What sets us apart
Single source for all trades
Most NH HVAC contractors do not also do plumbing and electrical, and most plumbers do not handle generators or EV chargers. Our in-house teams cover the full residential mechanical scope, which means one phone call, one trusted relationship, one company accountable for the whole project.
Licensed in-house technicians
Our installers, service technicians, plumbers, and electricians are licensed and credentialed in New Hampshire. We do not subcontract trade work to outside crews.
Permits and inspections handled
Every job that requires permits gets them pulled and inspected, no exceptions. Unpermitted work creates problems later with home sales, insurance claims, and warranty service.
Honest pricing
Transparent pricing before work begins. No surprises at completion. We will tell you when repair is the right answer and when replacement is the better long-term value.
Four generations of NH experience
The company that started in 1928 has seen every heating technology, fuel transition, and code change in the past century. That experience shows up in installation decisions you may not even notice.
