When you have one room that always seems to be the wrong temperature, you need to figure out what is causing the problem. With this issue, the problem can be simple or complex, which is why you need to spend some time looking into the different areas that can affect airflow to that room. With some additional information, you will be able to figure out why that one room is the wrong temperature throughout the year.

Vent Issues

Unfortunately, some of the smallest issues will cause the biggest problems. For example, the vents inside the room may be the cause of low or improper airflow, which makes the room the wrong temperature.

One problem that you can have is that the vent is not open all the way. This can happen after you clean the outside of the vent, especially if the slider for the vent is loose. To check this, you want to slide the small piece on the outside of the vent in both directions, so you can see what the vent looks like when it is open and closed.

Another issue is if your vent cover is pointing in the wrong direction. When this happens, the air will hit the wall and not flow into the room. To fix this issue, you simply remove the small screws, turn the vent cover around and put it back into place.

Leaking Seam

Some issues are not as easy to determine, because you cannot see the problem from inside the room. In many cases, the cause is leaking ductwork seams. When the seams are damaged, hot and cold air will not reach the room. Instead, the air leaks into the location of your ductwork such as your attic or crawlspace.

To identify this problem, you need to have an HVAC technician inspect your furnace, outside compressor and ductwork. Even if you believe the problem is with your ductwork, it is best to have a thorough investigation, because the problem could be much larger than you were anticipating.  

If the cause of your issue turns out to be a leaking seam, the technician can repair the problem by replacing loose or missing screws and then sealing the seams. The sealing process can be done by using high-quality ductwork tape, though the most reliable option is a mastic cover.

Mastic is a malleable material that the technician spreads over the seam to close up the gaps within your ductwork. This product also prevents the seams from breaking again, because it allows the ductwork to expand and contract when hot or cold air flows through the system.

When one room always seems to be the wrong temperature, you want to find out what is causing the problem. You need to start by making sure that simple vent issues are not responsible for the problem. After you look into the smaller issues, it is best to consult an HVAC company, so a technician can evaluate your situation and then help you repair any problems that they find.
