Why Isn’t Your Split System Heating the Unit?

A split system is an ideal system for offering warmth during cold months. But what if the HAVC system does not provide the warmth you expect? It's a common issue, and your unit may fail to heat effectively for several reasons. In this piece, we'll help you understand the reasons behind ineffective split performance and what to do.

Understanding Split System Heating

A split system transfers heat into your home through an indoor and outdoor unit. The outdoor unit absorbs heat from the outside air and transfers it inside, which is circulated through the indoor unit. Several parts help carry out this process, including the compressor, the refrigerant, and the coils, all of which must operate in alignment to generate heat.

Signs Your Split System Isn't Heating

Here are a few signs to look out for if your unit fails to heat effectively:

  • Your system expels cold air instead of warm air.
  • Rooms temperature fluctuates unexpectedly.
  • A sudden increase in your electricity bill could mean ineffective heating from your HVAC system.
  • Your system shuts off frequently.

Reasons Behind Inefficient Heating

There are several potential reasons why your unit isn't heating correctly:

  • Dirty air filters in your split system can affect the efficiency of the equipment.
  • Low refrigerant levels can cause your HVAC system to be unable to produce heat.
  • Dirt or snow accumulation can interfere with the outdoor unit.
  • If the thermostat is faulty or incorrectly set, your unit may not turn on or produce the desired heat.
  • Old HVAC systems naturally lose efficiency over time. You should consider replacing your unit if it is over 10 years old.

DIY Troubleshooting and Maintenance Tips

Before seeking professional help regarding your split system, here are some guidelines.

  • Check the thermostat: Switch it to 'heat' and ensure it is appropriately set.
  • Inspect and clean the filters: Filters often get plugged, which you can handle by cleaning or replacing.
  • Clear debris from the outdoor unit: Check for any blockages and clear them to enable airflow.
  • Check circuit breakers: A tripped breaker can sometimes inhibit your system from working.

Some of these tips may help solve minor problems. Always be cautious when handling your HVAC system, and seek professional assistance when unsure what to do.
