Andrew was phenomenal to have for my first experience with Thumbtack. Was glad to hear his knowledge with smart Thermostats and expertise in installing them. He was able to fit me in rather quickly and could not be happier with his service. Will definitely recommend to anyone seeking help upgrading your thermostat!

I hired this professional to install a new thermostat b/c my old one went blank. He showed up and we found I didn’t need a new thermostat after all! He was not pushy at all and was not upset that we decided not to replace it. Instead, he inspected my furnace and installed my new filter. Highly recommend!

Andrew installed an Ecobee thermostat for me. He was very professional, proficient, and let me know what he was doing during setup. I would highly recommend his services and wouldn’t hesitate to hire him again. Thank you!

I got a new Nest E thermostat that a friend installed. It started to short cycle my furnace. Andrew came out to help figure out the issue. And worked with me until he figured it out!

Installed a Smart Thermostat in our home. Was quick and efficient. What was great is that he took the time to be sure everything was working great! Went above and beyond!
