Get on the Plan — $228/yr Estimates are based on industry averages from ENERGY STAR, ACCA, and Department of Energy guidance: dirty/neglected systems use approximately 15% more energy, experience 2–3× more breakdowns, and have a 30–40% shorter useful lifespan than maintained systems. Connelly's biannual maintenance plan ($228/yr) includes 10% off any repairs needed. Your actual costs will vary based on usage, climate, and equipment.
