Proper humidity levels at home provide comfort and health benefits ranging from alleviated allergies to reduced flu virus transmission. As the leading name in whole-home humidification since 1954, Aprilaire offers a variety of humidifier models to suit any space. But regardless of the type, periodic maintenance is required for peak operation. From replacing tired parts to cleaning mineral deposits, a little DIY care goes a long way.
This guide covers the critical Aprilaire humidifier components that may need replacement, where to get genuine parts, cost-saving tips, troubleshooting issues, and frequently asked questions. Let’s keep your system running at its best!
Choosing the Right Aprilaire Humidifier for Your Home
Aprilaire makes several humidifier models using different technologies to disperse moisture through your home:
- Bypass humidifiers are the most affordable option. Using your existing HVAC blower motor, they pass air through a wet wick or drip pad to add humidity. Simple but limited flexibility.
- Fan powered humidifiers contain their own internal fan to circulate air through a moisture-laden rotor or evaporation pad. Offers more precise humidity control.
- Steam humidifiers boil water and inject the vapor into ductwork for distribution. Most effective for humidity but higher energy use and maintenance.
- Flow-through humidifiers mount on supply plenums to humidify air before it enters living spaces.
- Portable humidifiers release moisture into a single room rather than the whole home.
Factors like climate, home size, number of floors, and efficiency rating help determine the ideal Aprilaire model for your needs. Consult HVAC pros to pick the right system – this also dictates the replacement parts you’ll later need.
Critical Aprilaire Parts to Replace
While Aprilaire systems are built to last, several components require periodic replacement as they wear out:
- Water Panels: The wicking media inside bypass humidifiers that absorbs and evaporates water. Signs it’s time to replace them include restricted airflow, leaks, and reduced moisture output.
- Humidistats: Detects indoor humidity and signals the system to turn on/off accordingly. Replace faulty humidistats that cause indoor RH to fluctuate widely. New digital models provide improved accuracy.
- Solenoid Valves: Opens and closes to regulate water flow into the humidifier. Dripping or unwanted water flow indicates it’s time for a new valve.
- Drain Pans: Collects excess condensation and drains it out of the system. Replace cracked or warped pans prone to leaking and water damage.
- Filters: Traps particles before air enters the humidifier. Replace 2-4 times per year for unrestricted airflow.
- Fans & Motors: Circulate air through evaporative media. Replace worn out motors making noise or failing to turn.
- Steam Canisters: Found in steam models, they convert water to vapor. Replace mineral-coated canisters for optimal steam output.
Don’t wait for full failure – replace parts at the first signs of wear to avoid bigger problems. Refer to your owner’s manual for detailed replacement guidance.
Purchase Genuine Aprilaire Parts for Reliability
While cheaper generic parts are tempting, opt for OEM Aprilaire components for the best fit, performance and longevity. Beware lower-quality knock-offs with inferior materials. Signs of genuine Aprilaire parts include:
- Official Aprilaire packaging and branding
- Made from top-grade materials
- Perfectly contoured for seamless installation
- Lasts for years of flawless operation
Purchase replacement parts directly from Aprilaire or authorized dealers. Reputable HVAC companies and Amazon sellers also carry genuine components – just double check their credentials.
DIY Maintenance and Easy Repairs
With basic mechanical skills, many Aprilaire repairs can be DIY to save on labor costs:
- Swapping out air filters
- Drain line flushes to clear obstructions
- Cleaning water panels and humidifier interior
- Replacing evap pads, steam canisters, and drain pans
- Troubleshooting issues using error codes and manuals
Know your limits though – leave complex repairs like motor replacement and major disassembly to experienced pros.
When parts start to fail, weigh the costs of replacement vs. full unit replacement if nearing the 10-15 year lifespan. Repairs often make sense unless multiple components are degraded.
Cost-Saving Tips for Aprilaire Parts
While critical to performance, replacement humidifier parts impact your wallet. Use these tips to save:
- Purchase bundled part kits containing common components
- Join the Aprilaire rewards program for seasonal coupons and discounts
- Stock up during holiday sales on parts you’ll eventually need
- Only replace faulty parts instead of fully rebuilding the unit
- DIY easy repairs instead of paying for professional installation
Proactive maintenance prevents much pricier premature unit replacement when parts fail.
Troubleshooting Common Aprilaire Humidifier Problems
Even well-maintained systems encounter periodic problems. Use these troubleshooting tips:
- Clean obstructed drain lines causing backups
- Replace worn out water panels
- Faulty solenoid valves require replacement
Low Humidity Output:
- Clean or replace dirty air filters restricting airflow
- Replace mineral-coated evaporator pads and steam canisters
- Make sure float moves freely; clean away mineral deposits
- Add water softener to reduce mineral content leaving dust
- Replace old water panel and clean humidifier interior
- How long per day should my Aprilaire run? 12-16 hours maintains proper humidity.
- What humidity level is recommended? Ideal range is 40-50% relative indoor humidity.
- What causes weird noises? Buzzing, cracking, or whining sounds indicate a worn motor, solenoid valve, or evaporator pad needing replacement.
Don’t hesitate to contact Aprilaire support for troubleshooting advice specific to your model. Proper maintenance keeps your system running optimally for years beyond short-lived generic parts. Invest in quality OEM components and DIY repair skills for lasting performance.
