had a blanket of filth on three sides this is after only one year of operation....The one on the right had some but not as bad......It was weird to find it this way,there was nothing to indicate what the cause was, no drier vent,work shop vent or a exhaust fan.within 20' just odd.
Anyway this is the crap I was describing this will degrade the SEER rating and if not cleaned,over time it will cause damage so here are some before and afters.

5/0, it looks like the fan was put on backwards. The airflow is reversed.

Sorry I don't understand,are you referring to the coil's being packed?

The condenser air flow looks like this,the blue line represent ambient air going into the outside perimeter of the unit,this helps to cool the coil and transfer the heat,During the spring pollen,leave's and bugs get sucked into it.When this happens this will prevent the transfer of heat,it is detrimental to keep this clean,if you have shrubs,plant's or weed's that are within 18" or closer they should be moved or cut back.
The red lines indicate warmer/hot air being expelled from the unit.

Hope this help's.

Well after the big cleaning, as stated before the unit is working much better this year and blowing colder air!

But the big surprise was I just got my electric bill for July into August and they show last years to this year, last year at the same time for the same 29 days I used 1600 kwh, and this year i just 990 kwh!! Daily use went from 54.5 a day to 34.4 this year.

The cost was much better also as last year 7.3 per kwh and this year 6.8 kwh.
I never shut it off either! Not worth it to me unless it gets real cool out for a few days, cause then I have to dry out the air again. I bought the cheap filters and just change faithfully every 30 days, same all winter also.

The avg temp was 78* last year and 77* this year. So i have to say it again THIS WAS A GREAT THREAD!! Thanks!!
