If your air conditioner just stopped working (or started making noises that make you nervous) one of the first questions that comes to mind is, “Is my AC unit under warranty?”

It’s a smart question. Because if it is, you could save hundreds (sometimes thousands) on repairs or replacement parts. The challenge is knowing where to look, what’s covered, and how to actually use your warranty when you need it.

At Fairway Heating and Cooling, we’re here to help you make sense of it all; whether you bought your home last week or you’ve been in it for 20 years.

What Kind of Warranty Do AC Units Come With?

Most central air conditioning systems come with two types of manufacturer warranties:

1. Parts Warranty

Covers specific components of the system; things like: 

  • Compressor
  • Coils
  • Fan motor 

These are typically valid for 5 to 10 years, but some brands go longer if you register the unit properly.

2. Labor Warranty

Covers the cost of the technician’s time. Most manufacturers don’t include labor, but Fairway Heating and Cooling offers labor warranty options as part of our service agreements.

You may also have a warranty from the installer — separate from the manufacturer — depending on who put the system in and what kind of plan you purchased at the time.


How to Check if Your AC Unit is Still Under Warranty

Start here:

1. Look for the Serial Number

This is usually found on the outdoor condenser unit. Look for a metal plate or sticker with the manufacturer name, model number, and serial number.

2. Visit the Manufacturer’s Website

Most major AC brands (like Trane, Carrier, Lennox, Rheem, etc.) have online warranty lookup tools. Enter your serial number and you’ll get the warranty start date, duration, and what’s still covered.

3. Check Your Installation Paperwork

If Fairway Heating and Cooling installed your unit, we can pull this info for you. If another contractor did the work, look for receipts, invoice records, or homeowner binders especially if you purchased a new build or recently bought the home.

4. Ask Us

Can’t find it? We’ll help you locate the information. If your system was registered at the time of install, we can track it down. If it wasn’t, we’ll still guide you through your options.


What Happens If It Wasn’t Registered?

Good question, and one we hear often. Here’s the deal:

Many manufacturers require product registration within 30 to 60 days of installation to receive the full parts warranty (usually 10 years). If your system wasn’t registered on time, the default coverage is often just 5 years.

If you didn’t register the system (or you’re not sure) don’t panic. Call Fairway Heating and Cooling and we’ll help figure it out. In some cases, we can still contact the manufacturer or work with you on more affordable repair options.


What’s Usually Covered and What’s Not

Warranties can be tricky, but here’s a quick overview:

✅ Commonly Covered Parts

  • Compressors
  • Coils
  • Blower motors
  • Fan motors
  • Circuit boards

❌ Not Typically Covered

  • Labor (unless you purchased coverage)
  • Refrigerant (depends on the manufacturer)
  • Maintenance-related problems (dirty filters, clogs, etc.)
  • Improper installation or neglect

Want to avoid issues down the line? Regular tune-ups can keep your warranty valid and your unit running smooth. We offer a full maintenance plan for that reason and to catch small problems before they become big ones.
