Your HVAC system, like a trusty companion, works hard year-round to keep your home comfortable. But just like any companion, it ages over time, affecting its performance. So, how old is your HVAC unit? Knowing the age of your heating and cooling system is crucial. In this guide, we’ll explore the subtle signs of aging that may surprise you. Join us on this journey to better understand your HVAC’s age and what it means for your home’s comfort.
How to Determine your HVAC Unit’s Age
Most HVAC units maintain their quality for 10 to 15 years, so if you’re wondering about the manufacturing date of your unit, you can peek at the branded nameplate on the side of the unit. If you don’t see it, you can also try Googling the serial number or calling the manufacturer directly.
Assessing Your HVAC’s Lifespan: Service or Replace?
While knowing the exact age of your unit may be beneficial, the number of years it will last depends on how well you care for it by doing things like regularly changing the air filters and cleaning leaves out of the fan after a storm, and how often you have it serviced by a technician.
If you’re curious whether you should service or replace your HVAC unit, here are a few questions to ask yourself:
1) Has your utility bill increased in recent months? If so, this could mean that your air filters need to be replaced or that you have loose air vents. On the other hand, you may be facing some electrical issues, making your unit less effective. The older your unit, the more effort it must put toward achieving the same results.
2) Have you found yourself calling a technician more times than normal this year? A good rule of thumb when it comes to servicing your HVAC unit is to get it checked right before it’s extremely hot (summer) or frigidly cold (winter). If you’ve already had multiple technician visits in the last year or so, it might be time to replace.
3) Are there any funny smells or noises coming from your unit? If your unit sounds like creaking floors in an old house, or if you smell weird, moldy, or burning odors, your HVAC unit is likely to blame.
If you answered “no” to all three questions, then you have a quality HVAC unit on your hands! If not, then we suggest having your unit evaluated to find out whether servicing or replacement are right for you.
At any point, if you find yourself with concerns or questions about your unit, don’t hesitate to give us a call here at Exxel Mechanical Services.
How to use a SEER rating to find the age of your HVAC unit
You may know how old your unit is based on the manufacturing date, but just how old are we talking in terms of quality? The best way to find out is by looking for its SEER rating, otherwise known as the Seasonal Energy Efficiency Ratio. More specifically, it is the ratio of cooling output throughout the cooling season.
Generally, the higher the SEER rating, the more efficient your unit should perform. A higher SEER rating is typically about a 16, whereas a lower rating is 13, which indicates a less expensive and less efficient unit. This rating is the federal minimum to be sold. Some manufacturers will list this number along with the manufacturing date.
Keep in mind that the more up-to-date and efficient your unit is, the less costly it will be to run. Whether AC or other types of equipment, the longer you run any kind of machine, the more energy it takes to operate at its optimal level.
How to make your HVAC unit last longer
Just as you could say a 50-year-old man has the athletic prowess of a 35-year-old man, it is possible for a 15-year-old unit to act the same as a 10-year-old unit. Age doesn’t have to be the only determining factor when deciding when to replace your system.
There are several factors that can shorten or lengthen your unit’s lifespan, such as how often you run the unit, the temperature at which you run it, and even the number of times you turn it on and off in a day.
When it comes to extending the typical lifespan of your HVAC unit safely and efficiently, there are a few simple things you can do. We recommend scheduling regular maintenance appointments twice yearly to check for damage, errors, or other issues. Beyond that, you can replace your air filter(s) at least every 3 months, keep your outdoor unit free of encroaching vegetation, dirt, and debris buildup. Doing all these things can prevent future high-cost repairs and ensure a long life for your equipment.
Even if you’re taking stellar care of your HVAC system, it’s still important to keep your eyes open for certain changes in and around your house to catch small issues before they become big problems:
-
- Accumulation of dust could simply mean you need to change the filter, but if humidity is present, it’s best to call your technician.
-
- A room that won’t properly cool or heat is usually a red flag for poor insulation, a damaged thermostat reading, or a clogged filter.
-
- Poor efficiency after an intense storm could indicate a leaf and debris pile up in the unit, preventing the fan from working correctly.
