Satisfied Customers


Just wanted to thank you for the excellent work you did installing the York Furnace & AC unit in my home recently.  Your professionalism & Craftsmanship were greatly appreciated.  It’s nice to see someone who takes great pride in doing the best job possible.  I will be recommending  J&L Mechanical for any HVAC project big or small.

Best Regards,

I bought a new house in 2005.  The heat and cooling never really seemed to do the job in a timely fashion.  The HVAC company that installed it was useless to get answers, and they had horrible craftsmanship.  I saw a J and L Mechanical Services truck and decided to stop and talk to the person.  Since day one, J and L Mechanical has taken the time to talk and point out the inexperience of the other HVAC company.    J and L had great ideas for taking my existing system and making it efficient and work for my house.  The employees were all knowledgeable and trustworthy.  My system works great now.

J and L Mechanical is trustworthy, dependable, knowledgeable and does excellent work.   I would recommend to anyone.

You know the saying “I got a guy”! Well I’ve had a guy that beats all the other guys when it comes to heating and cooling. J and L Mechanical has been “My Guy” for over 20 years and I have recommended them to numerous friends and business associates. I have found them to be more knowledgeable and more reliable than any other Crown Point Heating and Air Conditioning Company.

I have had many heating contractors at my home over the years and J & L was the first to come out at a moments notice in the middle of the night and not rob me blind. He knew the problem within minutes. THANKS
