How to Know if Your HVAC Problem is Normal or Not

How to Know if Your HVAC Problem is Normal or NotMany homeowners don’t know much about the day-to-day life of their HVAC systems. As a result, they’re likely to make a service call when they encounter any issues with their systems. Some HVAC problems are easy to solve on your own. And you know what? Some of these issues are not even problems in the first place. Keep reading to find out if the issue you’re facing is typical or an actual problem.


If your HVAC system is working properly, it should emit little to no smell or odor. However, your furnace produces a slight odor when you use it for the first time at the beginning of the winter. That’s because it’s naturally burning off the dust that collected in it during the long period it was not in use. The smell will go away after the first few times your heating system turns on.

If you detect a musty smell, that’s a sign of mold buildup on or in your HVAC system. A burning or electrical smell could be a sign of a system that’s overheated, a melting wire, or a dirty air filter.

Water Leaks

Regular condensation occurs naturally during the normal operation of an HVAC system. Your unit may produce water on it coils or exterior parts. Therefore, don’t panic if you see a little water around or on your system.

On the contrary, a lot of water leaking from your air conditioner, furnace, or system component shows there’s something that’s draining incorrectly, dripping, or has developed a leak.


If your HVAC system is working properly without any problems, it will be quiet with occasional whooshing of air that can be heard throughout your home.

However, clanking, rattling, or banging noises are a sign of a clogged vent or loose components.

Now that you know what’s normal for your HVAC system, you can avoid paying for service that’s not necessary. If what you’re experiencing isn’t normal, have it fixed quickly to prevent the problem becoming bigger and costlier. To learn more about HVAC problems, contact Cool Power.
