Humidifier repair, maintenance and startup.

A disc assembly sends a little bit of moisture into the air. Whatever your humidifier needs are your PDM humidifier specialist can help. Best yellow super trucks carries a variety of humidifier parts for a quick fix. You'll know a price before we begin and have two year workmanship guarantee. Call a Best humidifier expert for help.

Humidifier needs annual check-up.

Keeping your home humidifier in top shape will help you stay warmer and more comfortable all winter long. Ideally your humidifier should be cleaned (and dried) at the start (or end) of the heating season.

You don't want to allow film and scale to develop on humidifier components. Although not all humidifiers are the same, here's Best's home humidifier maintenance program.

  1. Drain water. Sometimes bacteria can grow in the standing water. Replace the water when needed.
  2. Clean system. A chemical and antibacterial solution may be needed to prevent and eliminate scale and rust build up and then thoroughly rinse out the system.
  3. Do you have very hard water? You'll find that filters need to be replaced more often and that more cleaning (draining tank too) is required. If needed we’ll add or replace a demineralization cartridge or filter to help reduce scale build up.
  4. Disc assembly.  A humidifier disc assembly collects a thin layer of water and then air is passed through picking up humidity and sending a little bit of comfort into every room of your home. Your disc will be removed and cleaned. A Best tech will make sure the disc is free of obstructions.
  5. Float assembly.  The float often gets stuck when not operating during the summer. The valve must move freely to maintain proper water level. Inspect and clean if necessary.
  6. Check water level and distribution system. You may have potential problems like loose hose or piping, saddle valve, drain cap, etc. We make sure they are securely fastened. If they leaked it could cause a messy problem.
  7. Check motor and fan operation - heart of a humidifier.
  8. Humidifier water panel (filter). Humidifier filters can become completely plugged with hard water scale allowing little or no water to reach your unit. You should replace water panels when needed otherwise your comfort will suffer and you'll have added repairs. We'll inspect and advise you.
  9. Check for proper air flow and ensure all connections are tight. Open damper door to Open position to allow hot air to flow to humidifier.

Test humidistat operation, adjust to comfortable setting.

Your humidifier is now clean and ready to go.

Our fall or spring maintenance and humidifier startup makes sure your humidifier is operational for another season of comfortable living. Best has been installing, maintaining and repairing whole home humidifiers for over 50 years. We have the parts and know-how to keep you comfortable.

Save yourself from the damaging effects of over dry air with a new automatic humidifier.

It's pretty hard to ignore the health and energy saving benefits of a whole home humidifier.

  1. Normal heated home humidity can be 13 - 16%. To be comfortable the recommended relative humidity level should be about 35%. A humidifier automatically adds the right amount of moisture.
  2. You can also set indoor temperatures lower by two degrees or so and still feel as warm as you did. Every degree lower you set thermostat saves about three percent on utilities.
  3. Do you suffer from uncomfortable dry throat, nose, itchy eyes, coughs, winter-time asthma? A humidifier is for you
  4. Looking to relieve upper respiratory infection or congestion? Adding moisture (whole home humidifier) to dry winter time air is a common way to feel better
  5. Humidifier helps keep your mucus membranes moist - helpful for asthma sufferers
  6. Humidifier reduces static electricity which causes problems with electronic equipment and static shocking
