How to Fix Issues with your HVAC System: Heat Keeps Running

Feb 12, 2024

Welcome to Proflo HVAC Contractors! We are here to provide you with valuable information on how to fix common issues with your HVAC system, specifically when the heat keeps running. As experts in the field, we understand the importance of maintaining a comfortable and energy-efficient commercial or residential space.

Understanding the Issue

One of the most common issues faced by HVAC system owners is when the heat keeps running non-stop. This can lead to discomfort, high energy bills, and potential damage to the system if left untreated. To tackle this problem, it's essential to identify the underlying causes and implement the right solutions.

Possible Causes

Several factors can contribute to the continuous operation of your heating system. Here are a few potential causes to consider:

  1. Thermostat Malfunction: A faulty thermostat can fail to properly communicate with the HVAC system, causing it to continuously provide heat.
  2. Clogged Air Filters: Dirty or clogged air filters restrict airflow, leading to overheating and the constant operation of the heating system.
  3. Leaky Ductwork: Holes or leaks in your ductwork can cause heat loss. As a result, the system compensates by running continuously to reach the desired temperature.
  4. Blocked Vents: Obstructed vents prevent warm air from circulating effectively, resulting in the heating system working overtime.
  5. Faulty Zone Control System: If you have a zone control system, a malfunctioning zone valve can cause the heating system to continuously operate in specific areas of your space.
  6. Faulty Pressure Switch: A faulty pressure switch fails to detect pressure changes, leading to the constant operation of the heating system.

Solutions for Addressing the Issue

Now that we understand the potential causes, let's explore the possible solutions to fix the issue when your heat keeps running:

1. Check and Calibrate Your Thermostat

Start by ensuring that your thermostat is functioning correctly. Replace the batteries if necessary and check the programming to ensure it's set to the desired temperature. If you suspect a thermostat malfunction, consider contacting a professional HVAC contractor to evaluate and repair or replace the thermostat.

2. Replace Air Filters Regularly

Dirty air filters can cause various HVAC system problems, including continuous operation. Regularly inspect and change your air filters according to the manufacturer's recommendations. This simple step can greatly improve the efficiency and lifespan of your heating system.

3. Inspect and Seal Ductwork

Inspect your ductwork for any visible holes or leaks. Sealing these leaks promotes energy efficiency and prevents the heating system from overworking. You can use specialized duct tape or consult a professional contractor for more advanced duct sealing techniques.

4. Ensure Vents Are Unobstructed

Walk through your space to check if any vents are blocked by furniture, curtains, or other objects. Clear any obstructions to allow proper airflow and efficient heat distribution, ensuring your HVAC system doesn't need to work harder than necessary.

5. Verify Zone Control System Functionality

If your property is equipped with a zone control system, evaluate each zone's functionality. Check for any malfunctioning zone valves and replace them if needed. A well-functioning zone control system will optimize your heating system's efficiency and help prevent continuous operation.

6. Test and Replace Faulty Pressure Switch

If you suspect a faulty pressure switch, consult a professional HVAC technician to diagnose and replace it if necessary. This component plays a crucial role in maintaining the proper operation of your heating system.

Maintaining a Healthy HVAC System

Prevention is key to ensuring your HVAC system operates optimally. Here are some additional tips for maintaining a healthy system:

  • Regular Maintenance: Schedule annual maintenance visits with a professional HVAC contractor to inspect and service your system.
  • Proper Ventilation: Keep all vents clean and unobstructed to maintain good airflow throughout your space.
  • Regular Filter Changes: Replace air filters as recommended by the manufacturer to prevent clogs and maintain efficient operation.
  • Temperature Adjustments: Make gradual temperature adjustments to avoid putting unnecessary strain on your HVAC system.
  • Timely Repairs: Address any HVAC system issues promptly to prevent small problems from escalating into more significant and costly repairs.

In Conclusion

When faced with the issue of your heat keeps running, it's essential to take the appropriate steps to identify and address the underlying causes.
