A furnace that blows warm then turns cold partway through a cycle is usually shutting down on a limit switch, most often because a dirty filter or closed vents have restricted airflow. A furnace that blows cold from the first second is more likely failing to ignite at all. Short cycling every few minutes, no response to the thermostat, or a unit that runs constantly without reaching temperature each point somewhere different. In older Spencerville, OH homes with basement-mounted furnaces and retrofitted ductwork, restricted return air is behind a large share of winter callouts.

An HVAC professional will read the control board fault code first, then test the flame sensor, ignitor, pressure switch and inducer, check static pressure across the filter and coil, and inspect the heat exchanger. Pro HVAC connects homeowners in Spencerville, OH with professionals who handle natural gas furnaces. Call (321) 463-9811.

Furnace Repair FAQs

Frequently asked questions about Furnace Repair

Questions we hear most often about Furnace Repair in Spencerville, OH.

Talk to a real person
Why is my furnace blowing cold air instead of heat?
A dirty air filter restricts airflow and often causes a furnace to blow cold air. Turn the system off, replace the filter with the correct size, and wait 30 minutes before restarting. Check that the thermostat is set to heat mode and the temperature is higher than room temperature. In Spencerville, OH winters, a clogged filter can lead to frozen coils if ignored. If the problem continues after the filter change, the issue may involve the blower motor or limit switch.
Does my furnace have a reset button and how do I use it?
Many furnaces have a red or yellow reset button on the motor housing or control board. Turn power off at the breaker first, locate the button, and press it once. Restore power and test. Avoid repeated resets, as this can mask a serious problem such as a failing motor or overheating limit switch. In Spencerville, OH winters, repeated tripping usually means airflow is blocked or the heat exchanger is cracked.
Why is my ductless mini split not cooling or dripping water?
A mini split head that runs but will not cool usually has a low refrigerant charge from a flare-joint leak, a blocked outdoor coil, or a failed fan or compressor capacitor. Water dripping from the indoor head is almost always the condensate drain, which relies on a gravity fall or a small pump that clogs with biofilm. A blinking timer or operation light is a stored fault code that tells a technician which sensor or board is reporting. In Spencerville, OH these units often serve additions, attics and finished basements where they are the only heating or cooling in the room.
Do I need duct cleaning or duct sealing?
They solve different problems. Cleaning is worth doing when there is visible debris at the registers, evidence of rodents or insects, water damage inside the system, or drywall dust left after renovation work. Sealing is what you need when rooms never reach temperature, bills do not match the equipment, or the furnace runs far longer than it should. A musty smell is usually neither, since it normally starts at the evaporator coil or a standing-water condensate pan. Older Spencerville, OH homes with retrofitted ductwork more often need sealing than cleaning.
Can a dirty air filter really break my heating or cooling system?
Yes, and it is the most common cause of faults that look like equipment failure. A restricted filter makes a furnace overheat and shut down on its limit switch, freezes an air conditioning evaporator coil solid, and makes the blower motor draw high current until it fails early. Two things matter more than brand: the filter must fit its slot tightly, because a loose filter lets air bypass it completely, and a very high MERV rating in a system not designed for it restricts airflow enough to cause the same overheating it was meant to prevent. A filter that darkens within weeks in Spencerville, OH usually means duct leakage is pulling in unfiltered air.
