I live in a warmer temperature, and only need to run my gas furnace for a few months out of the year, if at all. Because of this, I rarely worry about my gas furnace, as it has consistently turned on when I needed it to, last fall, however, we had an unusually cold weekend, and when I went to turn my gas furnace on, I only felt cold air coming out of my vents. Naturally, I did what I always do when something breaks, and turned to YouTube, then the woman in the video made it look straight-forward enough- remove the defective part, update it with a new one, and the gas furnace should be working like new. I went to the hardware store and bought the new part, and removing the defective area was straight-forward, but when I got the new piece in, however, my gas furnace was still blowing cold air. I spent the rest of the afternoon watching more YouTube videos and buying more Heating and A/C parts, but I couldn’t get my gas furnace to come back on. That evening, my family had to sleep with space heaters on just to stay warm. In the afternoon, I finally decided to call my local Heating and A/C provider, and ask for help. They were able to send out a Heating and A/C worker quickly, and she had my gas furnace warming my home in no time. The Heating and A/C worker told me that the best way to prevent that from happening again was to schedule proper inspection and repair of my system. Next time something breaks, I will skip the YouTube videos, and call a professional right away.
