Buying HVAC equipment online and hiring your own installer can save you thousands compared to a traditional contractor quote. Here's a step-by-step guide to doing it right.
Step 1: Determine What You Need
Before shopping, figure out your current system's specifications:
Buy the same name-brand HVAC system the pros install — shipped factory-direct to your door. No middleman, free delivery, 5-star rated, and financing available.
- System type: Split system (condenser + air handler/furnace) or package unit?
- Size: What tonnage is your current system? Check the model number on your existing equipment.
- Fuel type: Gas furnace, electric heat pump, or straight cool with heat strips?
- Refrigerant: As of 2026, new installations require R-32 or R-454B. R-410A systems can only be used as replacement components.
Step 2: Choose Your Equipment
Shop at a factory-direct retailer like Furnace Direct. Key things to compare:
- SEER2 rating: Higher = more efficient. 14.3 SEER2 is the minimum; 17–18 SEER2 for premium systems.
- Brand: Goodman (Daikin), Whirlpool HVAC (Rheem), Day & Night (Carrier/ICP) are all tier-1 manufacturers.
- Warranty: Look for 10-year parts warranty with registration. Day & Night includes a No Hassle Replacement warranty on premium models.
Step 3: Find an Installer
You have three options:
- Ask Furnace Direct: We coordinate installation with licensed contractors in many areas. Call (888) 762-1334.
- Hire locally: Search for "HVAC installer near me" and get quotes for labor-only installation. Expect $1,500–$3,000 for a standard residential swap.
- DIY: Legal in some states for homeowners, but check your local requirements. Electrical and refrigerant connections require proper certifications.
Step 4: Order and Schedule
Once you've selected your equipment and lined up an installer, place your order. Furnace Direct ships nationwide — same-day delivery is available in select areas. Coordinate your delivery date with your installer so the equipment arrives the morning of installation.
How Much Can You Save?
A typical 3-ton AC replacement quoted by a contractor at $9,000–$12,000 can be done for $5,500–$7,500 by buying equipment factory-direct and hiring a separate installer. That's a savings of $3,000–$5,000 on the same brand-name equipment with the same manufacturer warranty.
