    Update: Farnen & Dermer could not or would not fix my AC system…read more I had it fixed by different company for $410! No sales pitch! No attempt to sell me new units/systems.

    If I could give this company zero stars I would. A routine maintenance check quickly turned into…read morewhat felt like a sales pitch - and ultimately a scam directed at a single mom who maybe didn't know any better. I was told my 2019 unit needed a replaced compressor and I was given an astronomical quote for the compressor of $9,000. I consulted with two other companies, and they stated that a new compressor (if needed) would be around $2,000+. The technician then suggested I should "just replace the entire unit" for $13,500 claiming it would be under warranty unlike the quoted $9,000 for a new compressor. What makes this even more concerning is that this company installed the unit in 2019 with previous owners and by 2026 they were already recommending replacing the entire system! After having other HVAC professionals look at the system, it became clear the compressor did not need to be replaced at all and was a misdiagnosis by the technician. To make matters worse, the technician left the equipment area messy and did not properly or safely reconnect part of the unit, both inside and outside. I had even sat out a new air filter for the technician to replace during this maintenance visit, and he instead he sat the dirty one outside of the unit. He never replaced the air filter with either the dirty/old one or put in the new one that I had set out and told him about. I would strongly recommend not working with this company unless you are interested in a scam, sales pitch, and unethical work.
