Air Conditioner Repair Mississauga: Should You Fix an R-22 AC Unit or Replace It?
The Problem: Old AC Unit Not Cooling Properly
You turn on your air conditioner, but the home still feels warm. The system may be running longer than usual, airflow seems weak, or the air isn’t as cold as before.
In many homes across Mississauga, this issue often comes from older air conditioning systems that use R-22 refrigerant (commonly known as Freon).
If your AC is more than 10-15 years old, there’s a high chance it uses R-22 and this is where the real problem begins.
What Is R-22 Refrigerant and Why Is It a Problem?
R-22 was widely used in residential air conditioning systems for decades. However, due to environmental concerns, it has been completely phased out in Canada.
What this means for homeowners:
- New R-22 refrigerant is no longer produced or imported
- Remaining supply is extremely limited and expensive
- Most HVAC companies avoid recharging R-22 systems
So if your AC is low on refrigerant, it’s not just a small repair anymore, it becomes a major decision.
Common Symptoms of an R-22 AC System Failing
If your system still uses R-22, you may notice:
- AC blowing warm or slightly cool air
- Ice buildup on refrigerant lines or evaporator coil
- Hissing sounds (possible refrigerant leak)
- Long cooling cycles and higher energy bills
- System constantly running without reaching set temperature
These are often signs that your unit is low on refrigerant or has a leak.
Why Repairing an R-22 AC Unit Is Usually Not Worth It
1. Refrigerant Is No Longer Available
If your system is low on R-22, topping it up is not a realistic long-term solution. Even if reclaimed refrigerant is available, it’s very costly and there’s no guarantee it will remain available.
2. Leaks Mean Bigger Problems
Refrigerant doesn’t just “run out.” If levels are low, there is a leak somewhere in the system. Fixing the leak and recharging an R-22 system can cost a significant amount and still doesn’t guarantee reliability.
3. Aging Components Will Continue to Fail
Even if you repair one issue, other parts like:
- Compressor
- Capacitor
- Contactor
- Fan motor
may fail shortly after. It becomes a cycle of repairs.
When Repair Might Still Make Sense
There are limited situations where repairing an R-22 AC unit is reasonable:
- Minor electrical issues (capacitor, relay, contactor)
- Quick, low cost fixes with no refrigerant involved
- Temporary solution if you’re planning replacement soon
Important: Even in these cases, the repair is usually short term. Most older systems will continue to develop new issues.
Real Scenario from Mississauga
A homeowner had an older AC unit that wasn’t cooling properly. After inspection, the system was found to be low on R-22 refrigerant due to a leak.
Instead of investing in an expensive repair with uncertain results, they chose to upgrade to a new system using modern refrigerant (R-410A).
Result:
- Lower energy bills
- Better cooling performance
- Peace of mind with warranty
The Better Solution: Upgrading to a New AC System
Modern air conditioners:
- Use environmentally friendly refrigerants (like R-410A)
- Are significantly more energy-efficient
- Provide better cooling and humidity control
- Come with manufacturer parts warranties (typically 10 years)
Replacing an old R-22 system is not just a repair decision, it’s an investment in long term comfort and reliability.
Our Recommendation (Honest Advice)
If your air conditioner:
- Uses R-22 refrigerant
- Has a refrigerant leak
- Is over 10–12 years old
It’s usually not worth investing in major repairs.
A small repair might get it running temporarily, but in most cases, replacement will save you money and stress over time.

Q & A: R-22 Air Conditioners
Q1: Can you still recharge an R-22 air conditioner?
In most cases, no. R-22 refrigerant is discontinued, and available supply is very limited and expensive.
Q2: Why is my R-22 AC low on refrigerant?
Refrigerant does not get used up. If it’s low, your system has a leak that needs repair.
Q3: Is it safe to keep using an R-22 AC unit?
Yes, if it’s still working properly. However, once a major issue occurs, repairs become impractical.
Q4: How do I know if my AC uses R-22?
Check the label on the outdoor unit. It will indicate the refrigerant type (R-22 or R-410A).
Q5: Should I repair or replace my old AC?
If the repair involves refrigerant or major components, replacement is usually the better long term choice.
