Aaron just gave our boiler a little preventative maintenance service, and I was thoroughly impressed. Not only is their service professional and prices reasonable, but they were honest about what needed to be done and didn't try to up-sell us on things we didn't need.

Just a follow up note to a review and our service from 3 years ago -- the Armstrong furnace that Aaron and the crew installed is still running perfectly -- not a single complaint and I am so grateful for the quick and professional service they provided us. I thought about it just the other day when Spring finally hit and the furnace gave over to the air conditioner that Aaron has inspected for us (thanks to the programmable thermostat they provided). Give them a call and get ready for an amazing upgrade to your system at a fantastic price!

Finishline's customer service is outstanding. They answered all my questions and took the time to explain exactly what I needed done. Aaron installed my new furnace and warmed my family back up on very short notice. We greatly appreciate everything they did for us. We would highly recommend them!
