The average central AC installation takes one full day, depending on the size of your home and the complexity of the job. If ductwork modifications or additional zoning are required, it may take slightly longer. Our team ensures minimal disruption and same-day cooling whenever possible.
The correct size depends on your home's square footage, insulation, window placement, duct layout, and other factors. We perform professional load calculations to ensure your system is properly sized—too small and it won't cool effectively; too large and it will short-cycle and waste energy.
SEER stands for Seasonal Energy Efficiency Ratio. It measures how efficiently your air conditioner converts electricity into cooling. The higher the SEER rating, the more efficient your system will be. In Illinois, we typically recommend systems with SEER ratings between 14 and 20+, depending on budget and efficiency goals.
If your system is over 10-15 years old, experiences frequent breakdowns, or struggles to cool your home effectively, it's likely more cost-effective to replace it. A new system will offer better comfort, lower energy bills, and warranty protection.
