  • What Our Customers Say:

  • "When I asked for an estimate and the various heating options we had to replace our old boiler I felt that Haller was very impartial and fair in their advice. The estimate came in a bit higher than the other estimates I got, we were able to make a couple adjustments to make that more palatable, but mainly I chose Haller because of the excellent reports on Angie's List. I am very happy that we chose Haller. The job went very well from start to finish and was very professionally done. I felt they did an excellent job as the furnace room where the installation took place was very small and cramped quarters, yet the job looks beautiful and actually saved some space. Several experienced individuals have looked at the job and commented on the excellent craftsmanship. The system works very well, seems to be efficient, keeps the house warm easily and we have plenty of hot water. Very happy with the quality of work done."
