What to Ask an HVAC Company Before You Sign
Before you sign an HVAC contract in Indianapolis, ask for Manual J assumptions, duct findings, who pulls the mechanical permit, itemized Good/Better/Best options, warranty registration terms, and what is excluded from the price. Pressure to “sign today for a special” is a red flag — not a value-add. A solid Central Indiana contractor can answer these calmly overnight; urgency theater usually hides thin scopes. Identical brand names on two quotes can still hide wildly different duct, electrical, and permit work — so compare scope line by line before you commit.

- Ask who pulls the permit and who meets the inspector.
- Ask to see load and duct notes — not just a brand brochure.
- Ask what is excluded: electrical, condensate, permit fees, disposal.
- Ask how change orders are priced and approved in writing.
- Ask whether the crew is W-2 or subcontracted for your install.
After you have one or more quotes in hand
Use this list at the kitchen table — or bring the quotes to a Free Second Opinion so someone compares scopes without the original salesperson’s clock running. Walk every Indianapolis quote against the same written checklist so brand names cannot hide missing ducts, permits, or exclusions.
When the pitch leans on today’s-only pricing
Good scopes survive overnight thinking. If answers get vague when you ask about permits, ducts, or exclusions, slow down before you sign. Walk every Indianapolis quote against the same written checklist so brand names cannot hide missing ducts, permits, or exclusions.
Comparing Good/Better/Best packages
Ask what changes between tiers besides the outdoor unit sticker — airflow, filtration, labor warranties, and commissioning steps should be explicit. See /process/good-better-best. Walk every Indianapolis quote against the same written checklist so brand names cannot hide missing ducts, permits, or exclusions.
How it works
Scope questions that prevent change-order pain
Confirm equipment models, duct repairs, electrical, thermostat, condensate, pad, line-set reuse vs replacement, disposal, and permit. If it is not written, assume it is not included. Get answers in writing overnight if needed — solid Central Indiana contractors can wait while urgency theater usually cannot.
Process questions that predict the install experience
Timeline, crew structure, warranty registration, startup/commissioning checklist, and who to call if something fails on night one. Vague process answers predict vague accountability. Get answers in writing overnight if needed — solid Central Indiana contractors can wait while urgency theater usually cannot.
Technical questions that protect comfort
Manual J assumptions, static-pressure or duct notes, and how upstairs or basement rooms will be verified after install. Central Indiana humidity makes “thermostat hit setpoint” an incomplete success metric. Get answers in writing overnight if needed — solid Central Indiana contractors can wait while urgency theater usually cannot.
Use a written checklist
Print or save /second-opinion-checklist and walk each quote against it. Identical brand names can hide wildly different duct and permit scopes. Get answers in writing overnight if needed — solid Central Indiana contractors can wait while urgency theater usually cannot.
What goes wrong when this is ignored
Signing under artificial urgency
Good scopes survive overnight thinking. Same-day pressure often protects the salesperson’s calendar more than your comfort. Slow down until scope, permit ownership, and change-order rules are explicit on the contract you sign. Confirm details on site for your address and equipment.
Comparing price without comparing exclusions
The lowest number can omit permits, electrical, or duct repairs you will still need. Apples-to-apples scope beats sticker shopping. Slow down until scope, permit ownership, and change-order rules are explicit on the contract you sign. Confirm details on site for your address and equipment.
Skipping who owns the permit
Unpermitted work shows up in real estate transactions and insurance claims. Ask who pulls it — and get it in writing. Slow down until scope, permit ownership, and change-order rules are explicit on the contract you sign. Confirm details on site for your address and equipment.

Frequently asked questions
What is the single most important question before I sign?+
Ask for Manual J assumptions and duct findings in writing, plus who pulls the mechanical permit. If those answers are fuzzy, the price is not trustworthy yet. Bring the quote to a Free Second Opinion.
How do I use a second-opinion checklist without insulting my contractor?+
Frame it as due diligence for a long-lived purchase. Professional contractors expect scope questions. The Act checklist lives at /second-opinion-checklist; Evaluate context: /evaluate/hvac/when-second-opinion-matters.
Should every quote include Good, Better, and Best options?+
Not every job needs three tiers, but you should understand what changes when price changes — equipment stage, filtration, duct work, and warranties. See /process/good-better-best for how LCS frames that conversation.
What warranty questions actually matter?+
Ask who registers the manufacturer warranty, what labor coverage you get and for how long, and what maintenance is required to keep coverage valid. “Lifetime” language without details is not enough.
Can I negotiate after the salesperson leaves?+
You can always ask clarifying questions and request written revisions. What you should not do is accept a thinner scope to chase a lower number without understanding what was removed.
