WHAT GETS FIXED
When your furnace stops heating or starts acting up, Air Comfort handles furnace repair and heating repair for homes in York, Manchester, Dover, Shrewsbury and across York County. It’s one of the heating services in York County offered.
Furnace repair for York County homes, for all major brands and every fuel type: gas, oil, propane and electric.
In a York County winter, your furnace runs for long stretches, and a small problem can quickly become no heat. If a furnace won't start, blows cold air or keeps short cycling, the cause is often a worn ignitor, a dirty flame sensor, a tripped limit switch, or a problem with the inducer motor or the blower. On high-efficiency furnaces, a clogged filter or a blocked condensate drain can make the system shut itself off. On oil furnaces, a worn burner nozzle or a clogged oil filter is a common cause of no heat. Air Comfort can also inspect the heat exchanger on request.
Common furnace problems repaired:
24/7 heat pump repair for York County homes, in both heating and cooling modes, for central heat pumps and ductless heat pumps from all major brands.
In a York County winter, a heat pump does most of the work of heating your home, so small problems show up fast. A system that runs nonstop, blows lukewarm air or keeps leaning on its backup heat can often be traced to airflow, the defrost controls, the outdoor fan or the refrigerant charge. Some frost on the outdoor coil is normal, and the defrost cycle should clear it. An outdoor unit that stays covered in ice, or a system that seems stuck in defrost, needs a look.
Older heat pumps can lose heating capacity in deep cold. Newer cold-climate models, like Mitsubishi Hyper-Heat ductless systems, are rated to heat down to -13°F. Learn more about heat pumps.
Common heat pump problems repaired:
Regular-hours visits start with a $109 diagnostic, waived if you approve the repair. Boilers and ductless mini-split systems are repaired too.
Please note: residential systems only, and no service on systems homeowners installed themselves.
FRESH FROM THE FIELD


YORK, PA
Early this heating season, a York homeowner called about a Trane furnace that wasn’t putting out any heat. The furnace was showing an error for not seeing flame and had locked itself out. When the burners were pulled, they were rusted, and that rust was keeping the flame from carrying across to the flame sensor. The burners, the flame sensor and the condensate trap were cleaned, then everything was put back together and its operation checked. The furnace is heating normally again.
YORK, PA
On a mid-October call in York, a Goodman gas furnace had a couple of issues worth knowing about. The temperature rise across the furnace was 70F, while the data plate lists a range of 35-65F. In other words, it was running hotter than it was designed to. Increasing the airflow brought the rise down to 55F. The control board’s history also showed a no-flame fault, so the flame sensor was pulled and cleaned. After that, the furnace was operating as it should.
If you notice any of these, Air Comfort can diagnose the cause. A yearly furnace tune-up can help catch some of these problems early.
This often points to a power, ignition or safety-switch problem.
Possible causes include an airflow problem, an ignition or flame sensor fault, or a safety shutoff after the furnace overheats.
Weak airflow can come from a blower motor problem, a clogged filter or duct issues.
Short cycling can come from airflow, thermostat or sizing issues. Learn why your heater keeps turning on and off.
Banging, squealing or burning smells can mean a part is wearing out or failing.
Rooms that stay cold can point to airflow or blower problems.
A furnace that isn’t working as it should may run longer to heat your home.
