Are you having trouble with your HVAC systems? Don’t worry! Many people have similar problems with their HVAC systems. Here are the top 5 most common problems with residential HVAC systems:

1. Dirty Filters

Did you know that filters should be changed every 3 months? Most people do not realize this, and rarely, or even never, change the filters. However, once you remove the filter, you will understand why they should be changed frequently, as they accumulate dirt and grime. A dirty filter will decrease the lifespan of your unit and will worsen the quality of air in your household. To extend the lifespan of your HVAC systems, inspect your filter once a month for filth.

2. Strange Furnace Noises

Furnaces will normally make noise to show that they are working. However, if you notice your furnace is making a high-pitched whining sound, this can indicate a larger issue with your furnace. The strange sounds can indicate airflow issues, motor issues, or complete furnace malfunctions. If you are noticing that your furnace is making odd noises, contact your HVAC technician, so they can identify the problem.

3. Water Leaks

HVAC systems can leak water if something is wrong. While both furnaces and AC units have drain pipes, sometimes the pipes can get clogged or cracked. You can check out your systems by yourself to identify if the pipes have been clogged. A simple solution for clogged pipes is to pour bleach down the pipe. If you notice that your pipe is actually cracked, it’s important that you contact a reliable HVAC technician, so they can help you with the next steps.

4. Thermostat Malfunctions

If there is a problem with one of your HVAC systems, there is a high possibility that your thermostat has malfunctioned. It’s crucial to understand how to work your thermostat, so that you can identify if there is a problem with it. For instance, your thermostat might need a battery change, or it might need a manual temperature adjustment. If this is the case, you can easily fix the problem on your own. On the other hand, if you cannot identify the problem yourself, call your HVAC technician immediately.

5. Insufficient Maintenance

The final problem with residential HVAC systems might be that you have not completed enough maintenance on your machine. When you have a new HVAC system installed by an HVAC professional, that should not be the end of your relationship. It’s crucial that you continue to contact them for maintenance on your system. This is because many problems with your systems can be avoided if you take proper care of them and ensure that maintenance is completed. Proper maintenance will extend the lifespan of your HVAC systems and also reduce your energy bills.
