“High quality materials and work. Reliability. I was very pleased with the cooperation.”
“I recently hired Dmitry for several plumbing jobs — installing a new water heater, replacing the old pressure-reducing valve, and removing an outdated water filter while reconnecting all the pipes cleanly. He did an outstanding job from start to finish.”
“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 Dmitry at Primus Expert.”
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.
I have used Primus numerous times to repair heating and a/c issues in the rentals that I operate. They are always able to immediately diagnose and repair the problem. In addition their prices are competitive and they often have immediate availability. I would recommend them to anyone who needs help with an hvac issue.
Dmitry, is highly experienced and the prices are reasonable. I have a 5 ton unit at my business, that everyone told me it needed to be replaced. Dmitry and his team fixed the unit and it’s running perfectly. The price was very reasonable. I use him for my home and business.

the service was more thorough than I would have thought. I needed a thermostat replaced. the technician checked my entire hvac system. the thermostat installation was very neat.
Edwin L.
Can’t say enough good things about this guy. Had 3 other techs come out stumped - unsure how to fix my heater. This guy did it in under 24 hours. I’ve had quotes of people telling me to redo my entire hvac system and Primus fixed it in 2 replaced parts. Well worth the price this guy is amazing.
Rae-Sean R.
This was my first time needing a professional to come out and help and he was reliant, responsive, and professional. Not only did he get the job done, he was clean and made sure I had next steps to keep up the maintenance of my HVAC.
Jamar B.
Primys services my Hvac systems cleaned everything up for me, made sure everything was working properly. Told me AC may need fuel but its expensive as long as its working leave it be, call him when I feel it not working and he will be back! Otherwise nothing needed until next years maintance.
