HVAC systems allow us to quickly identify whether they are functioning properly or not. If you find that they are not functioning properly, you don’t always have to replace the entire system right away. An HVAC system is divided into 3 parts: an outdoor unit, an indoor unit, and ducting that connects these units. So it’s a good idea to first find out exactly where the cause of the problem lies. However, sometimes even if you do find where the problem lies, you will still need to replace your HVAC system. In this article, you will learn when it is time to replace your system and when it is worth repairing it.
When To Replace Your HVAC System?
When to fix your HVAC system?
If your system has less than 10 years
The National Association of Home Builders estimates that the average lifespan of an HVAC system should be between 10 and 15 years. It is possible that your system has broken down but it will most likely be a minor repair.
If your system is regularly maintained
There are many components in your HVAC system that need to undergo regular maintenance or replacement. Examples include filters that trap dust, fungus, mould, and even cigarette smoke. So it’s a good idea to have your system serviced frequently in the fall and spring.
If you are uncertain whether your wires are working properly
As mentioned before, the indoor and outdoor units are connected by wires, and they may be the reason for ineffective maintenance of the desired temperature in the room. Investing in a professional duct inspection and sealing any gaps for about $50 can make your HVAC run more efficiently with a relatively inexpensive repair.
When to replace your HVAC system?
If your system has more than 10 years
HVAC systems can last up to 10 – 15 years. Everything depends on how you take care of your system in the first place. An average cost of a new unit typically is in the range between $5000 and $8500. This is not a small investment, of course, but it also means a new, more efficient unit.
If your energy costs are increasing
Your electric bill will obviously change from month to month during the year. However, if the efficiency of your system starts to decrease, you will definitely notice a difference in your energy costs. A less efficient system means your HVAC is working overtime to heat and cool your home, which means it costs more. Therefore, it might be better to just replace the system at some point.
If the temperature in your house cannot be maintained at a certain level
If you can feel that the temperature in your household rooms is different from your normal temperature set up or if you have to regulate your device much more than you are used to, then you may have to replace your HVAC system. Another sign to replace your HVAC system is if your unit needs to run during the day and night to keep the desired temperature.
If your outdoor unit is exceptionally noisy
The outdoor unit is doing most of the work in your HVAC system. A new unit or a well-maintained one runs quietly. If it starts becoming noisy, it is recommended to have your device serviced. However, in most cases, it means it is time to replace your system.
Your home gets dusty easily
The role of the HVAC system besides heating and cooling is also keeping constant ventilation. It does this by removing dust and dirt from your home. If you see that there is more dust in your home after a relatively short amount of time, it might also mean your system is not efficient anymore and needs replacement
So what to do?
It is quite simple! At the end of the day, we want to do what is more cost-effective, right? We recommend estimating the costs of fixing your HVAC system and multiplying that by the number of years your system already has. After, you may want to compare the obtained amount with the price of the new unit. If preparing your HVAC system costs more than installing a new one, then replace it.
