A recent customer says the company came out quickly for an issue with their geothermal system, fixed it fast, and charged far less than they had feared. A recent customer says Marc showed up when expected, serviced their air conditioner and furnace, and left everything spotless.

A 2026 customer said Marc diagnosed the issue, cleaned out their AC unit and got their heat running again.

A 2025 customer said Marc repaired a large heat pump, a complex job with a major part needing replacement. A 2025 customer said that after another contractor's annual maintenance left a boiler leaking and no hot water, Marc came out within a few hours of the call and restored the system. A 2025 customer said Mark replaced a hot water heater at their home in Keene after two other plumbers could not take the job, coming out the next day.

**Strengths:**
