We had an issue with the furnace thermostat -it was not heating properly. So we contacted this repair service to get it fixed or replaced, if necessary, as soon as possible, since they have this emergency option. And they came quickly! The technician found that we needed to replace the thermostat, it was the only way out. Plus, the price was affordable.

We were looking for the best price in the first place and this company could offer that. Here we found a complete package - we bought a great Bosch model and ordered its installation, which was cheaper all together. In addition, they helped us apply for a government rebate.The heat pump installation itself went just fine, no complaints.
We will deliver a Boiler Natural gas to any of these cities
