A central HVAC system does much more than just heat and cool the rooms. It is also part of the ventilation and filtering of the air. That is, central HVAC circulates stale air out of your rooms and filters new air before it pumps the air into your rooms. Basically, it has a lot to do with how your home will smell. Luckily, there are a few simple things that homeowners can do to improve the smell in their home. This article shows how you can check for the source of bad odors and how to best neutralize them.

Change the Filters

The first thing you should do, if you notice that the air in your home is odorous or stale, is to check the filters. The in-duct filters are easy to access and should be changed at least once a year. Most people don't change their filters this often, and so they commonly have ineffective filters. Even worse, the filter could have mold build up, which could be the cause of the smell. Mold usually forms due to moisture within the ducts. So, if your filters are dirty and moldy, you will want to have your entire duct system professionally cleaned to get all of the potential mold out.

A full scale, professional duct cleaning service might help you rid of other possible odor causing things. The worst case scenario, though not uncommon, is that there is a small rodent or bird that has died inside the ducts. This can be a serious issue, and the smell can be very overwhelming. Getting rid of the dead animal and having your ducts cleaned and sterilized should always be done by duct cleaning pros.

Service Your Air Pump

The air pump (or blower, depending on what type of system you have) is responsible for circulating the cooled or heated air into your ducts. So, even if your ducts and in-duct registers are clean, you could have odors stemming from the pump. Most pumps have a separate filter attached to the furnace unit. Make sure this filter is changed regularly and that there is no mold build up. Also take a close look at the actual fan blades and within the pump compartment. Moss or mold in here is going to end up in your rooms.

Usually, when you walk by your air pump, you will be able to tell if there is a strong odor. If so, you know this is where the problem is coming from. For more information, contact local professionals or visit sites like http://www.accontractorspringfieldmo.com/.
