  • These folks are top-notch.
    These folks are top-notch. Mr. Dermer was easy to work with. He clearly stated the job to set my expectations. The gentleman that came to do the work were very professional and walked me through the install. They kept things clean and were in and out in a day. This was oil to gas conversion. I would recommend for any future work.

  • We have no complaints and love our new system.
    Farnen & Dermer were excellent people to work with from start to finish. They were professional and knowledgeable. They answered all of our questions (and we had A LOT of questions.) They provided the lowest estimate and best warranty among the other HVAC companies we asked for estimates. We have no complaints and love our new system. Thanks, Farnen & Dermer!

  • They were professional and friendly.
    The Farnen & Dermer team did a great job installing our new HVAC unit. Jay was very helpful and answered all of my questions. The installation team came out the next day to install our new unit. They were professional and friendly. We had a great experience and would highly recommend F&D!

  • The work was more extensive than initially thought
    Charlie was absolutely wonderful! He was beyond courteous and friendly - easy to talk to! Determined the trouble promptly and explained everything - including a few tips to help keep our system in good shape. The work was more extensive than initially thought, but he was able to get everything completed in a timely manner! Would give more than 5 stars if I could! Please pass on my appreciation to Mr. Charlie! Thank you!

  • Charlie is extremely helpful and knowledgeable.
    Charlie is extremely helpful and knowledgeable. His expertise helped me to understand my system and feel comfortable with the boiler system in my house. He took the time to explain everything to me and walk me through checking my system. I couldn't thank him enough for the knowledge he provided. Definitely an asset to the Farnen & Dermer team! I will definitely have all of my systems serviced through Farnen & Dermer moving forward, all thanks to Charlie's top-notch service!!

  • They were very professional
    , afterThey were very professional installing the system you wouldn’t even have known they were there. Ed Dermer explained the entire process and the technicians did exactly what he said.

  • Friendly and knowledgeable
    Friendly and knowledgeable, recommended an air scrubber to help clear up some mold but wasn’t overly pushing the product. Would recommend

  • The application process was fast and easy.
    Farnen & Dermer’s product offerings, pricing, and the 60 month - O % payment terms have definitely convinced us to upgrade our heating/cooling systems and water heater. The application process was fast and easy. The York systems were promptly installed and when unforeseen issues later came up, service was promptly dispatched and problems rectified the soonest possible time. We like that they are reachable even on weekends. The technicians are highly experienced and pleasant to deal with like the owners. We hope to keep our systems in good condition with the company’s assistance in the years to come.

    Friendly and responsible crew. Installed and leveled equipment well. Good troubleshooting skills. Kept my home clean and protected by installing in wet and muddy weather. Priced the job well from the initial quote. Very responsive in communication.

  • The Farnen and Dermer team is Fantastic!!!

    The Farnen and Dermer team is Fantastic!!!

    To Ed Dermer and the entire Staff, you are the best. We Did our research on a number of trade dealers. Farnen and Dermer were very reasonably priced. More importantly, their turnaround time and execution were exemplary. Charlie and the team came out to visit us first. They shared with us what we already knew. We needed a new furnace/air conditioning unit. The entire team came out at 12 o’clock the same day and only an hour after we said to change it out.

    They removed and installed our entire system on the same day. It’s nice to get a reasonable price and great service. It’s even better to know that the people that worked all day for you were having fun joking around and getting along great. You have a great group of people thank you for your help

  • Couldn’t be more pleased with the quality and workmanship
    We have been using Farnen and Dermer for 15 years. We have used them exclusively for all of our HVAC renovations and maintenance and couldn’t be more pleased with the quality and workmanship they continually provide along with fair and competitive pricing. Today we found a leak in our 80-year-old sewer line from our new second-floor bathroom to the basement. We were so alarmed imagining walls and ceiling that might need to be removed. Instead, the leak was found in an exposed area of the basement and it was repaired quickly and expertly. Thank you to Jason for your excellent diagnosis and speedy repair. Once again Farnen and Dermer saved the day!!

  • Always an asset when home maintenance gets you frustrated.
    Charlie is the best. He is a long-time F&D technician and he does it all...plumbing and HVAC. He also knows boilers, hot water radiator systems and how they work, and how to keep them operating. Plus he is a warm and kind person...always an asset when home maintenance gets you frustrated.

  • They were courteous and professional.
    We had Sean and Calib today. They were courteous and professional. They installed 5 sinks in a very timely manner and all is well. Would highly recommend them for your next plumbing job.

    They are very quick to respond, very courteous, very caring. I have been dealing with them for about 15 years and they always send us Charlie who is the nicest person! He is courteous, knowledgeable and a pleasure to work with. I highly recommend them!

  • They are absolutely the best.
    I just can't say enough positive things about this company. The owners are fabulous people. The workers are extremely kind, attentive and knowledgeable. They apply plastic film over all of the Carpeting and Flooring in the areas that they are working and place tarps over any other items that may pick up debris from the installations. They are absolutely the best. I strongly recommend that you consider using them for any type of HVAC and plumbing work.

  • Honest pricing and great customer service.
    Farnen & Dermer just completed a follow-up appointment after installing a new AC unit and condenser. One of the fears of being an AC customer is how a company follows-up post-installation. This has been a great experience and the reason why we chose Farnen & Dermer for our new home. They installed a full system in our previous house after the Great Catonsville Flood and did a fantastic job with honest pricing and great customer service. They knocked it out of the ballpark for our family a second time. I can't recommend them enough.

  • I was impressed.
    I was looking to replace my 22-year-old furnace and AC unit. I received three quotes and Farnen & Dermer was right amongst all the range of bids. Honestly talking to Ed, was what convinced me to go with their team. Ed's experience and the way he broke things down to me were perfect. I don't know heating or AC, but he told me why I did not need all kinds of upgrades, he told me what I needed...nothing more, nothing less.

    We scheduled a system replacement for the next day. I was told the team would show up at 8:45 am.

    Well, guess what??? Keon, Jake and Caleb showed up at 8:40...ready to go. Jake explained everything, while Keon and Caleb started the removal of the old system. The old one was gone before I knew it.

    They worked as a great team. All taking time to say hi to Dudley our dog, or to update me of where they were in the process. They were truly a great group of hard-working guys. Not once did I ask a question that wasn't answered or explained so I could understand it.

    It took the whole day, but in the end, my house was definitely improved upon. The system is great. The savings by converting to gas will be significant. The house was clean, nothing out of place, and my new system was installed, running and I was impressed.

    Great job to the entire team at Farnen & Dermer!!! You guys rock!!!

    Oh by the way. 0% interest financing for 60 months. With the savings on the utility bill, it basically pays for itself.

  • Fantastic service!
    Fantastic service! We needed the first-floor air conditioning replaced and F & D responded promptly and were there the same day because it was the hottest day of the year! They even cut the bushes around my outside air unit! The installers were really nice and answered every question. Customer service followed up and made sure that we were satisfied and that the unit was working. I highly recommend Farnen & Dermer for your air conditioning.

  • They cleaned up everything and were personable
    I had a great experience with Farnen and Dermer. My heat pump broke and within 24 hours of contacting them, they installed a new system and had my home cool again. The installation crew and diagnostic technician took the time to answer all my questions, no matter how simple or basic. They cleaned up everything and were personable and polite the entire time.

  • Very prompt and communication was smooth.
    I have a rental property and the AC went out, 15 years old. I called to get several bids for replacement on Tuesday. F&D came to do the estimate within an hour of calling. I had a written proposal immediately. Zach was very prompt and communication was smooth. After reviewing all bids, I found that F&D was the best value. I called them back the next day to purchase with F&D. They scheduled for Friday. Brand new unit purchased and installed in the middle is summer within 3 days is impressive.

    - Terry H.

  • They always are quick to respond
    The guys have done lots of jobs for us over the years. They always are quick to respond, especially on emergency work. My AC went out on a Saturday night this summer and I was able to get someone that night and they had it fixed the next morning. My water heater went out and we were able to get it replaced the next day. They are very accommodating with special requests and won’t push anyone's brand or approach. They do excellent work and will be my first call on just about any job.

I truly can not say enough about the professional integrity of this company!!!!! they help make AMERICA GREAT AGAIN with their excellent amazing service!!

  • We've always been very pleased with their work!
    We've always been very pleased with their work! We have used them for over 30 years, for multiple projects, at two different properties. They are always on schedule, they have a fair price & they clean up after the work is done!
