How often should I have my AC serviced?

We recommend annual AC maintenance in spring before the cooling season. This ensures optimal performance, prevents breakdowns, and can reduce energy costs by up to 15%.

What size AC unit do I need for my home?

AC sizing depends on square footage, insulation, windows, and more. Our technicians perform a Manual J load calculation to determine the perfect size for your home. Oversized or undersized units waste energy.

How long do air conditioners typically last?

With proper maintenance, central AC units last 15-20 years. If your system is 10+ years old and needs frequent repairs, it may be more cost-effective to replace it with a high-efficiency model.

What's the difference between SEER and SEER2 ratings?

SEER2 is the new efficiency standard as of 2023. Higher SEER2 ratings mean greater efficiency and lower operating costs. We can help you choose the right efficiency level for your budget and climate.
