Option B — Mid-Tier
• 2.5-ton two-stage heat pump
• 15.2 SEER2
• Wi-Fi thermostat
• $11,200

Option C — Premium
• 2.5-ton inverter heat pump
• 18 SEER2
• Smart thermostat with remote sensors
• $14,000

All options listed as:
• Reuse existing ducts
• New pad + disconnect
• Old equipment removal included
• 10-year parts warranty
• 1-year labor warranty

The Big Picture

This quote offers three equipment tiers: a basic single-stage, a quieter two-stage, and a high-efficiency inverter. The ductwork is reused across all options, and the installation scope appears consistent. The price differences mainly come from equipment quality and thermostat features.

What Each Option Really Means

A — Basic (Single-Stage)

This is the simplest and loudest option. It turns fully on or fully off. Good for mild climates or tight budgets, but not the most comfortable or efficient.

B — Mid-Tier (Two-Stage)

Better comfort and quieter operation. Runs on a lower stage most of the time, which improves temperature stability and reduces noise. A common "best value" choice.

C — Premium (Inverter)

Most comfortable and quiet. Adjusts its output smoothly based on the home's needs. Best efficiency, best cold-weather performance, and usually the longest life expectancy.

What's Missing or Unclear

• No model numbers: Important for comparing performance and noise levels.
• No static pressure data: Ducts may or may not support inverter airflow.
• No electrical details: Breaker sizes differ between stages.
• No load calculation: All options are 2.5 tons — but no proof that's the right size.

Comfort & Efficiency Notes

The comfort gap between single-stage and inverter is noticeable. Two-stage sits in the middle and is often a good balance of price and performance. Cold-climate areas benefit most from inverter systems.

Price Insight

Prices range from $9,800 to $14,000, which is typical for basic → premium equipment tiers. The value depends heavily on your climate and comfort preferences.

Red Flags to Consider

• All options reuse ducts without airflow testing.
• No load calculation to justify the 2.5-ton size.
• No electrical details or breaker requirements.
• Basic option may be noticeably loud.

Questions You Can Ask

• "Can you provide the model numbers for all three options?"
• "Which option is best for noise, comfort, and long-term performance?"
• "Were my ducts tested to confirm they support a two-stage or inverter system?"
• "What electrical upgrades are needed for each option?"
• "Can you share a load calculation to confirm the 2.5-ton size?"
