Common Daikin Rooftop Unit Problems
Daikin rooftop units are growing fast on GTA roofs, especially where owners are chasing efficiency or electrification targets. The calls we see most are Daikin Rebel inverter faults, Daikin Maverick service on larger retail and office units, and owners planning a heat pump RTU conversion who want straight answers on cost and winter performance.
Inverter-driven units are different from fixed-speed RTUs. An inverter compressor fault can come from the drive board, power quality, sensors or the compressor itself. We read the drive's diagnostic history and test before replacing anything.

Heat Pump RTU Conversions in Toronto
Converting a gas-fired RTU to a heat pump RTU cuts on-site emissions and can lower operating costs depending on rates. The key questions are winter capacity and backup heat. We size the unit for the actual load, plan backup heat for the coldest days, and file Enbridge HER+ and Save on Energy where they apply.
| Gas/electric RTU | Heat pump RTU | |
|---|---|---|
| Heating source | Gas burner | Compressor (with backup) |
| On-site emissions | Higher | Lower |
| Incentives | Save on Energy on efficiency | Enbridge HER+ + Save on Energy |
| Upfront cost | Lower | Higher before incentives |
