The humidity levels in the area you live to play a big part in your HVAC system. Since one of the major purposes of an HVAC is to remove humidity from the air inside your home the amount of humidity present is important. When humidity is very high your air conditioner has to work harder. The older systems and any system of the wrong size will not be able to handle the humidity. The air in your home will feel a lot warmer than it actually is because of the humidity. There will be additional wear and tear place on your unit and it may break down. Your electric bill will also rise.
When your air conditioner is not properly cooling the air there is a good chance the problem is the level of humidity. Some of the more obvious signs include a moistness in the air, a musty odor, and foggy windows. A dehumidifier can help pull excess moisture from the air before it enters your ducts. In the summer your humidity level should not exceed sixty per cent. To work properly a dehumidified should be installed professionally directly onto your current system. This will allow you to manage the temperature inside of your home to suit your comfort level.
In the winter humidity is also a problem since cold air is not capable of holding onto humidity nearly as well as warm air. A lack of humidity will make your home feel colder than the actual temperature. This can cause a variety of health-related issues such as dry nasal passages and skin, irritations in the eyes and sinus problems. Your HVAC may use excess amounts of energy and still leave you feeling cold. A dehumidifier can also be used to add moisture to your air.
The maintenance of any equipment you have outside is just as important as what is inside your home. Heavy humidity will affect your condenser. Dust, dirt and different types of debris can build up in your systems fins and coils. Having your condenser professionally cleaned will lower your energy bills and prevent excess wear on your unit. Misting the unit yourself with a garden hose between maintenance will cool the air that goes through the condenser coils. This will let your unit absorb more heat and the temperature of your home will be easier to maintain. The effect this will generate is similar to a cool breeze on sweaty skin. Once the dirt and debris are removed your unit will again be able to function at full efficiency.
