Allergy season is almost here. If you suffer from allergies or asthma, indoor air pollution can trigger your symptoms. Yet there are some simple HVAC maintenance steps you can do to improve the cleanliness of the air in your home.
According to the EPA indoor air pollution can range anywhere from two to as much as one hundred times more polluted than outdoor air. This is of big concern since people spend as much as 90% of their time indoors. Exposure to poor quality indoor air leads to increased health problems such as asthma and allergy problems.
5 Simple HVAC Maintenance Steps
- Use high quality furnace filters. Air filters for your Heating and Cooling system all have a MERV rating. These ratings range from 1 (least efficient) to 16 (extremely efficient). Using a higher MERV rating will deliver cleaner air but this needs to be balanced with the higher costs of more efficient filters. Typically MERV 7-12 range gives the best balance of cost vs air quality.
- Change Air Filters Regularly. Typically filters should be changed monthly. Some higher MERV rated filters will need to be changed every 3 months. Dirty filters will restrict the airflow and allows dust to build up in your ducting and throughout your system.
- Dust registers and return vents. While many people will dust their homes weekly, most will forget to dust those registers and air return vents. Use a damp cloth and wipe down the registers and vent grills to help control dust being introduced into your system.
- Check for mold. Any place moisture builds up is a place mold can grow. Check ducts, condensate drip pan and drain, evaporator coils, and the air handler for signs of moisture and mold growth. If you find signs of mold, call a professional to help with treatment.
- Keep the air moving: Run your system with the fan always on. Without enough air circulation, allergens will tend to accumulate at a higher rate. Use your system to filter and provide a constant source of fresh air.
By doing regular HVAC maintenance, you can ensure that your system runs reliably and helps clean your indoor air. Schedule a spring HVAC maintenance appointment with your HVAC company to have your system maintained and tuned up.
