ER Air is your trusted source for professional HVAC and air duct cleaning services throughout the greater Chicago area. With over 15 years of industry experience, our team of talented and highly trained technicians will clean and maintain the ventilation systems throughout your entire home, saving you time, money, and the stress of trying to do it on your own. Dryer vent cleaning is recommended every 12 to 15 months depending on the length and configuration of the dryer exhaust pipe. Over time, lint and debris accumulate in the dryer vent, creating clogs and airflow restrictions that can lead to a number of dryer vent problems. This includes longer drying cycles which is costing you more money, time, and wear and tear on your dryer unit which could lead to costly appliance repairs or potential fire hazards. Birds nests are also commonly found on the exterior vents and proper vent cover installation by ER Air will prevent this from happening. Through regular dryer vent cleaning, our licensed ER Air technicians can inspect and assure you that your dryer vent is always up to code, operating safely and running as efficiently as possible. From installing dryer vent ducts to performing inspections and repairs, ER Air has you covered! NADCA's rule of thumb for consumers is that "if your ducts look dirty, they probably are" and that dirty air systems should be inspected and cleaned by a reputable, certified HVAC professional today. Although it may seem minor at the time, allowing dirt and debris to accumulate in your air ducts can cause major problems down the line. Over time, all that dust and dirt will block airflow and keep your ventilation systems from working efficiently or correctly. This means higher energy bills, possible repair costs to your unit and even full replacement projects.
