Unless you're very skilled with HVAC, plumbing, and electrical work, it's best to hire a professional. Improper installation can damage your HVAC system, increase energy bills, and reduce equipment lifespan. A pro will ensure everything is installed correctly and safely.
It depends on your maintenance preferences and budget. Drum humidifiers cost less upfront but require more frequent maintenance to prevent mold growth. Flow-through humidifiers are a bit more expensive but need less upkeep because they have fewer parts that can harbor mold. Consider how much maintenance you're willing to do when choosing between the two.
Repairing a whole-house humidifier costs an average of $230, with prices ranging up to $500 depending on the type of unit, extent of the repair, and labor fees in your area. Units integrated into your ductwork or servicing larger homes may incur higher repair costs. Regular maintenance can help prevent expensive repairs and extend the life of your humidifier, saving you money in the long run.
If your home's humidity level drops below 30%, a whole-house humidifier can help. Dry air can lead to discomfort and health issues. Energy Star recommends keeping indoor humidity between 30% and 50%. In colder regions, aim for 30% to 40% in winter to prevent window condensation. If your home has too much humidity, you may need a whole-house dehumidifier.
Whole-house humidifiers typically last 10 to 15 years. If your unit is nearing this age or isn't working well, it might be time to replace it. Upgrading can improve efficiency and save on energy costs. Consult a professional to assess your unit.
A whole-house humidifier is installed directly into your HVAC system, usually near the furnace or air handler. It connects to your ductwork and plumbing. Because installation involves integrating with existing systems, it's best to hire a professional to ensure everything works safely and efficiently.
