### How to Write a HVAC Estimate in 5 Steps

1. **Step 1: Perform a Load Calculation**  
   Run a Manual J load calculation before sizing equipment. Measure the home’s square footage, check insulation levels, count windows, and note climate zone. Oversizing wastes money, undersizing means callbacks. Get this right first.

2. **Step 2: Spec the Equipment**  
   List exact equipment models with specifications. Include SEER2 ratings, BTU capacity, warranty terms, and ENERGY STAR status. For a full system: condenser, air handler or furnace, coil, thermostat, and line set. Use distributor pricing for your cost basis.

3. **Step 3: Calculate Labor and Ductwork**  
   A standard residential HVAC install takes a 2-person crew 2-3 days. Factor in ductwork modifications, electrical upgrades, and refrigerant charging. Complex jobs (attic units, multi-zone) add 1-2 days. Price labor at $65-$95/hr depending on your market.

4. **Step 4: Add Permits and Markup**  
   HVAC work requires permits in most jurisdictions ($150-$500). Add your markup (20-30% is standard). On a $12,000 system, 25% markup is $3,000. Include warranty terms. Most manufacturers require licensed installation for coverage.

5. **Step 5: Send It and Follow Up**  
   Export a clean PDF with equipment spec sheets attached. Send within 24 hours of the site visit. HVAC is seasonal. In summer, homeowners are comparing 3-4 bids. Speed and professionalism win the job.

### Average HVAC Job Costs to Guide Your Estimates

Use these benchmarks as starting points. Actual costs vary by region, materials, and job complexity.

| Furnace replacement                                | $1,500 – $3,500        | $1,500 – $2,500      | $4,000 – $7,500      |
| Ductwork replacement (whole home)                 | $2,000 – $4,000        | $3,000 – $5,000      | $6,000 – $12,000     |
| Mini-split install (single zone)                  | $1,500 – $3,000        | $1,000 – $2,000      | $3,500 – $6,000      |
| AC repair (compressor/coil)                       | $400 – $1,500          | $300 – $800          | $800 – $2,500        |

### Estimating Best Practices for HVAC Contractors

1. **Always run a Manual J calculation**  
   Never eyeball equipment sizing. An oversized system short-cycles, wastes energy, and creates humidity problems. A Manual J calc takes 30 minutes and proves you’re the professional in the room.

2. **Offer Good-Better-Best equipment tiers**  
   14 SEER2 (budget), 16 SEER2 (mid), 20+ SEER2 (premium). Clients close faster with options, and your average ticket goes up 25-40%. Show the energy savings math for each tier.

3. **Include maintenance plan upsell**  
   Bundle a 1-year maintenance agreement ($200-$400/yr) into your estimate. It creates recurring revenue and keeps you top-of-mind for the next system. Most clients say yes at point of sale.

4. **Spec exact model numbers**  
   Generic ‘AC unit’ estimates lose to specific ‘Carrier 24ACC636A003’ estimates. Clients research model numbers and see you’ve done the engineering. It also prevents scope disputes.

5. **Factor in rebates and incentives**  
   Federal tax credits (up to $2,000 for heat pumps), utility rebates, and manufacturer promos lower the client’s out-of-pocket. Show the net cost after incentives. It closes deals.

6. **Document existing system condition**  
   Photograph the old equipment, ductwork, and electrical panel. Note model numbers and age. This justifies replacement, sets expectations, and protects you if something goes wrong post-install.
