Quick Troubleshooting: What to Check Before You Call
| Check | What to Do |
|---|---|
| Air filter | If it’s grey or clogged, replace it. A dirty filter restricts airflow and can cause your system to stop cooling. |
| Thermostat | Make sure it’s set to “cool” and the temperature is set below room temperature. Check that the batteries aren’t dead. |
| Circuit breaker | Check your electrical panel. If the AC breaker has tripped, flip it back. If it trips again, stop and call for repair. |
| Outdoor unit | Make sure the condenser has at least two feet of clearance. Remove any grass, leaves, or debris blocking the unit. |
| Vents and registers | Walk through your home and make sure all supply vents are open and unblocked by furniture or curtains. |

How to troubleshoot your Air Conditioner
What Our Customers Are Saying about Us In:
Toronto
What a great experience with Reliance! My air conditioner stopped working this past Saturday and wit h the hot temperatures in Toronto, being in the house this weekend was very unpleasant. Thankfully I got a visit from Sam today and he did a great job! He was very attentive and fixed all the issues with the equipment. Thank you again Sam! I can sleep better now!
Amir & Adam did a fantastic job installing our new furnace, A/C, and humidifier. They were polite, p rofessional, and explained in detail the functions and benefits of each product. Thank you for the wonderful service!
Called yesterday to get a quote for a new air conditioner. I was given an appointment for this after noon, not only was salesman on time but he actually called ahead and asked if it would be ok if he came early. He was here a couple of hours early, and were all my questions and arranged for instillation for tomorrow.
Is It Worth Repairing My Old AC?
If your system is under 10 years old and this is the first major repair, a fix is usually the right call. If the repair cost exceeds 50% of a new unit, or the system is 15 years or older, replacement is usually the better long-term investment.
| Factor | Consider Repair | Consider Replacement |
|---|---|---|
| System age | Under 10 years | 15 years or older |
| Repair cost | Less than 50% of a new system | More than 50% of a new system |
| Efficiency (SEER2) | Rated 13.4 or higher | Below current minimum standards |
| Refrigerant type | R-410A (Puron) | R-22 (no longer produced in Canada) |
| Repair frequency | First major repair | Multiple repairs in the past 2 years |
A Reliance technician can walk you through your options and help you compare the cost of a repair against a new system. Not ready to buy? Explore rental options with repairs included.
