An HVAC system keeps you warm in the winter and cool during summer, which is why it’s necessary to ensure that it’s working properly. Although their impact on your life may seem small, these adjustments to your home’s temperature levels can keep you safe from sickness and uncomfortable lifestyles.

Understandably, many homeowners don’t want to let go of their HVAC systems, especially if they’ve had it for a long time. However, it’s necessary to invest in an upgrade if your current unit is no longer working in prime condition.

When should you replace your home’s HVAC system?

Like any appliance, HVAC systems will wear down over time. No amount of regular maintenance and frequent repairs will extend an HVAC system past its lifespan. Being stubborn about keeping your HVAC can do you more harm than good, which is why you should know when to let go of it.

In this article, we will share four telltale signs that your home is due for a new HVAC system.

1. Higher energy bills

A common telltale sign that you need to upgrade your appliances is higher utility bills. Understandably, most homeowners blame the seasons for high energy uses. Electricity usage during summer and winter generally have the highest energy consumption rates for any household. Although electricity rates fluctuate over time, they won’t dramatically increase unless you have inefficient appliances. If you’re suddenly experiencing a spike in your electricity bills, you should double-check if your HVAC system is to blame.

2. Uneven temperatures in your rooms

Uneven temperature levels in your room may indicate problems with your system’s ductwork. For example, if your kitchen is much colder than the living room next door, your HVAC may be short cycling. It happens to HVAC systems that can no longer accommodate large areas. Since your system can’t reach all your rooms, the humidity will remain and linger in some places.

3. A non-stop functioning HVAC

Having your HVAC running non-stop can be a sign that it’s no longer in its best condition. Although you may feel comfortable with your indoor temperature levels, it may be a sign that it’s stuck with its current settings. If you can’t shut it off regularly, it could be a sign of dirt buildup that’s clogging your systems. Besides dirt and contaminants, you could also have an issue with your compressor with damage from wear and tear.

4. Your HVAC system is way past its prime

It’s common for older units to require frequent repairs, especially if it’s an exceptionally sturdy model. However, no amount or repair work can bring your HVAC system back to its prime. The estimated lifespan for these heating and cooling systems last around 10-15 years. If your HVAC system came with your house’s purchase, it could already have a few years on its belt.

It’s generally not worth spending money on repairing an older system, especially if it’s cheaper to buy a more modern model. Some older units that still use R22 refrigerants will be phased out by 2020, so it will be much harder to find repair services for these HVAC systems.


Even though your HVAC system is working well now, it’s better to replace it if it’s running past its lifespan. Anticipating potential problems it could have will be a better investment for your home in the future. It’s best to get a professional opinion from an HVAC technician to ensure that you’re making the right choice.
