The team at Farnen & Dermer is extremely helpful and knowledgeable. Their expertise helped me understand my boiler system and feel comfortable with it. They took the time to explain everything and walk me through checking my system. Definitely an asset to Farnen & Dermer!Steve H. -
"Fortunate to have contacted Farnen & Dermer."
My gas furnace (1987 vintage, rest in peace) died on a Saturday, November 20, 2021. Cold nights were forecasted. Called several HVAC emergency services with no luck until I reached Farnen & Dermer. Their HVAC tech arrived between 1-2 pm, communicated by text and phone. They deemed the unit unrepairable but offered a reasonable quote for a new gas and AC unit, which could be installed Monday/Tuesday. They also offered financing. After the furnace died again that evening, I checked their website and accepted the quote. Installation was scheduled for Monday morning, and their technicians arrived at 8:15, completing the job by 3:05 pm. Very fortunate to have contacted Farnen & Dermer.Kevin S. -

Air Conditioning Maintenance
There is nothing worse in the hot Maryland summers than to have your air conditioning suddenly stop working. Fortunately, you do not have to wait until you are experiencing a cooling emergency, or lots of humidity, to take care of your system. Annual maintenance on your air conditioner will help clean out the dirt and dust that has been accumulating over time, lengthen the life of your system, increase energy efficiency, and identify repairs before they become worse or cause a breakdown requiring replacement.
During your air conditioning maintenance appointment, our certified technicians will:
- Check operating pressures and temperatures
- Clean and inspect the outdoor unit
- Check the refrigerant level in the unit
- Monitor the air flow and check the evaporator
- Visually inspect your air conditioner for signs of wear or rust
- Inspect the overall function of the system
