Prompt and professional technicians. Our furnace was acting up so we called J &J. Evan found the problem(s), explained to us what needed to be done before we told him to go ahead with the work. Our furnace is now working properly and now we have peace of mind! Our experience with J & J is the best we’ve encountered in a very long time. From the first call to the professional work done. J & J is now our HVAC guys!
