Professional presentation, explanations, installation, and follow - up assistance with warranty registration. New furnace is only a week old but seems to be running well.

All representatives from John Lock {Chris, Paul, and Mike} were extremely professional, knowledgeable, and courteous. There was a third installer that was equally as nice, but I failed to get his name. The installation crew cleaned-up after themselves on both days and left their work area impeccable. Chris was punctual for the estimate appointment and provided me with plenty of information. I've been a homeowner for 14 years and this was the best company/crew I have ever had the pleasure of meeting. I highly recommend John Lock Air Conditioning & Heating to anyone.

Another great job. Second air conditioning system they installed for me. Prompt, professional, and a competative price. They also do all my furnace repair work in a very timely matter. I recommend John Lock Air and Heating.

No one likes to have to purchase a new furnace and air conditioner but working with Chris *****took some of the pain out of the process. He explained everything and there was definitely ?no push? involved. Everything went exactly as he said it would. The installation team was punctual, went over both units and were very helpful with questions. Installation is complete and we couldn?t be happier.

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 com...  more>>

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! ���
