Google Review by Leonid: “J & K Air Conditioning & Heating services my AC/heating system for the last 10 years or so. Very professional, they come the same or the next day (depending on the urgency) and offer quality service at reasonable prices. They just replaced my AC/heating system with the new one, and all was done within a week of the first contact, offered detailed advice and help with energy rebates. All interactions were easy and pleasant. Highly recommend this company for all cooling-heating problems.”
