You can achieve greater reliability and improve your bottom line by reducing your energy use. Let’s work together to maximize your building’s efficiency. You’ll notice the savings on the bottom line.

Commercial AC Maintenance for Chillers and Rooftop Units

Commercial heating and air conditioning systems rely on over 100 components working synchronously. As individual parts wear out, the unit’s efficiency decreases. We maintain heating and cooling systems down to the smallest nuts and bolts, because each one matters.

Duncan Heating & Air Conditioning, Inc. & Plumbing uses a combination of preventive and predictive maintenance. We follow manufacturers’ recommendations, but we tailor them to your HVAC system. This reduces downtime by 40 percent, cuts maintenance costs by 30 percent and prevents 75 percent of breakdowns.

These benefits deliver a 10-fold return on investment according to the Federal Energy Management Program. We focus on maintenance services that offer maximum financial advantages to businesses in Lubbock, TX.

  • Adjusting the refrigerant in your rooftop AC equipment lowers your energy bills by 5 to 11 percent.
  • Balancing the airflow in your commercial cooling system can cut your energy bills by 10 percent.
  • Economizers allow rooftop AC units to cool your building with outside air. Failing economizers drive your energy bills up by 15 percent or more.
  • Centrifugal chillers benefit from descaling treatments. Microbes and mineral deposits slow the heat exchange rate by 15 percent.
  • Cleaning clogged condenser valves improve the heat transfer rate in centrifugal chillers.
  • During scheduled downtime, we test for air leaks that decrease the chiller’s cooling capacity. A 1-psi leak decreases the system’s efficiency by 5 percent.
  • Lubricating oils that infiltrate refrigerants impair the system’s performance. For every 1 percent of oil in the refrigerant, your chiller loses 2 percent of its efficiency.
