Customer Testimonials

  " We called Dynatech for a second opinion, after being told by another company that we need to replace the system. The Dynatech technician, who happened to be the company President, Jeoung; showed up within 45 minutes as stated on the phone.

Quickly found the problem and replaced a part that cost us less than the other company charged us for their misdiagnosis. The system is running like new, without spending the hefty price for a new one.

Dynatech is the only company we'll call for all our HVAC needs."

Mr. Joaquin M, Homeowner, Alexandria, VA

  "This is our second time calling Jeoung. He is amazing and incredibly fair. He is on time and always explains whatever problem he finds in depth. He actually showed me the heating coils that were broken and how the coils weren't heating up properly because of it. This time our AC was out and he diagnosed it as a thermostat issue. He was quick, incredibly courteous and knowledgeable. I would recommend him to any and everybody looking for a great ac/heat repair. I find he can usually come same-day, which in the dead of summer, is a true blessing!"

Mr. Kory K, Homeowner, Alexandria, VA

  "When others would only give me a time range, he gave me a time, and was on time. He had us up and running in no time-- replacing a part and recommending that we replace another part closer to the cold season. Courteous, professional, prompt, and honest about what we had to fix now and what we could wait to repair."

Mr. Maxwell T, Homeowner, Burke, VA

  "Dynatech provided excellent service repairing my air conditioner units at my home. The technician originally thought that my compressors had gone bad, but when he discovered during the repair that the system was not correctly installed by the home builder, he corrected the problem and was able to simply re-charge the system with coolant while refurbishing the original compressors.

Even though I reviewed their diagnostic report and authorized work for what I believed would be approximately $2500 of parts and work, they were able to do the repair and the charges were about $800.

Thanks to Dynatech for their honesty and integrity!"

Mr. Rob H, Homeowner, Arlington, VA

  "Jeong was punctual, polite, and extremely personable. He took the time to not only do great work, but explained everything in layman's terms.
I am extremely grateful for his down to earth style of workmanship and I will definitely be using him again."

Ms. Ann Taylor, Springfield, VA

  "Jeong was a true professional. He showed up right on time, was polite, and gave complete and understandable explanations to what he was doing."

Mr. Tom W. McLean, VA

  "Jeong was very polite, efficient and knew oil burners. I am a retired builder, and was extremely impressed with his knowledge and expertise."

Ms. Karlene W. McLean, VA
