A List of the Most Common Problems with HVAC Systems – and What You Can Do to Resolve Them

Numerous households and businesses have an HVAC system, and these systems are one of the most expensive systems you can install for a home or building. And although you may encounter issues from time to time – the most common of which is the cleaning of the filters and coils – in general, your HVAC system shouldn’t give you too many problems throughout its lifetime. But the key is to have it checked and maintained regularly as well. Then, if there is a potential issue, you can address it before it becomes worse. But there are problems you can quickly identify and even fix. So what are these common issues? Here’s a list of the most common problems with HVAC systems – and what you can do to resolve them.

Not enough maintenance

Yes, this is a common problem with most HVAC systems out there. The thing is, the system can run and operate for a long time – but there may already be underlying problems that you don’t know about. If they aren’t fixed right away, they could cause your entire HVAC system to break down. To avoid these problems, it is essential to have your system maintained by a licensed contractor – such as specialists in air conditioner repair in Bartlett IL, like McNally’s. They will ensure that your HVAC system is in proper working order, and if there is a potential problem, it will be addressed immediately before it becomes a major issue. Also, it’s just good sense to have your system maintained – it will be as efficient as possible, it will have the best performance, and since it works well, your energy bills don’t have to shoot up!

Filters that are dirty

Another common issue with many HVAC systems is dirty filters. Regularly replacing your system’s filters is imperative; doing so can increase its lifespan and efficiency. If the system has dirty filters, it can block the flow of air, which means your HVAC system will work doubly hard to circulate the air. This, in turn, would strain the blower on your furnace, which can also cause issues with comfort. Aside from this, dirty filters can cause overheating and result in your system shutting off because it has reached its limit.

A malfunctioning thermostat

There are different kinds of thermostats available – mainly non-programmable and programmable. If your furnace is not working well, it could be a thermostat issue, so you have to check if it’s set correctly. Check the manual and find out if you are following the instructions carefully – this could help you save on unnecessary or costly service calls. Also, remember that if you have a programmable thermostat, you need to have the batteries changed once in a while. If the thermostat still has problems, even if you’ve changed the battery, it’s time to call in a technician.

Ignition issues

There could also be ignition issues, which can be caused by several things – a dirty flame sensor or pilot, faulty burners, a lockout of your furnace, or burners with a delay in the ignition. You could also have a problem with the gas supply or need to replace your thermocouple or hot surface ignitor. Whatever it is, it is best to have it checked by a technician, especially since you’re dealing with high voltages and natural gas.
