      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.

      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!!

      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.

      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 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.

      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.

      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 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.

      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.

      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

      "Farnen & Dermer - Professional HVAC Technicians with quality HVAC components at reasonable costs."

      Gas furnace died (1987 vintage, may it rest in peace) on a Saturday November 20, 2021. Cold nights were forecasted for the following week. Called several HVAC emergency service companies no luck until called Farnen & Dermer – was I lucky! A Farnen & Dermer HVAC Tech would be there between 1 & 2 pm that day, they communicated by text & phone call. Unit was deemed not repairable by the Tech, Although when he tapped on gas valve furnace sparked to life. The Farnen & Dermer HVAC Tech gave me quote for new gas & AC unit – reasonable price and could be installed Monday/Tuesday. I asked about financing, they had it. The HVAC Tech gave good advice suggesting I go to their website to investigate. Sadly the furnace unsparked its life that evening. I spoke to several friends about quoted cost, one friend recently had that ‘home’ company that gets confused with that “gas” company install gas & AC unit and said the quoted cost was good deal. My dog was not keen on being a hand warmer that evening so I went to the Farnen & Dermer website was ok’d for the financing and accepted their quote. Got a text Sunday afternoon wanting to know if HVAC system could be installed that Monday – SURE CAN - I texted back. Reply was HVAC Technicians would be there Monday morning 8-9am. HVAC Technicians communicated by text & phone call – there at 8:15, completed around 3:05 pm. Again was very fortunate to have contacted Farnen & Dermer

      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.

      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!

      "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."

      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.
