It makes no sense to hang on to an old AC when all you do is constantly fix broken components.
The regular repair charges that go into your HVAC technician can get you a new unit that serves you better. Many old folks grapple with. I do not know if it is an attachment issue or there is more to it. From experience in this field, many are never willing to let go of their old models of HVAC units even when they are inefficient and responsible for their high monthly energy bills. It takes a lot of energy to convince them that a simple air conditioner change could result in better heating and cooling of their houses. Sadly the reality is that your HVAC system will not last forever, no matter how good it was when you first bought it. These gadgets are created to last a decade and a half or two if you are lucky. Even so, the longevity of your air conditioner or furnace depends on how well you maintain it. If you hardly remember to change the furnace filters or even cleaning the air ducts, your system will not last long. However, even those with excellent maintenance routines must understand that the machines give up after a long time of faithful service. At such a time, homeowners should consider upgrading to newer and better versions of ACs, preferably those that come with smart thermostats. Talk to an HVAC business to understand what works best for your house, depending on the insulation you have, the size of the rooms, and other crucial factors that affect your final choice.
