Heat Pump Repair Scarborough - 24/7 Emergency Service

Exposed Scarborough sites, especially toward the Bluffs, get wind-driven snow that packs against the coil. The unit cannot breathe, head pressure climbs and it locks out. Siting and stand height fix this permanently.

A heat pump runs all winter and needs clearance beneath it for defrost meltwater and for air. Units set on a slab at grade, which is fine for a summer-only air conditioner, ice into a solid block. We raise them onto a proper winter stand.

Post-war Scarborough lots often put the condenser in a narrow fenced run. The unit then recirculates its own discharge air instead of drawing fresh, which looks exactly like low refrigerant on a gauge.

Defrost water needs somewhere to go. Without a gravel bed or a raised stand it pools, refreezes and grows up into the fins.

We test the auxiliary stage and the changeover setpoint before touching refrigerant. Dead backup heat is a far more common cause than a failed compressor.

Thermostat placement, overcharge or an electrical fault. In a back-split the thermostat is often on the landing, which satisfies early and cycles the unit hard.

Loose panels and guard screws on an exposed site. Cheap to fix, and worth fixing before vibration reaches the line set.

Usually a pressure fault from blocked airflow rather than a component failure. We clear, verify and then look for the cause.
