Pricing was transparent. Not the cheapest option, but the Rinnai RX180 feels like a quality upgrade.
Laura Bennett –
Simple install and steady hot water. No complaints so far.
Omar Hassan –
Unit performs well, but make sure your gas line is adequate. Install team explained this clearly.
Hannah Wilson –
Good experience overall. Slight wait for parts, but Jimmy HVAC kept us informed.
Kevin Liu –
Service was fast once booked. Install finished earlier than expected.
Emily Fraser –
We’ve had the Rinnai RX180 for three months now. No temperature swings and it handles two showers at once fine.
Robert Gagnon –
Works well, but the initial setup explanation felt rushed. Unit itself is doing its job.
Melissa Wong –
Installers were respectful and cleaned up after. Price was reasonable for a tankless system.

Switched to the Rinnai RX180 for energy savings. Too early to tell on bills, but performance is solid.

Hot water never runs out now. Took a couple days to get the appointment, but install itself was smooth.
Andrew Collins –
Good service and no pressure upselling. Took about half a day to install.

immy HVAC handled the install cleanly. The Rinnai RX180 is much quieter than our old tank.

Water heats fast, but there’s a slight delay on the far bathroom. Overall still happy with the unit.

Installation team was on time and explained how the system works. Pricing was fair compared to other quotes we got.
