My husband and I had the pleasure of dealing with Mr. Bralette of GK Mechanical by way of referral from our home warranty company. Scheduling was responsive, quick and easy, and we secured an appointment right away. Mr. Bralette was on time, professional and very knowledgeable about our HVAC system. His diagnosis was right on point and gave us valuable recommendations for keeping our system running efficiently. Parts were ordered, and we look forward to his return.

Todd was very professional and pleasant! He gave me recommendations regarding my ac unit. I will be contacting him again.

Ingrid V.

Todd was super helpful and very knowledgeable about what he does. He thoroughly explained the process and offered options if the warranty would have declined. Our install was scheduled and completed the very same day when the parts came in. They offer great service plans and personal service. GK will have our business moving forward.

Eric V.

My Service Technician Todd was the absolute best. The constant communication and through explanation of what he was doing to my system was the best. I recommend this company and Todd 100%.


Todd was amazing! Not only did he spend ample time diagnosing the issue, he also checked around the house for any issues and even carried my portable ac unit upstairs for me! 10/10 would recommend.

Kimberly W.

Mr. Pete was very informative and friendly to talk to with occasional jokes and humor to lighten the stress of possibly having to pay to replace an A/C unit. He did a great job with his thorough investigations in an attempt to find the issues. We really enjoyed Pete's professional, courteous, and humorous visit today. He's really good at his job.

Tee B.

Todd was a tech wizard. Educational, great bloke and family oriented. We have a young child so having A/C work is important. Todd was able to access, evaluate and solve our issue. Highly recommend these guys!

I'm a realtor, and have used GK Mechanical for my personal residence and my rental property. I've also referred GK to several of my clients. Everyone has been pleased with their professionalism, customer service, and the quality of their work. Gerald Kosh, Todd Krems, and his entire crew are fantastic!

Gretchen G.

Todd from GK Mechanical was very prompt, he did a great job explaining what the problem was with my AC unit, and he also gave a very reasonable price for the repair. In addition, he checked my other AC unit while he was out just to make sure all was well.

I would definitely use GK Mechanical again!!

Josh S.

GK mechanical was OUTSTANDING in there professionalism, promptness, and ability to communicate. My hvac unit "froze" in my rental property and they were able to fix the problem with no issues in a timely manner. Pete was my mechanic and he was not only professional, but down to earth, easy to talk to, funny, prompt, and extremely professional. I ended up signing up for their silver maintenance plan after using them. I would strongly recommend this company for anyone having issues or concerns with their hvac unit.

Richard P.

Michael and his partner was excellent!!! If I could give him a raise I would!! He was on time, professional, and explained everything!!! He also went over the cost for a new system. I hope to get him if I ever need work done on my AC. He was also VERY knowledgeable!!!

Wanda S.

Todd did great job, very friendly and you can tell he absolutely loves what he does. I would strongly suggest and recommend Todd and GK Mechanical Team for Heating and Cooling needs!

Thanks Todd!!

Todd K.

Pete has been to service and consult on the temperature units in our home a few times now. He is friendly, professional, quick and knowledgeable. Our landlord hired him, but I would recommend.

Jamie A.

Todd was very professional, knowledgeable, communicated throughout the entire process and corrected my AC repair in a timely manner with very fair pricing. I would recommend using them to anyone!

Lori G.

Excellent customer service from Todd K. He was very knowledgeable, kind and professional. He actually did follow up on the project to make sure we got what was needed to get the issue resolved.

Berkina P.

Todd is a hard working man that provides services above and beyond the minimum requirements. Todd is a good family man and genuinely wants to help people with their HVAC needs just like they were part of his family. GK Mechanical has fair prices and will match any estimates from other contractors.

Steven K.

Todd was so helpful and knowledgeable! Todd offered great options since our home warranty declined to cover our original furnace in Aspen Park. He offered no interest financing and a top of the line unit at a very reasonable price. Our install was scheduled and completed the very next day! They offer great service plans and personal service. GK will have our business moving forward.

Michelle S.

Todd was absolutely amazing! He was friendly, polite and very knowledgeable. He walked me through each step of the process and thoroughly explained things I did not understand. His willingness to answer all of my questions and assure I was informed as a consumer and homeowner was the best part of my experience. That's a lot Todd! Will definitely be using this company again if the need arises.

Quyan S.

The assigned Tech Todd went out of his way to help us get heat in this very cold weather. He personally sacrificed his family day and came on a Sunday. He did an act of charity for us who had been in the cold for over a month. He is an asset for the company, GK. Thank you, Todd! The company must reward you.

Tita A.

We hired GK Mechanical to replace our HVAC in our rental property. Gerald was responsive and offered competitive pricing with an interest free financing option. He was knowledgeable and was able to start the job right away. We are very pleased with the work and looking forward to using him again in the future.

Elenna S.

GK mechanical did wonderful Maintence on my hvac system with a reasonable price. Great company.

Jackson P.

Technician Todd was great. He provided knowledgeable feedback as well as personalized, custom tailored support along with options for future service.

Mike S.

All technicians who have come to my home have been professional, knowledgeable and personable. The most recent tech Todd recommended things to make my equipment run at its peak for as long as possible. I thank him for this.

I would recommend this company on the whole as I have had nothing but good experiences with them, the equipment and labor are reasonably priced and my new HVAC and thermostat has been outstanding!

I feel that they will help me to keep my equipment in good working order and make sure I have the best experience possible with their equipment, office staff and technicians.

Eric W.

First of all Todd is an amazing being and completely detailed about his work. He was truly great, we'll keep him as family! Thanks Todd!!!

Daaron H.

John and Charles showed up on time, explained everything and completed the job with no issues. They were very clean and careful about bringing the heavy equipment upstairs without damaging the floors. In 6 hours I had cool air that's been working great for 9 days.** Highly recommend!

K S.

Nothing but positive experiences with this company from the start. The day our AC went out, a technician came out to assess the situation and determined we'd likely need a new compressor or a full unit replacement. They scheduled a follow-up visit for a few days later - AC went out on 7/3, of all days - and we received a reasonable quote from Gerald. Two days later another tech came out to do the installation, and our AC has been running smoothly and keeping us cool and comfortable ever since. This is the first time I've had to replace an AC unit, so I went in with few expectations, but everyone we interacted with was kind, courteous, and knowledgeable, and seemed to be very thorough in their work. We'd be more than happy to hire them again.

Erin V.

I had a positive experience with GK Mechanical. They were quick to reply to a Yelp request, agreed to work with our home warranty company, and were efficient in scheduling the repair. Their technician, Pete, was professional and competent and managed to solve the issue with our old A/C units. The AC units have been working flawlessly since he serviced them this past week. Recommended.


I first worked with GK mechanical in December 2019. My electric bill was coming in at $900 a month during the winter and I had no clue what was wrong. I had two other companies out to see what was wrong and nobody could figure out. GK sent John out and he listened to my concern and was able to find the problem. My bill went down 60% and the system worked perfectly. Just this week I had to call Monday night when my air conditioner went out. John came out same day, cleaned my system, changed my seriously old filter, and added refrigerant. They are my go to for service moving forward. They are prompt, professional and are a great value for the service.

Lauren W.

Great work! Since purchasing my new home I've wanted a new thermostat that was WiFi enabled. When requesting a quote using Yelp the rep responded immediately and provided a quote.
The price quoted included a new Ecobee4 Alexa enabled and the labor to install. The technician contacted me 20 mins before the service window and arrived at the top of the hour. The install and setup took less then an hour.

Amazing work would highly recommend.

A I.

Color me impressed. I called my home warranty company to file a claim because i had issues with heating my home. They contracted with GK Mechanical, a tech came out the following day, assessed the issue, contacted the warranty company and within the hour I was approved for a new system. I was put on the schedule for the following week. The rep touched base with me over the weekend to let me know what was going on with ordering of the system etc. I received a text the day of install to inform me of arrival. Techs arrived on time, was respectful of my property and my time. Could not have asked for anything else. Keep doing your thing!


The staff and technicians from GK Mechanical are incredible! Professional, knowledgeable and friendly! I wouldn't trust any other company with my HVAC! They tell you what is needed, aren't trying to sell you on products or devices that aren't necessary and genuinely care about their customers! I highly recommend this company to all my friends and family!

Katherine S.

I was concerned and worried that it would cost me an arm and a leg to repair my hvac system. I called around to compare prices and when I contacted GK mechanical they were a lot more reasonable. To add to the reasonable price they were extremely professional and did an excellent job. I'm SO GLAD I went with them! I highly recommend them and moving forward I wouldn't dare choosing any other HVAC company. Do yourself a favor and choose GK mechanical for your next hvac service. You won't regret it!

Marlon C.

We requested to fix our HVAC because no heating. GK Todd is professional, communicate with me very easily and fixed it quickly. I recommended to use them.

Lee S.

This company is ethical and professional. I definitely will use this company for all things AC and heating. The technician was very knowledgeable about his craft. He took pride in his work and most of all he assured me the job would be completed correctly. The price was reasonable, I would've paid more because the quality and professionalism was outstanding.

GK is owned by a great friend of mine Gerald K. People of MD, you are in great hands with this company!! I also know an awesome technician there too by the name of Pete B. Between these two Gerald and Pete! Your problem will be solved!! GK is one of the best in MD!!!

Matt C.

My home warranty company put me in touch with GK mechanical. The tech came out and was kind, and explained my issue. The issue took a while to repair and even the owner came by and evaluated things. The price was beyond reasonable (although a bit much on my strained budget). I don't think any other company would provide such personal and kind service on a 7 year old heat pump.

D. S.

If I could give 10 stars, I would! My heat went out on a Sunday and, as to be expected, there was no one available at most businesses to come out. The owner, Gerald, took the extra step to come to my house personally to check out the problem as soon as he could and got me some temporary heat until the part for my furnace comes in. I could tell he was genuinely concerned and the price was reasonable and he wasn't trying to hard sell me on a new furnace which, when I'm ready to get one I will definitely be getting it from this company.

Also, he was very patient and personable. Thanks Gerald!!

Anne H.

On the coldest night of the year so far, my furnace stopped working. Gerald came to the rescue, found the problem and fixed it. He was very courteous and patient. His price was more than fair as well. Did I mention it was on a Sunday right before upcoming snow storm? I am grateful to have found this local business and will not hesitate to use GK again!
