Learn moreHow much does AC installation cost?
Cost depends on the size of your home, the efficiency tier you choose, and whether ductwork needs any modification. We provide a clear, itemized quote before any work begins — ask us about financing options for larger installations.
How long does AC installation take?
A straightforward like-for-like replacement is often completed in a single day. Installations that involve ductwork changes or a ductless mini split system can take longer, which we'll outline upfront.
What SEER rating should I choose?
Higher SEER ratings cost more upfront but lower your cooling bills over time. The right choice depends on how long you plan to stay in the home and your budget — we'll walk you through the actual payback math rather than just pushing the highest number.
Do you install ductless mini splits?
Yes — ductless mini splits are a good option for additions, garages, or homes without existing ductwork. We can walk you through whether a mini split or a central system makes more sense for your situation.
