Working for an HVAC supplier can be quite interesting, and every year, the two of us go to HVAC conferences across the county, however and one of the main reasons for the HVAC conferences is to learn about the latest in HVAC technology… It’s important to always keep up & suppose what is modern & decreasing in your line of work, gone are the afternoons where people used large ACs & complex heating systems, the modern HVAC technology makes it easier to cool or warm your home, our boss has been in the HVAC industry for 4 decades & is always sharing interesting things about the advances; She says he’s seen heating & cooling systems become more efficient & easy to use. However, they are much more complex to repair if & when there’s an issue. I remember one time she was talking about the first smart control component in her home. Our boss was so excited to get rid of the outdated dial system & use a smart control component at her lake house. She had to learn from her grandson how to use it, & set the app on her phone. The first time she had an issue with the smart control component was when our boss l acquired about the complex system. She thought she could repair the smart control unit, however it wasn’t that easy. Instead, she had one of the HVAC experts come in to check the smart control component & figure out the problem. After that, our boss took it upon himself to master how smart control units work, & can now work on them with her eyeah closed… But she still admits that HVAC technology is advancing fast.
