A lady I used to work with had to take a afternoon off work one afternoon; I assumed she was feeling under the weather, so when I saw her the next afternoon, I asked how she was feeling. She explained that she had not been sick, but rather, she had to stay lake beach house because the Heating and A/C repair guy was stressed to come out. She traveled a lot for work, and when she got lake beach house from her most recent trip, she walked into a hot and humid house. It seemed that at some point while she was away, her A/C device had called it quits. The Heating and A/C maintenance guy came in as stressed that day, but the injure was pretty extensive, and she had to get a pretty pricey A/C device repair. I guess they had to replace the A/C device condenser and maybe a fan or two, in addition to something to do with the thermostat. I guess she was shocked when she got the Heating and A/C repair bill that afternoon. The guy that did the repair spoke to her about their annual Heating and A/C maintenance plan while he was there, and she bought it. She told me all about it, and that was the first time I had ever heard of such a thing. It is a repair agreement that provides an Heating and A/C tune-up every year, correct maintenance, and free repair calls if something breaks. I never knew you could get an Heating and A/C tune-up, just enjoy you do on your car, and that was the first I had ever heard of it. Now that I know, though, I have decided it is a good idea, so now I get the heating and cooling maintenance agreement, too.
