On select heating and cooling systems
Severn homes rely on heating and cooling systems throughout the year as temperatures shift between Maryland’s hot summers and cold winters. Regardless of whether we installed your system initially, Farnen & Dermer is proud to provide expert HVAC support in Severn, MD, for all makes and models.

Founded in 1902, Farnen & Dermer is a fifth-generation, family-owned business with more than a century of local heating and cooling experience. Our technicians are factory-trained and qualified to work on residential HVAC systems. We continue to service the systems we installed years ago.
Most calls start with something you noticed. It might be a noise, or a bill that climbed without explanation. Our HVAC services in Severn cover both the equipment and the ductwork that moves the air. Our work includes HVAC repair and replacement, seasonal maintenance, and ductwork services. That range matters because the source of a problem is not always where its symptoms appear. Weak cooling, for example, can result from equipment problems, airflow restrictions, or ductwork issues. No matter what the issue is, our team is ready to help.
Repair is often the better option when the rest of the system is in good condition. A failed capacitor or a worn contactor rarely justifies replacing a unit on its own. As a system ages, the cost and frequency of repairs can make replacement worth considering. Watch for weak airflow and rooms that never match the thermostat. A system needing a second repair in one season is worth a closer look.
When the same part fails twice, the underlying problem may be elsewhere in the system. If refrigerant levels are repeatedly low, a leak may be the underlying problem because a properly sealed system should not lose refrigerant. We look beyond the failed component to identify the underlying cause and help prevent repeat problems.
A replacement conversation starts with your house, not a catalog page. We assess your current system before we discuss sizing. Insulation, duct condition, and how well the home maintains temperature can all affect equipment sizing. Proper equipment sizing considers the home itself rather than simply matching the old system. Financing is available on approved credit.
Your HVAC system can face significant cooling demand in summer and heating demand in winter. We recommend HVAC maintenance twice a year. Regular maintenance can help identify developing problems before they become unexpected breakdowns.
Spring HVAC maintenance prepares your cooling system for the season ahead. We clean the condenser and evaporator coils and clear the condensate drain line. We inspect electrical connections and other components for signs of wear or potential problems. We also confirm the system cycles correctly before we leave. Ductless mini-splits need the same attention as central systems.
Fall HVAC maintenance prepares furnaces, boilers, and heat pumps for the heating season. We inspect filters and other components that carry the heating load. Catching a problem in October gives you time to schedule a repair before it becomes an emergency.
Even a well-maintained system can fail without warning. Farnen & Dermer answers emergency calls 24 hours a day, seven days a week. Losing heat during freezing weather can quickly become an emergency. A burning smell from a vent or a complete loss of cooling during extreme heat also calls for prompt attention. If you smell gas, leave the house before calling anyone.
Severn’s winter temperatures can put sustained demands on heating systems, while summer heat and humidity increase the demand on air conditioners. Cold, damp winter conditions can cause frost to form on heat-pump outdoor coils during normal operation. Summer creates a different challenge, as your air conditioner also removes moisture from the indoor air as it cools your home. Regular HVAC maintenance can help keep your system operating reliably through both seasons.
We would rather tell you a repair will hold than sell you a system you do not need. Saying that is easy. Proving it means showing you the failed part and explaining what we found.
