Heat Pump Repair Oakville - FAQs

Do you repair all heat pump brands in Oakville?

My heat pump stopped working in winter - can you help today?

Yes. We offer 24/7 emergency heat pump repair in Oakville with no overtime fees. For winter emergencies, we prioritize same-day dispatch. Call (416) 835-4775 any time.

Does my heat pump need annual maintenance in Oakville?

Yes. We recommend annual maintenance in spring (cooling prep) and fall (heating prep). Regular maintenance prevents breakdowns and maintains your warranty. Ask about our maintenance plan.

Why is my heat pump blowing cold air in winter in Oakville?

This is usually caused by a stuck reversing valve, low refrigerant, a failed defrost board, or the backup heat not engaging. Our technicians carry these parts and can resolve most causes in one visit.

Can you repair a heat pump that was installed by another company in Oakville?

Yes. We service heat pumps installed by any company. As long as your system is a recognized brand, our technicians can diagnose and repair it.

What is a heat pump reversing valve and how much does it cost to replace in Oakville?

The reversing valve is what allows a heat pump to switch between heating and cooling modes. Replacement typically costs $400-$700 in Oakville depending on the brand. We quote the exact price before starting.

My heat pump outdoor unit is iced over. Is that normal?

Some frost is normal during cold weather. A full ice buildup that doesn't clear during the defrost cycle indicates a refrigerant issue, a failed defrost board, or blocked airflow. Call us if the ice does not melt within 2 hours.

How long does a heat pump repair take in Oakville?

Most heat pump repairs are completed in 1-3 hours. Complex issues like compressor replacement may take longer. We give you a realistic timeframe when we quote the job.
