Aberdeen homeowners need equipment that can handle winter heating demands and summer heat without excessive energy use. Our heating and cooling services cover gas and electric furnaces, boilers, heat pumps, central air conditioners, and ductless mini-splits.
We also work on the components that influence how effectively conditioned air reaches each room, including ductwork, thermostats, zoning controls, and air balancing. For homes with seasonal moisture concerns, humidifiers and dehumidifiers can help manage indoor conditions.
Our factory-trained technicians service different makes and models, with straightforward pricing and same-day appointments available. We also provide 24/7 emergency assistance when heating or cooling problems cannot wait.
If the furnace runs but certain rooms remain cold, the problem may involve more than heat production. Restricted airflow, duct losses, or a malfunctioning blower can prevent warmth from reaching the intended spaces. Our heating repair services include checking the equipment and its distribution system to determine what is preventing heat from reaching those rooms.
Different heating systems require different troubleshooting. A gas furnace may have ignition or burner problems, while a boiler may struggle because of circulation or control issues. With heat pumps, technicians also examine refrigerant operation, defrost controls, and backup heating when the system struggles to heat the home in winter.
An air conditioner may produce cold air yet still struggle to cool the house. A dirty evaporator coil, failing blower, restricted filter, or refrigerant problem can make it harder for the system to cool the house. Our air conditioning technicians check these possibilities rather than assuming every cooling complaint calls for refrigerant.
We also consider how the system handles humidity. If indoor air remains clammy despite a low thermostat setting, the AC may be switching on and off too frequently or struggling with restricted airflow. Identifying the cause helps determine whether a repair, adjustment, or equipment change is appropriate.
Replacing equipment presents an opportunity to correct limitations in the existing setup. An older furnace may have been oversized, or a central AC may no longer suit the home’s current cooling requirements. Installing an identical-capacity unit without reviewing those factors can carry the same problems into the new system.
Farnen & Dermer installs furnaces, central air conditioners, and heat pumps, considering equipment capacity, efficiency, existing connections, and distribution requirements. We offer free replacement estimates and financing options on approved credit, allowing homeowners to compare suitable systems before committing.
Maintenance is most useful when it reveals developing problems before they interrupt service. During a spring AC tune-up, technicians inspect electrical components, how effectively the system cools, condensate drainage, and airflow. Our AC maintenance services also help identify conditions that may increase operating costs.
Fall heating inspections focus on safe operation, controls, heat delivery, and components showing wear. Keeping both appointments on the calendar reduces the likelihood of avoidable seasonal interruptions and helps homeowners plan repairs before they become urgent.
From established neighborhoods to newer residential developments, Aberdeen homes can have different heating and cooling requirements. Equipment age, duct configuration, insulation, and room additions all influence the work needed. Our technicians assess these details when recommending repairs or upgrades.

These questions address three situations where understanding how your equipment operates can help you decide what attention it needs.
The system may have insufficient cooling capacity, restricted airflow, or an equipment-sizing issue. A technician can check cooling operation and whether the AC is removing moisture effectively.
Often, yes. Ductless mini-splits can serve rooms without existing ducts, provided the equipment is correctly sized and there is suitable space for indoor and outdoor units.
Backup heat assists when outdoor temperatures reduce the heat pump’s available heating capacity. Occasional operation is normal, but unusually frequent use may indicate a problem with the heat pump or its controls.
