What Is HVAC Retrofitting?

As your HVAC system ages, you are bound to notice it becoming less energy efficient. In fact, older systems simply don’t have all of the efficiency improvements that characterize modern systems. Older equipment is more expensive to operate and is often prone to needing more frequent repairs than a newer system.

So if you’re noticing energy bills beginning to climb, you may be considering replacing your system with brand new equipment. However, depending on your situation, retrofitting your HVAC system might be a better option. You can extend the effective life of your HVAC for several years and lower your energy bills—all for only a fraction of the cost of a full-fledged replacement.

An HVAC retrofit optimizes your existing heating and cooling infrastructure by replacing outdated components with the latest in high-efficiency technology. While we make upgrades, you can keep your facility up and running with minimal HVAC equipment downtime.

We frequently replace system components as part of a holistic retrofit solution. This includes:

  • Replacing old screw compressors with new high-efficiency screw compressors for chillers
  • Adding condenser fans with high-pressure controls and variable frequency drives for air-cooled chillers
  • Installing air-side economizers for HVAC units
  • Adding supply fan speed controls
  • Implementing demand-controlled ventilation
  • Adjusting cooling capacity controls
  • Selecting and installing holistic retrofit kits

Commercial HVAC Retrofitting

Retrofitting your air conditioning or heating system could save you thousands of dollars in energy costs while minimizing replacement issues.

Benefits Of An HVAC Retrofit

React Mechanical works to save you money by improving your existing HVAC system so that it’s more efficient, increases comfort levels, and maximizes your energy savings. With the latest components, we can extend the life span of your system to get the most out of your HVAC investment.

Retrofits offer an ideal option for commercial building owners who want to save money on energy bills but don’t necessarily want to invest in a brand new heating or cooling system.

Other benefits of an HVAC retrofit include:

  • Cost-effective improvements: When comparing the cost of a commercial HVAC system retrofit versus a full replacement, there’s a dramatic difference in up-front costs. There is a substantial benefit to putting off the long-term investment in a full-scale replacement. Retrofitting can offer cost savings that buy you time and peace of mind.
  • Increased energy efficiency and lower energy bills: On average, small offices and retail establishments reduce energy consumption by 35% with an energy retrofit. In cold weather climates, this number can even rise to 40%.
  • Extended life span for your current system: By retrofitting, you’ll be able to extend your system’s life expectancy by several years while also spending less than you would for an entire replacement.
  • Improved indoor air quality: With an optimized HVAC system, your employees will enjoy a safe and comfortable environment. Temperatures throughout the building will stay consistent and controlled, and improved air filtration will ensure no particulate matter gets into the working environment.
  • Optimized peak load performance: With new technology comes elevated performance and dependability to decrease maintenance and service costs.
  • A quick return on investment: You’ll save on both energy and service costs when you choose to retrofit instead of investing in the installation of a new HVAC system.
  • Rebates and incentives: By retrofitting, you could be eligible for energy-efficiency rebates and potential tax incentives.
  • Minimal chance of a critical system failure: An unexpected HVAC system breakdown can play havoc with departmental budgets. With planned heating and cooling upgrades and maintenance, costs become controlled and predictable, which can save money and help relieve stress and anxiety.

Not every HVAC system is suitable for retrofitting, but many heating and air conditioning systems qualify for upgrades that maximize your investment. Your unit may be improved by retrofit if any of the following are true:

  1. Your system is older but still in good working condition.
  2. Your HVAC system has been regularly and professionally maintained.
  3. You have an extensive system. Larger systems are typically better candidates than smaller ones, as the cost differences between retrofit versus replacement increase.
  4. You’ve noticed that your monthly energy bills have been increasing.
  5. You run your system regularly throughout the day.
  6. You’re planning on keeping your existing system for 18 months or longer.
