Cheapest checks first
It asks about voltage, filters, breakers and valves before anything expensive, because that is genuinely where most problems end. A tool that jumps straight to "you need a new compressor" is selling, not diagnosing.
How It Works
Built from real service calls
Every path in this tool comes from problems we actually diagnose, in roughly the order we actually check them.
Honest about DIY
Where a repair is safe to do yourself, it tells you and explains how. Where it is not — anything involving capacitors, LP gas, or a breaker that keeps tripping — it says so plainly and explains the risk.
Flags the dangerous ones
Some answers stop the tool cold: repeated breaker trips, an ammonia smell from the refrigerator, low-voltage A/C operation. In those cases the right advice is to stop, not to keep troubleshooting.
What Happens Next
Your answers come with you
If the troubleshooter concludes you need a technician, booking from that screen carries your whole diagnostic path into the request — the system, the symptom, and everything you have already ruled out.
That matters more than it sounds. A large share of every service call is spent establishing what you have already tried. Arriving with that known means we start diagnosing rather than interviewing, and you are not paying for the same conversation twice.
- We know which system and symptom before we arrive
- We know what you have already checked, so we don't repeat it
- We can bring the likely parts on the first visit
- Nothing gets lost between your description and the technician
Still stuck?
If your problem doesn't match anything here, or you'd rather just describe it in your own words, call us or use the chat assistant in the corner of the screen.
We would rather talk you out of a service call you don't need than sell you one you do not.

Questions
About This Tool
No, and it says so. It reflects the most common causes we see in the field and will get you to the likely answer quickly, but a tool cannot measure voltage, test a capacitor, or read a moisture meter. Where a hands-on diagnosis is genuinely needed, it tells you that instead of guessing.
Yes. Where a fix is safe and straightforward — a dirty filter, a tripped GFCI, a battery disconnect left off, a dry P-trap — it says so and walks you through it. That costs us service calls, and we would rather have your trust.
Your answers travel with the booking. Your technician arrives already knowing the symptom, what you have ruled out, and what you have already tried, which usually shortens the visit.
It covers the seven systems that account for the large majority of service calls: air conditioning, electrical, plumbing, holding tanks, refrigeration, slide-outs, and water leaks. If your problem is not represented, call us and describe it.
Yes. Certain answers — a breaker that trips repeatedly, an ammonia smell from the refrigerator, running an air conditioner on low voltage — stop the troubleshooter and tell you to stop what you are doing. Those are situations where continuing causes real damage or real risk.
