Your HVAC unit running non stop will undoubtedly leave you scratching your head because you know it’s not right. The unit running continuously puts a huge strain on the components, increases the risk of sudden breakdown – and shortens your equipment’s lifespan.
(Not to mention, it makes the system’s efficiency irrelevant.)
With every day that passes, you’ll lose a LOT of money – so, what can you do in this scenario? It depends on the cause of the problem. We’ll look at the various reasons your HVAC system runs without stopping and what you can do about each one.
Thermostat Problems
A malfunctioning thermostat is one of the most common reasons your HVAC system will run without stopping. It may be reading the temperatures wrong due to an internal malfunction, wrong programming or because of poor placement.
Check the thermostat to ensure you’ve entered the right settings. If necessary, reset the system and start over.
If that doesn’t fix the problem, consider moving the thermostat to a more central location where it’s not in direct contact with drafts, sunlight or other heat sources.
Dirty Air Filters
Clogged HVAC filters will cause the system to work harder to deliver hot or cool air.
Thankfully, this is an easy fix.
Replace the filter if it’s dirty and your system should go back to normal. Ideally, you should clean or replace your HVAC filters every month to ensure consistent airflow, efficient performance and healthy indoor air quality.
Refrigerant Leaks
Low refrigerant levels will leave your HVAC system running non-stop as it has to work harder to complete the heat transfer process.
Some confirmatory signs of refrigerant leaks include ice buildup on the refrigerant lines and hissing sounds while the system is in use. However, there’s no DIY fix here. You’ll have to call an HVAC technician to deal with the leak.
Electronic Control Board Issues
The electronic control board on an HVAC system controls all the processes that deliver your conditioned air. Certain issues in the circuitry can throw the configurations off balance, causing your system to run non-stop.
Control board issues are highly complex, and you have to call an HVAC technician who will test the board and recommend a replacement if necessary.
Poor Equipment Sizing
Have you noticed your HVAC system running non-stop almost from the first day of installation? There’s a high chance that you have a system that is too small for your space and is not powerful enough to reach your desired temperatures.
The only solution here is to call a professional HVAC technician to recommend and install an accurately sized unit for your home (hopefully, you’re still within your warranty window!).
