Humidifier Repair questions, answered by experts

NATE (North American Technician Excellence) certification is not legally required for HVAC technicians in most areas, but hiring a professional with this certification is highly recommended. NATE-certified technicians demonstrated their expertise and proficiency in different types of HVAC systems, offering assurance of quality service. It's a voluntary certification, yet it indicates a commitment to professionalism and ongoing training. Choosing a NATE-certified technician often means you're working with someone who is up-to-date on industry standards and best practices, which can lead to better service, energy efficiency, and long-term cost savings.

Professionals can enhance an A/C system’s longevity by optimizing settings and performing thorough checks on all system components.

During your HVAC preseason maintenance call, your contractor will inspect the system for any problems and make small adjustments for better efficiency. Tasks include, though are not limited to: 

  • Changing filters

  • Checking the thermostat

  • Clearing away dust and debris

  • Checking for mold

  • Inspecting electrical elements

  • Inspecting condensate lines and drain

  • Cleaning evaporator coils

  • Ensuring ignition function

While you can do some of these services yourself, hiring a professional to keep HVAC equipment running can be helpful. These experts know what to look for and may be able to spot potential issues before they become problems. Many HVAC companies offer annual maintenance plans.

Ideal humidity conditions generally range from 30% to 50%, with 45% considered optimal humidity for most homes. If your humidity levels drop below that range, you can turn your dehumidifier off. Additionally, suppose the temperature where the dehumidifier is installed falls below 60 degrees Fahrenheit. In that case, it's best to turn it off and unplug it since cooler temperatures can cause the unit's coils to freeze.

Cleaning and replacing filters and ducts reduce allergens and enhance air quality.
