Occupant comfort depends on your mechanical designs. When HVAC systems can't cope or ventilation proves inadequate, Professional Indemnity insurance is what stands between you and a claim that your engineering failed to perform.

Comfort Expectations

Building occupants expect comfortable temperatures year-round. When your HVAC design can't maintain conditions during extreme weather, complaints immediately focus on the mechanical engineering. Rectification in occupied buildings is expensive and disruptive - and the finger points at the designer first.

Energy Performance

Sustainability commitments and energy ratings depend on mechanical system performance. When energy consumption exceeds predictions or buildings don't achieve their ratings, owners may seek to recover costs from the engineer. A solid PI policy is your first line of defence.

WHY TANK INSURANCE

What to look for in PI cover

Mechanical engineering involves systems that directly affect occupant experience - comfort, air quality, energy use. The liability exposure is real, and we arrange cover that addresses HVAC design claims, ventilation failures, and energy performance disputes. See our broader engineers insurance guide for context across disciplines.

Building HVAC representing mechanical engineer professional liability

01

Building Services Expertise

We work with insurers who understand mechanical engineering in buildings - HVAC design, ventilation requirements, and the types of claims that arise from system underperformance.

02

Energy Performance Cover

Sustainability targets and energy ratings create specific exposures. We work to make sure your policy covers claims arising from energy prediction inaccuracies and missed NatHERS or Green Star targets.

03

Occupied Building Claims

Mechanical failures in occupied buildings are immediately visible to tenants and owners. We arrange cover that addresses claims for discomfort, remediation costs, and business disruption.

04

EA & Registration Compliance

We work to confirm your policy meets Engineers Australia requirements and professional registration expectations in your state.

PROFESSIONAL RISKS

Risks Mechanical Engineers Face

These mechanical system design decisions carry professional liability when buildings don't achieve comfort, ventilation, or energy performance targets.

HVAC systems failing to achieve design temperatures
Ventilation design inadequate for occupancy or use
Energy consumption exceeding design predictions
Acoustic performance of mechanical systems unsatisfactory
Vertical transport design causing waiting time issues
Refrigeration system specifications failing requirements
Plant room coordination issues with other services
Sustainability targets not achieved by mechanical design

Occupants notice when mechanical systems underperform. PI insurance protects you when comfort complaints become professional claims.

COVERAGE DETAILS

What Mechanical Engineer PI Insurance Covers

Professional Indemnity insurance for mechanical engineers covers claims arising from your HVAC, ventilation, and mechanical system design services.

Commercial building representing mechanical engineer PI coverage
Commercial building representing mechanical engineer PI coverage

Usually Covered

✓ Legal defence costs when mechanical designs are challenged
✓ Claims for HVAC systems failing temperature requirements
✓ Ventilation design inadequacy allegations
✓ Energy performance not meeting design predictions
✓ Mechanical noise complaints and acoustic failures
✓ Vertical transport design claims affecting building function

Not Typically Covered

✕ Installation workmanship failures (contractor's liability)
✕ Deliberate design non-compliance with codes
✕ Known design issues not disclosed at policy inception
✕ Equipment product failures (manufacturer's liability)
✕ Physical damage during site work (Public Liability)
✕ Maintenance failures after handover (owner's responsibility)

Mechanical engineering claims often involve arguments about design conditions versus actual operation. We help you understand what your policy does and doesn't cover.

QUESTIONS

Frequently Asked Questions

Mechanical engineer PI insurance covers claims arising from your HVAC, ventilation, lift, and mechanical system design services. If your designs don't achieve thermal comfort, energy targets, or ventilation requirements, PI cover can respond to professional negligence claims.
HVAC systems that can't maintain design temperatures during extreme weather are common claims. Ventilation systems that don't meet fresh air requirements, energy consumption exceeding predictions, and mechanical noise complaints also generate significant claims.
Mechanical engineers provide design and advisory services - they don't install systems. Your exposure is for design errors and specifications, not installation workmanship. HVAC contractors need trade insurance covering their installation work; engineers need PI covering their designs.
$2M-$10M is typical for mechanical engineers. Large commercial buildings with complex HVAC systems may require higher limits. Rectifying underperforming mechanical systems in occupied buildings can be expensive and disruptive.
Yes, energy modelling and sustainability design services are covered. If your energy predictions prove materially wrong or buildings don't achieve sustainability targets, claims can arise. This is a growing area of exposure worth reviewing with your broker.
