A malfunctioning HVAC unit can be a huge inconvenience, especially if it stops working in the middle of summer or winter when you need it most. If you find yourself in this situation, don’t panic. There are a few things you can try to help resolve the problem. In this article, we will discuss the steps you need to take when you first notice a problem with your HVAC unit.
Check the Power Source
First, you need to check your system’s power source. Inspect your unit’s power source to ensure it hasn’t been accidentally unplugged or damaged. You may be able to get your unit to resume heating and cooling by simply plugging it back in. However, if you notice any electrical damage from rodents or pests, you will need to schedule a service call with your local HVAC technician ASAP. Not only does electrical damage wreck havoc on your HVAC system, but can be a fire hazard, so make sure to act fast in this situation.
Inspect Around the Unit
If you’ve confirmed that your HVAC unit has power, it’s time to look around the unit for signs of a problem. HVAC units are often subject to debris and weather impacts. Storms and high winds can cause yard items and tree branches to land on your unit and cause damage. In some cases, damage from debris is the reason for a malfunctioning HVAC unit. To resolve this, you will need to remove visible debris and schedule a service call with your HVAC technician who will be able to thoroughly inspect the unit and assess the severity of damage. One way to prevent this from happening is by securing yard items like furniture and toys before storms so they pose less of a risk to your unit.
Check the Thermostat
Another common culprit of a malfunctioning HVAC unit is the thermostat. If your HVAC unit has power and is free of damage from debris, the next thing to inspect is the thermostat. HVAC thermostats can be tricky to operate, particularly if your thermostat is outdated. This is one of the reasons why we recommend investing in a programmable thermostat that can be more easily controlled. When checking your thermostat, you’ll want to adjust the setting and listen for the sound of air moving through your duct work. You can also place your hand over a vent to feel for air flow. If you don’t hear or feel airflow, then it’s time to have a service call with an HVAC professional.
Reset the Unit
In some cases, your HVAC unit may need to be reset to begin working again. To do this, you will need to flip the breaker that powers your HVAC and then find the reset button on your unit. Most modern HVAC units have a reset button, but you’ll need to look around your unit to locate the right button. Once reset, check to see if the unit turns on. If you notice the HVAC unit has power, try adjusting the thermostat to test for airflow. Airflow may be restored after the reset, but if not, you will need to contact a professional to further inspect the unit.
Schedule a Service Call
When in doubt, contact your local HVAC company. These professionals are trained to quickly diagnose and resolve any problems with HVAC systems. A malfunctioning HVAC unit can be a huge inconvenience, and it’s important that your home is as comfortable as possible. So, if your unit stops working or shows signs of a problem, make sure to schedule an appointment with a professional. While there are plenty of DIY repair videos online, it’s best to leave major servicing to the experts.
