HVAC reviews in Fairfax, Virginia

We called AA RAPID to get a second opinion our our broken air conditioning on the recommendation of a family member. They sent someone out on the same day. Our technician, Cesar, came out to run a system diagnostic. We thought we would have to replace the whole AC unit (and possibly the gas furnace), but Cesar worked to find a replacement AC coil that would be compatible with our 10 year old Goodman AC unit.

The new coil was special ordered from New Jersey. The deposit was paid and the coil was ordered on a Tuesday and arrived the following Monday. Technicians Cesar and Yovany removed the defective coil and installed the new coil. The whole installation took around 5 hours.

Throughout the week, Cesar was responsive to our questions and kept us updated on the order progress. He gave us honest and realistic advice about part and unit replacement. After installation, he checked in to make sure that everything was working properly.

Thank you AA RAPID for taking care of us!

“Air conditioning repair “ we are so Lucky and grateful we were recommended AA Rapid Plumbing and Air Conditioning as we were in real bad shape having had called multiple companies who only wanted to have us buy a brand new system for a repairable machine. Our machine was leaking into drip pan instead of going down the drain tube. Everyone else except for Cesar with AA Rapid Plumbing didn’t even check to see if it could be fixed. Cesar was amazing and extremely knowledgeable and professional. Fixed the unit up and now we have no leak. Don’t waste your time on other places call AA Rapid Plumbing and Air Conditioning as they will treat you right.

Couldn’t be happier with the response and work. Called later night after 11 pm and a technician, Cesar, was at my house within 30 minutes. No one else I called was able to assist. Cesar was very knowledgeable and quickly diagnosed the issue with heater and had it up and running quickly. I would recommend AA Rapid any time.

Sooo grateful for AA Rapid fixing our furnace today. We called a few places and this company was much more professional on the initial phone call, so we got some info and decided to call them out.

We’re in Fairfax County, and Cesar was able to stop by a couple of hours later, show me what was wrong with the unit, and get it working again.

I enjoy learning and he educated me on the system and answered my questions.

He was communicative and friendly the entire time. We definitely recommend the company and especially Cesar.

Our heat pump started acting strange after the recent winter storm and we appreciated the quick and helpful service received from AA Rapid Plumbing! After describing the problem on the phone after hours to Carlos, he assured me that an emergency visit was not needed and that they could send a tech out the next morning. Cesar did a thorough inspection of our unit and confirmed that all was working as expected in the frigid conditions. We really appreciated the honesty to not charge for an unneeded emergency visit and the quick and easy scheduling for the next morning. We will definitely call again for future HVAC needs.

Amazing customer service !!! And great job !! Love them :3

Quick, efficient, easy to work with. Great company great people. I would highly recommend their services

Extremely professional and efficient. The customer service is the best i’ve received in a while!

Do not trust them! Jeoung's integrity and quality of service have gone down the drain in recent years. Avoid!!!

We have used services from Dynatech for almost 30 years. They are very skillful, knowledgeable, and provide excellent service!

The good reviews you see here are either old or fake! Find someone better. Was scammed out of $8000 for a new (used) HVAC by Dynatech.

Dyna tech is a truly an honest and professional HVAC company. We are a small commercial investor and management firm. We tried Boland and every other HVAC companies to work on RTU and self contained units. Every time repair is made everyone’s explanation of problem is different. Dyna tech explains the work and repair process. Fees are reasonable and they are very prompt. New install is always quoted after confirming parts costs. We would highly recommend Dyna tech for commercial HVAC work. Only reason I may hold back recommendation would be so that they are not overly busy^^. Thanks Dyna Tech!

Very happy with a recent Dynatech installation of a new heating and AC system. They are a great value for their service and also very knowledgeable technicians. Would highly recommend!

As one of the loyal customers for the last 10+ years, I strongly recommend this company to all the locals who need HVAC services. In every aspect, this company provides top-notch services: responsive, honest, good results with great knowledge with such a reasonable price. I just feel grateful to have this company I can rely on with ANY problems and questions re. HVAC of my residence and rental properties.

Jeoung is an expert in the HVAC field. He is highly trained and understands the ins and outs of residential and commercial systems. On top of that he is kind and reasonable. There is no other HVAC technician I would ever call when I need support. I highly recommed!

I have used Dynatech Service Company for over two decades. They have provided excellent HVAC service. I found their technicians trustworthy, knowledgeable and never leave a job until the issue is resolved. Excellent work and integrity. Highly recommend!!

For more than 10 years, I have used Dynatech HVAC frequently for a large commercial property management company. They have proven to be the best HVAC professionals I have had the good fortune to deal with in my 40+ year career.
Quick, professional and unfailingly honest describe Jeoung An and his company perfectly.

I have used Dynatech for 10+ years. Mr. Jeong An is very professional, honest and his prices are very reasonable. One thing I can trust is that he's never overpriced because I work with a lot of contractor's so I know the going rate. He has done various work from replacing a damaged control panel, replacing a new HVAC system and replacing a water heater. He goes above and beyond with customer service without trying to nickel and dime everything. I have never had any issues after he completes the job so I know that he has done great work.

Jeong is amazing! We have been using his company for our HVAC needs for our commercial units since 2016! He has always been very responsive and always fix the problems.

I didn’t know he services residential as well! Warranty company sent 2 difference techs from different companies came to diagnose the issue and I was provided two different results. So I had to check with Jeong to see if he services residential units and so glad he was able to come out! Jeong was able to fix the HVAC without the CRAZY CHARGES the other two were going to charge me.

I would totally recommend His service to anyone looking for a trustworthy tech with reasonable fees.

We have used Dynatech several times for our home HVAC services and installation over the past many years. Jeoung is always polite, professional, precise, and reasonably priced. This company is great to work with and we would highly recommend!

Was able to get same day service. Really happy that they were able to diagnose my AC issue and get it fixed the same day. Very courteous and respectful and super friendly with my dog. I would absolutely hire them again for any issues!
