AC repair costs in Ontario typically range from $150 to $600 depending on the problem and parts needed. Common repairs like capacitor replacements are on the lower end, while compressor or refrigerant work costs more. Stan’s Heating always provides a free estimate so you know the cost before we start.

The most common causes are low refrigerant (often from a leak), a dirty or frozen evaporator coil, a failing compressor, or a clogged air filter. Some of these can be checked yourself (like the filter), but refrigerant and coil issues require a licensed technician. Call Stan’s Heating and we’ll diagnose it fast.

Yes. We offer same-day AC repair for most service calls in Ontario, OR. For true emergencies, we’re available 24 hours a day, 7 days a week. Call (541) 889-3987 to speak with our team and get a technician dispatched.

If your AC is under 10 years old and the repair cost is less than half the price of a new system, repair usually makes sense. If it’s over 12–15 years old, requires frequent repairs, or uses R-22 refrigerant (which is no longer manufactured), replacement is often the better value. Our technicians will give you an honest recommendation.
