How long will air ducts remain clean?
Once you've done with air duct cleaning, you need to make sure the ducts are not damaged. If there are cracks and the duct parts are not connected properly, the ducts will get dirty pretty soon. You need to make sure the joints and holes are sealed well to keep the ducts clean for 5-6 years.
Are my allergies a result of dirty ducts?
If your allergies are intensified as soon as you walk home and you didn't have similar symptoms in the past, most probably you must blame the filthy air ducts. The mold, fungi and particles accumulated in the ducts are transferred with air and make you sick. Our experts in Lakewood suggest immediate air duct cleaning.
Which parts of the HVAC must be cleaned?
All parts of the unit must be kept very clean. Condenser unit cleaning is important and must take priority because it is placed outside and concentrates more dirt than other parts. Of course, air filter cleaning is equally significant because it will restrain some dirt transferred with air. Keep the evaporator clean, too.
