JT's Air Duct Cleaning Saint JohnS University, MN

Evaporator Coil Cleaning

The evaporator coil is where the cooling happens. It is wet and tightly spaced, making it a magnet for dust. When dust builds up, it acts as an insulator, preventing the coil from absorbing heat. This leads to ac not cooling and can cause the coil to freeze over. We provide ac coil cleaning service, using specialized foam cleaners and combs to gently remove the debris without damaging the delicate aluminum fins.

Blower Wheel Cleaning

The blower wheel pushes the air through your home. If the blades are coated in dust, the fan becomes heavy and unbalanced. This strains the motor, reduces airflow, and can lead to noisy operation or motor burnout. Our dirty hvac blower cleaning service removes this weight, allowing the fan to spin freely and move more air with less energy.

The Efficiency Upgrade

A clean system is an efficient system. By combining evaporator coil cleaning and duct service, you are essentially giving your HVAC system a tune-up. This lowers the amperage draw of the motor and compressor, directly resulting in lower monthly utility bills and a longer lifespan for your expensive equipment.

Frequently Asked Questions

• How do I know if my coils are dirty? If your AC runs constantly but the house doesn't get cool, or if you see ice forming on the lines, dirty coils are a likely culprit.
• Do you take the unit apart? Yes. To clean the blower wheel and evaporator coil properly, we often need to open the plenum and access the internal components.
• Can I clean the coils myself? It is risky. The fins are razor-sharp and bend easily. Using the wrong chemical or too much pressure can destroy the coil, costing thousands to replace.
• Does this prevent breakdowns? Yes. The #1 cause of HVAC failure is dirt. Keeping the components clean prevents overheating and mechanical stress.
• How often should coils be cleaned? Ideally, every 1-2 years, depending on your filter maintenance. If you use cheap fiberglass filters, the coils get dirty much faster.
