Customers say: Quick response

"Jacob and Cody have been amazing to work with. We originally hired them to repair our stairs and have since contracted with them to install our kitchen tile floor, install electric in our kitchen island and to repair some of our drywall. Their team is very professional, their estimates are accurate and they do quality work. We plan to hire them again when we remodel our bathrooms."

Humidifier Repair FAQs, answered by experts

While you’re busy swapping out that old compressor, now is a great time to have your furnace cleaned and serviced , especially if your home is older and your heating system is as old as your AC unit. Likewise, it’s a good idea to clean your air ducts to ensure air flows properly through the house.

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. 

NATE-certified technicians may charge slightly higher service fees compared to non-certified technicians. This is because NATE certification signifies a higher level of expertise and professionalism, often leading to more efficient and effective HVAC repairs and installations. While the upfront cost may be marginally higher, NATE-certified technicians can potentially save you money in the long run by reducing energy consumption, preventing frequent breakdowns, and extending the life span of your HVAC system. When looking for a local HVAC company to hire, it never hurts to ask about NATE certifications.

It improves air quality, prevents dry skin, protects wood furniture, and enhances overall comfort.

For certain repairs, a plumber may be able to help fix a humidifier, but HVAC technicians are typically the go-to professionals. The most common humidifier repairs that plumbers handle are humidifier water shutoffs, solenoid valve maintenance, and evaporator pad replacement.
