Central A/C or Swimming Pool Pump the problem?
The past two years my summer electric bills have increased significantly. I keep track of all my utilities, and therefore, have my kWh usage for the past six summers.
2006 - 10,250
2007 - 10,700
2008 - 8,049
2009 - 9,545
2010 - 12,425
2011 - 13,356
Two things happened in 2010, that I am wondering might be part of the problem. My A/C unit failed, and the HVAC repair person made a temp fix and told me it would last one week. Another HVAC guy told me it could fail in one week or three years. It continued to work in 2010, and all of 2011.
I also had to replace my swimming pool pump, which I replaced with an exact duplicate, Hayward 1.5hp 2-speed. I purchased a Kill A Watt monitor, but it is a plug in type, and both the A/C & Pump are hard wired, so I can't use the it to test the draw.
The house was built in 1998, and the A/C unit is builder grade, along with the furnace which actually has a date of 2006 on it.
I really want to learn what is causing the problem and fix it or replace it. BTW, I also have a hot tub, which was not turned on last year solely because of the utility costs.
I would greatly appreciate anyone that can tell me where to begin.
