Over time, the energy efficiency of your HVAC system will decline, and one of the first things you’ll notice is a spike in energy bills. The changes are gradual and may not be evident right away, but by the time they become obvious, efficiency has already dropped significantly.
Review several months’ worth of utility bills and compare the figures. A consistent increase in energy consumption is a solid indication that your HVAC system is not performing at its best.
What Is a Home Energy Audit?
A home energy audit evaluates your property’s overall energy consumption to uncover where energy is being wasted.
After an audit, you’ll have clear data on your home’s thermal envelope and mechanical performance, allowing you to take targeted measures to reduce waste and lower operational costs. A certified professional provides a detailed inspection and report to guide your next improvements.
Key Steps to Improve HVAC Efficiency
- Improve Insulation: Poor insulation in the attic, walls, or crawlspace allows conditioned air to escape and outside air to infiltrate. Improving insulation keeps temperatures stable so your furnace and air conditioner don’t have to run continuously.
- Upgrade Old Windows: Older or single-pane windows allow substantial heat transfer. Upgrading to energy-efficient windows reduces thermal loss, easing the workload on your heating and cooling equipment.
- Optimize Thermostat Habits: Over-cooling in summer or over-heating in winter wastes energy. Set your thermostat to reasonable, comfortable setpoints, and adjust temps back when away from home.
- Repair Leaky Ductwork: Leaks in attic or crawlspace ducts spill conditioned air into unconditioned spaces. An HVAC technician can conduct pressure tests and seal joints with mastic or foil tape to restore full airflow to your living areas.
- Change Air Filters Regularly: Clogged filters restrict airflow, forcing system blowers to work harder and consume more power. Replace disposable filters every 90 days (or every 30–60 days for homes with pets or allergy sufferers).
- Clean & Inspect Air Ducts: Having your air ducts cleaned every 3 to 5 years removes airflow-restricting buildup and gives technicians an opportunity to inspect the system for structural damage or hidden leaks.
- Maintain Routine HVAC Tune-Ups: Schedule annual professional maintenance—cooling in spring, heating in fall. Technicians verify refrigerant charge, clean coils, calibrate controls, and adjust electrical connections to preserve peak operational efficiency.
