Typically if a system is over (8) years old and you are facing repair charges of $400 or more you need to take a hard look at replacing your existing system. What happens often is that we continue to repair our existing system in hopes of making it like new but it just continues to become less and less efficient and the repairs bills continue to add up. Often times you can pay for a new system over a relatively short period of time with the energy savings alone. In fact, in January 2006 the EPA adopted new guidelines stating that all new residential home systems had to be a minimum 13-SEER efficiency rated.
The temptation is to do the “quick fix” to get by and hope the existing system holds up for another year. Keep track of how old your system gets and when it gets past that (8) year old mark then consider replacing it when the next big repair bill comes. Chances are that it will continue to break down once it reaches a certain age.
Ultimately the issue comes down to comfort and comfort takes on many shapes and sizes. It’s important to continually ask yourself if your current system is giving you the comfort you are looking for whether it be the actual temperature or things like the dust levels in your home. Are you being bothered more and more by your allergies? If so, it may be time to upgrade your system with an electronic air cleaner or media filter.
