6 reviews for Navien NCB-240/110H Combi-Boiler For Homes 2000-2400 Sq.Ft

  1. David Chen

    Performance has been solid, but communication before installation could have been better. Installation itself was done properly.

  2. Karen O’Brien

    Hot water is consistent even with two showers running. Jimmy HVAC’s install team was polite and efficient.

  3. Samir Patel

    The Navien NCB-240/110H is a good fit for our two-storey home. Pricing wasn’t cheap, but the quality of work was good.

  4. Lucas Tremblay

    Quiet operation and steady heating. Service was quick once the appointment was confirmed.

  5. Natalie Fischer

    No problems with the unit so far, but install ran longer than expected. Overall experience was average.

  6. Omar Siddiqui

    Jimmy HVAC installed the combi boiler in one day. Heat recovery is quick and hot water supply has been reliable.
