I have an older house with an old boiler system. I called J&L to have it inspected and to replace a few components. What I liked.
1. Jim was able to work with my work schedule and was always prompt.
2. VERY knowledgeable and professional
3. Easy to talk to
4. Did not try and sell me stuff that I did not need
5. Price was more than fair
Don't look anywhere else if you need HVAC work done.

Jim is the ONLY person I trust when it comes to HVAC. He is always quick to respond, HONEST & polite. As a woman, I am completely comfortable having him in my home and business. He takes the time to explain what he will do and has done, never pushing unnecessary work. His honesty and hard work have created a loyal client. Thanks Jim!

Used J & L based on recommendation of neighbors. I was blown away by the quality of their work and how reasonable they were. My neighbors have been using them for years and I believe we will also have a long relationship with J & L. I have already sent him to my relatives house to take care of them also.

I do not recommend J&L Mechanical at all. Very limited knowledge of his field and some questionable business practices. Claimed work we requested wouldn't be up to code, sold us on a much more expensive method, and yet failed to pull a permit for extensive work we contracted with him to do even though quoted price included the cost of the permit. Later, when we had trouble with the work, he told us that any further problems would have to be handled through the manufacturers.

J and L 's craftmanship was A-1. They removed my current system which was not working and replaced with a new more efficient furnace. The duct work and everything they had to do was really neat and professional. Through out the process I had many questions, all the workers took the time to explain everything that I asked in easy to understand terms. These guys are trustworthy, dependable, knowledgeable, professional, and do a great Job. I would recommend to anyone.

Very overpriced service and repair call on a pool heater. He was very proud of the little receipt machine in his oversized truck. He charged a $25 fuel surcharge for a total bill of $254 for a minor repair that didn't last. I found another company with much more reasonable fees.
