The first few weeks of homeownership can be exciting—but also overwhelming. As you settle in, you may start noticing issues that didn’t show up during the final walkthrough. It’s common, and that’s where your home warranty may come in handy.

But first, you need to know what to look for.

From plumbing to HVAC, here are some of the most common warning signs new homeowners should watch for in their major home systems—and what to do if they appear.

1. Septic System Trouble

If your home uses a septic system, it’s important to stay ahead of potential clogs and overflows. Most systems need to be pumped every 2–3 years, depending on size and usage.

Warning signs of septic issues:

  • Gurgling noises in your drain pipes
  • Unpleasant sewage odors in the yard
  • Slow draining sinks, especially those on lower levels

If you notice any of these, don’t wait—call a septic professional immediately.

2. Electrical System Issues

Older homes often have outdated electrical systems not designed for today’s power-hungry appliances. If your home has 60-amp service or an old panel, it may struggle to keep up.

Watch for these signs of electrical trouble:

  • Frequently tripping circuits
  • Rust or corrosion on the electrical box
  • Soot around electrical outlets
  • Outlet covers that feel warm
  • Flickering or dimming lights when major appliances run

If you see these signs, contact a licensed electrician to assess the system.

3. Plumbing Leaks and Pipe Damage

Old or neglected plumbing can lead to serious issues like mold, water damage, and even pest infestations. Homes with galvanized pipes are especially at risk.

Key signs of plumbing problems:

  • Water stains under sinks or on ceilings/walls
  • Musty odors or visible mold
  • Running water sounds when everything’s off
  • Persistent moisture or dripping

Try this test: Shut off all water sources and watch your water meter for 30 minutes. If it moves, you likely have a leak.

Don’t delay—call a plumber to prevent further damage.

4. HVAC System Problems

Your HVAC system keeps you comfortable—but only if it’s been properly maintained. Neglect from previous owners (like skipped tune-ups or filter changes) can lead to inefficiency or outright failure.

Signs your HVAC system is struggling:

  • Blowing air, but it’s not hot or cold
  • Unit won’t turn on
  • Strange odors or noises when it kicks on

If you notice these symptoms, call an HVAC technician before the seasons shift.

Check Your Home Warranty Coverage

If you’re spotting issues in your home’s systems, don’t panic—check your home warranty first. Your policy may cover many of these problems, but time is key: most coverage windows start at closing and can expire quickly.

Contact your warranty provider to:

  • Review your coverage
  • Request service
  • Get help connecting with trusted professionals
