If you work in the heating and air conditioning supplier as long as I have, you will find that you gain a wide range of experience and that sometimes the heating and air conditioning maintenance work you do may be more difficult than other times.
However, the same exact thing holds true for when you are performing heating and air conditioner replacement.
All things considered, HVAC work can occasionally be more difficult. Take the other day, for instance. It had been about 4 months or so since my last truly difficult HVAC maintenance task. But lo and behold, it finally happened again, at which point I discovered that fixing the central heating and air conditioning unit I was supposed to fix was much more difficult than fixing any other heating and air conditioning unit I had to fix. So, this was a very difficult situation. And whenever it does, I welcome it with open arms. I enjoy the challenge of taking on tasks like this from time to time that are more demanding than your typical daily heating and air conditioning repair. After years of working in the heating and air conditioning maintenance and replacement industry, it keeps my skills as a certified heating and air conditioning specialist current. In addition, doing a difficult heating and air conditioner repair keeps the brain active and gives you something new to attack. This is both my job and my way of life. And there is absolutely no other way that I would want it. Being a certified heating and air conditioning specialist is a rewarding and fulfilling career that calls for a lot of effort, dedication, and ongoing education to stay current with changes in the field.
