I am really not good about having my HVAC system looked at. A lot of times I try to be smart about doing HVAC maintenance, but lately I have been really bad about it. The main thing that I don’t like about doing HVAC maintenance is the high cost of paying for an HVAC technician. I tried to learn how to do some HVAC maintenance on my own but I was rarely successful and I ended up messing up my HVAC system more than I fixed it. When I went to call my HVAC technician I realized that I had put the air filter in the wrong way and it was jammed inside. Luckily that time my HVAC tech cain was able to help me out and that was the last time that I tried to fix my own HVAC system. I know it might seem silly that I can’t fix my own HVAC system, but it really is complicated. I know that you can look online for tips on how to fix an HVAC system but if you have ever looked it can be confusing. There are so many HVAC parts and I really just can’t keep track. To me it feels like there’s so much that’s always changing in the HVAC industry. My recommendation to you is that you try to get a service contract with your HVAC technician so they will come in a few times a year and do routine maintenance on your HVAC system. If you keep all of your HVAC parts up to date you are likely to have an HVAC system that will run for a very long time and have no problems.
