How Do I Check to See If My HVAC Unit Is Still Under Warranty?

Determining whether your HVAC unit is still under warranty can save you time and money on repairs and replacements. However, the process can be confusing if you're unsure where to start. Here's a step-by-step guide to help you find out if your HVAC system is still covered under warranty.

1. Locate the Unit's Serial and Model Numbers

The first step in checking your warranty status is to locate the serial and model numbers of your HVAC unit. These numbers are typically found on a nameplate or label attached to the unit, often on the outdoor condenser or indoor air handler. The serial number usually contains information about the unit's manufacturing date, which can help determine the warranty period.

2. Review Your Owner’s Manual and Warranty Documents

If you still have the owner’s manual and warranty documents that came with your unit, review them carefully. These documents often outline the warranty terms, including the duration of coverage and what components are covered. If you’ve misplaced these documents, you may be able to find them online on the manufacturer's website or by contacting the company directly.

3. Contact the Manufacturer

You can contact the manufacturer’s customer service department directly to inquire about your unit's warranty status. Provide them with the serial and model numbers, and they should be able to look up your unit’s details and confirm whether it is still under warranty. Many manufacturers also have online tools or portals where you can enter your unit’s information to check warranty status.

4. Check With Your HVAC Installer or Dealer

If you purchased your HVAC system through an installer or dealer, they might have records of the purchase and installation date. Contact them to inquire about the warranty status. They may also offer additional warranty coverage or service plans that could be relevant.

5. Look for Extended Warranty Information

In addition to the standard manufacturer warranty, you may have purchased an extended warranty at the time of installation. Check your purchase records or contact the dealer to see if an extended warranty applies. Extended warranties often cover additional components and labor costs that may not be included in the standard warranty.

6. Determine the Type of Warranty Coverage

It’s essential to understand the different types of warranties that may apply to your HVAC unit. Common types include:

  • Manufacturer’s Warranty: Typically covers parts and sometimes labor for a specified period.

  • Labor Warranty: Covers labor costs associated with repairs, often provided by the installer or dealer.

  • Extended Warranty: Additional coverage that extends beyond the standard warranty period.

7. Consider Warranty Registration Requirements

Some manufacturers require warranty registration within a certain period after installation to activate the warranty. If you're unsure whether your unit was registered, check with the manufacturer or installer. Failure to register your unit could result in a shorter warranty period or limited coverage.

Conclusion

Checking whether your HVAC unit is still under warranty is a straightforward process that can provide peace of mind and potential savings. By gathering the necessary information and contacting the relevant parties, you can quickly determine your warranty status and understand your coverage options.

  • Why is water leaking from my indoor AC unit?
    Water leaks usually mean your drain line is clogged. In Fort Myers, algae builds up quickly due to humidity. We clear clogs and install float switches or access panels to prevent water damage in the future.
  • What should I check if my AC stops working?
    Start by checking your thermostat settings, breaker panel, and drain line. If everything looks normal and your AC still won’t turn on, call Big Air AC — we specialize in fast, reliable AC repair in Fort Myers.
  • Why does my AC blow warm air during the afternoon?
    This can happen when your AC is low on refrigerant, overheating, or undersized for your home. Fort Myers heat puts extreme stress on systems. We’ll diagnose the issue and recommend the best solution.
  • Why is my AC running but not cooling my house in Fort Myers?
    If your air conditioner is running but not cooling, it could be low on refrigerant, have a dirty coil, or a clogged drain line. These are common issues in Fort Myers due to heat, humidity, and algae buildup. We offer fast diagnostics to get your system cooling again.
  • What’s a normal AC temperature split in Fort Myers?
    A healthy system should have a temperature split (difference between return and supply air) of 18–22°F. If your TD is low, it could mean poor airflow, low refrigerant, or a dirty coil. We measure this on every call.
  • Can high humidity cause my AC to stop cooling?
    Yes. High humidity lowers your system’s ability to cool and dehumidify effectively. We measure the temperature differential (TD) and humidity levels at each call to catch this early.
  • Why does my AC blow warm air in the afternoon?
    If your AC works in the morning but blows warm later, it may be overheating, low on charge, or undersized for your home. Fort Myers afternoon heat puts massive strain on systems, especially older or improperly installed units.
  • Why is my AC running but not cooling the house?
    This is one of the most common issues in Fort Myers. It could be: Low refrigerant A dirty evaporator coil A clogged drain line tripping the float switch A failing capacitor or compressor We run full diagnostics and show you real-time readings so you know exactly what’s wrong.
  • Does the salt air near the coast wear out AC systems faster?
    Yes. Homes near the water often see corrosion on condenser coils and electrical components. Coastal homes benefit from protective coatings, routine rinsing, and more frequent inspections.
  • How long should an AC last in Fort Myers?
    Due to Florida’s heat, humidity, and salt in the air, most AC systems in Fort Myers last 10–15 years with regular maintenance. Without service, lifespan drops quickly. We help homeowners extend the life of their system with professional tune-ups and cleanings.
  • What can I do to make my AC last longer in Southwest Florida?
    The key is preventative maintenance. Clean filters, annual coil cleanings, and refrigerant checks reduce wear and tear. We also recommend installing surge protectors to protect electronics from Florida’s frequent lightning strikes.
  • What kind of warranty comes with a new AC installation?
    Every system we install includes a 1-year labor warranty and a 10-year parts warranty backed by the manufacturer. That means if anything goes wrong, you're covered — both for peace of mind and long-term protection. We handle the warranty registration for you, so you don’t have to lift a finger.
  • Do you offer financing or rebates for new HVAC systems?
    Yes! We offer affordable financing and can help you take advantage of utility rebates or manufacturer incentives when you upgrade to a high-efficiency AC system in Fort Myers.
  • Is it better to repair or replace my AC system?
    If your system is just old, but working fine, we would say just let it ride. If it needs frequent repairs, or struggles to keep up in the Fort Myers heat, replacement is often the smarter long-term move. We’ll walk you through your options and help you compare the cost of repairs vs. upgrading to a more efficient system.
