Reasons Why Your HVAC May Not Be Working

When your HVAC system works the way you expect it to, you probably don’t think much about it. But when something goes wrong, it can be stressful, leaving you to wonder, “Why isn’t my HVAC system working?”

Suburban HVAC is the leading HVAC company in Westwood, MA, offering expert residential and commercial HVAC services. We understand the importance of diagnosing HVAC problems promptly. Here, we’ll discuss the top reasons your HVAC system isn’t working.

Thermostat Troubles

Sometimes, the problem with your HVAC system is as simple as an issue with the thermostat. Your system may not work correctly if the thermostat is set incorrectly or isn’t well-calibrated. For example, if it’s set to the wrong temperature or mode, your HVAC system may not turn on or could be cooling instead of heating.

Sometimes, a malfunctioning thermostat can cause your system to turn on and off too frequently or stop. If adjusting the settings doesn’t solve the problem, it might be time for a thermostat repair or replacement.

Airflow Restrictions

Restricted airflow is another reason HVAC systems break down. If your system doesn’t get enough air, it will overwork itself, resulting in poor performance and higher energy use. Clogged air filters are one of the most common causes of restricted airflow. Filters can become packed with dust, dirt, and debris, blocking the flow of air into the system.

Blocked vents or ducts also lower airflow. If furniture, curtains, or other objects are in front of the vents, your system may struggle to heat or cool your space. Debris in the ductwork can also block airflow. Regularly checking and cleaning your filters, vents, and ducts can help stop airflow issues.

Electrical Failures

Your HVAC system uses electrical components to run, and electrical failures can cause it to shut down. A tripped breaker or blown fuse could be the reason your system stops working. Wiring issues or problems with electrical parts can also cause your system to break down.

If you think your HVAC system has an electrical problem, it’s important to call a professional, as working with electrical components can be dangerous.

Refrigerant Issues

Refrigerant is another essential part of your HVAC system. It uses it to help cool your space. Low refrigerant levels or leaks will impact your system’s performance. If you notice that your system isn’t cooling well, is blowing warm air, or is taking longer to reach the desired temperature, it could be a refrigerant issue at the root of the problem.

Leaks can also damage your system if left too long. It’s important to have a professional find and fix the leak and recharge the refrigerant to restore your system’s efficiency.

Aging Equipment & Maintenance Neglect

As HVAC systems age, their components experience wear and tear. If your system is over 10 to 15 years old, it may be time to consider replacement, especially if you need more frequent repairs. Routine maintenance can extend the lifespan of your system and allow our technicians to find problems before they become big issues.

Neglecting routine maintenance can also lead to unexpected breakdowns. Dirty coils, worn-out belts, and old motors can make your system work harder, which reduces efficiency and increases the possibility of failure. Scheduling regular HVAC maintenance helps keep your system in top shape.
