When will an existing HVAC system suffice, and when will it not? When should you buy a new system for your home?
If you own a relatively new HVAC system, you may have very little to worry about. Most likely, your system just needs a check, a cleanup, parts replacement, or a combination of these. Perhaps, your system is still covered by its warranty.
The answer to the aforementioned questions becomes murkier when you have an older system installed in your home. There are numerous factors at play that you have to individually consider before making a final decision. Plus, when you add the issue of money, making a decision is never easy.
Definitely, your answer will affect your finances and your family's comfort, especially during summer and winter. And as such, you have to carefully weigh your options.
What factors do you need to consider?
How old is your system?
One of the most important factors that you need to consider when your HVAC system breaks down, and you're mulling over having it repaired or getting a new one, is the system's age.
HVAC experts recommend replacing systems that are 10 years old or older. Others say that a system that is already 15 years old (or older) should be replaced.
One quick way to simplify the decision-making process is to factor in the age of your HVAC system. Multiply its age by the repair cost quoted to you by the technicians. If the number you arrive at is more than $5,000, then that simply means that you should replace your system.
Price of the refrigerant
There are some instances wherein your AC system will require the topping off of its refrigerant. In most cases, this isn't simply a matter of topping off your unit's Freon. Rather, it's a sign of a coolant leak.
Apart from the cost of the refrigerant, you may also have to pay for the replacement of the part that has developed a leak. In most instances, you may also have to replace your compressor.
When you add up all the costs, the number you arrive at will be equivalent to the price of a low-end system.
Other factors to consider
Take into account how often your system breaks down, as well as your energy bills. More often than not, it's more economical to invest in a new, more efficient system rather than to rack up expenses over and over again due to frequent breakdowns.
On the converse side of the coin, if no leaks have been found and your monthly bills are relatively low, you can possibly eke out a few more years from your current system.
Still unsure? Consider contacting local HVAC professionals. They can give you an honest evaluation of your current system and help you make an informed decision on this matter.
