5 Maintenance Tasks You're Probably Skipping (And What They'll Cost You)
Most homeowners know they should maintain their property. Most homeowners also skip the same five tasks. Here's what those skipped tasks actually cost when they catch up with you.
1. HVAC Filter Replacement (every 60–90 days). This is the single most skipped maintenance task in America. A clogged filter forces your system to work harder, increasing energy bills by 5–15% and dramatically shortening compressor life. Cost if neglected: $2,000–$5,000 for compressor repair or full system replacement. Cost to do it: $15 and 10 minutes. There is no maintenance task with a better ROI than changing your filter on schedule.
2. Gutter Cleaning (twice per year, spring and fall). Clogged gutters cause water to pool against your foundation, seep into your basement, and rot your fascia boards. In cold climates, ice dams form and push water under your roof shingles. Cost if neglected: $1,500–$4,000 for foundation repair or water damage remediation. Cost to do it: 2 hours DIY or $150 for a professional service.
3. Water Heater Flush (annually). Sediment builds up at the bottom of your water heater tank, reducing efficiency and accelerating corrosion. Most water heaters fail between years 8 and 12 — but regular flushing can extend that to 15+ years. Cost if neglected: $3,000–$8,000 for emergency replacement (including water damage from a burst tank). Cost to do it: $150 for a professional flush, or free if you DIY with a garden hose.
4. Smoke Detector Battery Replacement (every 6 months). This isn't a cost-of-repair issue — it's a safety issue. According to the NFPA, three out of five home fire deaths occur in properties without working smoke alarms. Most failures are dead batteries, not broken detectors. Cost if neglected: potentially everything. Cost to do it: $5 and 5 minutes per detector.
5. Caulking and Weatherstrip Inspection (annually, before winter). Deteriorated caulking around windows, doors, and bathtubs lets in moisture and air. Moisture intrusion leads to mold, rot, and structural damage. Air leaks increase heating and cooling costs by 10–25%. Cost if neglected: $500–$3,000 for mold remediation; ongoing energy waste. Cost to do it: $20 in caulk and an hour of your time.
