In Ottawa, a lot of ductless systems are installed for heating first — and when they’re working properly, they’re efficient and comfortable. When they aren’t, you’ll notice it fast: weak heat, constant running, icing, water leaks, loud operation, or error codes.
Peak Comfort HVAC provides ductless heat pump repair across Ottawa and surrounding areas. We diagnose the system properly: indoor and outdoor sensors, communication wiring, defrost behavior, refrigerant performance, airflow, and drainage. We also check setup items that impact heating comfort — like control settings, fan operation, and whether the system is actually delivering the heat it should.
We don’t treat ductless like a mystery box. We test, confirm, repair, and verify — so you get reliable heat again.

• Heating-performance checks: We verify operation in heating mode: not just “it turns on.”
• Defrost and sensor diagnosis: Ottawa winters expose weak defrost/sensor issues fast. We confirm what the unit is doing and why.
• No band-aid fixes: If refrigerant is low, we don’t treat a top-up as the solution: we diagnose the reason.
• Clear explanations: Error codes and ductless behavior can be confusing. We explain what’s happening in plain English.
• Clean, careful work: Proper drain routing, sealed penetrations, tidy wiring, and a clean finish.
What to expect:
Step 1 — Diagnose: Confirm the root cause with readings and testing.
Step 2 — Explain & quote: Clear options and pricing before work starts.
Step 3 — Repair & verify: Repair, then verify stable heating and proper defrost operation.
