    I decided to give this small company a try, and I couldn’t believe how professional they were. Corey and Dave were extremely helpful from the initial estimate all the way through to the completed job. I highly recommend this company!

    Sentry installed a 6 ton Water Furnace that replaced a 3 ton and a 4 ton heat pump system in our home . Their duct work craftsmanship is incredible and their work is top notch. Professional and courteous - a must use if considering a Geo thermal system.Services: Heating system installation
