We have been using J&K air conditioning and heating for over thirty years. We have always been extremely satisfied with their service, cost, responsiveness and recommended products. The routine maintenance contracts that we purchase annually give us peace of mind and insure the timely and thorough maintenance of our heating and A/C units. We unconditionally recommend J&K.

I'd give them an "A" overall. There wasn't that much to it, they checked my heat pump to make sure it was working properly, It took one guy about 20 minutes. I would use them again. I've been using them for many years.

They have done my air conditioning and heating for twenty years. They are "A" everytime, that's why I've been using them so long. They are awesome. I have a service contract through them. I will always use them. As long as they are around I'm using them.
Description of Work: They came out last month or the month before. I was having issues with my air conditioning and I have their service contract. They came right out and took care of me. I think it was under $100 for the service they did.

I am 100% satisfied with the service I received from J & K Airconditioning. Scheduling was easy, and they called ahead of time to remind me and confirm the appointment. I had a 3-4 hour time frame during which they would arrive and they were at my house and ready to work within the 1st hour, which might seem long to some people, but in my experience that's better than I can usually hope for when it comes to having a time frame. Their worker (I'm terrible with names, unfortunately) was very friendly and professional. My system has been having trouble keeping the 2nd floor of the house cool, and I'm a new home owner so I had a lot of questions, but he was patient and listened to every single one. He took the time to explain things to me and talk about what the problem was. Unfortunately, he determined that the main issue is that my air flow unit is over 30 years old and that my AC unit was installed separately causing my whole system to run inefficiently; all of which was not something I could get addressed that day. But he took the time to talk to me about things I could do to help alleviate the problem in the meantime and explained that when I replace it I need to be sure to replace the AC unit as well. He also let me know about several programs through my power company that would provide some reimbursement for when can I upgrade my system. He also determined that I was low on refrigerant and needed about a pound added. He was able to replace that for me right away. I have an older system so the refrigerant was actually the bulk of my total cost. All together I paid $98 for the inspection and labor and $150 for the refrigerant.
Description of Work: I hired J&K to do an annual cleaning and maintenance check up on my HVAC system.

Great! I called around 3:00/3:30 to see if they could come out and they were able to get someone here by 6:00 which was amazing. We have been using J&K for 6 years and in fact use them because the prior owners had used them for years as well. Service is always professional, the people they send are friendly, knowledgeable and responsive. The person on the phone is great too, very friendly and called me back when she said she would.

We hired a vent cleaning service to clean our furnace vents and duct work last year via Angie's List, who I have reviewed elsewhere. We were awakened in December at 2 AM by our carbon monoxide monitor, which registered near lethal carbon monoxide level. I turned off the furnace, turned on the vent fans in all bathrooms, opened all windows and doors and forced the air out. Kyle of J & K came out to help me. He checked the readings on our carbon monoxide monitor against his professional caliber carbon monoxide meter and discovered it was underreporting the levels of carbon monoxide. After some time spent in our still gaseous basement, he discovered that the vent cleaning company had damaged our furnace vents, as well as breaking our Aprilaire 5000 air cleaner. We already knew about the air filtration problem , but had no idea they had actually damaged our vents. Kyle and the staff of J& K (who were NOT the people who caused the vent and filtration damage) rearranged their entire work schedule for several very busy days to fit us in at the top of their list. They spent two days with us, totally replacing our furnace vents. We have not had a single problem since they did their work. We are deeply grateful to them. They dropped everything to help us, which they did effectively and at low cost. You can't find a better HVAC company than J& K. As to the vent cleaning company, I notified them of the problems. They reimbursed me for what I had paid them, but we had to swallow the cost of the furnace and air filtration repairs. Be very careful who you hire to clean your vents. The folks we hired came highly recommended via Angie's list. Read all reviews.

Last November, J&K serviced the Furnace at our home on Highboro Dr., Bethesda after it was taking a very long time to heat the home. Tony & Scott came the same day I called, cleaned leaves & other debris that had been sucked in from outside, flushed trap & drain. ran pump & cycled the heat. They checked to make sure everything was running OK. Total charge was only for the minimum service charge of $96. I have called J&K for HVAC service for our properties since Feb 2010 when the furnace in our Wilson Lane, Bethesda home died during the blizzard. I searched Checkbook.org & found Kyle from J&K who came through the deep snow & offered a Trane 95% Furnace for $2706 total installed. Last summer, during the heat wave, Tony & Scott replaced the dead AC unit in our Wilson Lane, Bethesda home for less than $3000. J&K has serviced several of our other properties in Gaithersburg & Bethesda. Kyle is the owner of this this family run company. His wife (Linda), daughter (Leslie) & staff (Chelsea & Karissa) handle the office while Kyle, his son (Scott) & Tech (Tony) service customers in the field. Tony is an amazing friendly wizard who can diagnose, explain & repair anything. J&K is Very Efficient, Professional,Friendly with Extremely Reasonable pricing! Very Highly Recommended!! --Milan from Bethesda, MD

Very well. Speedy service. Moderate labor costs: $125 for a half hour. Cheering to know we have no visible cracks in our high efficiency furnace, which J and K installed 10+ years ago. We have had very positive experiences with this company for the last 10 years. When we had them put in the furnace, J & K was the low bidder on the job. We have found them to be excellent and have had almost no problems at all with the furnace and air conditioning in ten years.
Description of Work: Checked blower rotation. Ttightened electrical connections. Primed trap, flushed and testing draining system, checking the condensate drain lines. Replaced media filter and cleaned pre-screen. Ran heat so could check the system's operation. Checked voltage and amperage. Checked safety controls. Checked vents. Recommended purchase of new pump as 10 year old pump is failing leading to poor draining and excessive noise.

Their work was outstanding. They replaced both the outside heat pumps and the inside electrical furnances for the two existing heat pump systems. We also had humidifiers installed on both units. They removed and hauled away the existing equipment and made slight adjustment in the existing duct work to ensure that I received the benefits from the new systems and their higher efficiency. They started at the scheduled time and completed the work on schedule. The staff was very professional and I am very pleased with the work that was performed.
Description of Work: Replaced two heat pump systems. They responded quickly to my request for an estimate. Mr. Fleming provided me with a list of options and explained the advantages and disadvantages of each option. There was no effort on his part to try to steer me to the more expensive option and his explanation of what needed to be done was clear. After additional checking their bid was the lowest and they performed the work.

Overall it went extremely well. I called this morning thinking I would get an appointment in 24 hours but instead they scheduled it for later in the morning. Got a call letting me know he was on his way and he was there within 10-15 minutes. Extremely knowledgeable, polite and answered all my questions.

The office staff set the appointment to occur within 2 business days. The technician showed up on time and gave a promopt diagnosis. He was friendly and professional.
Description of Work: The technician determined that my Trance packaged Terminal Heat Pump had a blown compressor and recommended that I replace the entire unit rather the the compressor alone becuase the cost was not that much greater and I would have all new parts. I took his recommendation.

I got several bids to install the Mitsubish "mini-split" unit in my home office. I had a through-the-wall A/C unit for years, combined with electric baseboard heat. The heat was fine, but I was having problems with the A/C unit and was tired of the level of noise, so decided to have a mini-split unit installed. I got several bids from recommended companies for the unit I wanted and J and K was the lowest by several hundred dollars. Even though they had a preference for another brand, they were happy to order and install the one I requested. They were prompt, professional, neat, extremely pleasant, and did a great job with both the indoor and outdoor installations. The unit is everything I had hoped it would be, and I am very pleased.

I got two estimates for replacing a through-the-wall AC in my home office with a Mitsubishi "Mr. Slim" mini-split combination a/c and heat pump. Both Jand K and the other company were highly rated in Angie's List and by Washington Checkbook. I chose Jand K, even though it had fewer reviews, because the estimate was $450 less than the other estimate for the same unit and the same work (both required that I have electrical work done by my electrician prior to the installation). The Jand K representatives were very responsive and professional, and I am very pleased with the job they did. I should note that I did my own research regarding which product to buy; Jand K insisted that several were comparable, including a couple that would have been slightly cheaper (and are apparently easier to install), but they respected my choice and I am very happy with the unit I selected.
