We contacted Westapro on a Saturday mid morning with an issue with our new Nest thermostat install. Due to crossed wires during our DIY install we had blown the furnace fuse and the ground wire in the thermostats was no longer receiving power not allowing us to complete our install. Sergei came the same afternoon, debugged the issue, replaced the blown fuse and completed the install of the new thermostat. Sergei was fast, efficient and price was reasonable. Thank you for the good work and we will hire you for our next project when it comes up !

Sergei showed up on time and got to the task right away. He was quite accurate with time estimate for fan installation in 3 bedrooms with new switch point and running new electric line via attic. We are happy with his work. He also cleared up all the debris and did great post work cleanup. He got all the tools and materials needed to do the job. I found him to be honest and hardworking professional.
