What We Provide

Commercial HVAC Services We Provide

Step 1 of 5

Rooftop Unit (RTU) Repair & Emergency Service

Rooftop units provide combined heating and cooling for commercial buildings — everything your tenant needs under one roof-mounted system. When an RTU fails, business operations are affected immediately. We respond quickly to emergency calls, diagnose the problem accurately, and repair or replace components to restore operation.

Common RTU repairs include refrigerant recharge, compressor replacement, condenser coil cleaning, blower motor repair, furnace burner service, control board replacement, and electrical troubleshooting. We carry parts on our trucks and have established supplier relationships for items we don’t stock, minimizing downtime.

Key aspects of this service

  • Rapid emergency response to minimize business disruption
  • Accurate diagnosis using specialized commercial HVAC equipment
  • Repair or component replacement following Trane standards
  • Complete documentation of service work and parts installed
  • Warranty on labor and parts

Step 3 of 5

Rooftop Unit Replacement & Upgrade

If your RTU is 15+ years old, failing frequently, or becoming inefficient, replacement may be more cost-effective than continuing repairs. We evaluate your building’s cooling and heating requirements, recommend appropriately-sized replacement RTUs, and handle professional installation including electrical connections, refrigerant lines, gas lines (if applicable), and startup testing.

Modern RTUs offer better efficiency, quieter operation, and enhanced controls compared to older systems. We can also discuss alternative systems — mini-splits for zone control, split systems with indoor equipment, or hybrid approaches that provide specific benefits for your building.

Key aspects of this service

  • Evaluation of your building’s cooling and heating requirements
  • Recommendation of appropriately-sized replacement RTUs
  • Professional installation with electrical and refrigerant connections
  • Gas line connections (if applicable) and startup testing
  • Discussion of alternative systems for specific building benefits
Step 4 of 5

We can evaluate your building’s current system efficiency, identify problems or limitations, and recommend solutions ranging from maintenance improvements to system replacement.

Key aspects of this service

  • Evaluation of current system efficiency
  • Identification of problems and limitations
  • Recommendations from maintenance improvements to system replacement
