The Problem: 16-year-old central AC system in Cape-style home had a leak and needed an overhaul to keep the family comfortable all year long.
The Solution: N.E.T.R., Inc. installed a new Carrier 16 SEER high-efficiency system to help save the family money on their monthly bills.






Winchester, MA, is an excellent place to live, especially for those who work in or around Boston. It’s just a short drive from the main city but offers that quiet, suburban life that many families enjoy.
When the family contacted N.E.T.R., Inc. with their problem, Mike Herrick took up the project. He met with the homeowners to tour the house and take a look at the existing central air system. While he was assessing what the owners would need to be replaced, Mike noticed that the 4-ton central air R22 system had a leak. He informed the homeowners of the leak and offered his proposal for the new system.
Before Mike’s team could start installing the central air conditioning system, they had to remove the parts of the existing system that were rundown. First, the team had to ensure all remaining R22 from the old AC system was recovered and disposed of properly. Additionally, the refrigerant piping for the old system had to be removed because of the leaks. N.E.T.R., Inc. also removed the existing coil from above the furnace and disconnected all the low voltage electrical wiring. All of these things must be disposed of following EPA guidelines, so N.E.T.R., Inc. knew that proper removal and disposal was important.
