I highly recommend them to anyone with HVAC issues
I’ve had the pleasure of having Farnen & Dermer guys work on my systems throughout the last couple of years, my most recent problem being my hot water heater. Shout out to Glenn, John and RJ. Those guys were so kind, thorough and professional, same as with all the guys. I highly recommend them to anyone with HVAC issues😊
Latresha davis
Would highly recommend them if you need an installation!
Really good experience with Farnen & Dermer. However, I feel the salesperson who initially looked at our broken system tried to upsell us with a UV light for an A/C-only system—even though he said he wasn’t trying to upsell us—that was only six years old and had no real issues with mold. I also felt that he was abrasive in the beginning of the appointment and couldn’t really communicate or articulate how he liked to work best (specifically, he asked me to stop asking him questions and told me he needed to figure out the situation before giving me the solution, which is fine, but he should’ve expressed that before he started working so that he didn’t come off rude when I was simply trying to remain informed about our system). He obviously was much friendlier once we put in a purchase order later that day with him. He also got us a discount to meet an original quote we got from this company months ago before we knew the system was broken. On top of that, my initial experience with him was all made up for with the incredible installation and service after we purchased the new system. Not only were they able to replace our system the next day, but the installation professionals were extremely communicative, helpful, professional, and honest. Would highly recommend them if you need an installation!
Alexandra Smith
They took a lot of the stress out of it.
My experience with Farnen and Dermer was excellent. Both techs who came did a great job of explaining their work and answered any questions I had.
The initial sales experience was also great, was also very easy. Believe me, this was not 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.
Patrick Gray
Very professional and personable
Very professional and personable, these guys are top tier, they came on time and finished at projected time. Will call them again.

The men did the job cheerfully and competently.
Replaced gas hot water heater. Between locating the water shut-off valve, moving the old heater out and the new one in, and reconnecting the gas line, it was a long job which the men did cheerfully and competently. So far so good.
Joan Roth
He does a great job.
Charlie Polite, my regular technician, is also prompt and friendly. He does a great job.
Steven Harper
I would highly recommend them.
As was the case 20 years ago when they did a boiler installation for me, the workers were very skilled, accommodated my requests, answered my questions, and tested the system thoroughly before finishing. I would highly recommend them.
Anthony Maranto

Overall excellent customer service
Our HVAC system is nearly 30 years old and showing its age. Had 3 companies give their quotes and Farnen and Dermer has the most appealing package in price and type of equipment. Charlie checked our system and made recommendations, financing options, explained the BGE electrification rebates, federal tax credit benefits of a new system. Caleb and Mike performed the installation, answered questions and concerns, preventive maintenance, warranties and gave a thorough 'tutorial' on the thermostat. Oh, and they even shipped a box of goodies. Seriously, who does that nowadays. Overall excellent customer service, knowledgeable and competent technicians, highly recommended company.
Ed R
We're very happy with the services
We recently had our HVAC system and ducting upgraded/installed in addition to having an old oil boiler replaced with an electric water heater. The crew was always punctual, respectful, and very efficient. We're very happy with the services and highly recommend Farnen & Dermer for your HVAC and general plumbing needs.

You will not be disappointed!!
We made an early morning call to Farnen & Dermer due to a leaking hot water heater. The gentleman I spoke with was pleasant and quickly responded to our emergency. Within less than an hour, we had a wonderful technician named John to come assess the issues. After that, a very reasonable price was quoted, and we quickly accepted to get the job started. Shortly after that, Mike and James arrived on the scene to begin to install. They were professional, extremely knowledgeable, and very funny. It was a pleasant service call and I highly recommend anyone needing services to reach out to them immediately. You will not be disappointed!! Thank you again for a very pleasant experience and providing exceptional customer service!!!
Tracey Pryce
I would highly recommend
On time, polite, clean, and explained the work that was done. I love the fact they send a text and email of a picture and name of the tech who is coming to your house. Nice peace of mind. I would highly recommend.
jennifer brocato
Very pleased with the service!
Farnen & Dermer was very responsive. I placed a service call on a Saturday with their automated attendant, requesting service on Monday at 9 a.m. By 7:30 a.m. on Monday, I had a text confirming my appointment. The technician, Charlie Polite, showed up around 9 a.m., diagnosed the problem, and suggested a fix to get more life out of our 16-year-old device. Very pleased with the service!
Jim Zerr

We wish we could give more than five stars!
We wish we could give more than five stars! From the time we called Farnen and Dermer to the finalization of our service, we couldn’t be more pleased. Farnen and Dermer installed central air conditioning and heat in our historic home restoration 19 years ago. What a coincidence when one of the same people who worked on the project 19 years ago showed up at our door. We needed an entirely new system as the current one was old and worn out. They provided service within 24 hours to include rental of a crane to lift part of the unit on the roof and install a very difficult carrier in the ceiling on the fourth floor in a very tight space. The crew was professional, very informative, and extremely expeditious. We couldn’t be more pleased. We will continue to use Farnen and Dermer in the future, for all of our HVAC needs. To our surprise, we received a large box full of goodies from the company, which was extremely thoughtful, but certainly not necessary. What I like about this company is that every person that is coming out to work your project has a little bio and a picture about themselves professionally and personally to introduce themselves before they get to your home. I don’t know of any company that is that personal in addition to being professional. Thank you, thank you, thank you!

Install process is seamless
This is the second time they have replaced my system. They replaced one 2 years ago at my old house, and when we bought a new house, I knew I would be calling them again. From quote to end of install—the entire process is seamless. One of the best things is recognizing the technicians that come; they're not random faces. Glenn, Mike, Eric, and James are just a few. They remembered me from my old house. I cannot recommend them enough!
