Does a home inspection include an HVAC inspection? #

Yes. A standard home inspection typically includes a visual and operational inspection of the home’s heating and cooling systems. The inspector will operate the system using normal controls and evaluate its general condition, performance, and visible components.

What HVAC components are typically inspected? #

During a home inspection, the inspector may evaluate:

• Heating equipment such as furnaces, boilers, and heat pumps
• Central air conditioning equipment
• Thermostats and normal operating controls
• Visible ductwork and distribution systems
• Air handlers and accessible components
• Visible condensate drain lines
• Supply and return air registers
• General installation and maintenance conditions

The goal is to identify readily observable deficiencies and safety concerns.

How do inspectors test the heating system? #

The heating system is typically operated using the thermostat and normal controls. The inspector will verify whether the system responds appropriately and produces heat.

Depending on the system type, observations may include:

• Burner operation
• Unusual noises or vibrations
• Signs of corrosion or damage
• General equipment condition
• Visible safety concerns

How do inspectors test the air conditioning system? #

When outdoor temperatures permit, the cooling system is operated through normal controls to verify basic functionality.

Inspectors may observe:

• Whether cool air is being produced
• Temperature differential between supply and return air
• Equipment operation and response
• Visible condition of the outdoor condenser unit
• Signs of deferred maintenance

Do inspectors measure refrigerant levels? #

No. Home inspectors do not typically connect gauges or test refrigerant pressures.

Measuring refrigerant levels requires specialized tools and licensing and is outside the scope of a standard home inspection.

Do inspectors disassemble HVAC equipment? #

No. Home inspections are non-invasive.

Inspectors do not dismantle equipment, remove sealed panels, perform repairs, or conduct destructive testing. The inspection is limited to readily accessible components and normal operating controls.

Can a home inspection determine the remaining life of an HVAC system? #

No inspector can accurately predict exactly how long an HVAC system will last.

However, inspectors may comment on:

• Approximate equipment age
• Visible condition
• Signs of deferred maintenance
• Indicators that replacement may be approaching

Even a well-functioning system can fail at any time due to age, wear, or unforeseen conditions.

What are common HVAC issues found during home inspections? #

Common findings include:

• Dirty or clogged air filters
• Deferred maintenance
• Corrosion or rust
• Damaged insulation on refrigerant lines
• Improper condensate drainage
• Inoperative thermostats
• Older equipment nearing the end of its typical service life
• Airflow concerns
• Missing service records

When should I consider a specialized HVAC inspection? #

A specialized HVAC inspection may be appropriate when:

• The equipment is older
• Significant defects are observed
• The property contains multiple HVAC systems
• The building is large or complex
• You want a more detailed assessment before purchasing

A specialized HVAC inspection is typically performed by a licensed and insured HVAC contractor who can evaluate refrigerant levels, electrical components, system efficiency, and other technical aspects beyond the scope of a standard home inspection.

Does a home inspection guarantee future HVAC performance? #

No. A home inspection provides an assessment of the HVAC system’s condition and operation at the time of the inspection only.

No inspection can guarantee future performance, reliability, efficiency, or remaining service life.

Why does Arch Inspections evaluate HVAC systems? #

HVAC systems represent one of the largest repair and replacement expenses in a home. Our inspections help buyers and homeowners better understand the visible condition of their heating and cooling equipment so they can make informed decisions about maintenance, repairs, and future budgeting.
