When you select an Heating as well as A/C service plan with your local heating and a/c business, always be sure to learn the great print, and ask for more information on your heating and a/c service plan. I made this mistake when I got mine. I did not realise that the Heating as well as A/C service plan I had selected was not a forever kind of thing. The Heating as well as A/C service plan did not renew automatically as I thought, so, at the end of the first year, since I did not call the local heating and a/c business to tell them that I wanted to re-enroll, they canceled my Heating as well as A/C service plan and I didn’t think it! When it came time to have some heating and a/c tune up labor done, I did it not knowing I was no longer signed up to the Heating as well as A/C service plan! You can imagine my surprise when I got a bill for the heating and a/c tune up work! I thought there was maybe some kind of error on their end. However, this is when I found out that I no longer had the Heating as well as A/C service plan, and that it was my responsibility to resign and repay manually! I was entirely angry at first…so angry that I almost decided to look on the internet for a new heating and a/c business to take care of all of my heating and cooling needs! But after I thought about it, I see it was my fault. I should have asked more questions, and learn the contract carefully.
