If your AC is making strange noises, struggling to cool your home evenly, or driving up your energy bills, you may be wondering when to replace your air conditioner.
Not only should you proactively replace your A/C, but you can use the opportunity to swap out your old air conditioner with a high-efficiency heat pump. One that can keep you cool in the summer and warm in the winter—all while lowering your bills and increasing your comfort.
Better yet: if you plan ahead, you can avoid hot, summer days without a functioning A/C and can take advantage of available government rebates.
So let’s dig in. What should you look out for when evaluating how well your A/C is functioning?
🔊 1. Unusual Noises or Smells
If your AC is making new, strange noises—banging, grinding, buzzing—or you’re noticing a burning or musty smell, it’s time to call your HVAC technician. These symptoms often point to serious internal wear, mould in the coils, or electrical issues. Don’t ignore them.
🌡️ 2. Inconsistent Cooling or Humidit
Does one room feel freezing while another is too warm? Or does the air feel muggy even when the system is running? This is a common red flag that your system can no longer maintain balanced temperature or humidity, especially in older homes. It might be time to consider a home energy upgrade or a new heat pump.
💨 3. Weak Airflow
If the air coming from your vents feels weak or barely noticeable, it could be due to a failing compressor or clogged ducts. Either way, it’s a sign your system is underperforming—and may not last much longer.
🔁 4. Frequent Breakdowns or Repairs
Needing to call your HVAC technician once a year for a quick check-up is normal. But multiple repairs in a single season? That’s a sign your AC is no longer reliable—and that money might be better spent on a long-term replacement.
💸 5. Rising Energy Bills
If your electricity bills are climbing each summer, even though your usage hasn’t changed, your AC may be losing efficiency. Many homeowners in Canada are switching to electric heating and cooling solutions like heat pumps to reduce energy costs and cut their emissions at the same time.
📆 Bonus: Your AC is Over 10 Years Old
Most traditional air conditioners last about 10 to 15 years. If yours is approaching or past that range, it’s worth considering a proactive replacement—especially if you want to take advantage of energy rebates before they expire.
