Keep your systems running  and your warranty valid.

Residential: Home systems should be professionally serviced once a year, ideally in spring before the intense summer heat hits, to clear out dust, check gas levels, and prevent unexpected breakdowns.

Commercial: Business systems require more frequent maintenance due to heavy daily use and strict workplace health guidelines. Depending on the environment, commercial systems need servicing quarterly (every 3 months) or bi-annually (every 6 months).

The most common culprits are heavily clogged dust filters restricting airflow, an incorrect thermostat setting, or a refrigerant gas leak that requires a licensed technician to locate and repair. Commercial: In a commercial setting, this often points to a tripped circuit breaker, a faulty compressor, or an issue with the central building management system (BMS) overriding the local controls.

Residential: This is usually caused by a blocked condensate drain due to algae, dust, or mold buildup. While it isn't dangerous, you should turn the unit off immediately to prevent water damage to your walls and ceilings.

‍Commercial: Indoor leaks in a business often point to a blocked drain line or a failing condensate pump. It needs prompt attention to prevent safety hazards like slippery floors or damage to electronic office equipment.

Residential: This is commonly known as "dirty sock syndrome" and is caused by bacteria, mold, or mildew growing on the dark, damp internal evaporator coils or inside a clogged drip pan. It needs a deep professional chemical clean to flush out the microbial growth safely and restore fresh, healthy airflow.

‍Commercial: In an office or commercial building, a musty odor usually indicates that moisture has built up inside the main ductwork or that stagnant water is sitting in a blocked condensation drainage line. It requires immediate attention to protect indoor air quality and ensure compliant workplace health standards.
