The HVAC system is one of the most important inventions of modern times. Your HVAC system works round the year to maintain a comfortable indoor temperature. In addition to heating and cooling your home, your system plays a vital role in maintaining the indoor air quality.
Like all other equipment, your HVAC system requires periodic maintenance. Regular maintenance minimizes problems and maximizes efficiency. A well-maintained system is more reliable than a poorly maintained one. That said, even a well-maintained system can develop problems and stop working.
