Your evaporative coil is one of the major components in your air conditioning system.

It sits in a box called a plenum just above your furnace. If your evaporative coil is dirty, having the coil professionally cleaned by an experienced HVAC technician is one of the best things you can do for the health and efficiency of your air conditioner, and will help prevent expensive furnace blower repairs as well.

When your evaporative coil gets dirty, it disrupts the smooth flow of air air through your HVAC system, and places tremendous stress on the blower motor inside your furnace.

The additional stress a dirty evap coil places on the blower motor will eventually cause the motor to fail. Having a trustworthy company replace the blower motor in your furnace is not cheap. All of the well-known, reputable heating and air companies in Denver charge anywhere from $1,000 to as much as $1,700 to replace a blower motor.

Depending on how dirty your evaporative coil is, it may need to be removed from the plenum and cleaned by hand. Only experienced and qualified HVAC technicians should be allowed to perform this service on your coil. The average duct cleaning technician isn’t EPA certified to handle and recover the refrigerants, and can cause serious damage to your air conditioning system.

Neglecting to have a dirty evaporative coil cleaned results in higher utility bills, and will eventually lead to expensive furnace repairs.

If ignored long enough, a dirty coil can even result in having to replace your furnace and/or your air conditioner several years before you would otherwise. If you’re already planning to have your air ducts cleaned, you can avoid expensive repairs or early system replacement simply by having a qualified HVAC technician clean your evaporative coil at the same time.

As part of your duct cleaning service, our technicians will thoroughly inspect the evaporative coil. If it’s dirty, they will let you know. However, unlike many of the duct cleaning companies here in Denver who engage in bait & switch pricing schemes, our technicians will only recommend cleaning the evaporative coil if it actually needs to be cleaned.
