Maintaining Your Heating and Air Conditioning Units

Hello. My name is Max. My wife and I have five children who all live at with us in our large two-story house. My wife and two of our kids suffer from severe allergies which means keeping our home as dust-free as possible. I have learned that it’s crucial to keep our heating and air conditioning units properly maintained at all times. We have a fantastic HVAC company that comes out two times a year to perform routine maintenance on our system. They have taught me what I can do on a monthly basis in order to not only help with my family’s health but also keep our system running efficiently. I would like to share some of the tips I’ve been given. I hope you find this to be useful!

How To Troubleshoot A Ventilation Blockage

Kristin Pierce

If you have been having problems with your heater or air conditioner lately, then the source of your frustration might actually be your ventilation system. Here are some tips for diagnosing and handling one common problem with your ventilation system:

Do You Suspect a Blockage?

One of the most common problems that you might face is the simple blockage. If something is in your air ducts and prevents air from effectively moving to its destination, then your heater and/or air conditioner might seem like it is not working at all.

Check Each Room's Vent Cover

In order to test this theory, you should check every room to see how many are actually affected. If the blockage is sufficiently large, it should prevent certain rooms from getting any hot/cold air at all. Manually check every vent cover to see if you can feel noticeable air flow.

If you can't feel air moving, then you can test the situation even further by turning on the air conditioner or heater for 20-30 minutes. This method works best if you also close as many windows and doors as possible before proceeding. This will create a contained environment in each room, allowing you to easily tell the differences between rooms.

Finding the Blockage

Once you have actually identified the rooms that aren't getting air from the ventilation system, you want to develop an idea of where the blockage actually lies. If only one room is affected, then you can conclude that the blockage is somewhere in the air ducts between that room and the closest fork leading to other rooms. If multiple rooms are affected, the same principle applies and the blockage should be before the fork that leads to all those rooms, but after forks leading to other areas of the house.

Handling the Blockage

Cases where a single room is affected are often the easiest to handle on your own, since it means that the blockage might be easily accessible from the vent cover. A broom or vacuum with a hose might be long enough to reach such a blockage, which means that you can remove the blockage entirely on your own.

On the other hand, if multiple rooms are affected and the blockage is deep within your ventilation system, then you might have trouble getting to the blockage on your own. In these cases, hiring a professional vent cleaning service or HVAC contractor like Nebraska Heating & Air can be safer and quicker than trying to get deep into your air ducts on your own.
