Leave Us An Honest Review

Our HVAC system is nearly 30 years old and showing its age. We had three companies provide quotes, and Farnen and Dermer offered the most appealing package in both price and equipment. Charlie inspected our system and made recommendations, explained financing options, BGE electrification rebates, and federal tax credit benefits. Caleb and Mike handled the installation, answered all our questions and concerns, reviewed preventive maintenance and warranties, and gave us a thorough tutorial on the thermostat. They even shipped us a box of goodies — seriously, who does that nowadays? Overall, excellent customer service, knowledgeable and competent technicians, and a highly recommended company.

I’ve been using Farnen and Dermer since I bought my condo 15 years ago. They are always professional and arrive within the scheduled time window. The technicians are pleasant and knowledgeable. Today’s yearly maintenance was quick and easy — always a pleasure to work with them.

We made an early morning call to Farnen & Dermer due to a leaking hot water heater. The gentleman I spoke with was pleasant and responded quickly to our emergency. Within less than an hour, a wonderful technician named John arrived to assess the issue. A very reasonable price was quoted, and we promptly approved the work. Shortly after, Mike and James arrived to begin the installation. They were professional, extremely knowledgeable, and very funny. It was a genuinely pleasant service call, and I highly recommend anyone needing service to reach out to them immediately — you won’t be disappointed! Thank you again for such a great experience and exceptional customer service!

Charlie did a great job. I truly appreciate his patience, honesty, and straightforward approach. While I wasn’t happy with the repair cost, he took the time to explain why the repairs were necessary. He’s an excellent representative for his company — can I hire him?

My experience with Farnen and Dermer was excellent. Both technicians did a great job explaining their work and answering all my questions. The initial sales experience was also great and very easy. This wasn’t a purchase I was looking forward to, but they took a lot of the stress out of it. I would recommend them to anyone in the same situation.

These guys are outstanding. They handled our HVAC replacement many years ago and have provided semi-annual maintenance ever since. They’re thorough, professional, and keep us informed every step of the way. Our technician on this visit was Keon, and he’s a true credit to the team.

Farnen and Dermer are my go-to team for all my HVAC needs. Charlie P. was able to identify and resolve an unexpected issue within 20 minutes. He’s extremely knowledgeable and was also there supporting me through my entire new installation a few years back! It’s great to have familiar faces you trust coming back to help — it says a lot about the company and their employee retention. Thanks, Farnen and Dermer!

Farnen & Dermer came out the same day we called. We got a new AC unit and furnace at a fair price — no gimmicks, and the estimate was all-inclusive. The installer explained everything clearly. We’re very happy with the quality and highly recommend Farnen & Dermer!

John did a wonderful job with our HVAC system. For some reason, I couldn’t turn it on, and it was also time for maintenance. He spent a few hours diagnosing the problem, and thanks to his expertise, he found and fixed it. He arrived on time, greeted us with a warm smile, and was very respectful. He went up and down the steps multiple times without complaint. All the employees I’ve met so far have been amazing, and their work is excellent.

I’ve known Farnen & Dermer for many years. They’ve done work for numerous family members of mine, and I’ve heard nothing but rave reviews. Not only are they excellent at what they do, but they’re also a family-owned company, which makes working with them feel more personal and welcoming. I highly recommend contacting them for your HVAC or plumbing needs. When you call during business hours, you’ll likely reach Zach, the youngest family member at the company — he’s friendly, helpful, and, most importantly, knowledgeable. Highly recommended!
