When it comes to HVAC systems, many different issues can arise. It is important to be aware of these issues so that you can take steps to prevent and troubleshoot them. Having a well-ventilated space is extremely important, so it is really important to maintain your HVAC system all year round, as this website explains.
However, sometimes issues happen regardless of how well you look after your system. In this article, we look at the most common HVAC problems, and how to fix them. Sometimes, you can fix things yourself, especially if it is just a case of cleaning. However, more often than not, you will need to call in the help of an experienced professional.
In order to diagnose and fix heating, ventilation, and air conditioning problems, you will need to inspect various aspects of your system. An HVAC unit contains an air conditioner, ductwork, a furnace, and a fan. All of these can have individual issues and need to be addressed carefully.
How to Troubleshoot Your HVAC
To start with, check that your HVAC unit has power. Ensure that the circuit breaker has not tripped, and try turning it off, waiting for 10-15 seconds, and then switching it off. Also, look to see if you have a broken, blown, or burnt fuse. Finally, check the thermostat. Often, thermostats can break, and this will prevent the whole system from operating. If it is not working, you will need to order a new one. If everything looks to be in working order you can move on.
Next, you will want to check the furnace. Turn the thermostat to heat mode and check to see if heat is coming out. If it is not working, reset the furnace. This is usually done by opening a small door and clicking on the ‘reset’ button. If anything seems a little off or you think there is a problem with the ignition, you will need to call in a professional to help.
If everything is working with the furnace, try checking the filters. Often, dirty filters can be the cause of malfunctioning HVAC systems. If your filter is clogged it will restrict the free airflow, putting a strain on the blower. If it does look dirty when you check it, you need to replace it immediately.
You should be replacing your filter regularly anyway, approximately every 90 days. You can usually do this yourself but if you need to, a professional will be able to help change the air filter for you. There are so many types of air filters out there, and you will need to find out the right one for your specific HVAC system. Read more about understanding HVAC filter selection here.
Once you have checked that your air filter does not need replacing, it is also worth checking your coil. Like the air filter, this can become blocked and dirty, reducing the efficiency of the HVAC system. You can clean this yourself but if it looks particularly bad, it will need to be cleaned by a trained professional.
Likewise, if you can check the ductwork, ensure that it is in good condition, not dirty or clogged and that there are no punctures. Any signs of damage could indicate that air is not flowing properly and may need replacing.
Another element of your HVAC to check for damage is the blower fan. The blower fan helps to move air through the ductwork. If this is damaged it will stop the whole HVAC system from operating. If this does not seem to be working, you are best to call an HVAC technician to diagnose whether it is a failing fan motor or a build-up of dirt on the fan. These are both relatively easy to fix and should be quick to resolve.
Finally, blocked air vents can stop HVAC systems from working efficiently. Walk around your house or space and make sure that the vents are not being covered by any furniture, plants, or blankets. The vents need to have space to breathe. If the vents look damaged you might need to have them replaced altogether.
If your HVAC is making strange noises such as hissing or whistling, it is usually a sign that something has malfunctioned. If you hear a noise that doesn’t sound right, it is normally best to call a technician straight away rather than go looking to fix the problem yourself.
If you are unsure on what to do or concerned about something strange, it is always best to call in the help of a professional HVAC servicing company to diagnose any major issues and service your system. Of course, they will be the best go to so problems can be fixed the fastest way.
So, there you have it, if you are having trouble with your HVAC system there are things you can do yourself to troubleshoot the issue.
