Why Invest in HVAC Maintenance?
Think of HVAC maintenance like an oil change for your car—it’s essential. In fact, routine maintenance can improve system efficiency by up to 20%, reduce energy bills, and extend your system’s lifespan by several years. Neglected systems lose around 5% efficiency annually and are far more likely to experience sudden, expensive breakdowns.
Here’s what regular HVAC tune-ups can help you avoid:
- Higher utility bills from overworked systems
- Shortened equipment lifespan
- Poor indoor air quality
- Emergency repair costs in peak summer or winter
- Voided manufacturer warranties
