Should You Repair or Replace That Old AC? Signs It’s Time for an Upgrade

Your air conditioner has one job: to keep your home cool and comfortable. But if it’s making strange noises, blowing warm air or driving up your energy bill, it may be trying to tell you something. At Fonda’s Heating & Plumbing, we help Red Deer homeowners weigh one of the toughest HVAC decisions—AC repair or full replacement? 

We get it. No one wants to shell out for a new unit unless it’s absolutely necessary. But hanging on to an old or underperforming air conditioner can cost more in the long run.

The key is knowing when a simple fix will do—and when it’s smarter to upgrade. 

The age of your system is the first thing to consider. Most air conditioners are built to last around 10 to 15 years. After that, performance drops and efficiency plummets. If your unit is over a decade old and frequently needs service, investing in modern equipment may be more cost-effective than repeat AC repairs. 

Another red flag? Rising energy bills. Older systems often have low SEER (Seasonal Energy Efficiency Ratio) ratings, meaning they use more energy to do the same job. Today’s units are far more efficient—and Alberta homeowners may even qualify for rebates or energy incentives when upgrading. If you’re sweating through high cooling costs, it’s worth asking whether your AC is still pulling its weight. 

Frequent breakdowns are a sure sign it’s time to reassess. One or two repairs over several years is normal. But if you're calling for service every season, your system is on borrowed time. Not only do repeated AC repairs add up, but they also leave you vulnerable to inconvenient and expensive failures—often during a summer heatwave. 

You should also pay attention to comfort levels. Is your home cooling unevenly? Do you have hot spots, or does your system run all day without hitting the target temperature? These are clues that your air conditioner may be too small, too old or simply too worn out to perform properly. Our technicians can perform a load calculation to determine whether your current unit is the right fit—or if it’s time to consider something more efficient. 

Noise can also be telling. Grinding, rattling or loud fan sounds could mean internal parts are loose or worn out. While some noise issues can be fixed, others signal major wear and tear, particularly in aging units. That’s why Fonda’s always recommends scheduling a full system check before deciding on air conditioner installation or repair. 

We also consider your long-term plans. If you’re planning to sell your home soon, a new, high-efficiency system could be a great selling feature. But if you just need a few more summers out of your current setup, a quality AC repair may be the right call. That’s why we always give honest, expert recommendations tailored to your home, budget and goals. 

When Red Deer’s summer heat kicks in, you need cold air you can count on
