I told a neighbor last year to give him a call when her home heater failed last winter. She came back the next day with a bottle of wine to thank me. The first company quoted $12K for a new system. Mario's team identified the problem and fixed it for under $300. That's character you don't see much anymore. He's fair, honest and his folks are diligent workers.

Mario installed a mini-split as part of a recent addition we had done. The unit did not…read moreeffectively heat or cool from the very beginning. Initially we thought it was our general contractor that was the problem in getting it addressed. When we reached out directly, Mario twice scheduled and then no-showed. When we reached out again, his office delivered the message that he was too busy servicing contract clients. We had to hire another contractor and found the original install was improper causing a leak that eventually completely drained the system. On top of it, the brand turns out to be a low budget unit. The project was not low budget and neither the GC or Mario ever asked us whether we wanted a higher quality unit.

Their quote was a good price and they even found a better plan for the install that cost us less money. The install was great; the township inspector actually said it was one of the cleaner installs he'd seen. We love our new heat pump and everything is working great. If we'd stopped there, this would be a five star review. However, they still needed to fix a couple of things, remove our old oil tank and give us the purchase information for the warranty on the system. At that point, all communication stopped. They did not respond to phone calls or texts for several months until, on a hunch, I called them from a different number. One of the owners actually picked up, PRETENDED TO HAVE PHONE PROBLEMS, and hung up on me. At that point, we hired a lawyer. It took more time, but eventually they did make good on their promises. And, to be fair, they didn't ask for the remaining money we owed them but we had to pay the lawyer so financially it was a wash for us. To sum up: install-fabulous, aftercare-absolutely terrible. As it is, I would not recommend Seal the Deal unless they get someone else doing the scheduling.
