We just had JNL install a new American Standard furnace in our home. About two years ago, we had them replace our A/C unit. Over the past 30 years, they have installed 3 complete furnace and A/C systems for us at three different homes, in addition to doing a full system at my son's townhouse. Every time we have had permit inspections, the inspectors always comment about the great quality workmanship performed by JNL. We also have JNL perform annual maintenance on our equipment which is very important. We rarely require any servicing beyond that.
I actually looked back at a review I did three years ago, and all the same comments still apply: Great workmanship, highly responsive, very professional, extremely fair pricing - just an outstanding company to do business with. They take time to answer all your questions, they don't try to sell you things you don't need, and they back their work. I've referred JNL to a lot of people over the years. People ask "do you get competitive quotes for your projects?" For most big ticket jobs around the house, my answer is yes. But not when it comes to HVAC. We only call JNL.
You'll find most of the technicians at JNL have been there a long time, and I think that says a lot about the company, its values, and how they do business. We are grateful for the exceptional service they have provided over the past three decades. If you need HVAC work, I highly recommend giving JNL a call.
