Most first-time AED buyers don’t know which questions to ask — and as a result, end up with the wrong device, expensive surprise consumable costs, or a missing pediatric pad set when a child collapses. These seven questions cover the decision space and force every important trade-off to the surface before purchase, not after.
Question 1 — Indoor or outdoor?
The single biggest device-selection variable. Indoor (offices, schools, indoor zones, retail) works fine with IP21-rated units like Philips HeartStart OnSite. Outdoor (athletic fields, pool decks, marinas, construction trailers) requires IP55+ — Philips FRx (IP55), HeartSine PAD 350P/360P/450P (IP56), ZOLL AED Plus (IP55). Mixed-environment buyers should default to IP55+ for flexibility.
Question 2 — Who will respond?
Trained workplace staff respond differently from panic-likely homeowners. Trained: semi-automatic AEDs work fine (button press = bystander clearance). Untrained-likely: fully-automatic (HeartSine 360P) eliminates a freeze-prone decision. Healthcare clinics with BLS-certified responders should consider clinical-grade (LIFEPAK CR2, Philips FR3).
Question 3 — Pediatric population?
For schools, daycare, family-serving facilities: pediatric pads or pediatric-mode capability required. The simplest pathway is Philips FRx with the Infant/Child Key (single pad set + key). HeartSine offers pediatric PAD-PAK. ZOLL Pedi-Padz II works on AED Plus.
Question 4 — 10-year TCO, not just upfront
Sticker price is half the story. A $1,295 Defibtech Lifeline with 2-year pads costs more across 10 years than a $1,795 ZOLL AED Plus with 5-year pads. Use the AED Cost Calculator to model full ownership. For benchmarks, see our 10-Year Cost article.
Question 5 — State compliance?
Twenty-one states mandate AEDs in K-12 schools. Twenty-four require them in fitness facilities. Twenty-six in dental offices with sedation. Verify with AED Laws by State before purchase — compliance can dictate model class.
Question 6 — Who maintains it?
If you don’t have a facilities team, choose maintenance-simplest. HeartSine PAD-PAK = one cartridge every 4 years. ZOLL AED Plus = 5-year pads. Avoid 2-year pad models (Philips OnSite, Defibtech Lifeline) unless you have someone tracking calendars.
Question 7 — Insurance broker position?
Many commercial insurers offer a 1–3% property/liability premium discount for documented AED programs. Ask before purchase — the discount can fund pads + battery + training for the life of the program. See AED Insurance Coverage.
Frequently Asked Questions
What’s the most important question before buying an AED?
Where it’ll be deployed — indoor or outdoor. That single answer eliminates 50% of the device universe.
Should I ask about pediatric pads if no kids are in my workplace?
Yes — visitor children, family events, and clients with kids count. Pediatric pad capability is cheap insurance.
How much should my AED budget be?
Plan $2,500–$4,500 over 10 years per device, including consumables, training, and cabinet. See the Cost Calculator.
Should I ask my insurance broker before or after purchase?
Before — confirm the premium-discount program requirements so your documentation meets them.
Do I need to involve my state Board of Health?
For schools, dental, daycare, and fitness facilities in mandated states, yes. For general workplaces, registration with local EMS is usually sufficient.
