Unfortunately, HVAC systems don’t last forever. Like everything in a house, the heating and air conditioning system will need to be replaced eventually. But how can homeowners know if they are nearing that point?
8 Signs that Your HVAC Is Ready to be Replaced
Here are the main warning signs that it’s nearly time to replace the HVAC system in your home.
1. The HVAC System Is Aging.
The Department of Energy advises updating an HVAC system after 10 years of service. Though some newer, energy-efficient units may run fairly well for up to 15 years. Check when the HVAC systems was originally installed to know its true age.
2. Repair Costs Are Skyrocketing.
When a trusted HVAC tech gives you an estimate that’s particularly high, this could indicate that it’s time to replace the system altogether. If the cost to fix it is more than half the price of a new system, at that point, we recommend replacement.
3. Performance Is Decreasing; Energy Costs Are Increasing.
Rising energy costs are a sign that the HVAC system is now working harder to reach the same temperatures as it was able to produce years before. If you are spending more on heating in the winter or cooling in the summer when compared to the same months last year and the year before…it may be time.
Programmable thermostats and yearly HVAC tune-ups help maintain energy efficiency, but around the 10-year mark, homeowners are likely to notice reduced performance.
4. Indoor Temperatures Vary.
As the HVAC system gets older, it struggles to deliver the same heating and cooling power. If you notice that some rooms are hotter or colder than others, the need for replacement may be on the horizon. In the meantime, air balancing can help even out the temperature differences.
5. Air Quality Is Poor.
Running the HVAC system, when it works properly, should improve air quality. Adequate ventilation is a sign that the system is functioning well. When homeowners start to notice excessive amounts of dust on the surfaces in the house, in the air, or even the smell of dust, it’s symptomatic of an older unit. Similarly, high levels of humidity and musty mildew and mold odors point to replacement as the best solution.
To extend the life of your unit and improve air quality, try switching to a high-efficiency media filter.
6. The Furnace Has Become Noisy.
When an HVAC system is well maintained, it runs quietly. Older systems, with components that are starting to wear out and fail, can make noises. If the furnace starts clicking, grinding, rattling, or squealing, these sounds are cause for concern. Schedule servicing as soon as possible when it produces new noises. But be prepared, because HVAC replacement may be in the near future.
7. The Air Conditioning Unit Relies on Freon Refrigerant.
The Environmental Protection Agency has decided to block the production of Freon (R-22) as of January 2020. Newer HVAC units have already started utilizing more environmentally friendly refrigerants. But AC units that are more than 10 years old are more likely to still run on Freon. Homeowners with these outdated cooling systems will be required to retrofit or replace them.
8. The Heat Pump is Icing Up.
Frozen coils and frost are fairly common problems. This can happen occasionally when exposed to extremely cold temperatures in the winter. If your heat pump has iced up multiple times or is freezing with some regularity, this is another sign that the system is nearing the end of its life.
