Your home’s HVAC unit, including the heating unit, performs many functions, such as ventilation, to make your indoor living spaces as comfortable as possible. A breakdown or malfunctioning of the HVAC’s components can lead to poor unit working. HVAC systems not heating is a common issue that several issues with your unit can cause. The following are some of the most common heating system issues:
The Air Filter Could Be Dirty
Confirm that the air filter is clean. Dirt, dust, and debris on the air filters could cause your system to work harder to give heat. Maintaining a clean filter can ensure your unit is performing at its best. Additionally, a dirty air filter can strain the blower motor, leading to potential malfunctions and reduced efficiency.
The Unit Could Be Turned Off or Unplugged
This may seem like a no-brainer, but you should confirm that your thermostat and heating system are plugged in and turned on to ensure the unit has a power supply. Ensure that the power switch is in the ‘on’ position to allow the heating system to operate correctly. You may refer to your unit’s manual guide for more information.
The Thermostat May Be Off or Set Incorrectly
Ensure your thermostat is on and set to ‘heat’. If the thermostat is on, reset it to your desired temperature.
A Tripped Circuit Breaker
Check your home circuit breaker box and reset the circuit breaker. An issue with the circuit breaker can affect the entire system, preventing it from heating your home. Ensuring the circuit breaker’s designated switch is flipped back to “ON” may get your unit running again. If you have checked the above issues and your unit is still not heating, you should consider contacting an HVAC professional to inspect and fix the problem.

Check for Clogged Vents and Drain Lines
Clogged vents and drain lines can significantly impact the performance of your heating system. If your vents are blocked, hot air cannot circulate throughout your home, reducing efficiency and increasing energy bills. Similarly, clogged drain lines can cause water to accumulate and freeze, further damaging your system.
To check for clogged vents, inspect your vents and ducts for blockages, such as dust, debris, or animal nests. Clean or replace your air filter regularly to prevent clogs. You can also use a vacuum cleaner or a specialized duct cleaning tool to remove blockages.
Check drain lines for signs of water accumulation or freezing. If you notice any issues, brush the drain lines with bleach and water to clear any blockages. Routine HVAC maintenance can help prevent clogs and ensure your heating system runs smoothly.
Overloaded Motor or Complex Issues
If your heating system is not working, it may be due to an overloaded motor or complex issues that require professional attention. An overloaded motor can cause your system to shut down. In contrast, problems such as faulty thermostats, malfunctioning blower motors, or improper installation can reduce efficiency and increase energy bills.
If you suspect an overloaded motor or complex issues, it’s essential to call a professional HVAC contractor to diagnose and repair the problem. They can diagnose properly and provide preventative maintenance to ensure your system runs efficiently and effectively.
When to Call a Professional
While troubleshooting can help identify common issues, there are times when it’s best to call a professional HVAC contractor. If you’re unsure about the problem or feel uncomfortable attempting to repair it yourself, it’s always best to seek professional help.
Additionally, if you notice any of the following signs, it’s time to call a professional:
- Your heating system is not turning on or is not producing hot air
- Your energy bills are increasing despite regular maintenance
- You notice unusual noises or smells coming from your system
- Your system is leaking water or refrigerant
- You’re experiencing frequent breakdowns or repairs
A professional HVAC contractor can provide a proper diagnosis, repair, replacement, and maintenance to ensure your heating system runs efficiently and effectively. They can also help you choose the right HVAC system for your home and provide guidance on maintaining it properly.
