If you are asking yourself the infamous question of how long a central heating and air conditioning system can last, the technical answer is around 20 years.
However if you take extra care of your central heating and air conditioning system unit you may be able to squeeze an extra decade out of it going as far as possibly 30 years! If you are not concerned with having the latest and greatest in heating and air conditioning technology this can be a good thing and you will save yourself from having to invest into a brand new and extremely up to date as well as very expensive central heating and air conditioning system unit.
Taking extra care of your current central heating and air conditioning system is not hard at all so long as you pay attention and get all of your heating and cooling maintenance done. This includes but is not limited to getting your central heating and air conditioning system unit tuned up and checked up every 6 months or so. Then also ensure that you get your central heating and air conditioning system unit’s ductwork cleaned at least twice a year. If you do these kind of things you should have no issues at all with having your central heating and air conditioning system last an additional 10 years past the technical lifespan! Like I said in the beginning, this can be a very good thing if you are not obsessed with the latest and greatest in heating and air conditioning technology.
