How Humidity Effects Your Home

imageWhen your air conditioner is running, it’s not just cooling down your home; it is lowering humidity levels as well. That’s because when heat is removed from air moisture is released in the form of condensation. So if something goes wrong with your air conditioner, your home’s humidity levels can get too high and cause all kinds of issues. Today we’re going to talk about the effects of high humidity levels at home and what you can do to ensure your air conditioner can effectively remove moisture from the air!

The effects of high humidity at home Comfort and efficiency issues. When humidity levels are high, homes tend to feel warmer than they actually are. As a result, many people lower their thermostat settings to compensate for the uncomfortable environment. This is a waste of energy because your air conditioner will have to work harder to make your home feel comfortable.
Unhealthy air. Airborne contaminants like bacteria, viruses and dust mites tend to thrive in areas of high humidity. Not only does this increase the likelihood of people in your home getting sick, but it also makes symptoms worse for people who suffer from asthma or allergies.
Excess condensation. High humidity means there is excess moisture in the air. This tends to be most visible on your windows where you can see condensation dripping down the glass. If this happens for a prolonged period of time, it can damage wooden frames and nearby walls.
Damage to furniture. When there is a lot of moisture in the air, wooden furniture can get damp and stained. In severe cases, this can cause permanent damage.
Damage to musical instruments. Humidity can be a huge problem for instruments that are made of wood, such as guitars and violins. The moisture in the air causes the wood to swell, which can cause glue joints to fail, finish to lift, and neck angles to go bad.
Spoiled food. Certain foods can go bad quickly if humidity levels are high. This is most problematic for food that you would normally store in a cabinet or on the counter, such as bread and starchy vegetables.
Keep humidity levels under control by taking care of your air conditioner

The best way to ensure that humidity levels stay under control during summer is to take good care of your air conditioner. If your air conditioner is dirty, experiencing operational issues or having problems with the condensate line, it will not be able to remove moisture as effectively as it should. By scheduling annual tune-ups and regularly changing your air filter, you can greatly help avoid problems like these and keep your home’s humidity at the right levels.

Turning off my air conditioner?

If you talk to your friends or search around the Internet, it seems like everyone has a different opinion about what you should do with your air conditioner when you’re away from home. Is it a good idea to shut off your system completely or should you raise your thermostat setting instead? Also, what should be done with your air conditioner during severe weather? Today we’re going to offer our expert opinion on these issues by answering the question, “Should I ever turn off my air conditioner?”

Should I turn off my air conditioner when I leave for work?

First, we’ll address the most common situation in this debate. Many homes are unoccupied during the weekdays when family members are at work or school. Can you save energy by turning off your air conditioner during those hours?

Of course you can save energy by shutting off your air conditioner, because your system won’t consume energy when it’s not being used. The problem arises when you get home and turn your air conditioner back on. If you leave your system off throughout the day, temperature levels in your home will consistently rise. Temperatures will get so high, in fact, that the amount of energy it takes to cool your home back down to a comfortable level will cancel out any energy that you saved by leaving your system off.

In addition to efficiency issues, there are other side effects of turning off your A/C during the day. If you have pets, for example, it might be unsafe for them to be left alone in the heat during the day. Also, the last thing you want during a hard day at work is to come home to a hot and humid home. You might have to wait a few hours before your home cools back down a comfortable level.

Instead of turning off your air conditioner when you leave for work, we suggest raising your normal thermostat setting by about 2-3 degrees to save energy while you’re away.

Should I turn off my air conditioner when I go on vacation?

Many people consider shutting off their air conditioners before they leave for vacation. Not only will this amplify the problems listed above, but it can also lead to even more serious issues.

By leaving off your air conditioner for days at a time, nothing will be done to control humidity levels inside your home. If humidity levels are high for an extended period of time, wooden furniture can warp, paint and wallpaper can peel, condensation can stain your walls and ceilings and your home can develop a musty smell.

Another issue with leaving your air conditioner off during vacation is that your refrigerator will have to work extremely hard because the area surrounding it will be hot. Not only will this increase your energy bills, but it can also damage your refrigerator or cause it to leak water.

Instead of turning off your air conditioner before you leave for vacation, we suggest setting your thermostat to around 78-80 degrees.

Should I turn off my air conditioner during a storm?

Air conditioners are built to withstand the elements outside, so you should not be concerned with running your system when it’s rainy or windy.

The only time you might consider turning off your air conditioner is when there is a lot of lightning nearby. Shutting off your system may help protect your system from a power surge, but you should be sure to turn your system back on as soon as the storm passes. Better yet, ask 3D Air Services about installing a surge protector for your air conditioner and furnace. A surge protector will protect your heating and cooling system from power surges so that you truly never have to worry about shutting it off.
