2. Efficiency Ratings

Higher SEER, AFUE, or HSPF ratings increase upfront costs by $350–$1,500, but save on energy bills long-term.

3. Climate and Location

Cold regions may require larger heating capacities.
Humid areas may need additional dehumidifying capabilities.

4. Installation Complexity

Roof-Mounted Units: Add $1,000.
Space Construction (for indoor units): $1,000–$2,500.

DIY vs. Hiring a Pro

DIY: Only practical for window AC units ($60–$300 savings).
Professional Installation: Costs $1,500+ but ensures safety and energy efficiency.

Money-Saving Tips

Go Energy-Efficient: Look for tax credits or rebates on ENERGY STAR® models.
Replace Off-Season: Book in spring or fall for better rates.
Consider Mini-Splits: Cheaper for zone-specific cooling/heating.
Upgrade During New Builds: Combine installation with other projects for discounts.
Ask About Financing: Many HVAC contractors offer payment plans.

A well-installed HVAC system not only keeps your home comfortable but also boosts energy efficiency and long-term savings.
