If your heating or cooling system is old, not working properly, and constantly in need of repair, it may be time to replace it. Wear and tear over time can cause your system's efficiency to drop drastically. Save money on your utility bills and maintenance with a new and efficient system.

When is the best time to replace my existing system?

There are many factors to consider when choosing a new system; it is important to ensure that the unit you select is of the proper size for your home. You should also keep in mind your family's comfort and the load calculation for your home to get an efficient system. In case you are prone to allergies, an indoor unit with an ECM motor can be installed which continuously filters the air entering your home. It is also important to keep in mind your budget parameters and your long term need for the system during the purchase.

With regular preventative maintenance and service from a competent professional, your average air conditioner should last 12-15 years or fewer and a gas furnace can last up to 20-25 years. The average age of an industrial or residential heating or cooling unit is entirely dependent on the working areas and conditions, frequency of use, regular maintenance, and other factors that vary from case to case.

How long do new systems usually last?

Determining whether it is time to repair or replace your old air conditioning or heating system can be difficult. Below are few key points that should be kept in mind while deciding whether to repair or replace your old system.


How old is your system?


If you have been using the same system for years and it has been frequently breaking down and giving you trouble, the problem may be due to gradual wear and tear of internal components due to age. The life expectancy of a system varies and is dependent on a variety of factors. If an old system has broken down once, it is more than likely that the same will happen again. If you want to avoid replacing the system, then you should ensure that you get repairs done from a qualified technician and not just a quick fix.


How much is your operating cost?


Your system's operating cost is also an important factor to consider when deciding on whether to replace or repair your system. You must keep in mind that even after repairs, your system will maintain its current level of efficiency. Most units built today are created energy efficient which may help you save up to 60% on your energy bills. Therefore, opting for a new system may help you save a lot of money in the long run.
