Highly recommend Dmitry. He is very knowledgeable and professional. I had other companies try to fix the problem with my air conditioner, and spend enormous amount of money. Dmitry found the problem that was actually very simple fix. If I knew this company earlier I will safe a lot of money and headache. Thank you Dmitry. Best Regards Luba

If you are looking for an honest, highly skilled HVAC technician in the Willow Grove, Bucks County or Mainline PA area- do yourself a favor and call Dimitri at Primus Expert. I have an older 25-year-old AC unit running on R22 refrigerant, and instead of immediately pushing for an expensive replacement like other companies do, Dimitri took the time to properly check my refrigerant levels, change the filters, and get it running efficiently. He is knowledgeable, helpful, and kind.

I hired Primus Expert INC for regular HVAC maintenance, and they did an excellent job. They completed outside cleaning, refrigerant checks, and a full system inspection thoroughly and professionally. They also added green pellets to the condensation line treatment to help prevent clogging. I originally wanted to schedule the service in April, but Dimitry was honest and explained that it’s best to wait until the outside temperature is at least 65 degrees.
