The contract you sign is the only document that determines what's actually covered. Marketing materials, sales calls, and even customer service statements don't override the written contract. Reading it before filing a claim - ideally before purchasing - is the most important thing you can do to protect yourself.
The 8 Key Contract Sections
Definitions
How every other section is interpreted.
Watch for how the contract defines "mechanical failure," "normal wear and tear," "pre-existing condition," and "covered component." The word "discoverable" in the pre-existing condition definition is particularly dangerous - it lets companies exclude conditions you didn't actually know about.
Watch for: "Reasonably discoverable" in pre-existing definition - expands exclusion beyond what you knew
Coverage (What's Covered)
The system list and the components list.
Most disputes involving "non-covered components" trace to this section. The system may be covered but the specific failed part isn't listed. Example: HVAC covered, but thermostat wiring not in the components list = not covered.
Watch for: System listed as covered doesn't mean every component within it is covered
Coverage Limits (Caps)
Maximum payout per item and per year.
The HVAC cap is the most important number. $1,500 vs. $6,500 is the difference between meaningful protection and a gap payer. An aggregate annual limit below the HVAC cap means one HVAC claim wipes out all other coverage for the year.
Watch for: Aggregate annual limit lower than HVAC cap - one claim eliminates all other coverage
Exclusions (What's NOT Covered)
Often the longest section - and the most important.
Universal exclusions (pre-existing, improper installation, cosmetic, secondary damage) appear in every contract. Company-specific exclusions vary. AHS covers rust/corrosion; most don't. Read every item on the exclusions list before buying.
Watch for: Rust/corrosion exclusion in humid markets = significant HVAC exposure
Service Fee Terms
What you pay per service call and when.
Per-visit vs. per-item matters when a tech inspects multiple systems in one visit. Most contracts state the service fee is non-refundable even if the claim is denied - standard and generally enforceable. Most companies collect the fee when scheduling, not at repair completion.
Watch for: Service fee non-refundable even on denied claims - standard but worth knowing
Contractor Terms
Who can do the work.
Most contracts require company-authorized contractors only. Work by unauthorized contractors may void coverage for that item. Better contracts include emergency authorization language and a 30–90 day workmanship guarantee on completed repairs.
Watch for: Using an unauthorized contractor - even in an emergency - may void coverage
Term, Renewal, and Cancellation
How the contract starts, continues, and ends.
The 30-day waiting period at policy start is when most companies can deny claims as pre-existing. Auto-renewal language governs whether your rate can increase at renewal without clear disclosure. Cancellation rights include the refund formula - usually prorated minus a cancellation fee.
Watch for: Waiting period: claims in first 30 days are vulnerable to pre-existing condition denial
Dispute Resolution (Arbitration Clause)
The section most homeowners never read.
Mandatory binding arbitration waives your right to sue in court, specifies which arbitration organization applies, and typically includes a class action waiver. Once you've filed a claim dispute, this section controls your options.
Watch for: Class action waiver - you cannot join or bring a class action lawsuit
Contract Language Red Flags
Company has final word on coverage decisions without objective standards
Expands pre-existing exclusion beyond conditions actually known to you
One HVAC claim eliminates all other coverage for the year
Company can replace premium systems with builder-grade equivalents
Company can assess and declare systems pre-existing early in the term
How to Actually Read the Contract

Most companies offer this on their website before purchase. If you can't find it, ask for it before signing anything.
Read the definitions section first
The definitions control how everything else in the contract is interpreted. Pre-existing condition, mechanical failure, covered component - read these carefully.
Read the exclusions section in full
Every item on that list is something the company will not pay for. The surprise exclusions are almost always visible in the contract.
Find the HVAC cap and the aggregate annual limit
These two numbers determine your maximum financial protection and exposure. They're the most important numbers in the contract.
Read the arbitration clause
You'll find it near the end. Understand what rights you're waiving before you sign.
