## The honest read

CNM Heating Cooling Piping installs and services heating and cooling systems and delivers heating oil, and it holds 5 stars from 193 Google ratings. Its website describes on-time oil delivery to homes and businesses, with automatic delivery offered without contracts.

A recent Google customer replacing an old Sanyo mini-split system said a 4-man crew arrived early on the scheduled day and finished the new Fujitsu Airstage install the same day, laying down runways and removing their shoes inside. A recent customer said Cody and his team installed a few split units in a barn and got the work done on the day he said he would.

A 2026 customer who switched their oil delivery to CNM wrote that the delivery was timely and they had not run out of oil, and that CNM also replaced their forced air system. A 2025 customer said CNM replaced their boiler. A 2025 customer said CNM switched out a 55-plus-year-old oil tank and some parts on their furnace. A 2024 customer said CNM found that a part a previous company had replaced on their oil furnace was not attached properly, fixed it and adjusted the flame, then put in a new oil line the next week.

A 2026 Reddit commenter on r/Connecticut wrote that they had used CNM in Mansfield.

**Strengths:**
- Same-day mini-split install — a recent customer said a 4-man crew finished in a day
- Timely oil delivery — a 2026 customer said they had not run out of oil
- Furnace repair — a 2024 customer said a loose part was found and fixed
- Barn split units — a recent customer said work was done on the promised day
