The project

About This Project

After a serious basement flood, the homeowners needed a full mechanical assessment—not an automatic replacement recommendation. The supplied project film documents water-damaged air handlers that could not remain in service, a repairable five-year-old Viessmann boiler, aging R-22 cooling equipment, and a failed pressure-reducing valve. Grove Mechanical retained and repaired the existing boiler where the narrated project evidence showed it could be safely returned to operation, then built the replacement scope around two new hydronic fan coils, cold-climate Lennox side-discharge heat pumps, updated pressure reduction, a Wi-Fi water shutoff with floor sensor, and a smart-thermostat handover. Customer location details are withheld.

After

Challenges We Solved

1Flood-related equipment damage

The project film records roughly two feet of basement water after the homeowners returned from vacation. The two affected air handlers were condemned, with seized blower motors and damaged circuit boards described in the walkthrough.

2Avoiding an unnecessary boiler replacement

Rather than treating the flood as a reason to replace every component, Grove assessed the existing Viessmann boiler and documented a repair-first solution for this specific project.

3Building prevention into the new scope

Alongside heating and cooling upgrades, Grove replaced the failed pressure-reducing valve and added a Wi-Fi water shutoff with floor sensor to support faster protection during a future leak event.

The Result

The project film documents a whole-home mechanical recovery: a retained and repaired Viessmann boiler, two new hydronic fan coils, Lennox side-discharge cold-climate heat pumps, replacement of aging R-22 cooling equipment, updated pressure reduction, Wi-Fi leak protection, and smart-thermostat setup. The story is a project-specific example of Grove’s repair-first, full-system approach—not a universal price or performance promise.

Frequently Asked Questions

What happened to the HVAC system after the flood?

The supplied project film explains that floodwater damaged both air handlers, including seized blower motors and failed circuit boards. Grove performed a diagnostic assessment to identify what could be safely retained and what needed replacement.

Why was the boiler repaired instead of replaced?

On this project, Grove’s assessment found a repair path for the existing Viessmann boiler. The decision was project-specific and based on the equipment condition, site findings, safety, and the overall system plan; every flooded system needs its own assessment.

What did the heat-pump upgrade include?

The documented scope included two new hydronic fan coils and Lennox side-discharge cold-climate heat pumps, replacing the older R-22 cooling equipment shown in the project film. Equipment selection and design should always be matched to the home and existing mechanical system.

How does a Wi-Fi water shutoff help protect a home?

The water shutoff shown in this project uses a floor sensor and can automatically close the water supply when it detects an emergency. It is one layer of protection that can be particularly useful for homeowners who travel, but it does not replace regular maintenance or insurance coverage.

Equipment Used
