Are these worth paying for if you dont know much about your central air system? The extent of my knowledge is that I know to change the filters once a month, and I get the leaves and grass off the condensor on the units outside.
The folks i use want like 180/year for 2 inspections per year to maintenance my system (I have dual ac/dual furnaces). Its less for one system.
I did get it last year, and it seemed like my bills did drop some, but I dont think the units had been serviced for years. I'm thinking maybe skip every other year
I was just wondering if i can get by cheaper on this. Should i just go buy a book that will teach me how to maintenance them myself? If its complicated, i wouldnt want to do it.
