Air conditioning systems that are installed for central cooling and heating applications have a designated shelf life after which it has to be replaced. No matter what brand you install the rule is the same because normal wear and tear and user abuse have all been factored in determining its life span. But this does not mean that the system will die out. Instead, it can make you bleed by losing its efficiency that can inflate your energy bills alarmingly. Since the cooling and heating system is the single biggest user of energy in households careful thinking is required to decide when it is right to replace it.
Another reason for replacing it is the need to stay in tune with the latest technology. Needless to say, technological advancements are meant to bring down cost and if your system is about a decade old you could be missing out on several money saving opportunities that are incorporated in the new air conditioning systems.
How would you know that it is time for replacement?
While ageing of equipment is one of the reasons to think about upgrading the energy efficient air conditioning system there are some physical signs too, that users are likely to experience. If the cooling is not adequate despite maintaining the operating conditions at the optimum levels, it is an ominous sign that the system has exhausted its life span. But replacing the system is a costly affair and it is always better to seek advice from professionals to gauge the health of the system before it can be concluded that replacement is necessary.
Technical evaluation is needed
While your feelings and experience are important indicators it cannot be considered to be reliable enough to base your decision upon it. Hence, the system has to be evaluated by technical people who can assess its health in measurable terms. By quantifying the operating parameters as it exists, the air conditioning professionals can make a more objective evaluation that will be useful to substantiate the decision that you take.
The air conditioning system comprises of the heating and cooling units along with its accompanying distribution system that comprises of ducts. Hence, concentrating on the heating and cooling systems alone to determine the system efficiency can be quite misleading. Only professionals can evaluate the entire system by taking into consideration the layout, construction and ductwork so as to identify the root cause of the problem. It may so happen that the system efficiency can be worked up by addressing to duct problems and replacement of the air conditioning system might not be required.
Looking at the bigger picture
Only professional air condition experts are able to look at the bigger picture that can actually save money for you. Either you need not replace the entire system but only make partial replacements of weak sections like ductwork or make changes in the layout to enhance system efficiency. Even if you replace the complete system, the experts will help you to avoid earlier mistakes and select the most efficient system that can save energy and cost while operating at peak efficiency.
