Commercial Rooftop Unit Service in Omaha, Nebraska

Our Commercial RTU Installation Process

Our installation process begins with a thorough evaluation of your building's heating and cooling requirements. We assess factors that directly impact system performance:

• Building square footage and layout

  Ensuring the RTU is properly sized for the space it serves

• Occupancy levels and usage patterns

  Restaurants, retail stores, and offices have very different demands

• Existing ductwork and curb conditions

  Evaluating whether current infrastructure supports the new unit or requires modification

• Ventilation requirements

  Meeting commercial building codes and fresh air standards for your specific application

• Energy efficiency goals

  Recommending units with appropriate SEER and EER ratings to manage operating costs

We work with Armstrong and Bosch commercial equipment, giving our clients access to reliable, energy-efficient rooftop units backed by strong manufacturer warranties. Our Armstrong ProTeam status means we meet the highest standards for installation quality and technical proficiency — a distinction that directly benefits your business through better system performance and fewer warranty issues.

Replacement and Retrofit Projects

When an existing rooftop unit has reached the end of its useful life, our team handles the complete replacement process. We manage crane coordination, curb adapter modifications, electrical and gas connections, ductwork transitions, and thermostat or building automation integration. Our goal is to minimize disruption to your business operations, and we regularly schedule changeouts during off-hours or weekends to keep your doors open and your employees comfortable.

For buildings with older, less efficient RTUs, a replacement can deliver significant energy savings. Modern commercial rooftop units offer improved compressor technology, variable-speed blower motors, and advanced economizer controls that reduce utility costs while maintaining consistent comfort.

What Our Commercial RTU Maintenance Includes

A thorough commercial RTU maintenance visit from our team covers every critical component:

• Filter inspection and replacement

  Dirty filters restrict airflow, reduce efficiency, and degrade indoor air quality for your employees and customers

• Condenser and evaporator coil cleaning

  Removing dirt and debris that insulates the coils and forces the system to work harder

• Belt inspection and adjustment

  Checking belt tension and wear to prevent unexpected blower failures

• Electrical connection inspection

  Tightening connections and checking amp draws to catch potential issues before they cause failures

• Refrigerant level verification

  Confirming proper charge to maintain cooling capacity and efficiency

• Economizer calibration

  Verifying damper operation and sensor accuracy to maximize free cooling hours

• Gas heat section inspection

  Checking ignitors, flame sensors, heat exchangers, and gas pressure to ensure safe, reliable heating

• Thermostat and controls check

  Verifying proper communication and operation between the building controls and the RTU

• Condensate drain clearing

  Preventing water damage and humidity issues caused by blocked drains

• Overall system performance evaluation

  Measuring supply and return air temperatures, static pressure, and airflow to confirm the system is operating within design parameters

The Business Case for Preventive Maintenance

Commercial buildings in the Omaha Metro area put their rooftop units through demanding conditions. Nebraska summers push cooling systems hard, and our winters challenge even well-maintained heating equipment. Regular professional maintenance helps your business in several tangible ways:

Over 20 Years of HVAC Experience

With more than two decades in the HVAC industry, we have built the technical knowledge and field experience that commercial clients depend on. We have worked on rooftop units across every major commercial application, and that breadth of experience translates into faster, more accurate diagnoses and better long-term solutions for your building.

Armstrong ProTeam Dealer

Our Armstrong ProTeam designation reflects the highest level of dealer certification with Armstrong Air. This is not a participation award — it is earned through demonstrated excellence in installation quality, technical proficiency, and customer satisfaction. For our commercial clients, this means access to premium equipment and the factory-trained expertise to install and service it properly.

Larson & Johnstone Distributor Partner

Our partnership with Larson & Johnstone gives us direct access to a vast inventory of commercial HVAC equipment and replacement parts. When your rooftop unit needs a component, our distributor relationship helps us source it quickly, reducing your downtime and getting your system back to full operation faster.

24-Hour Emergency Response

Commercial HVAC emergencies happen on their own schedule. Our 24-hour emergency service means your business is never left waiting until Monday morning for a critical repair. We respond to emergency calls from commercial clients throughout the Omaha Metro area, including Omaha, Gretna, Elkhorn, Bellevue, Papillion, and Bennington.

Honest, Straightforward Communication

We believe in giving our commercial clients clear, honest assessments. If a repair makes sense, we will tell you. If replacement is the better long-term investment, we will explain why and provide the information you need to make a sound business decision. Our goal is to be the HVAC partner you trust for the long term, not just the next service call.

Businesses throughout the Omaha Metro area rely on Rosewood Heating & Air Conditioning for dependable commercial HVAC service. Our commitment to responsive communication, accurate diagnostics, and quality workmanship has earned us lasting relationships with commercial clients across a wide range of industries. We treat every business — whether a single-unit retail shop or a multi-unit commercial facility — with the same level of professionalism and attention that we would want for our own operations.

Our approach to commercial service is simple: show up when we say we will, diagnose the problem accurately, explain your options clearly, and do the work right the first time. It is not a complicated formula, but after more than 20 years in this industry, we have found that consistently executing these fundamentals is what earns and keeps the trust of our commercial clients.

Your commercial HVAC system is not just a piece of equipment on the roof — it is a critical component of your business operations. When that rooftop unit is running properly, your employees are productive, your customers are comfortable, and your products and inventory are protected. When it is not, everything suffers. That is why choosing the right commercial HVAC partner matters.

Rosewood Heating & Air Conditioning has spent more than 20 years building the expertise, the relationships, and the reputation that Omaha Metro businesses depend on. As an Armstrong ProTeam dealer and Larson & Johnstone distributor partner, we bring factory-level knowledge and direct access to quality commercial equipment to every project. Our technicians are not just trained — they are experienced. They have worked on commercial rooftop units in every type of building, in every season, and under every kind of condition that Nebraska weather can produce.

We believe that great commercial HVAC service starts with understanding your business. A restaurant has different needs than an office building. A warehouse requires a different approach than a medical facility. When you work with Rosewood, we take the time to understand your operation, your building, and your priorities. Then we recommend solutions that make sense for your specific situation — not a one-size-fits-all approach that ignores the realities of your business.

Our 24-hour emergency service is not just a marketing promise — it is a commitment that we back up every day and every night. When your rooftop unit fails at midnight on a Saturday, we answer the phone. When your heating goes out during a Nebraska cold snap, we respond. That level of reliability is what businesses expect, and it is what we deliver.

Whether you are a property manager overseeing multiple buildings, a business owner focused on keeping your team comfortable, or a facilities director responsible for maintaining building systems, Rosewood Heating & Air Conditioning is ready to be your commercial HVAC partner. We handle everything from routine maintenance and minor repairs to complete rooftop unit replacements, and we do it all with the professionalism and transparency that our commercial clients have come to expect.
