Why Commercial HVAC Maintenance Matters?

The Role of Commercial HVAC

A commercial HVAC system is responsible for:

• Controlling temperature and humidity.
• Air-filtration and air-circulation.
• Controlling energy consumption and expenditure.
• Securing equipment, inventory and building structure.
• Satisfaction of code and safety requirements.

The Cost of Neglect

Failure to maintain or being late in maintenance may lead to:

• Increased energy charges through poor operation.
• Increased breakdowns and more costly.
• Reduced equipment life span.
• Uncomfort and IAQ deficiencies.
• Refunded warranties and code violations.
• Unexpected downtimes and revenue loss.

The Benefits of Preventive Maintenance

• Lower operating costs
• Fewer emergency repairs
• Longer system life
• Cosy comfort and air quality.
• Meeting of regulations and warranties.
• The tranquility of the building owners and occupants.

Professional HVAC Service and Repair

Frequently Asked Questions

How often should commercial HVAC systems be serviced?

At least once every two years (spring and fall), with a greater frequency with respect to high-use or other critical facilities.

What’s included in a commercial HVAC maintenance service?

Checking of all parts of the system in terms of inspection, cleaning, filter replacement, lubrication, test and performance checkups.

Do ductless AC systems need maintenance?

Yes. Wash filters on a 1–3-month basis and have an annual professional service.

How do I know if my system needs repair?

Observe strange sounds, fluctuating temperatures, increasing energy expenses or bad air quality.

Can I do maintenance myself?

Simple activities, such as changing filters, can be self-help, but the same activity must be left to the professional services of the maintenance team due to safety, efficiency, and warranty protection.
