Our house was built in 2001 and we have used many local services for the yearly service. Today was our first service with John Lock Services and the service was the absolute best service to date. Thorough, professional and above all honest.

This place is downright awful. I called yesterday because my heater was giving off an awful toxic smell. So the guy gets here and literally accidently breaks a fan to our inducer and claims that was the problem. Well as soon as he left our heater was not working at all and had to sleep with NO HEAT. I was not calling back because of the lack I seen. So I called another place today had them come fix it and it turned out to be my motor run capacitor and alot of collected dust in a vent. Not saying my furnace isn't old and could use a new one but what place would leave you without heat... paid 250 for fix today and paid john lock 100 bucks to do nothing but break my inducer. Also called and complained today and THE OWNER told me I was dumb and didn't know anything about a heater.

Thanks to the Gentleman who put in my new furnace today. It is nice and toasty warm and he was awesome! He even shoveled my porch for me and everything was taken care of just as I got home. He explained to me how it works and even offered up some good suggestions when I mentioned my nephew is just starting to toddle. Your lucky to have such a good guy on your team! Thank you so much!

It isn't commonplace to find a service company that doesn't rip you off. This is one of them! Our furnace started making a very scary sound and stopped working. Jerry found it to only be a nut that had worked it's way off! Any other company would have charged us $600 for a new unit. He cleaned our furnace (found out that we had filter in wrong way) and noted on our furnace the correct way to install filters in the future. We would never use anyone else!!
