The air conditioner just isn’t working

Yesterday I awoke to an Heating as well as Air Conditioning problem. As I went to the lavatory in the middle of the night I found a huge puddle of water on the floor next to my Heating as well as Air Conditioning closet. I thought maybe my daughter had knocked over something in the middle of the night and just didn’t scrub it up, to be honorable, this has happened before, once I did a little bit more research I realized that the puddle was coming from my cooling system. It seemed to be that there was a steady drip of water however I could not figure out what making the leak. I immediately called a local Heating as well as Air Conditioning supplier to come over and inspect my A/C, then however, I was not prepared for the result that I gained! The Heating as well as Air Conditioning serviceman arrived well after our appointment time. I decided to ignore it because I legitimately needed to figure out what was going on with my cooling system, then after the Heating as well as Air Conditioning serviceman showed up late, he was also not ready to do his task. He told me that the reason my cooling system was dripping was because the filter had not been changed and dust particles were building up. He said in order to unplug my Heating as well as Air Conditioning equipment he would need some kind of vacuum, but he did not have it with him. So he had to leave my apartment to go get his vacuum. This trip back to his shop took another few more hours, maybe he decided to stop for breakfast along the way. I could not understand the unprofessionalism from this HVAC serviceman. I will not be calling them to repair my Heating as well as Air Conditioning plan ever again!HVAC technology
