Is It Time to Replace Your Air Conditioner? 7 Signs You Shouldn’t IgnoreBy Clockwork HVAC | Ottawa Air Conditioning Experts

Apr 12

Ottawa summers are getting hotter—and when your air conditioner isn’t performing like it used to, it can turn your home into a sweatbox. But how do you know when your AC needs a simple repair... or a full replacement?

At Clockwork HVAC, we help homeowners make smart, cost-effective decisions about their cooling systems. If your AC is struggling to keep up, here are 7 signs it might be time for an upgrade.

1. Your AC Is More Than 10–15 Years Old

Most air conditioners last around 10–15 years. After that, even well-maintained units start to lose efficiency and become more prone to breakdowns. If your AC is approaching or past this age, it may be cheaper in the long run to replace it with a newer, high-efficiency model.

New systems can also qualify for rebates and deliver significant savings on your monthly energy bills.

2. You’re Paying for Frequent Repairs

One repair is normal. Two? Maybe bad luck. But if your AC is constantly breaking down and your technician is becoming a familiar face, it's probably time to stop sinking money into temporary fixes.

💡 Pro Tip: If repair costs are adding up to more than 50% of the cost of a new unit, replacement is the better investment.

3. Your Energy Bills Are Climbing

Have your hydro bills gone up—even though your cooling habits haven’t changed? As AC units age, they become less efficient, especially in extreme heat.

Today’s high-efficiency air conditioners use significantly less energy to cool the same space. By upgrading, many Ottawa homeowners see 30–50% energy savings during the summer months.

4. Uneven Cooling or Poor Airflow

Are some rooms too hot while others are freezing? That’s a sign your air conditioner is struggling to distribute cool air evenly—whether due to ductwork issues, a failing blower motor, or an underperforming unit.

Newer systems provide more consistent, balanced cooling—especially when paired with a smart thermostat and zoning features.

5. Your AC Is Making Strange Noises

Loud grinding, buzzing, or rattling noises coming from your AC are not just annoying—they’re often signs of internal damage, worn-out parts, or a failing compressor.

If your air conditioner sounds like it’s working harder than it should, it probably is.

6. The Air Isn’t As Cool As It Used to Be

When your AC is running but the air feels lukewarm—or it takes forever to cool your home—that’s a red flag. Refrigerant leaks, failing compressors, or clogged coils could be the cause.

If the issue keeps coming back, it’s a sign your system is no longer keeping up with demand and may need replacing.

7. Your System Uses R-22 Refrigerant (Freon)

If your AC was installed before 2010, it might use R-22 refrigerant, which has been phased out in Canada due to environmental concerns. Not only is it expensive to recharge, but it’s also no longer being produced.

If your AC runs on R-22 and needs repairs, replacing the system is almost always the smarter—and greener—choice.
