1) Trip / service-call fees

• The guarantee applies to labor for diagnosis/repair, not travel. Any posted trip/service-call fee is still due.

2) Parts & materials

• If parts, materials, refrigerant, sealants, fluids, hardware, etc. are installed or ordered, those costs are still owed (even if the overall problem isn’t fully resolved).

3) Pre-approved work / partial repairs

• If you approve and we complete any specific repair, that completed work is billable—even if it later turns out there are additional issues beyond that repair.

4) Customer declines recommended repair

• If we diagnose the issue and you decline the recommended fix (or stop work), the guarantee doesn’t apply.

5) Unsafe or inaccessible conditions

• No guarantee when the work area is unsafe or inaccessible (roof hazards, mold/sewage exposure, severe corrosion, aggressive pets, no safe jacking points, unstable ground, etc.).

6) Lack of required utilities

• If we can’t properly test due to missing utilities (no power, dead batteries, no propane, no water supply, empty fuel, etc.), the guarantee doesn’t apply.

7) Intermittent / non-reproducible problems

• If the symptom can’t be reproduced during the visit (intermittent faults, “only happens while driving,” rare electrical glitches), we can’t guarantee a fix.

8) Hidden damage / pre-existing conditions

• Water intrusion, rot, previous DIY work, rodent damage, burnt wiring, multiple failures, or concealed issues discovered during service may fall outside the guarantee.

9) Prior modifications or non-standard installs

• Aftermarket mods, custom wiring, and non-OEM installs can limit what we can diagnose/repair on-site.

10) Manufacturer defects, recalls, and warranty-only work

• Issues that require dealer-only tools, factory authorization, or warranty/recall processing aren’t covered by the guarantee.

11) Systems beyond practical field repair

• Some items require shop-level equipment (certain AC sealed-system work, major structural repairs, frame damage, etc.). If it’s not realistically field-repairable, it’s excluded.

12) Follow-up issues not related to our work

• New problems that appear after the visit (or unrelated systems) are not covered.

13) Customer-provided parts

• No guarantee on customer-provided parts (wrong part, poor quality, missing components, compatibility issues).

14) Emergency / after-hours service

• If you offer after-hours/holiday emergency calls, you can exclude those from the guarantee (or limit it).
