Matrix’s skilled service technicians and vehicles are equipped with the latest tools, diagnostic equipment, supplies and inventory to get your HVAC system up and running quickly. We also maintain equipment that can be installed temporarily while we effect repairs on your existing system if necessary.

When performing repairs or regular maintenance on your HVAC system, if a Matrix technician finds that an equipment repair or replacement is imminent, we will provide a full evaluation and estimate so that you can schedule and budget accordingly. Our detailed evaluation will be provided at no cost to you and is usually delivered within one business day.

To prevent costly shutdowns or disruptions to your HVAC system, let Matrix develop a customized HVAC maintenance program suited to your specific cost and performance requirements.

Contact Matrix HG for a detailed evaluation of your current system. Although this is a time-intensive and detailed service, we do it at no cost to you, whether you are a new or existing Matrix customer. For a description of what’s included in our evaluation, as well as additional information about proactively maintaining your HVAC system, see Predictive & Preventive Maintenance. Call us at 925-459-9200 to request your system evaluation.


When it comes to critical infrastructure, no one likes surprises. The best way to prevent surprises is to have ongoing preventative maintenance to keep your HVAC systems performing optimally for the life of the equipment and to replace outdated systems or components before they fail.

HVAC System Evaluation

When performing regular maintenance, a Matrix technician may detect that a needed equipment repair or replacement is imminent. If this occurs, we will provide a full evaluation and estimate to help you schedule and budget for needed repairs. As in everything we do, we go above and beyond what is minimally-required in delivering this service. Beyond just letting you know about anticipated maintenance, Matrix HG provides a thorough evaluation that will also tell you:

  • Which systems or components are likely to fail or need maintenance
  • A full cost estimate
  • When updating the system and/or component parts might provide cost-savings from factors like:
    • improved performance
    • eliminating repeated maintenance on older systems
    • ongoing cost-savings through energy-usage and/or rebates
  • When we believe that a repair of the existing system will be more cost-effective than a replacement, upgrade, or modernization
  • As early as possible, when we notice that a system may need extensive investment for replacement or repair

Matrix’s HVAC system evaluation helps you plan for needed improvements well in advance of an anticipated system failure.

We provide this detailed report to you within a day of our site visit – at no cost to you! We go the extra mile to help our customers to manage costs, optimize HVAC system performance, schedule maintenance, avoid system failures, and mobilize our teams quickly in response to emergencies. Because of this, we are proud to be part of our customers’ continued success.

If you’re not already a Matrix HG customer, call us today and see what a difference we can make – in the performance of your HVAC system and in your bottom line. Call us at 925-459-9200.
