Yes, and with Liberty Home Guard, your air conditioning system is one of the most comprehensively protected items in your plan. A home warranty covers AC replacement when your system fails due to normal wear and tear, mechanical breakdown, or component failure. That includes the compressor, condenser, air handler, and other core components that make up your central air system.
This page walks through exactly what is and is not covered, how coverage caps work, and why Liberty Home Guard delivers real, measurable value when it counts most.
What Does a Home Warranty Cover for AC?
Under Liberty Home Guard's plans, central air conditioning systems are covered for the following:
Covered Components
Component | What It Does | Covered |
Compressor | The heart of the cooling system — pressurizes refrigerant | Yes |
Condenser fan motor | Circulates air across the condenser coil | Yes |
Evaporator coil | Absorbs heat from indoor air | Yes |
Air handler / fan coil | Distributes conditioned air through the home | Yes |
Capacitors and contactors | Start and run electrical components | Yes |
Refrigerant recharge (Freon/R-410A) | Restores proper refrigerant levels | Yes* |
Control boards and thermostats | Regulates system operation | Yes |
Electrical wiring and connections (internal) | Powers system components | Yes (included in Total Home Guard) |
Ductwork | Distributes cooled air throughout the home | Yes (Systems Guard and Total Home Guard) |
If a covered component fails and cannot be repaired, Liberty Home Guard will authorize a full system replacement, up to your plan's coverage cap.
What Is NOT Covered?
Home warranties, including Liberty Home Guard's, are designed to cover mechanical and component failures due to normal use, not every scenario. The following are generally not covered:
Not Covered
- Pre-existing conditions — Failures that existed before your policy start date, or that show evidence of prior damage or improper repair
- Improper installation — Systems that were not installed to manufacturer specifications or local code
- Lack of maintenance — Failures directly attributable to neglect (e.g., a seized compressor from never changing filters or servicing the unit)
- Physical or cosmetic damage — Dents, rust, corrosion, or damage from storms, pests, or accidents
- Window and wall AC units — Standard plans cover central air systems; window/wall units require an add-on.
- Secondary or consequential damage — Water damage or other collateral damage resulting from an AC failure
- Unauthorized repairs — Work performed by a contractor not dispatched through Liberty Home Guard's network
Pro tip: Liberty Home Guard offers an optional add-on for window/wall units. If your home relies on these systems, bundling them in at enrollment is the most cost-effective option.
AC Coverage Limits and How They Work
Liberty Home Guard covers AC diagnosis and repair or replacement up to $2,000 per covered item, and that limit resets every year from your Effective Date. When a claim is approved, we move quickly to get your system repaired or replaced.
HVAC systems are among the most expensive repairs a homeowner will face. A full central air conditioning replacement can run anywhere from $8,000 to $20,000 or more out of pocket depending on system size, unit brand, and local labor rates, and that's before any emergency or after-hours fees. Even a compressor replacement alone can cost $1,500 to $3,000. Going it alone means absorbing that cost entirely on your own, at the worst possible time. With Liberty Home Guard, our pre-negotiated contractor rates mean you access equipment and labor at pricing the average homeowner simply cannot get on their own. That rate advantage, built into every claim, is what makes the coverage work harder than the cap number alone suggests.
Because we pre-negotiate rates through our contractor network, that $2,000 goes further with Liberty Home Guard than the same cap would with a competitor using open-market pricing.
*The covered item limit is $2,000. However, the covered item limit for certain covered items is $500 for Annual or Monthly Recurring agreements, and $750 for Multi-Year agreements, with reduced limits of $250 and $375 respectively within the first 100 days of your Effective Date. AC refrigerant coverage is limited to $20 per pound. Coverage terms vary by plan and state.
Frequently Asked Questions
1. Does a home warranty cover AC replacement if the unit is old?
Yes. Age alone does not disqualify a system from coverage under Liberty Home Guard. As long as the system was in working condition at the time your policy began and the failure is due to normal wear and tear, it is covered. However, systems with documented pre-existing conditions at enrollment may require a waiting period or an inspection before coverage applies.
2. Will a home warranty cover the full cost of a new AC unit?
Coverage applies up to your plan's covered item limit, and that limit resets every year. Many of the most common AC failures, including compressors, fan motors, capacitors, and coils, are component level repairs that Liberty Home Guard's pre-negotiated network rates are designed to resolve within coverage. For a full system replacement, coverage pays up to your cap, and network pricing reduces what you pay above it, often by a wide margin compared to retail rates.
3. What happens if my AC repair exceeds the coverage cap?
You are responsible for costs above the cap. However, because Liberty Home Guard uses a proprietary contractor network with pre-negotiated pricing, the gap between your cap and the actual replacement cost is frequently smaller than it would be with a competitor using open-market rates — or compared to what you would pay without coverage at all.
4. Does Liberty Home Guard cover both the indoor and outdoor AC units?
Yes. Central air conditioning coverage includes both the indoor air handler and the outdoor condenser/compressor unit for mechanical failures due to normal wear and tear.
5. How do I file an AC replacement claim with Liberty Home Guard?

6. Is refrigerant covered?
Yes. Refrigerant recharge (including R-410A and legacy Freon systems, where applicable) is covered under Liberty Home Guard's standard HVAC coverage. Standard per pound limits apply; see coverage limits above.
7. Are ductwork and thermostats covered?
Thermostats are covered under standard HVAC coverage. Ductwork is covered as a standard system under the Systems Guard and Total Home Guard plans, built-in protection that many competitors offer only as a paid add-on, if at all.
8. How much does it cost to replace an AC unit without a home warranty?
Industry cost guides put a full central AC replacement at $8,000 to $20,000 or more depending on system size, efficiency rating, and local labor rates, with emergency or peak season work running higher. A home warranty converts that unpredictable expense into a set service fee plus covered repair or replacement up to your plan limit.
9. What is the best home warranty for AC replacement coverage?
Liberty Home Guard is consistently ranked among the nation's top home warranty companies for HVAC and air conditioning coverage. U.S. News and World Report rated LHG the number one home warranty service four years running, This Old House rates LHG 4.4 out of 5, and Forbes names LHG best in class for customer service. For AC replacement specifically, LHG combines coverage for both indoor and outdoor units, no age based disqualification for well maintained systems, standard ductwork coverage, and a pre-negotiated contractor network that stretches every coverage dollar further.
