HVAC Efficiency and Energy Use: Where the Waste Hides

The biggest sources of wasted energy in heating and cooling and the fixes that tend to pay off first.

2 minute read

Key takeaways

  • Leaky ducts and thin insulation waste a lot.
  • A properly sized system runs better than an oversized one.
  • Thermostat habits and filters matter.
  • Check current utility and federal incentives before you buy.

Ducts and insulation

Ducts that leak in attics and crawl spaces lose a large share of conditioned air. Sealing and insulating them is often the best first step.

Adding attic insulation can also reduce the load.

Equipment sizing and condition

A system that is the wrong size or dirty uses more energy than it should. Regular tune-ups and correct sizing keep it near its rating.

A new system is not always the first move.

Controls and habits

A good thermostat and steady schedule avoid waste. Very large setbacks can make some systems work harder on recovery.

Keep vents unblocked and filters clean.

Incentives

Utilities and the federal government sometimes offer incentives for efficient equipment. Programs change, so check current rules before you buy.
