They were able to salvage my leaking mixing valve on my water heater and noticed that it only needed a new grommet. While they were at my house they also serviced my HVAC system and took the time to educate me on how to maintain the mechanical systems in my house. Overall their tech was professional, tidy, and friendly. I was impressed with the quality of work and I felt they did a good job.

I am very disappointed with my experience with Leaps & Bounds. After purchasing a brand new HVAC…read moresystem, I expected a smooth installation and a working unit at the end of the day. Instead, the installers were here all day and still had issues with the brand new unit, leaving me without AC on a very hot day. It made being in the house very uncomfortable. Although the installers were nice, that was the only good part of this experience. The company offered to pay for a hotel, but because of other responsibilities, it was not a practical solution. What made matters worse was the lack of communication afterward. I was told technicians would arrive at 10:00 a.m. the next day to troubleshoot the problem, and I made sure to be home. By 10:45 a.m., I still had not heard from anyone. No call, no update, nothing, until I reached out to them. The new technicians finally arrived at 11:45 a.m. For the amount of money a new HVAC system costs, this level of inconvenience and poor communication is unacceptable. Nice technicians do not make up for a brand new system not working and the lack of respect for a customer's time.
