Questions & Answers
Frequently Asked Questions
Should I repair or replace my air conditioner?
It depends on the age of your system, how often it breaks down, and how much the repair would cost compared to its value. If your AC is older, needs frequent repairs, or your energy bills keep climbing, replacement often makes more sense. Our technicians will give you an honest recommendation either way.
How do I know what size AC my Charleston home needs?
Proper sizing depends on your square footage, insulation, windows, sun exposure, and ductwork. An oversized unit can short cycle and leave your home feeling damp, while an undersized one runs constantly. We do an in-home assessment to find the right fit.
Do you offer free estimates on AC replacement?
Yes. We offer free estimates on new systems and replacements. We will visit your home, review your options, and give you clear pricing before any work begins.
How long does a new AC installation take?
Most straightforward replacements are completed in about a day. Projects that need ductwork changes or a different system type can take longer. We will give you a clear timeline during your estimate.
