Should You Repair or Replace?

The industry-standard "$5,000 Rule" multiplies your system's age by the repair cost. If the result exceeds $5,000, replacement is usually the smarter investment.

Calculator FAQs

How accurate are these calculators?

These tools use standard industry formulas to give you a solid ballpark estimate. For precise sizing and cost analysis, schedule a free in-home assessment with our technicians. Every home is different, and factors like ductwork condition, window quality, and attic insulation can shift the numbers.

What is the $5,000 Rule?

The $5,000 Rule is a widely used HVAC industry guideline. Multiply your system's age in years by the estimated repair cost. If the result exceeds $5,000, it's generally more cost-effective to replace the system rather than keep sinking money into repairs.

What SEER rating should I choose for Louisiana?

In Louisiana's hot, humid climate, we recommend at least SEER 16 for good efficiency. SEER 18-20+ units offer the best long-term savings, especially with our cooling season running from April through October. Higher SEER systems also tend to dehumidify better.

How do I know what size AC I need?

System sizing depends on your home's square footage, insulation quality, ceiling height, sun exposure, and more. Our sizing calculator gives a quick estimate, but an in-home evaluation provides the most accurate sizing. An oversized or undersized system wastes energy and reduces comfort.

Do you offer financing for new systems?

Yes. We offer 12 months at 0% interest and 60 months at 7.99% APR through WiseTack (apply online) or Service Finance (call us and we'll walk you through it). Use our system cost estimator above to get a ballpark.
