4. Seasonal Timing: 5-15% Off
HVAC contractors are significantly less busy in spring and fall. This directly translates to lower prices and faster scheduling.
Spring (March-May)
5-15% off
Best availability. Contractors want to fill their spring calendar and are most negotiable.
Fall (Sept-Nov)
5-15% off
Post-summer slowdown. Same discount potential as spring.
Winter (Dec-Feb)
10-20% off
Hardest time to work (cold, snow) but maximum contractor availability.
Dollar impact: On a $7,000 installation, a 10% off-season discount saves $700. On a $12,000 new installation, it saves $1,200.
5. Getting 3 Competitive Quotes
Price variation between contractors for the same job can be 20-40%. Getting 3 quotes is the single highest-impact action you can take.
What to specify in each quote
- ✓Exact equipment model and SEER2
- ✓Same tonnage for all quotes
- ✓Include or exclude permit
- ✓Labour warranty duration
- ✓What happens if new ductwork is needed
How to compare quotes fairly
- ✓Total installed cost (not just equipment)
- ✓Warranty terms (parts and labour)
- ✓Timeline and scheduling
- ✓Contractor license and insurance
- ✓Reviews: Google, BBB, Yelp
Using quotes to negotiate
- ✓Share lower quote with preferred contractor
- ✓Ask if they can match or beat the price
- ✓Negotiate on extras (smart thermostat, UV filter)
- ✓Ask about 0% financing options
- ✓Never pay more than 50% upfront
6. Upsells to Skip (and What Actually Matters)
| Upsell | Typical Added Cost | Verdict |
|---|---|---|
| UV air purifier / germicidal light | $300-$800 | Skip it. Limited evidence of benefit in typical homes. |
| Extended warranty (contractor-sold) | $500-$1,500 | Skip it. Manufacturer warranty (10 yr) is usually sufficient. |
| Premium 1-inch filters at markup | $50-$150/year | Buy your own from Amazon/Home Depot at 1/3 the price. |
| Smart thermostat at contractor markup | $200-$400 | Buy a Nest or Ecobee yourself for $130-$200 and ask them to install it. |
| Duct cleaning on day of install | $300-$600 | Rarely necessary unless system has been unused for years. |
| Annual maintenance plan (new system) | $150-$300/yr | Low value on brand new system under warranty. Consider in year 4-5. |
| Demand control ventilation add-on | $500-$1,500 | Useful in commercial settings. Rarely needed in homes. |
