The average lifespan of an HVAC system is 10 to 15 years. If your system is already this old, you may already be thinking about HVAC system replacement costs. But how can you know for sure that it's time to replace your HVAC system? To get started, there are a few key questions you can ask to help you know when it's time to make the switch. Once repairs outweigh the cost of replacement, your current system fails to maintain a comfortable temperature, your energy bills increase, or health hazards appear, you will know that your current system isn't functioning properly and it's time to replace it. Here are the key questions to ask when replacing an HVAC system. 

Will Repair Costs Outweigh Replacement? 

The first question to ask when determining whether to repair or replace your HVAC system is: will the cost of repairs outweigh the cost of replacement? To truly answer this question, you will need to consult with a professional. They will be able to help you weigh the pros and cons of each option and make a decision based on your specific situation. Generally speaking, however, if the cost of repairs over the last year has exceeded the average cost to replace your HVAC system, it’s probably time to replace it. 

Can My Current System Maintain Temperature? 

If your current HVAC system can't maintain a comfortable temperature in your home, it's time to replace it. You may experience unusually hot or cold areas in your home that no amount of adjusting the thermostat will fix. Or, maybe your system seems to run all the time but the temperature continues to fluctuate. This is typically one of the first signs that your HVAC system is no longer functioning properly. 

Have My Energy Bills Increased? 

If you've noticed a significant increase in your energy bills, it could be due to an inefficient HVAC system. Older systems that aren't functioning properly tend to use more energy in an attempt to heat or cool your home. If you're noticing a spike in your energy bills, it's time to consult with a professional about replacing your HVAC system. It may be better to pay the HVAC replacement cost in the short term, rather than face high energy bills for years to come.

Does My Current HVAC Create Health Hazards?  

If you or a family member has developed respiratory problems since using your current HVAC system, it's important to have it inspected by a professional. Signs that your HVAC system may be contributing to your health problems include: 

  • Too Much Dust. If you've noticed an increase in the amount of dust in your home, it could be due to your HVAC system. Your system may be circulating dust and other particles through your home, which can aggravate allergies and respiratory problems.  
  • Odd Smells. If you notice any strange smells when your HVAC system is on, it's important to have it inspected as soon as possible. These smells could be indicative of a larger problem, such as mould or mildew growth in your system. 
  • Poor Air Quality. If you've noticed a decline in the air quality in your home, it could be due to your HVAC system. Poor air quality can cause a variety of health problems, so it's important to take action if you notice a decline.
