  • when it was hot so was my house

I have a hard time believing any of their workers are trained or certified. That might be a good thing to find out next time their called for service. i had J & J out to replace my "old and inefficient" air conditioning system out this summer with a newer york system. After about two weeks of complaints from me did they finally get the problems right (while blaming it on their "good house keeping awarded equipment." At least in the long run my house was cooling ok. Very frustrating. I feel if you call yourself "factory trained" you sure better be it.

Customer Testimonials

This company is awesome. Great prices and amazing customer service. I called and they were able to come out the same day. I would recommend them to everyone. I love small businesses that treat you like family unlike the big HVAC in the area that are dishonest & overpriced.

I highly recommend J&J to anyone in the area. They were able to come out right away and fix my heater the first time at an affordable price. Great service and friendly people!

I am very pleased and happy I called J & J Heating & Air. I called several companies and they were the only ones that could come out the same day. My unit was making a funny noisy. The service tech Mike was professional, figured out the problem and explained to me the need for regular maintenance. I was expected a large bill and I was surprised on how reasonable the bill was. I even signed up for their yearly maintenance program. I will be a customer for life.

Very prompt professional and knowledgable service and repair. Have used J&J Heating and Air more than once and they have always been prompt, knowledgable, honest, and reliable. I am a life long customer!

Jason and his team were fabulous:
1) Super timely - they got our job in less than a week end-to-end, including permits!
2) Excellent quality - they provide top-of-the-line gear (Mitsubishi) at excellent rates with a super clean installation of our multi-room ductless system.
3) Extremely knowledgeable - they were able to handle a few tricky issues with regards to optimizing the system for our modest power availability and substantial space for heating/cooling.

They have really good service, owners are very nice and friendly. They won't over charge you and will let you know exactly what needs to be done. They fixed all of our duct work in our house and it is 100% better. I would recommend them to anyone.

Air conditioner quit cooling in the middle of the last heat wave. Always hard to get service when everyone is so busy, but Jason came out right away, diagnosed the problem and returned in a couple hours with the part. Working great now. The prices are also great too, since we had the same part replaced 3 years ago with a different company for much more.
