HVAC reviews in Washington, Maryland

Thank you Jake for your wonderful services and politeness and dedication. I was very impressed by Jake and the way he made us feel comfortable to ask questions at any time. I didn’t really know much about Duct services and what it was. I was told by my friend that I need to get the service. I very happy that I decided to do it with you guys. I really appreciate Jake professionalism.

NOT 24-7!!!

Very very unprofessional and deceptive practices

Very professional! A pleasure to work with!

Always great service, family owned and operated

Good service and straightforward communications

Poor Customer Service. Could be the work people I have ever worked with. Do not use these guys. They are a bad business.

Stay away! They only have one objective, how to overcharge client unethically.

In my recent experience I found that they have poor communication, tardiness, and deceptive practices.

H.D Johnson was very responsive to my call. They quickly diagnosed the situation and repaired the issue

Our Technician Mr. SALOMON, was very professional and extremely knowledgeable. He solved our problem very easily. I just wanted to thank him.

They were a no-show to an appointment. When I called, I was told that the plumber showed up and nobody was home (except I was home the entire day). Never got a call, just missed the appointment and took a day off of work for nothing.

They were fantastic at repairing my AC promptly and professionally. Highly recommend!

Even in the middle of the pandemic, HD Johnson was able to send a plumber out quickly to fix an unexpected leak. Salomon was able to quickly cut out and replace the damaged pipe, taking only an hour and using precautions like a mask and gloves. Thank you, HD Johnson!

On a Friday night in August the AC went out. A call to HD Johnson's emergency # got us a technician that evening. By Tuesday our system was repaired and up and running. Wow who could ask for better service than that. And, the staff who came to our house were efficient and friendly. If I could give them 6 stars I would. Washington, DC

We used this company for plumbing services for a new bathroom in an addition. We failed our initial plumbing inspection. On two occasions, the technician did not arrive on the scheduled day for installation. The owner would not return calls. When I was finally able to speak to him, he was rude. On one occasion, the technician arrived an hour and a half late, then left mid day to go to another job. On the final day of plumbing installation, the job not only took twice as long as it should have, according to my GC, there were things that remained undone that my GC will complete. The excuses for these unfinished items include, not having a saw that was sharp enough to cut off the bolts that secure a new toilet to the floor. Not having a simple O ring to stop the leak in a new shower head. This technician lost pieces out of the box for a brand new toilet. The technician was rude as well as the owner. I would not even give this company 1 star. They should not be allowed to stay in business. I have never dealt with a more unprofessional company in any field.

I used them for an issue with a mini split. They charged $120 for 1 lb of refrigerant. For info you can buy a 25lbs of R410 Refrigerant for $200. Be prepare, you will spend more than $400 for a basic repair.
