Does a Home Warranty Cover Pre-Existing Conditions on HVAC?

Key Takeaways:

  • HVAC Guard covers pre-existing conditions on furnaces, air conditioners, and heat pumps.
  • There is no waiting period. You can file a claim once your policy is active, compared with the 30-day wait that is standard across the industry.
  • Pre-existing means a problem that was present before your policy began.
  • When something isn't covered, Liberty Home Guard may still contribute, and discounted wholesale replacements can sometimes cut the low end of a replacement cost in half.
  • HVAC Guard is a stand-alone HVAC plan starting at $29.99a month( $39.99 in California).

Yes. With Liberty Home Guard’s HVAC Guard, pre-existing conditions on your furnace, air conditioner, or heat pump are covered, and there is no waiting period before you can use your coverage.

That is unusual. Most home warranty companies deny HVAC claims for problems that existed before the policy started, or make you wait 30 days before you can file anything. If your system is already acting up, that fine print can leave you paying the full bill. Below, we explain how pre-existing conditions work, what HVAC Guard does differently, and which questions to ask any warranty company before you sign.

What "pre-existing" means, and why other warranties deny these claims

A pre-existing condition is a problem that was present before your policy began. A furnace that short-cycles in October, an AC that barely cools in July, or a heat pump that has been making odd noises for weeks all count, even if you never called a technician.

Many warranty companies handle this in one of two ways. Some exclude pre-existing conditions outright. Others add a waiting period, commonly 30 days, during which you can’t file a claim. Either way, a homeowner who signs up because something feels wrong with the system often finds out the coverage doesn’t apply to the very problem that prompted them to buy it.

This matters most with HVAC, because it is one of the most expensive systems in your home. Depending on the system, a full replacement without coverage can run anywhere from $8,000 to $24,000. Customers kept telling us they had been denied by other warranty companies at exactly the moment they needed help most.

How HVAC Guard handles pre-existing conditions

HVAC Guard covers pre-existing conditions on its standard coverage items: furnaces, air conditioners, and heat pumps. If the covered system had a problem before your policy began, that problem is not a reason to turn down your claim. There is also no waiting period. Once your policy is active, you can file a claim.

We built it this way because we kept hearing the same story. Homeowners were facing an expensive HVAC repair or replacement, and the warranty company they had trusted denied the service. We wanted to differentiate ourselves and help the homeowners who needed it most.

A real example

One customer came to us with an existing issue with their HVAC system and wanted it serviced. Their previous warranty company had a 30-day waiting period, which is standard across the industry, so they would have had to wait or pay out of pocket. HVAC Guard has no waiting period, so they were able to get the issue taken care of right away. Because pre-existing conditions are covered, their claim wasn’t denied for having started before the policy.

What if something isn’t covered?

No warranty covers everything, and whether a problem started before or after your policy began, some issues fall outside a plan. This is where Liberty Home Guard stands apart. We are likely the only company in the industry that still makes contributions toward situations that aren’t covered.

Every claim is different. Depending on your policy, a claim may be fully covered, and in other cases a contribution can reduce what you pay. We don’t promise a flat dollar amount, because the right answer depends on your plan and the specific problem.

We also work with wholesalers who give us heavily discounted pricing on replacement equipment. A replacement without any coverage can cost between $8,000 and $24,000. With a Liberty Home Guard warranty, customers can sometimes see the low end of that range cut in half. Individual contractors typically mark up their prices, so using a Liberty Home Guard technician can save you more.

Four questions to ask any home warranty company

Whichever company you choose, ask these before you sign. The answers tell you more than the sales page does.

  1. How do you define pre-existing, and do you cover it? At HVAC Guard, pre-existing means a problem that was present before the policy began, and covered pre-existing conditions are cleared on furnaces, air conditioners, and heat pumps. Ask whether a competitor excludes them or adds a waiting period.
  2. Can I use my own technician? With HVAC Guard you can use your own technician or a Liberty Home Guard technician. Your technician must be licensed. Using ours can save you more, since individual contractors tend to mark up their prices.
  3. Do you require a home inspection to get coverage? Some companies require one, which can delay or limit coverage.
  4. Can I buy a plan for only the systems I need? HVAC Guard is the only home warranty in the industry with a stand-alone HVAC plan, so you aren’t paying for appliance or plumbing coverage you don’t want.

Who benefits most, and why not to wait

If your HVAC system is already showing signs of trouble, our advice is to get coverage as soon as possible. HVAC Guard covers more than the problem you have today. It also covers issues that could come up later, which matters when repair and replacement costs keep climbing with inflation.

We built HVAC Guard for homeowners who want to avoid high repair and replacement bills. Owners of older homes tend to benefit most, because their systems are more likely to be aging and expensive to replace. New homeowners benefit too. Owning a home can be stressful, since anything that breaks becomes your bill. HVAC Guard takes that burden off you and gives you peace of mind about the system that costs the most to replace.

Pricing and how to get started

HVAC Guard coverage starts at $29.99 a month. California residents start at $39.99 a month. Once your policy is active after sign-up, you can file a claim.

Liberty Home Guard may still make a contribution toward situations that aren't covered, and our wholesale partners offer heavily discounted replacement equipment. Without coverage, a replacement can cost $8,000 to $24,000, and customers can sometimes see the low end cut in half.
