RTU Unit HVAC Services (Rooftop Units)

Comprehensive service strategies

Effective RTU maintenance combines proactive measures with targeted diagnostics to maximize performance and longevity. To identify and address issues early, we prioritize preventive care and regular inspections.

Preventive Maintenance

Our preventive maintenance approach focuses on keeping RTUs in optimal condition. We develop customized maintenance plans tailored to each unit's specifications and usage patterns. Regular filter changes, coil cleaning, and lubrication of moving parts are core components of our routine service.

We inspect and adjust belts, check refrigerant levels, and clean drain lines to prevent clogs. We tighten and test electrical connections to guarantee safe operation. Our technicians also verify proper airflow and temperature differentials across the system.

By adhering to a consistent maintenance schedule, we help prevent unexpected breakdowns and extend the lifespan of equipment. This proactive strategy often leads to significant energy savings and reduced repair costs over time.

Regular inspection and diagnostics

Our comprehensive inspection process utilizes advanced diagnostic tools to assess RTU performance. We conduct thorough examinations of all major components, including compressors, condenser and evaporator coils, fans, and control systems.

We analyze refrigerant pressure and temperature readings to ensure optimal system charge. We test for refrigerant leaks and repair them promptly if detected. Airflow measurements and duct inspections help identify distribution issues that could impact efficiency.

Our technicians use infrared cameras to detect hot spots in electrical components, allowing us to address potential failures before they occur. We also evaluate control sequences and setpoints to optimize energy usage without sacrificing comfort.

Regular diagnostics enable us to track performance trends over time, facilitating data-driven decisions about repairs, retrofits, or replacements. This approach helps maximize the return on investment for RTU systems.

RTU repair and maintenance

Regular repair and maintenance are crucial for keeping rooftop units (RTUs) running efficiently. Proper upkeep prevents costly breakdowns and extends equipment's lifespan.

RTUs often utilize heat pumps to provide both heating and cooling functionalities, enhancing energy efficiency by allowing the same unit to handle different thermal needs.

Identifying common failures

RTU failures can stem from a variety of issues. We often see problems with compressors, fan motors, and electrical components. Refrigerant leaks are another frequent concern.

Signs of malfunction include:

• Unusual noises

• Inconsistent temperatures

• Higher energy bills

• Poor air quality

Regular inspections help catch these issues early. We recommend checking filters monthly and scheduling professional maintenance twice a year. This proactive approach prevents minor problems from escalating into major repairs.

Repair Solutions for Optimal Energy Efficiency

When failures occur, swift action is key. We start by diagnosing the specific issue. Common repairs include:

• Replacing worn belts and bearings

• Recharging refrigerant

• Clean coils and drain lines.

• Fixing electrical connections

For more complex issues like compressor failure, we weigh repair costs against replacement. Sometimes, retrofitting with newer, more efficient components is the best solution.

Safety is paramount during repairs. We ensure proper lockout and tagout procedures, and we use specialized equipment for working at heights. Our team stays updated on the latest HVAC technologies and repair techniques to provide top-notch service.

Options for retrofitting and upgrading

Retrofitting and upgrading RTUs offer cost-effective ways to enhance efficiency and performance. We’ll explore the benefits of these approaches and how to select the best units for upgrades.

In some cases, a more complex control system may be required for advanced control retrofits, especially in specialized scenarios like handling 100 percent outdoor air.

Benefits of Retrofitting

Retrofitting existing RTUs can yield significant energy savings. Advanced control retrofits can reduce energy costs by up to 44% compared to older systems. These upgrades often include adding variable-frequency drives, economizers, and smart controls.

Retrofits extend equipment life and improve comfort. They're less disruptive than full replacements, allowing for quicker installation and minimal downtime. Many retrofits pay for themselves through energy savings within 1–3 years.

Key benefits include:

• Lower operating costs

• Improved temperature control

• Better indoor air quality

• Maintenance needs are reduced.

Selecting RTUs for Upgrade

We focus on units over 10 years old when considering upgrades. These older systems typically waste $1,000 to $3,700 annually per unit. Size, condition, and current efficiency levels all play a role in selection.

Priority goes to units with:

• High energy consumption

• Frequent breakdowns

• Poor temperature control

Energy audits help identify prime candidates. We assess potential savings against upgrade costs. High-efficiency replacement units can cut energy use by 30–50% in many cases.

Consider:

• Current vs. new unit efficiency ratings

• Repair history and remaining lifespan

• Building's cooling and heating needs

RTU replacement processes

Replacing rooftop units (RTUs) involves careful planning and execution to ensure optimal performance and energy efficiency. The process includes a thorough assessment, proper installation, and commissioning of new equipment.

Assessment for Replacement

We start by evaluating the existing RTU's age, condition, and efficiency. Units over 10 years old or those requiring frequent repairs are prime candidates for replacement. We analyze energy consumption patterns and compare them to modern, high-efficiency models.

Building requirements are another important factor. We evaluate cooling and heating loads, airflow requirements, and any changes to space usage. This helps determine the right size and specifications for the new RTU.

We also consider the structural integrity of the roof and existing ductwork. Modifications may be necessary to accommodate new equipment. Top brands like Carrier, Trane, and Lennox offer a range of options to suit various needs and budgets.

Installing and commissioning

Once the assessment is complete, we proceed with the installation. This involves removing the old unit, preparing the roof curb, and carefully placing the new RTU. Proper handling and positioning are crucial to prevent damage and ensure a secure fit.

We connect the new unit to the existing ductwork, making modifications if needed. We install the electrical and control wiring in accordance with the manufacturer's specifications and local codes. We properly connect and charge the refrigeration lines.

Commissioning is a critical step in the replacement process. We thoroughly test all components and systems to verify proper operation. This includes checking airflow, temperature differentials, and control functions.

We calibrate thermostats and control systems to optimize performance. We program energy-efficient settings to optimize savings. Finally, we provide training to facility staff on the proper operation and maintenance of the new RTU.

Ensuring Quality and Compliance

Quality and compliance are crucial aspects of RTU repair, retrofit, and replacement services. To deliver reliable HVAC solutions, we prioritize safety standards and skilled professionals.
