    Condensate pump was never connected causing damage to my kitchen
    Will S.

    In July 2023, NETR installed a $39,000 LG Whole House Heat Pump system in my home (3 indoor units, attic ductwork, outdoor unit, and a branch box). Since then, I've experienced numerous installation and equipment issues--some posing real safety risks. I found out NETR never pulled any permits for the work. Despite confirming their mistake and promising to fix it, as of July 2025 the project still lacks proper permits and inspections. My town Building Department has followed up several times requesting missing info and payment--NETR refuses to respond to myself or the town, and I am left chasing them. I've had to involve third-party contractors and LG's support team just to get basic issues resolved. NETR has been out to my home at least 10 times since system install, and shown no accountability for any of the downtime, frustration, and safety issues related to this expensive system. If you're considering NETR--do your homework. I regret trusting them with such an expensive and critical system. Expect installation issues, repeated service calls, and premature equipment failures.

    Final hyper heat product installed on three floors.

And this spring they have yet to answer their phone or return any calls.

I contracted MVP to install a Mitsubishi HVAC system in 2024. The list of critical failures during installation is too long to list here, and in fact one of their technicians (the only one who actually fixed the critical issues) was fired for suggesting that I seek recompense for their haphazard installation. But the most alarming concern is the obvious avoidance and deceit by the ownership. I paid for seven MHK-2 remote thermostats, totaling nearly $3k. Those thermostats were never provided, and no refund was ever issued. Jonathan nor anyone at MVP has responded to multiple calls and requests to provide the hardware. Only ghosting. I hate leaving negative reviews but this is beyond unprofessional. It's criminal.
