ADT Salesperson Just Showed Up — Here's What Buyers Need to Know

Authorized dealer vs. ADT Corporate

ADT sells through both direct employees (ADT Corporate) and an authorized dealer network. Dealers can use ADT branding and sell ADT systems, but they are independently owned businesses. The rep at your door may or may not be an ADT employee. Ask directly — the answer affects who is accountable for your installation and what recourse you have if something goes wrong.

The 36-month contract

ADT professionally installed plans require a 36-month monitoring contract. If you cancel before 36 months, the early termination fee is approximately 75% of your remaining contract balance. This is a binding contract term, not a negotiating point at the door. A 36-month contract at $52.99/month = $1,907.64 in monitoring commitments. Know what you're signing before you sign it.

The rate-variation risk

ADT monthly rates vary by region, promotion, and dealer. The rate the rep quotes verbally and the rate in the contract can differ — the contract rate is what you're actually agreeing to. Always read the monitoring fee in the contract before signing. Also ask whether the rate is locked for the full 36-month term or subject to annual increases.

The FTC Cooling-Off Rule protects you for 3 business days

For any in-home sale of $25 or more, federal law gives you 3 business days to cancel without penalty. ADT is required to provide written notice of this right at the time of sale. If you signed today and change your mind, this law applies — invoke it in writing immediately. Send a written cancellation notice by certified mail to both ADT and the dealer (if applicable).

In the next 15 minutes

1. Ask for the full written quote — monitoring rate, contract length, equipment cost, ETF formula, and installation fee. In writing, not verbal
2. Ask: "Are you an ADT employee or an authorized dealer?" Get the dealer company name if applicable
3. Take a photo of any documents shown to you before signing anything
4. Say this: "I need 24 hours to review this before I decide." You don't need a reason
5. Do not allow installation to begin — once installation starts, unwinding becomes significantly more difficult

In the next 24 hours

1. Decode the quote with our Quote Decoder — verify whether the pricing matches what ADT publishes at ADT.com
2. Calculate the ETF at every stage of the contract — use our ETF Calculator to see what canceling would cost at month 6, 12, 18, and 24
3. Verify the monitoring rate in the written contract — the contract rate is what you're agreeing to, not the verbal quote
4. Read our ADT contract length guide — understand what the 36-month commitment means in practice before you sign
5. Compare no-contract alternatives — SimpliSafe, Ring, and Cove offer professional monitoring with no long-term commitment. Know the trade-off before deciding

In the next 72 hours

1. If you want to sign: run the ETF Calculator one more time with the exact numbers from the contract — know the worst-case exit cost before you commit
2. If you already signed: the FTC Cooling-Off Rule gives you 3 business days — send written cancellation by certified mail to ADT and the dealer immediately if you have any doubt
3. Request ADT's 6-month money-back guarantee terms in writing — professionally installed plans include this, but terms can vary by dealer
4. Read the full service agreement — including the rate increase clause and the ETF calculation formula. The summary sheet is not the contract

Assuming the rep is an ADT employee

ADT's dealer network is large and active. The rep at your door may be employed by an independent company with ADT authorization, not by ADT Corporate. This affects complaint resolution, post-install accountability, and who you call if something goes wrong. Always ask directly, and get the dealer company name in writing if they are not ADT Corporate staff.

Not calculating the ETF before signing

ADT's ETF is approximately 75% of your remaining contract balance — not a flat fee, and not a small amount in the early years. At month 6 of a 36-month contract at $52.99/month, you would owe roughly (30 × $52.99 × 0.75) = $1,192 to cancel. This is not an edge case — it's the standard exit cost for early cancellation. Calculate this before you sign.

Trusting the verbal rate over the written contract rate

ADT rates vary by region, promotion, and dealer. If the verbal quote and the contract show different numbers, the contract governs. Read the monitoring fee in the service agreement itself — not just the quote summary — before signing. If the numbers don't match what you were told, ask for a written addendum before proceeding.

Not using the FTC Cooling-Off Rule after signing under pressure

Federal law gives you 3 business days to cancel any in-home sale. ADT is required to provide written notice of this right at time of sale — if they didn't, the window may extend further. If you signed under pressure and changed your mind the next morning, this law is available to you. Use it. Send written cancellation by certified mail immediately and do not wait for a phone response.

ADT equipment doesn't transfer to other providers

ADT professionally installed equipment is proprietary. If you cancel ADT, your existing sensors and keypads cannot be reprogrammed for SimpliSafe, Ring, or any other provider — you'll need new equipment when switching. Factor equipment replacement cost into your total analysis if comparing ADT against a DIY alternative.
