5 Signs Your Windows Are Letting Summer Heat Into Your Charlotte Home<\/h1>\n\n\n\n

Living in Charlotte in the summer means high temperatures, high humidity, and long afternoons with an intense sun. Those conditions can put your home to the test. In fact, you might notice that certain rooms in your home suddenly become uncomfortable. The second level of your house may feel much warmer, rooms with west-facing windows may take forever to cool down, or your air conditioner may seem to run constantly.<\/p>\n\n\n\n

Many people initially assume their AC is the problem, but realistically, your windows may play a bigger role than you realize. Here are five signs that your windows may be letting excessive summer heat in your home.<\/p>\n\n\n\n

1. Certain rooms feel hotter than others<\/h2>\n\n\n\n

Is there one bedroom in your house that runs hot? Or is your upstairs uncomfortable even if the thermostat indicates that the temperature is where you want it to be?<\/p>\n\n\n\n

This is one of the most prominent signs that something is wrong. Rooms with west-facing windows experience greater heat buildup because of the afternoon sun. The same can be said if that room has older windows. In homes in Charlotte, that afternoon sun can have an especially significant effect during the summer.<\/p>\n\n\n\n

Some temperature variation in your home is normal, but a significant difference from room to room can point to inefficient windows that allow too much heat inside. Replacement windows in Charlotte<\/a> can be part of the solution.<\/p>\n\n\n\n

2. Your AC runs constantly<\/h2>\n\n\n\n

If it seems like your cooling system never catches a break, your windows could be contributing to the problem. <\/p>\n\n\n\n

Older windows can allow heat into your home more easily than modern energy-efficient windows. This forces your HVAC to work harder than it needs to in order to maintain a comfortable temperature inside. When that happens, your energy bill rises. <\/p>\n\n\n\n

Replacement windows<\/a> that feature modern glass packages and improved insulation can help reduce that unwanted heat gain.<\/p>\n\n\n\n

3. You feel heat when standing near windows<\/h2>\n\n\n\n
    <\/ol>\n\n\n\n

    This is something simple you can test. During the hottest part of the afternoon, go stand near one of your windows. Do you feel a noticeable increase in warmth coming from that area? <\/p>\n\n\n\n

    A window shouldn\u2019t feel like a heater inside your home. If you notice a difference near the glass, it could indicate that the window isn\u2019t doing a good job of blocking the heat transfer. <\/p>\n\n\n\n

    4. Your furniture or floors seem to be fading<\/h2>\n\n\n\n
      <\/ol>\n\n\n\n

      Ultraviolet (UV) rays have the ability to gradually fade hardwood flooring, furniture, rugs, curtains, and even artwork. <\/p>\n\n\n\n

      Modern vinyl window options<\/a> typically include technology that reduces UV exposure while still allowing natural light to filter into your home. <\/p>\n\n\n\n

      Pull up the corner of a rug. Can you see a difference in the coloring of your wood floor? That can be a sign that your current windows aren\u2019t providing the protection they should.<\/p>\n\n\n\n

      5. You have older windows<\/h2>\n\n\n\n
        <\/ol>\n\n\n\n

        You probably know that window performance declines gradually rather than all at once. In fact, you can live with inefficient windows for years without even noticing it. <\/p>\n\n\n\n
