5 Signs Telling You It’s Time

It’s old 

If you’ve clicked on this article, you might be experiencing an issue with the way your HVAC system performs. The first question your HVAC technician will ask during your service call is: How old is your HVAC system?

HVAC systems tend to have a lifespan of between 10-20 years. Systems that have been serviced regularly run longest and most efficiently. However, bear in mind that as a system ages, reduced efficiency and repairs become factors in your decisions moving forward. If your system is older than 10 years and you’re facing many medium-to-large repairs, HVAC replacement might be a better option.

It’s Inefficient 

You might notice your HVAC system’s inefficiency in the running costs, but you can also tell if your HVAC is not working properly by the following:

  • The amount of time the system is running or the fan is blowing 
  • If your system seems to struggle to keep the temperature consistent 
  • Evidence of  increased dust piles
  • A noticeable higher than comfortable humidity level 

While these issues might point to a specific HVAC issue, they can also impact the overall efficiency of your unit’s operation. Depending on the age or severity of the issue, you may find it’s time to replace your HVAC.

Cost to Run: Repairs & Monthly Bills 

Costly repairs or high monthly bills are two big reasons to consider HVAC replacement. Here’s a general rule for making the decision to repair vs. replace:  Replace your HVAC system if the repair costs are more than half of a new system. 

Monthly bills should also stay consistent year to year (while accounting for things like fuel cost increases and inflation). For example, if this summer you notice a substantial increase in your bills compared to last summer, this may indicate that something is going on with your HVAC system. 

To stop habitual repairs and costly monthly bills, replacement might be the way to go.

It’s the Wrong Size 

If your system can’t keep the whole house at a consistent temperature, can’t keep different rooms at the set temperature, or achieves a temperature so quickly that it shuts down mid-cycle, it might be the wrong size unit for your home. 

That’s right! HVAC systems are not one-size-fits-all and having the wrong size unit can lead to inefficient operations. To remedy this situation, you may want to consult an HVAC professional about getting your HVAC system replaced so that it’s the right size for your home. 

There are Odd Noises & Smells in Your House

Grinding, hissing, or clunking noises are not good sounds to hear while enjoying time in your home, especially if they are coming from your HVAC system. Loose or broken parts within  your unit can be to blame, especially with older HVAC systems. 

Burning, sour, or foul smells–also not good to be experiencing in your house–may be coming from your HVAC system if something is wrong. Mold, melting pieces, a fire, or a dead animal in the vents could all be the culprit. 

If you have an older HVAC system or it’s going to take a major repair to fix the sounds or smells coming from your HVAC system, a new HVAC system might be in order.
