What To Do When Your HVAC System Stops Working

Your HVAC system is one of the most important parts of your home. It keeps you and your family comfortable by regulating the temperature and air quality inside your home. However, like any unit, it can stop working without warning. This can be not only uncomfortable but also dangerous. Knowing how to handle the situation when it happens is crucial. In this blog post, we will discuss important steps to take when your HVAC system stops working.


1. Check the Thermostat

The first thing you should do is check your thermostat. Ensure it's in the "on" position and set at the right temperature. If the thermostat isn't working right, it might be the reason for the malfunctioning of your system. Try changing the batteries, and if it doesn't remedy the situation, then calling an HVAC professional should be your next step.

2. Inspect the Air Filter

A dirty or clogged air filter could be one of the reasons why your HVAC system is not working. An unclean filter suffocates your system, causing it to work harder than it needs to, overheating the motor, and reducing its efficiency. You should inspect and replace your filter every three months or as recommended by the manufacturer. If the units filter is visibly dirty or clogged, it’s time to replace it.

3. Check the Breaker

Check the electrical panel to see if the circuit breaker for your HVAC system has tripped. Typically, the breaker will trip when there's a power surge or overload. This is a safety feature, and if it's tripped, it won't let electricity flow through the circuit. Resetting the breaker could quickly solve the problem. If it keeps tripping, it might be time to call an HVAC professional to make an assessment.

4. Inspect the AC Unit

Go outside and take a look at your AC unit. Check to make sure there's no debris or anything blocking the airflow around it, and the fan is turning. If the fan isn't working or slow, the compressor could overheat and trip the safety overload. If this happens, turn off your AC and call an HVAC professional.

5. Call Professional HVAC Technician

If none of the steps outlined above solves your problem, it’s time to call an experienced and certified HVAC professional. Attempting more complex repairs or maintenance should not be taken by anyone inexperienced. The smart thing to do is to contact a licensed professional that knows how to diagnose and solve the problem correctly. It would save you time and also ensure your HVAC unit is working optimally.



Your HVAC system can be your savior during hot or cold months, but it can unexpectedly malfunction. In such situations, it's vital to act quickly and follow the necessary steps outlined in this blog post, like checking the thermostat, changing the air filter, checking the breaker, inspecting the AC unit, and contacting an HVAC professional if none of the steps above resolves the issue. Taking the necessary precautions will ensure your system is in good shape, running efficiently and effectively, keeping you and your family comfortable year-round. If you're looking for an HVAC supplier in Florida, contact Discount Air Supply today for more information.
