Services 1

The DXS staff is hand-selected and specially trained to provide the best possible customer service on VRF systems.  From estimating and installation to service and maintenance, we’ve got you covered.


When it comes to getting an estimate, we know what you’re thinking: Can you get it to me quickly? And can you get it to me correctly? With DXS, the answer is always yes.

We understand what’s at stake when you’re bidding on a new project to a developer or architect, or when you have the project and it’s time to put dollars and cents on paper. In either case, we’ll quickly provide you with an estimate you can count on.


We get it: with VRF, sometimes there are more questions than answers. Because of that, we’ve front-loaded our staff with engineering expertise. Our team provides full engineering support, from system layouts and energy consumption analyses to comparisons of alternate systems. We’ll work with your design team to tackle any engineering design question or challenge you have.

Project Management

Don’t expect us to hand over the equipment and head to lunch. Far from it, we’re with you from the beginning of the project to the end to ensure your VRF system meets the construction, operational and end-user goals.

Expect us to be highly visible and available from the start. In fact, we make it a point to be onsite at five critical junctures during every project:

  1. Pre-Project Training:

    Before the equipment hits the ground, we train and certify mechanical contractors or others on the installation crew who need additional training on VRF systems.

  2. QC Check During Installation:

    During refrigerant piping installation, we send a quality control technician to the site to ensure installation is done properly.  At the same time, the technician checks in with the general contractor or mechanical contractor to answer questions, provide assistance, etc.

  3. QC Check at Start-Up:

    DXS sends the same quality control technician to the project site for commissioning of the system. The technician checks the entire system and certifies it for warranty documents.

  4. Owner/Operator Verification:

    At building occupancy, DXS provides system training to the facility owners and maintenance personnel.  The comprehensive training ensures these individuals fully understand their new VRF system, covering everything from adjusting the temperature to establishing a regular maintenance schedule to troubleshooting common issues.

  5. Ongoing Training:

    For building maintenance staff.
