Your HVAC system works hard all-year-round to improve the air quality in your home and keep indoor humidity at an acceptable level. However, like other appliances you use in your home, your HVAC will break down at some point and require repairs.
Dealing with a malfunctioning HVAC system, more so in the middle of summer or winter is no fun, but it does happen. That being said, having knowledge of the most common HVAC problems and how to troubleshoot your HVAC will help you keep your unit running smoothly.
If your HVAC unit is acting up or has suddenly stopped working, there are some things you can do before deciding to call a professional HVAC company for AC repair.
Here are a few places to start:
Sometimes, the simple reason why your HVAC is not running is because power is off. Start by checking if the unit is plugged in or if the breaker has tripped due to a power surge. If the breaker tripped, you’ll only need to flip the breaker to get your HVAC up and running again.
A power problem can also be caused by a faulty outlet, so you’ll also need to check if the outlet where the AC power cord is plugged in is working.
A faulty thermostat can cause your HVAC unit to run continuously and fail to turn off when the desired temperature is reached. To troubleshoot your thermostat, start by making sure that it has power. If it’s battery-operated, try changing the batteries.
You’ll also need to test the settings to ensure they’re correct and clean the thermostat if there is any dust and debris within the thermostat housing.
The thermostat can fail as a result of wiring problems, but you should not try to fix wiring connections if you’re not a certified and licensed HVAC repair expert.
Air vents are a vital component of your HVAC system and serve several purposes. The vents can get obstructed by dirt, dust, or foreign objects and obstruct the flow of air. If you notice irregular air flow in your home, the problem could be obstructed vents. Make sure you check the vents, ducts, and grills for blockage.
Over time, the air filter may get clogged, causing your HVAC unit to overheat. You’ll know your HVAC’s air filter is clogged if you experience allergy symptoms, low airflow, and increased utility costs. Before you can call an HVAC specialist, be sure to check if the air filter is in good working condition.
Although many homeowners overlook the outside unit when troubleshooting their HVAC systems, it’s important to ensure there’s no dirt or debris on the surface which could obstruct air flow.
