Who This Checklist Is For
If you’re a small HVAC contractor, a one-truck operation, or just starting your own service business, you’ve probably run into the same wall I have. You need reliable equipment—a Daikin AC condenser, a 7.5-ton package unit, maybe a Milwaukee blower or an Ego snow blower for the shop—but vendors often match you with the big guys. The quote feels off, or the fine print hides costs that blow your budget.
This checklist is for those exact moments. It’s based on over 6 years of tracking every invoice, comparing 40+ vendors, and learning the hard way where the hidden money goes. It has 6 steps. Follow them in order, and you’ll see the total cost of ownership (TCO) before you sign anything.
Step 1: Define the Specifics (Don’t Assume “Standard”)
The Trap: Asking for a “Daikin 7.5 ton package unit” and getting three wildly different prices.
The Fix: Write down the model number. Not the series—the specific model. I learned this when I requested a quote for a “7.5 ton package unit” and one vendor quoted a gas/electric unit, another quoted a heat pump, and a third quoted a cooling-only model. The price difference was $1,200. That’s not a market variation; that’s a specification mismatch.
Checklist point: Confirm: BTU output, refrigerant type (R32), voltage (208-230V vs. 460V), and included controls (thermostat or not). If it’s a blower (like a Milwaukee blower), confirm CFM and duct connection size. If it’s a snow blower (like an Ego), confirm the stage (single vs. two-stage) and battery platform.
Everything I’d read said “just get the spec sheet.” In practice, the spec sheet didn’t match what the vendor actually shipped. Twice.
Step 2: Get 3 Quotes, But Structure Them Identically
The Trap: Comparing a quote that includes delivery, warranty registration, and disposal of the old unit against one that doesn’t.
The Fix: Send the same line-item template to every vendor. I use a spreadsheet with these columns: line item, unit price, quantity, delivery fee, warranty fee, disposal fee, and total. No “free delivery” without verifying it’s not built into the unit price.
When I compared our Q1 and Q2 results side by side—same vendor, different specifications—I finally understood why the details matter so much. Vendor A quoted $4,200 for a Daikin condenser. Vendor B quoted $3,800. I almost went with B until I calculated TCO: B charged $200 for delivery, $150 for a “warranty registration fee,” and $75 for disposal. Total: $4,225. Vendor A’s $4,200 included everything. That’s a 10% difference hidden in fine print.
Step 3: Separate Product Cost from Install/Setup Cost
The Trap: Combining equipment and labor into one lump price. It’s common for vendors to quote “installed” prices for package units or heat pumps, especially for toB customers. But that hides the ratio.
The Fix: Ask for an itemized breakdown. I’ve seen quotes where the “installation” line was 60% of the total. For a 7.5 ton package unit, that’s borderline dishonest. Split it: equipment cost, line set, electrical, pad, labor, permit, and disposal. If they refuse to itemize, that’s a red flag.
In Q2 2024, when we switched vendors for a 7.5 ton Daikin package unit, the new vendor’s “lower” total quote turned out to have a $400 higher equipment cost—but the installation was $600 lower because they didn’t sub it out. If I’d only looked at the total, I’d have missed the structural difference.
Step 4: Check for “Small Order” Penalties (The Hidden Tax)
The Trap: Being a small contractor and getting hit with surcharges for ordering less than truckload.
Trigger: When I was starting out, the vendors who treated my $200 orders seriously are the ones I still use for $20,000 orders. Small doesn't mean unimportant—it means potential. But some vendors see “small” as an excuse to add fees.
The Fix: Ask explicitly: “Is there a minimum order amount? A small order surcharge? A pick-and-pack fee?” In my experience, 3 out of 10 vendors have a hidden small order fee of $25–$75. For a single Daikin condenser or a Milwaukee blower, that’s often 5–10% of the product cost.
One supplier charged a “restocking fee” of 20% for any order under $500. I didn’t see it because it was buried in their terms and conditions. The first time I ordered a single thermostat ($120), I got hit with a $24 fee. That’s $24 I didn’t budget for.
Step 5: Calculate the True Cost of “Free Shipping”
The Trap: Assuming “free shipping” means no shipping cost.
The Fix: Ask where the item ships from and what the delivery window is. “Free shipping” often means ground shipping from a distribution center 1,500 miles away. For a 7.5 ton package unit weighing 300+ lbs, ground shipping can take 5–7 business days—if it arrives undamaged. Freight damage is common, and the “return” process often involves a restocking fee and a 2-week delay.
I had an Ego snow blower delivered “free” in Q3 2024. It arrived with a cracked housing. The vendor said I had to file a claim with the carrier. That took 3 weeks and a ton of phone calls. My “free” shipping ended up costing me about $100 in admin time and lost productivity. Next time, I pay the $35 for liftgate delivery and insurance.
Step 6: Factor in the “Can Am Air Filter” Test
The Trap: Ignoring consumables and accessories when comparing total costs.
The Fix: If you’re buying a Daikin AC condenser, do you also need a filter? A thermostat? A pad? If you’re ordering a snow blower, do you need spare shear pins or oil? Vendors know you need these, and they price them accordingly. My rule: before I compare final quotes, I add up the cost of all necessary accessories from the same vendor plus the lead time.
At a trade show, I saw a “Can Am air filter” for $45. Online, the same filter was $28. But the $28 option had a 2-week lead time vs. 2 days. For an emergency replacement, the $45 filter was actually cheaper when I factored in emergency labor costs.
Common Mistakes & Final Thoughts
Here are three mistakes I see contractors make regularly:
- Mistake 1: Focusing on unit price only. A $200 difference on a condenser is irrelevant if the installation costs $500 more or the warranty is worse.
- Mistake 2: Not verifying the model number. I’ve seen “Daikin 7.5 ton package unit” quotes that were actually 6.5 ton units with a different evaporator coil. The price was lower but the performance wasn’t the same.
- Mistake 3: Not documenting the quote. I now require vendors to confirm their quote in writing. If it’s not in an email or a portal, it doesn’t exist. Verbal confirmations have burned me twice.
