I have a certified heating and air conditioning contractor that I hire on a semi regular basis to do HVAC tune ups and check ups on my central heating and air conditioning system. I have been using this guy for the last 15 years or so. He is really great at his job and he is even better when it comes to any kind of heating and air conditioning repair I may need to have done in addition to the standard heating and cooling system tune ups and check ups. One thing that kind of annoys me though about my HVAC contractor is that he is always making a racket! Every Time he’s here doing any kind of work on my central heating and air conditioning system he seems to always be dropping his tools! I hear this crash, bang and clanking noise all the time and it gets annoying. Especially if the heating and air conditioning contractor is here doing work while i’m trying to do something. It gets so darn distracting. However I can not really complain too much because his prices are really great and like I said before, he really is a true HVAC professional and knows how to get the job done in a timely manner. There is never a question of will this guy make things worse. Every time he works on my central heating and air conditioning system, by the time he is done my central heat and a/c unit works as if I just got a fresh installation from a brand new and up to date heating and air conditioning system.
