❄️ Masonville London Ontario — What We Know About These Homes
Masonville occupies north-central London, anchored by Masonville Place mall at Richmond Street and Fanshawe Park Road East. The neighbourhood developed from the late 1960s through the 1990s with a mix of executive detached homes, well-appointed two-storeys, and townhome complexes. It is one of London's higher-income areas with a strong base of long-term, engaged owner-occupants.
Masonville's AC systems are predominantly 1990s through early 2000s vintage — now 20–35 years old and well into the component failure zone. The most common Hawana calls in Masonville are capacitor and contactor failures on older Carrier and Trane units, refrigerant leaks from aging coils, and compressor failures in units approaching end of life. Some larger Masonville executive homes also have multi-zone HVAC with damper systems that can fail independently of the AC unit itself.
Masonville homeowners generally know their homes well and are specific about what they need. Hawana appreciates this — a clear symptom description speeds diagnosis, and Masonville customers tend to ask the right questions about repair vs. replacement decisions.

What Hawana finds most often when servicing Masonville AC systems — and what to watch for.
Aging 1990s Carrier and Trane Unit Failures
Masonville has a high concentration of 1990s-era Carrier and Trane central AC units now 25–35 years old. These units commonly fail via capacitor failure, contactor wear, refrigerant leaks at aging coil connections, and compressor overheating from restricted airflow. Hawana carries parts for all major 1990s Carrier and Trane models on every service truck.
⚠️ Watch thisMulti-Zone System Complexity
Some larger Masonville executive homes have multi-zone HVAC with zone dampers and multiple thermostats. When one zone stops cooling, it's often misdiagnosed as an AC failure when the actual cause is a failed zone damper or zone board. Hawana technicians diagnose the full system before recommending any repair — saving Masonville homeowners from unnecessary equipment replacement.
ℹ️ Good to knowRefrigerant Leaks from Aging Evaporator Coils
Masonville's 25–35 year old AC systems commonly develop pinhole leaks in the evaporator coil from formicary (formic acid) corrosion — accelerated by certain cleaning products used in renovated Masonville kitchens and bathrooms. Hawana performs leak detection on every low-refrigerant call and advises honestly on whether repair or coil replacement makes financial sense.

Check these before calling — some issues can be resolved without a service call.
Check the thermostat and filter
Confirm the thermostat is set to COOL, fan AUTO, temperature below current room temperature. Then pull the air filter — a clogged filter causes evaporator coil freeze-up, the most common cause of AC airflow failure. Replace if dirty and allow 30 minutes for the coil to thaw before restarting.
Check the electrical panel and disconnect
Find the AC breaker in your electrical panel — a double-pole 240V breaker. If tripped, reset once. Also check the AC disconnect box at the outdoor unit to confirm it's closed and the fuses inside are intact.
Check if the outdoor unit is running
Go outside and observe the condenser unit. You should see the fan spinning and feel warm air from the top. If the fan is not running but you can hear a humming sound, a failed capacitor is the most likely cause — the most common Masonville AC failure. Do not repeatedly try to restart it.

What Masonville London Ontario Customers Say
5.0 stars · 139 Google reviews · See all reviews ↗
“Our 1997 Carrier stopped cooling on the hottest August day. Hawana arrived within 90 minutes, diagnosed a failed capacitor, and had us running in under an hour. The technician also checked the refrigerant level and coil condition while he was there. Professional, thorough, completely fair on price.”
“Called Hawana for an AC tune-up before the summer on our Masonville home. Technician found a refrigerant leak at the evaporator coil connection — small enough that it hadn't affected performance yet, but would have failed mid-summer. Fixed and recharged. Highly recommend for any Masonville home with older equipment.”
