I have trouble changing a/c filters

I care about my job, however no job is perfect.

I drive a university bus for a living.

I live in a relatively small town, & the people are so kind. They take care of their children & teach them manners & how to behave on the bus. I have only had to write up a child for misbehavior one time in my entire work, people often tell me that I am silly for loving my job as a bus driver, however they do not understand how well behaved the children on my bus are. The only thing that I do not like about working at the bus garage is that I do not have work for the summertime. It is not that I need the money, however rather that I need something to do while in the summer time months. I like to keep myself busy. Last summer, I did some HVAC work, but well, it was not undoubtedly HVAC work because all I did was wash air conditioners for the entire summer. I worked in a few businesses that a friend of mine owned, & there were a total of two hundred & fifty individual a/c units in the buildings that I worked on, cleaning & maintaining the air conditioners was all that I did. I had no experience prior which I did not guess would be a problem because I was just going to be cleaning air conditioners all morning long. I was asked to change the a/c filters in particular air conditioners throughout the buildings, & it was quite a challenge for me. There were uncommon brands & units, so I had to figure out how all of them worked & which filters were needed. I am cheerful I was able to keep busy, but I do not guess I will do that job again.
