As temperatures rise, properly running heating, ventilation, and air conditioning (HVAC) systems are crucial. However, it can be frustrating if your system suddenly stops working or needs to run more efficiently. If your HVAC system isn’t working correctly, it can be difficult to determine the problem. To quickly identify the issue, there are a few key things you can look for.
1. Check the Thermostat
If your HVAC system is not working, the thermostat settings are the first place you should look at. If the thermostat settings are not appropriately set, it can cause the HVAC system to stop functioning. Ensure that you have set your thermostat to the proper temperature for cooling or heating. If you have set the temperature to your liking and it still isn’t working, verify that your thermostat is set to cooling or heating mode and doesn’t need a battery change. If this does not solve your problem, try setting the temperature a few degrees lower or higher than your set temperature. If the HVAC starts working, it indicates that the thermostat is faulty or outdated, and you should consider replacing it.
The thermostat location is critical to maintain the temperature in your house. If the thermostat is not placed in the correct position, it can lead to the HVAC system not working. Generally, the thermostat should be placed in the center of the house where it can quickly sense the temperature level. If it is placed in the right position, it can lead to correct temperature readings. Ensure your thermostat is not installed next to a window, door, or any other source of heat or cold air. The thermostat will pick up temperatures from nearby external sources and affect the HVAC system’s operations.
Thermostat wiring can cause HVAC systems to stop working suddenly. The wiring that connects the HVAC system and the thermostat undergoes wear and tear over time. As a result, it can cause the thermostat to lose connection with the system, causing your HVAC system to not work. You can check for wiring issues by turning off your thermostat, removing it from its wall mount, and inspecting the wires. Look for loose wires, broken connections, or any corrosion. It would help if you were cautious when working with wiring. It is recommended to contact a specialist regarding electricity.
2. Check the Air Filter
The air filter plays an essential role in the efficiency of your HVAC system and can cause it to malfunction if it is not changed regularly. An air filter prevents dust, dirt, pollen, smoke, and other particles from entering the HVAC system. If the filter is too dirty or clogged with debris, it will reduce airflow in the system, causing it to run inefficiently and eventually break down. If you have been neglecting the air filter for a long time, it could be why your HVAC system is not working properly. You can check your air filter’s condition by removing and inspecting it. If you last changed your filter over three months ago, it’s time to replace it.
3. Check the Electrical Connections
If your HVAC is not turning on, the electrical connections may be the issue. Ensure wires are not corroded or loose, and check the breaker or fuse box to see if there was an overload or a blown fuse. If you do not have experience with electrical work, consider calling a professional to avoid any potential safety hazards.
4. Check the Outside Unit
If the outside unit is obstructed or dirty, it can compromise the functionality of your HVAC system. Remove any debris, trim any nearby vegetation, and clean any dirt or grime blocking airflow. You can also look into preventative maintenance services to ensure your outdoor unit stays clean and running smoothly.
5. Check for Refrigerant Leaks
Refrigerant is what cools the air in your HVAC system. If there is a leak, your HVAC will not work properly and could even damage the compressor. If you hear a hissing noise or notice ice on the outdoor unit, there may be a refrigerant leak. It’s important to call a professional to fix the leak and recharge the refrigerant properly.
