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.

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.

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!
