Common Humidifier Service Questions

The cost of professional installation of a whole-house humidifier averages between $395 and $734. The materials cost between $100 and $300, so DIY installation can save some cash if you have a few skills.

Adding a whole-house humidifier can do wonders for your sinuses. The extra moisture in the air will lubricate your nasal passages, therefore improving your overall breathing. Plus, viruses thrive in low-moisture environments, so having a home with a humidifier will make you slightly less susceptible to viruses that cause respiratory illnesses. 

The life expectancy of a humidifier is around ten years on average, but this can vary depending on factors such as usage, maintenance, and the quality of the unit. To help your humidifier last as long as possible, it's important to regularly follow the manufacturer's instructions for cleaning and maintenance.

Whether you’re facing significant humidifier repair costs or it’s time to replace your humidifier altogether, it’s understandable to question whether the expense is worth it. Still, there are many benefits of whole-house humidifiers that you might miss, including improved indoor comfort, improved breathing and sleep, better hair and skin, and even increased home value. Either way, the answer is subjective, so it’s helpful to evaluate your home’s humidity without the unit running and give it a few weeks to see if you notice a difference.

Whole-house humidifiers work, but the home itself determines their efficacy. If you have a drafty house or an old home with wooden floors that leak air and moisture, the humidifier must work much harder to keep moisture levels constant. Because of this, we recommend doing an air test of your home to determine the best type of humidifier and any work that needs to be done to install it.
