If you are thinking about trying to cut corners and do any kind of work on your central heating and air conditioning system by yourself, don’t do it! You could end up making matters worse and costing yourself a fortune in the end of things. Especially when it comes to ductwork and air duct cleaning. I had a friend of mine try to clean their own air vents and ductwork and in turn, they ended up damaging their entire central heating and air conditioning system and it cost them several thousand dollars to invest in a brand new and very up to date central heating and cooling system unit. Do not let this happen to you! I have always been smart and never cheap when it came to my central heat and a/c unit. Because I know I am not a certified heating and cooling specialist and I could never fix an HVAC unit nor would I even attempt to! If you are wanting to save money on HVAC repair or anything related, simply inquire with your local heating and air conditioning company about their heat and a/c service plans. Every single heating and air conditioning company in the country has them available. This is a way to save money on all kinds of heat and a/c work. These HVAC service plans may not be for you or your needs, however it does not hurt to inquire, because sometimes they can work something out for you and create an HVAC service plan that will fit your needs. Even if it is not part of their regular HVAC service plan.
