Do you or someone in your household suffer from dust or mold allergies? If so, then minimizing the amount of both in the house is vital to ensuring comfort and health. Unfortunately, your HVAC can be the cause of many of these allergies. If you live in a humid or moist climate, mold issues can be especially bad. The following tips can help you avoid these problems.
Tip #1: Filter your air
It's common knowledge that AC and furnace filters need to be changed every one to two months. What you may not be aware of is which filter to use. If you have allergy issues, switch to a HEPA filter, which has smaller openings that allow less dust and spores through. Due to the tighter weave of these filters, they can become blocked more readily, so changing them monthly is a must. For further filtration of the air, you can also have an air purifier installed as part of the HVAC system. Cooled or heated air will pass through the purifier before entering your home, which will take out even more of the possible allergens so you won't have to breathe them.
Tip #2: Clean your ducts
Dust settles in air ducts, which when exposed to moisture, can quickly lead to mold growth. Then, when air comes through the ducts, all that mold and dust is forced into the air of your home where you and your family can breathe it. Since the air is exposed on the way into the room, it bypasses any filtration system, meaning the ducts are contaminating already filtered air. Having your ducts cleaned can stop this. An air duct cleaning company will use special vacuums and brushes to clean out all the ducts and registers in your home, as well as performing a full cleaning of the HVAC system itself.
Tip #3: Cut down on humidity
Humidity is what causes mold -- not just in ducts and filters, but also in other parts of your home. Installing a whole house dehumidifier can stop this. The less moisture in the air, the less mold and mold spores. If a whole house unit isn't an option, you should at least have a small free standing unit in the rooms where you sleep. This may not eliminate mold issues, but it can at least lessen them.
With proper maintenance and the right systems installed, you can minimize allergies and discomfort without compromising the ability to maintain a comfortable temperature in your home. Talk to a local HVAC service for more help.
