How to Compare HVAC Quotes (Apples to Apples)
You've requested quotes from three contractors. One quote is $12,000, another is $18,000, and the third is $24,000. Which one is the best deal?
The answer: You can't tell yet. Until you understand what's actually included in each quote, you're not comparing apples to apples.
Common Line Items in HVAC Quotes
1. Equipment
- Brand and model number - Is it Carrier Infinity, Lennox, or a budget brand?
- Efficiency rating - 95% AFUE furnace vs 80%? SEER² 16 vs 20+?
- Features - Single-stage, two-stage, or variable-speed?
- Warranty coverage - 5 years vs 10 years parts warranty?
2. Labor & Installation
- Removal and disposal of old equipment
- Installation labor hours (can vary 2-4x based on complexity)
- Startup and testing
- Commissioning and calibration
3. Materials & Add-Ons
- Refrigerant lines - Are they being replaced or reused?
- Thermostat - Basic programmable vs smart WiFi?
- Condensate drain pump if needed
- Air filter - Standard vs MERV 11/13?
- Ductwork modifications or repairs
- Electrical upgrades - Circuit breaker, disconnect, wiring
4. Permits & Fees
- Building permits (required in most Bay Area cities)
- Inspection fees
- HOA approval if applicable
5. Extras That Matter
- Extended warranties
- Maintenance plan for first year

Red Flags to Watch For
🚩 "Bid is good for equipment only, installation extra" 🚩 No specific model numbers listed 🚩 "We'll reuse your existing lines" (when they're 15+ years old) 🚩 No mention of permits or inspections 🚩 Pressure to sign immediately with "today only" pricing 🚩 Significantly lower than other quotes with no clear reason
Questions to Ask Every Contractor
- What exact model are you installing? (Get the full model number)
- What's included in installation? (Itemize everything)
- Who handles the permits? (You or them?)
- Do you provide rebate assistance? (This can save thousands)
- What's your warranty coverage? (Parts, labor, workmanship)
- When can you start? (Realistic timeline)
- What's your payment schedule? (Never pay 100% upfront)
Making Your Decision
The "best" quote isn't always the cheapest. Consider:
- Total cost of ownership over 15-20 years (efficiency matters!)
- Comfort features (variable-speed = better comfort)
- Warranty protection (longer = better)
- Contractor reputation (check reviews, licenses, certifications)
- Rebate maximization (can offset $2,000-5,000)
