Factors That Influence Cost

Unit Size (Tonnage):
1 ton = 12,000 BTUs/hour (cooling capacity).
Rule of thumb: 1 ton for every 500–600 sq. ft. of living space.
SEER Rating:
Higher SEER (Seasonal Energy Efficiency Ratio) = More energy-efficient, higher upfront cost.
Standard: 13–16 SEER; Premium: 20+ SEER.
Labor & Installation:
Ductwork modifications, electrical wiring, concrete pad, and framing increase costs.
Brand:
Budget Brands: Payne, Coleman, Comfortmaker (<$2,000).
Premium Brands: American Standard, Carrier, Lennox (>$3,000).
Additional Features:
Smart thermostats, noise-reduction fences, or zoning systems add to the cost.

DIY vs. Professional Installation

DIY:
Not recommended due to complexity (EPA certification required for refrigerant handling).
Risk of improper installation can lead to higher repair costs.
Professional:
Ensures proper sizing, safe installation, and compliance with local codes.
Costs include labor ($50–$150/hour) and permits ($50–$200).

FAQs
