Clinton Township wraps around the separate Town of Clinton and takes in Annandale, the Round Valley and Spruce Run recreation areas, and the interchanges where I-78 crosses Route 31. Its housing runs from old farmhouses on the back roads to large subdivisions built from the 1980s onward, so on any given week we are servicing both original cast iron and twenty-year-old high-efficiency equipment. That range is exactly why we send techs who work on old and new systems every day.

What We See in Clinton Township Homes & Buildings
- The subdivision housing built from the 1980s through the early 2000s is now hitting the age where furnaces, condensers and water heaters all come due within a few years of each other.
- Developed sections are served by public utilities while properties on the outlying roads are on wells and septic — the two call for different advice on filtration, drain care and sump discharge.
- Full basements are the norm in the newer neighborhoods, which makes them good candidates for sump pumps, battery backup and clean mechanical-room layouts.
- Note that Clinton Township and the Town of Clinton are separate municipalities, so permits and inspections go through whichever one your address actually sits in.
Sections of Clinton Township we serve include Annandale, Beaver Brook, along with every other part of the township.

Clinton Township Plumbing & HVAC FAQs
Are you talking about Clinton Township or the Town of Clinton?
Both are in our service area, but they are two different municipalities. Tell us your street address when you call and we will make sure the permit and inspection go through the right office.
Our furnace and AC are both original to a 1990s house. Repair or replace?
It depends on the failure and the condition of the rest of the system. We give you the repair cost and the replacement cost side by side, and if a changeout makes sense our engineers size the new equipment to the house rather than just matching the old label.
Who handles the township paperwork on a boiler or water heater changeout?
That is on us. Changeouts like that require a permit here, so we prepare the application, install to code, and meet the township inspector ourselves when the sign-off is scheduled.
