Why the Upstairs of Your Home Is Hotter Than the Downstairs

Posted on

If you have a home that has multiple stories, one of the challenges you might face is that some areas of your home are hotter than others. This may make the upstairs of your home intolerable. Fortunately, there are ways that you can correct this problem. 

You May Need to Replace Your AC

One of the common reasons why your upstairs may be hotter is that you've waited too long before replacing your air conditioning unit (AC). An air conditioner typically lasts fifteen to twenty years. Each year that passes, your air conditioner becomes less efficient. Your upstairs might be too hot because your air conditioner just can't keep up anymore. Before you spend money to have your air conditioner replaced, you should have it fully inspected by an HVAC (heating, ventilation, and air conditioning) technician. You may have a part that has worn down and broken. 

Your AC May Have Never Been Strong Enough

If your air conditioner has always failed to keep the upstairs cool enough, it may not be powerful enough. You may need a larger air conditioner that is capable of cooling a building with as many rooms as you have. If the original installers of your air conditioning unit did not perform proper measurements, your HVAC system will not be large enough.

You Don't Have Enough Insulation

Your attic can easily fill with very heated air. If you do not have an attic that is properly insulated, the heat in your attic can flow to the rooms below. Proper insulation will keep hot air in your attic during the summer and will prevent hot air from escaping your home through the roof in the winter. For this reason, you should make sure that your home has adequate insulation.

Your Air Ducts Are Leaking

The further that your air conditioner is from the second floor, the longer the air ducts need to be. If there are any leaks in your ducts, the AC simply may not be able to deliver the cooled air to wherever it needs to go.

If you discover leaks in your air duct, you may be able to fix them. However, you will likely only find leaks in the accessible parts of your air duct system. You will not find air leaks in the sections of your air ducts that aren't accessible, and you may not even be able to discover these leaks without a qualified HVAC technician.
