Owning a heating, ventilation and air conditioning (HVAC) system is a big responsibility. When something goes wrong, it can be difficult to know whether you should try to fix it yourself or call in a professional.
There are many things that can go wrong with your HVAC system, but some of them are easier to fix than others. In this article, we’ll take a look at some of the most common HVAC problems and how to fix them.
1. Strange Sounds
If you hear screeching noises, squealing, buzzing, or rattling from your HVAC system, there may be a problem with one of its components. This could be as simple as a dirty air filter, but it can also mean that there is a loose part, or that the fan blades are out of balance. It’s important to have any odd sounds from your HVAC system looked at by a professional to avoid expensive repairs.
2. Thermostat Issues
If your HVAC system is turning on at the wrong times or not turning on at all, it might be time to replace the thermostat. A faulty thermostat can lead to all sorts of other issues with your system, from overheating to a steep electricity bill. To fix the issue, first check to make sure that the thermostat is getting power by flipping the breaker. Next, check to see if the batteries have changed or that the settings have been changed.
3. Wiring Problems
Many HVAC problems stem from wiring issues, including fraying, corrosion, or disconnection. If you’re experiencing any of these issues, it’s important to contact a professional immediately as they can be very dangerous for your system. It’s also important to schedule routine maintenance with a trusted HVAC technician every quarter, so they can clean out and tighten all of the system’s components.
4. Compressor Issues
Your compressor is one of the most costly parts of your HVAC system, so it’s important to maintain it properly. Typical problems with the compressor include a lack of refrigerant, a damaged condenser fan, or an overheating motor.
5. Ignition Problems
If you’re noticing that your heating or cooling isn’t working as well, it might be time to change the pilot light or igniter. These are the components that turn the system on and off, so if they’re not working properly, it can significantly affect your home or business.
While there are a number of different problems that can cause an HVAC unit to stop working, some of them are more serious than others. High energy bills, odd sounds, and a lack of heat are all signs that you need to contact a professional right away. If you follow the advice in this article, however, you should be able to fix most of the issues without having to call in a professional.
