Common questions
Quick answers, before you call.
Still have a question? Reach our dispatch line 24/7 — a real person picks up.
Do you focus on a single brand or any AC system?
Our crew has experience installing and servicing cooling systems of almost every age, style, and brand.
Is there any way to make a new AC unit more affordable?
We accept a range of payment methods and offer flexible financing options for client convenience.
Are any guarantees or warranties available?
Most products we install come with a manufacturer's warranty in addition to our team's total satisfaction guarantee.
How long does install take?
Most full system replacements complete in 1–2 days. New installs in homes without existing ducting take longer; we'll provide a detailed timeline up front.
How do I know what size system I need?
We perform a load calculation rather than guessing from square footage — sizing it correctly is the single biggest factor in long-term comfort and bills.
