we have kept ours in renewal for 26 years, its about 192.00 each year. we have had to have them retreat areas 3 times and there has been no cost to us. i think we are the only house on the street that still has one. 12 homes on the street.
at least you have access to clean it out. the the water moves very slow and will build up gunk. just like your home ac. we run into this in the restaurant industry all the time
i just finished up my install of a Tosott brand, had good reviews. i had the garage down to 76 degrees in about 2 hours. this is in Florida it was about 96 with heat index. i bought direct from them
i had 1 bucket of an endloader put in my colorado, first i laid a tarp down, then put 5 gallon buckets in the bed. after i dug the buckets out and some dirt i was able to pull the tarp out. had it been just the full load i dont think it would have worked
