HVAC Drain Pan Maintenance

Midwest Duct Cleaning specializes in HVAC drain pan restoration on all sizes of units. Here are a few signs to look for that will help determine if your drain pan may require maintenance:

Water Stains Around Your Unit

Water stains around your HVAC unit may indicate that your drain pan needs cleaning or maintenance. A clogged or dirty drain pan can cause water to back up and escape from the unit. This is not only a sign of a potential problem but is also unsightly and can damage your flooring or wall coverings.


When checking for water stains, look for puddles on the ground, discoloration on walls or ceilings, and any visible staining on the unit itself. If you spot any water stains, it is essential to take action immediately to prevent further damage.


The first step is to identify the source of the water. Next, contact a professional HVAC technician to investigate the issue if you cannot do this. If the technician determines the cause of the water leakage is a dirty or clogged drain pan, it should be cleaned or replaced as soon as possible.


It is essential to keep your HVAC drain pan clean and clear of debris to prevent water leakage and potential damage. Keep an eye out for water stains, and contact a professional if you need help with your drain pan maintenance.

Unexplained High Water Bills

If your drain pan is blocked and not draining correctly, the system will work harder and longer to remove the condensation from your home. This can lead to more frequent cycles of your HVAC, resulting in an increased demand for water and an increased water bill. In addition, a clogged drain pan can cause your system to run longer and harder, resulting in a higher-than-normal energy bill.


It's essential to check the drain pan regularly to ensure that it isn't clogged with dirt and debris, which can prevent water from draining correctly. Suppose you notice a sudden increase in your water bill. In that case, it's best to contact a professional HVAC technician right away to inspect the condition of your drain pan and provide any necessary cleaning or maintenance services. Midwest Duct Cleaning Services offers comprehensive drain pan maintenance services to help keep your system running smoothly and efficiently.

Musty Smells Coming from Your Vents

Keeping your drain pan in good condition is essential for maintaining healthy indoor air quality. If you start to notice a strong, musty smell, this can indicate that your drain pan is not draining correctly and has become clogged with debris and contaminants. When the drain pan overflows and spills water onto the floor of your home, mold and mildew can begin to form, causing a musty smell. 


If you notice a musty odor, it is essential to contact a professional HVAC technician immediately. The technician will inspect and determine whether your drain pan requires cleaning or you need an HVAC drain pan replacement. In addition, the technician will check for any other causes of the musty smell, such as blocked ductwork or a dirty air filter. Once the source of the scent has been identified, they will take the necessary steps to restore your air quality and ensure your family is breathing clean air.
