It’s winter in North Carolina, you’ve just returned home from a hard day’s work. You notice it’s as cold inside your house as it is outdoors – brrr! This is just one of the many scenarios a problematic heater can lead to if you’ve failed to maintain it properly. If you’ve noticed that your HVAC system is acting stranger than a sighting of a penguin on Wilmington Beach, one of these five potential heating problems could be the reason for it.

Problem #1: Pilot or Ignition Control

A faulty pilot or ignition control can make it tough to heat a residential home or commercial space. The most common reason for a faulty ignition control is a cracked, disconnected or dirty ignition cable. Some of the most common reasons for an unlit pilot include clogs in the HVAC system, thermocouple issues or strong drafts.

Problem #2: A Malfunctioning Thermostat

The heating system’s thermostat controls and determines when to blow heat and how much of it. If your thermostat has started to malfunction, you’re likely to experience no heat or intermittent heat, because the power to blow the hot air into your home has been disrupted. A certified technician has the tools needed to run a test to quickly identify the problem and solve it as soon as possible.

Problem #3: Not Producing Enough Heat

There are many issues that could lead your heating system to not produce enough heat or no heat at all. As mentioned, problems with the pilot, ignition control or thermostat can all lead to not receiving enough heat from your heating system. Wear and tear on other common system components, such as fan motors, can also lead to a heating system that doesn’t blow enough heat to warm your home. With so many possibilities, it’s important that a professional technician troubleshoots the problem. Otherwise, you could be searching for the heater problem until the summer. That is if you aren’t frozen before it arrives.

Problem #4: The Blower Constantly Running

If your heating system’s blower is constantly running, first make sure that the thermostat isn’t calling for heat. To do this, set the thermostat to the lowest setting and make sure the room temperature is above it. If the system was running, allow a few minutes for it to shut down completely. If the blower continues running despite your adjustments, this could indicate an issue with the limit switch. If the heater’s burner hasn’t adequately heated the supply air plenum and heat exchanger, the limit switch’s purpose is to prevent the system’s blower from blasting cold air into your home. But don’t worry; a professional technician can replace a limit switch in no time.

Problem #5: Frequent On and Off Cycling

A heating system that continues to cycle between the ‘on’ and ‘off’ modes usually indicates a clogged filter. One of the easiest steps of heating maintenance is changing the air filter, which homeowners should do once a month during times when the system works the hardest to heat your home. Frequent cycling can also be the result of improper airflow, which happens when you have duct work that is either too small or damaged. Cold air entering the heat exchanger can also cause the heating system to cycle frequently. Last but not least, a bad thermostat setting can also lead to frequent cycling, so remember to check those settings to ensure it isn’t an easy fix before you call us for service. If you suspect your heating system is malfunctioning because of one of the problems as mentioned earlier, contact Carolina Comfort Air for immediate service. Considering how complex a heating system’s components are, we advise that you entrust a professional HVAC technician instead of trying to solve the problem on your own.
