Why Preventative HVAC Maintenance is Important

Without proper maintenance, friction, heat, metal fatigue, and normal wear will cause reductions in the performance and efficiency of your HVAC system, and components will eventually fail, leading to breakdowns and unnecessary service calls. Routine maintenance helps to prevent this, and it can provide several other benefits, including:

  • Reduced energy usage
  • Lower utility costs
  • Fewer unnecessary repairs
  • Longer HVAC service life
  • Improved comfort
  • Better indoor air quality
  • Quieter operation

During a maintenance visit, a thorough inspection can reveal potential problems early, allowing them to be repaired before they cause a critical system failure. At Dial One Johnson Plumbing, Heating & Air Conditioning, we can keep your HVAC system in great condition, with maintenance services performed according to the manufacturer’s specifications.
