J & K

J & K Air Conditioning & Heating holds a 4.8-star average across 18 customer reviews, indicating consistent service quality in the Baltimore metro area. Based in Gaithersburg, this family owned and operated company has been serving Montgomery County MD since 1981. Their service coverage extends across multiple communities including Germantown, Rockville, Silver Spring, Bethesda, and surrounding neighborhoods in Maryland, plus select areas of Virginia.

The contractor distinguishes itself as both a Carrier and Lennox dealer, offering new system installations alongside comprehensive repairs for all major HVAC brands. They maintain specialization in humidifier and air cleaner servicing, and provide preventive service contracts designed to keep existing equipment performing optimally. Current promotions include rebates up to $1,800 on select Lennox systems with financing options for qualified buyers.

Customer feedback highlights specific technicians Kyle, Tony, and Joey handling complex installations and challenging diagnostics. One reviewer recounting a years-long battle with a faulty AC system noted J & K ultimately solved the problem that two previous contractors could not resolve. Another mentioned the team arriving on schedule, respecting the homeowner's property, and providing expert answers to technical questions during a furnace replacement.
