Your air conditioner is one of the most important systems in your home. It keeps you comfortable during the hot summer months and represents a major investment in your property. So when it starts acting up, you may be asking yourself: Should I repair or replace my air conditioner? Here’s how to make the right decision.
When It Makes Sense to Repair Your Air Conditioner
In many cases, repairing your AC unit is the more affordable option. Consider repair if:
- The repair costs are under $5,000
- The system is less than 10 years old
- You have a valid warranty that covers parts or labour
- You are enrolled in a maintenance plan
If your system has been performing well overall and just needs a minor fix, a repair can extend its life and save you money in the short term.
When You Should Consider Replacing Your AC Unit
There are situations where replacement is not only the better option but the more economical one over time. Consider replacement if:
- Your unit is more than 10-15 years old
- Repair estimates are over $5,000
- Your system frequently breaks down
- You want to improve efficiency or take advantage of tax rebates
An older, unreliable system that needs constant attention can cost more in repairs and energy bills than a new unit would over time. Replacing it can offer peace of mind and long-term savings.
How Long Does an Air Conditioner Typically Last?
Most air conditioners last between 10 and 20 years. Proper maintenance, such as annual tune-ups and regular filter changes, can help extend that lifespan.
As a general rule:
- If your AC is under 10 years old and still running well, repair is usually the best option
- If it’s over 10 years old, out of warranty, and requiring more frequent repairs, replacement may be more cost-effective
When It’s Time to Replace Your Air Conditioner
There are a few clear signs that it may be time to call a professional and start planning for a replacement:
1. Outdated Refrigerant
If your system uses R-22 refrigerant, repairs will be more costly and environmentally unfriendly. Modern systems use R-410A, which is safer and more efficient.
2. Increasing Energy Bills
An older or poorly sized unit can use far more electricity than a newer, efficient model. Replacing your AC could significantly lower monthly energy costs.
3. Warranty Expired or Invalid
If your warranty has lapsed and your system needs major repairs, replacement might be the better option, especially when you consider the cost of future breakdowns.
4. Too Small for the Space
Undersized systems will struggle to cool your home, run constantly, and wear out faster. Upgrading to a properly sized unit will improve comfort and efficiency.
5. Access to Incentives
Many homeowners qualify for rebates, tax credits, or local incentives when replacing an old AC with a high-efficiency model. These can significantly reduce the upfront cost.
6. New Technology
Smart thermostats, variable-speed motors, and improved filtration are just a few of the advancements in modern HVAC systems. Replacing your old unit gives you access to better technology and performance.
