The five most common mistakes homeowners make — and exactly why they burn people:

1. Not documenting system condition at policy start. Take photos of your HVAC unit, water heater, appliances before the policy starts. Write down their age and condition. One Reddit user from Tennessee said: ‘I called to activate my warranty and the agent
said my AC was “pre-existing” even though it was only 8 years old and working fine. I had no photos, so I lost the $8,000 claim.’ Once you’re denied for pre-existing, it’s nearly impossible to appeal.

2. Skipping annual HVAC maintenance. Warranty companies use “lack of maintenance” as a denial reason. Your service records are your proof. One homeowner said: ‘I got denied because I didn’t have maintenance receipts. Never again — now I keep every HVAC bill in a folder.’ Keep a folder (physical or digital) with all service records. $150 maintenance visit saves you $5,000 claim denial.

3. Choosing the cheapest plan by premium alone. You’ll regret it when you hit the $250/item coverage cap. Reddit thread from r/Homeowners: ‘I saved $8/month with the bare-bones plan. Then my water heater died and they said $250 max. Cost me $1,100. I
paid $96 to save $96 — worst trade ever.’ Spend 10 minutes comparing coverage limits, not just premiums.

4. Filing the claim too late. Most providers have a 24-48 hour window from when you discover the problem. Another Reddit story: ‘My AC died on a Friday. I called Monday thinking I’d have the weekend. They said I was outside the window and denied it. Cost me $3,200.’ Call the same day the system fails.

5. Accepting a verbal denial without asking for written explanation. Verbal denials can’t be appealed. Written ones can. One homeowner said: ‘They told me no over the phone. I asked for it in writing. Turns out the agent was wrong — they reversed the decision.’ Always say: ‘Please email me the denial reason in writing.’
