Understanding What’s Included in a Commercial HVAC Maintenance Plan

Regular HVAC maintenance isn’t just for homes—it's a critical part of running a smooth, efficient, and comfortable commercial space. Whether you manage an office building, restaurant, retail space, or industrial facility, a well-maintained HVAC system reduces energy costs, minimizes downtime, and extends the life of your equipment.

At Tarrant Mechanical, we offer commercial HVAC maintenance that’s tailored to your property and schedule. But what exactly is included in these visits?

Let’s break it down.

1. System Inspection and Testing

Our technicians begin with a comprehensive inspection of your HVAC system, including:

• Rooftop units or split systems
• Air handlers and ductwork
• Thermostats and control systems
• Condensers and evaporators

We check for signs of wear, unusual noises, safety hazards, or anything that could lead to future failure. Testing ensures your system is operating at its intended performance level.

2. Filter Replacement and Airflow Check

Clean filters are essential for system efficiency and indoor air quality. We:

• Replace dirty filters
• Inspect return and supply vents
• Verify airflow through each zone

Clogged filters or blocked vents make your system work harder and increase your energy bills—something we help you avoid.

3. Coil Cleaning

Dust and debris build up on condenser and evaporator coils, especially in high-traffic commercial spaces. We clean both to:

• Improve heat transfer
• Boost cooling efficiency
• Prevent system overheating

This simple step can make a huge difference in energy usage and unit performance.

4. Refrigerant Level Check

Low refrigerant causes your system to work inefficiently or stop cooling entirely. We:

• Check refrigerant pressure
• Inspect for leaks
• Recharge if needed (with your approval)

Refrigerant issues are one of the most common causes of commercial AC problems, and early detection saves you from mid-season emergencies.

5. Electrical Component Inspection

Loose connections or worn electrical parts are fire hazards and can cause unexpected shutdowns. We inspect and tighten:

• Wiring
• Relays and contactors
• Capacitors and fuses
• Motors and fans

If anything looks unsafe or underperforming, we’ll give you a clear, honest recommendation.

6. Thermostat and Controls Calibration

Your HVAC system is only as effective as its controls. We check:

• Calibration accuracy
• Programmable schedules
• Communication between zones
• Smart thermostat functionality

Ensuring the system responds properly to temperature settings saves energy and improves comfort throughout your building.

7. Drain Line and Pan Clearing

Commercial systems often experience:

• Clogged drain lines
• Overflowing condensate pans
• Mold or mildew growth

We flush and sanitize these components to prevent water damage or health risks from poor drainage.

8. System Efficiency Report

At the end of every maintenance visit, we provide a detailed breakdown of:

• What was checked
• What was cleaned or replaced
• Any problem areas found
• Suggested repairs or optimizations

You’ll always know the health of your system and be able to plan repairs before they become expensive emergencies.
