Caring for Your Unico High-Velocity System in Chicago
If your Chicago home relies on a Unico high-velocity air conditioning system, you already know it isn’t quite like a conventional central air setup. Those compact supply outlets, the flexible mini-ducts threaded through walls and ceilings, and the high-velocity airflow that quietly removes humidity all require a maintenance approach tailored to the technology. When neglected, even a well-engineered Unico system can lose efficiency, develop pressure imbalances, or struggle to keep older homes evenly cooled. That’s where regular professional attention pays off.
At All Temp Heating & Air Conditioning, we have spent years servicing the unique needs of Chicago homeowners, including those with specialized comfort systems like Unico. As a family owned and operated company, we understand that your air conditioning isn’t just equipment – it’s the difference between a comfortable summer and a miserable one. Our courteous, fast, and friendly staff is here to service all of your needs, whether that means a routine tune-up or a deeper diagnostic.
What Makes Unico Maintenance Different
Unico systems use small-diameter ducting and an aspirating air handler that delivers air at higher velocity than traditional systems. This design is ideal for older Chicago homes, historic buildings, and properties where running large rigid ductwork simply isn’t practical. The trade-off is that the system depends heavily on proper airflow, sealed connections, and a clean coil to perform as intended. A small reduction in airflow can have an outsized effect on cooling capacity and humidity control.
Because of this, our maintenance methodology focuses on the components that matter most to high-velocity performance. We inspect the modular air handler, verify that the sound-attenuating tubing remains properly seated, and check the supply outlets throughout the home for blockages or air leaks. We also examine the system’s static pressure, since high-velocity equipment operates within tighter pressure tolerances than standard split systems. Catching a developing pressure issue early protects both comfort and the longevity of the blower motor.
Our Unico Maintenance Process
When our technicians arrive for a Unico maintenance visit, we follow a thorough, repeatable process designed to leave nothing to chance. We treat every system as if it were in our own home, paying close attention to the details that keep these specialized units running smoothly through Chicago’s demanding cooling season.
- Coil inspection and cleaning: We clean the evaporator and condenser coils so heat transfer stays efficient and the system doesn’t overwork itself during peak summer heat.
- Airflow and static pressure testing: We measure airflow at the outlets and confirm static pressure falls within Unico’s recommended range to maintain proper dehumidification.
- Refrigerant level verification: We check refrigerant charge and look for any signs of leaks that could reduce cooling capacity over time.
- Condensate drain service: We clear the drain line and pan to prevent water backups that can damage walls, ceilings, or the air handler itself.
- Electrical and component check: We tighten connections, test the blower motor, and inspect controls so small electrical faults don’t grow into costly failures.
Common Scenarios We Address
Many of our calls come from homeowners in historic neighborhoods who installed Unico precisely because it preserved the architecture of their property. Over time, dust accumulation and slightly loosened tubing connections reduce airflow to upper floors, leaving bedrooms warmer than the rest of the house. Our maintenance restores balanced cooling so every room feels consistent.
Other clients reach out when humidity creeps up despite the system running constantly. High-velocity systems excel at removing moisture, but only when airflow and refrigerant charge are correct. We diagnose the root cause rather than simply recommending more runtime. We also serve property owners who recently purchased a home with an existing Unico system and want a baseline assessment before the cooling season begins. That proactive inspection often uncovers deferred maintenance that the previous owner overlooked.
