When your dad calls and says "our oil tank is leaking", you go replace their tanks. Even if its 2 hours each way. We swapped out the old steel tank for a tandem Roth tank setup. I may not have always been the best behaved kid growing up, but I'm slowly making up for it.

When you know what you like, you stick with it. Mike loved his NTI and decided to upgrade his to a newer model before it would be obsolete. A new TRX-150S2 150k btu combi was installed with new mechanicals and piping floor up. Everyone should plan ahead like Mike.

Transitioning from oil to propane, we installed a new NTI heat and hot water boiler for enhanced efficiency.

Another commercial rooftop swap. In classic New England "snow one day, sun the next" form, we braved wind, sleet, and snow while we swapped out, and sun the next day. Wilcox Crane Service did their thing and got us up in the air. Employees are happy to have working systems after they went all winter with only 3 of 7 units operating.
