• Cleanroom HVAC systems

• Process cooling and heat recovery systems

• Dust, fume, and solvent exhaust systems

System selection is based on application criticality, operating cost, reliability, and future scalability.

Yes. Envigaurd undertakes turnkey HVAC and MEP projects, covering HVAC, electrical, plumbing, compressed air, gas pipelines, automation, and validation coordination, ensuring single-point responsibility, faster execution, and coordinated project delivery.

Every project follows a structured methodology:

• Detailed engineering and BOQ freezing

• Approved material submittals

• Factory-fabricated ducting and piping

• On-site quality inspection and testing

• Air balancing, water balancing, and performance verification

• Complete commissioning documentation and handover dossiers

This ensures the system performs as designed and remains audit-ready.

Yes. Energy efficiency is built into our engineering through:

• Optimized heat load calculations

• High-efficiency chillers and AHUs

• VFD-based airflow control

• Heat recovery solutions

• Smart zoning and automation integration

Our approach reduces operating cost, maintenance burden, and long-term power consumption.

We regularly execute HVAC retrofitting, capacity upgrades, and brownfield modifications, including:

• Replacement of outdated AHUs

• Duct redesign for airflow improvement

• Cleanroom revalidation upgrades

• Energy optimization projects

• Integration with running plant operations

All retrofit works are planned to minimize downtime and contamination risk.

Envigaurd executes HVAC projects across Bangalore, Pune, Hyderabad, Chennai, and major industrial hubs in India, supporting both new construction and operational facilities.

Yes. We perform complete HVAC testing and commissioning, including airflow measurement, room pressurization testing, temperature & RH mapping, and system performance verification.
For regulated facilities, we support validation documentation, drawings, and audit readiness.

The best results come when we are involved from the concept or design stage. Early involvement allows us to optimize layout planning, equipment sizing, energy strategy, project cost, and execution timelines—preventing expensive site-level changes later.

Our project execution model includes:

• Approved baseline schedules

• Dedicated site engineers and supervisors

• Weekly progress tracking

• Material planning linked to milestones

• Safety, quality, and coordination reviews

This ensures predictable delivery, controlled cost, and site safety compliance

Yes. We provide AMC services, performance audits, preventive maintenance, and system optimization, helping clients maintain efficiency, compliance, and uptime throughout the HVAC system lifecycle.

You can request a technical consultation, site survey, or HVAC project quotation directly through our website or by contacting our engineering team.
We evaluate your process requirements, building conditions, compliance needs, and expansion plans before proposing a solution.

In pharmaceutical environments, HVAC is a critical quality system, not just a utility. It directly controls air cleanliness, pressure differentials, temperature, and humidity, which impact product quality, cross-contamination control, operator safety, and regulatory compliance.
Envigaurd designs pharmaceutical HVAC systems to maintain classified cleanroom conditions, stable environmental parameters, and audit-ready performance.

Envigaurd offers complete pharmaceutical HVAC contracting, including:

• GMP-compliant HVAC system design

• AHU selection and cleanroom ventilation engineering

• HEPA filtration and terminal air distribution

• Pressure cascade planning

• Installation, testing & commissioning

• Support for DQ, IQ, OQ documentation

• HVAC upgrades and capacity expansions

We support both greenfield pharmaceutical projects and operational plant modifications.

We often worry about the air quality outdoors and choose to wear masks. However, the indoor air can be just as polluted with no way to be recycled. With a high-quality HVAC system in place, you can keep your indoor air quality in check.

HVAC systems tend to fade away with time in terms of efficiency. If your system is older than 15 years, it should be replaced soon to ensure efficiency and better temperature maintenance. Sticking to the old systems could lead to higher energy bills and inefficient temperature maintenance.

While most HVAC systems do not need servicing every now and then, it is important to opt for an Annual Maintenance Service to ensure any abrupt error or damage is corrected with ease.

As per HVAC standards, it is recommended that you opt for air filters that have MERV 6 or a higher marking. Residential systems can do well with MERV 8 to 13 filters, while industries would do well with MERV 14 or higher.

HVAC air filters should typically be replaced every 30 to 60 days depending on the usage. The duration can be longer for commercial-grade filters depending on the usage.

If you are looking for signs to replace your HVAC system, here are a few you need to keep in mind:

• Your HVAC is 15 years or older
• Repair cost is higher than half the original cost of the system
• Ever-increasing energy bills
• Temperature doesn’t stay; it keeps fluctuating
• Machine emitting odd sounds
• Unusual smell from the system
• High amount of dust throughout the house
• Poor-quality air with higher chances of allergies
