A heating system that blows cool air, cycles on and off, makes strange noises, or leaves certain rooms chilly can make a Maryland winter feel a whole lot longer. Mercury Home Services provides heating repairs in Fallston, MD, and the surrounding areas for homeowners dealing with no heat, uneven warmth, thermostat issues, airflow problems, and systems that need a trained eye before the cold settles in.
Mercury Home Services is a family-owned HVAC contractor based in Fallston, MD, serving local homeowners. Our team specializes in diagnosing and repairing furnaces, heat pumps, electric furnaces, gas furnaces, and oil furnaces. During a heating repair visit, we check the parts and problems that commonly affect performance, including burners, heat exchangers, ignition systems, thermostats, airflow issues, unusual noises, and short cycling.

Our heating repair work focuses on finding the source of the problem, explaining the fix in plain language, and helping your home feel warm again.

Furnaces rely on several parts working together, including the ignition system, airflow components, fuel supply, and built-in safety controls. As a local heating contractor, we service gas, electric, and oil furnaces when parts wear out, burners act up, or the system stops heating properly.
Heat pumps operate during heating and cooling seasons, so they can show problems in several ways. Our technicians check components that affect heating performance, airflow, cycling, and overall system operation so your heat pump can return to steady operation.
Poor airflow can make your system run longer while some rooms still feel cold. Our team checks filters, vents, blower components, duct concerns, and thermostat settings so the system can move warm air where it needs to go.
Ignition problems can keep a furnace from starting or cause unreliable heating. A professional heating repair visit can include checking igniters, sensors, burners, electrical components, and safety controls to ensure the system starts and runs properly.
No-heat problems need prompt attention, especially when temperatures drop overnight. Our crew tracks down the cause, whether it comes from the thermostat, ignition system, airflow, fuel delivery, electrical parts, or a worn component inside the unit.
Banging, rattling, clicking, or a system that turns on and off too often usually point to a problem that needs service. Our trusted heating company will inspect the equipment, identify the issue, and help prevent a small problem from becoming a bigger cold-weather headache.
A cooling system that runs all day and still leaves the house warm usually has something holding it back. Our air conditioner repairs help resolve issues such as low refrigerant, poor airflow, thermostat problems, noisy operation, faulty capacitors, coil problems, and failing compressors, so your home can feel comfortable again.
Old AC equipment can become noisy, inefficient, and less reliable when summer heat shows up. With our air conditioner replacement service, we assess your home's cooling needs, recommend the right system size, remove the worn-out unit, inspect the ductwork, install the new AC, and test everything before we leave.
Some heaters reach the point where repairs feel more like temporary patches than real solutions. For heating system replacement, we inspect your current equipment, walk you through practical replacement options, install the new system, check airflow, and set up the thermostat and controls for steady heat.
That one room that never feels right may need its own heating and cooling solution. Our mini-split installation service is ideal for additions, garages, workshops, finished basements, and homes without ductwork, providing quiet operation and better control over individual spaces.
HVAC problems have a bad habit of showing up at the worst time. Through our emergency HVAC services, we respond to urgent heating and cooling issues, troubleshoot the system, and work toward getting your home comfortable again as soon as possible.
Seasonal service helps your HVAC system stay ready before it has to work its hardest. During HVAC preventive maintenance, we inspect electrical components, test system operation, clean coils and filters, check refrigerant, verify voltage, review wiring, and look for worn parts that could cause trouble later.
A boiler that leaks, loses pressure, or heats unevenly can make home comfort feel hit-or-miss. Our boiler services focus on existing boiler repair and maintenance, including flushing, radiator support, baseboard heating support, safety checks, and efficiency improvements.
A properly installed heat pump can help keep your home comfortable through both warm and cold weather. With our heat pump installation service, we size the equipment for the home, install the system, connect it to ducted or ductless setups, and test heating and cooling operation.
Heat pumps work year-round, so small issues can show up in more than one season. Our heat pump repairs address defrost cycle trouble, reversing valve problems, sensor issues, compressor concerns, electrical faults, poor airflow, and systems that struggle to keep up.
Oil heat can be a solid fit for homes that need extra warmth during cold Maryland nights. Our oil furnace installation service includes sizing the system, setting up the equipment, handling tank and fuel line connections, checking safety details, and completing code-compliant installation.
A rough-starting oil furnace, uneven heat, or fuel smell usually means the system needs service before things get worse. For oil furnace repairs, we inspect ignition components, burners, filters, fuel delivery, and system components to ensure your furnace runs safely and heats more evenly.
Heating problems feel less stressful when the contractor shows up ready to explain things clearly and fix what actually needs fixing.

Your heating system may need repair if it blows cool air, makes unusual noises, cycles on and off too often, gives uneven heat, or stops responding to the thermostat. A heating contractor can inspect the system, find the problem, and help restore safe, steady warmth.
No heat can become an emergency during freezing Maryland weather, especially overnight or when vulnerable people live in the home. You should check your thermostat, breaker, filter, and fuel supply first, then call an HVAC contractor if the system still won't heat.
Heating issues often stem from dirty filters, ignition problems, worn burners, airflow restrictions, a malfunctioning thermostat, electrical faults, or parts wearing out over time. Furnaces and heat pumps work hard during cold snaps, so small issues can turn into bigger problems when a system runs longer than usual.
Most heating companies repair gas, electric, and oil furnaces, as well as heat pumps. A trained HVAC contractor can check the burners, ignition systems, heat exchangers, airflow, thermostats, and cycling issues to determine why your system isn't heating properly.
