Frequently Asked Questions
What SEER rating should I choose for my new AC?
Minimum efficiency is 14 SEER. High-efficiency systems range from 16-21+ SEER. Higher SEER means lower operating costs — we'll help you calculate the payback period.
Do I need to replace my ductwork when installing a new AC?
Not always. We'll inspect your existing ductwork and let you know if any modifications are needed for optimal performance with your new system.
How long does AC installation take?
A standard central AC installation typically takes 4-8 hours. We'll give you a specific timeline during your consultation.
Can I install AC if I only have a furnace?
Yes! We can add central air conditioning to homes with existing forced-air furnaces. We'll evaluate your ductwork and recommend the best approach.
