Ants are in season. If you are being attacked, put it in the suggestion box. Likewise, if you have good way to get rid of them put that in the suggestion box also.
Watch the age of your hot water unit. It is much better to replace before the tank ruptures.
All A/C's have a drain line. (That's where the humidity goes.) If no preventive maintenance is done, in time the line will clog shut. Put vinegar or clorox in your access port every 6 months. Some recommend 3 months. Very easy to do !!
