Choosing the right system for your home
We carry Aprilaire whole-home humidifiers and will help you find the right fit during a no-pressure consultation. The main options are:
Bypass humidifiers are the most common and affordable choice, connecting directly to your furnace and using warm airflow to distribute moisture. Best for small to mid-size homes with a gas furnace.
Fan-powered humidifiers have a built-in blower for stronger, more consistent output — a better fit for larger homes.
Steam humidifiers generate humidity independently of your heating system, making them the most effective option and the right call for homes with a heat pump.
Have a heat pump? Bypass units don’t perform well on heat pump systems — lower discharge temperatures reduce evaporation. Fan-powered works, but steam is the recommended choice. We’ll assess your system and advise accordingly.

Humidifier FAQs
Does my home need a humidifier? The best way to determine if you need help with humidity levels in your home is to buy a small gauge at the hardware store to measure them. If your humidity is usually below 30%, it is too low, and you need a humidifier. If it is above 50% regularly and you see moisture on your windows, then it’s too high, and you need a dehumidifier.
Can I use both a humidifier and a dehumidifier together? Yes. Because the weather has seasons and those seasons bring unique needs for the home, you can use both a humidifier and a dehumidifier in your home. Just make sure you switch between the two based on the humidity levels in your home month to month. You should not need to run both at the same time, as they will counteract each other. Strive to keep the home’s humidity between 30% and 50%.
How many hours a day should the humidifier run? If you have a whole-house humidifier, it will run when the HVAC system runs. If you have a separate unit, consider running it whenever the humidity levels in the home or room demand. We recommend whole-house humidifiers so that you can ensure comfort at all times and have less need to turn on and off the system.
Will a humidifier make my home damp? If humidifiers are used too often, it can lead to high humidity levels in the home, creating overall feelings of dampness. If a humidifier is used properly, it will not cause this problem. Always measure humidity levels when using a humidifier to ensure you aren’t letting them get too high.
Do humidifiers kill viruses? Technically, humidifiers do not kill viruses. However, higher humidity levels make it harder for some viruses to stay in the air, making it less likely that you will get sick. When used alongside air purifiers, humidifiers can improve the overall indoor air quality inside your home.
Do you offer free estimates? Yes. We provide transparent, upfront estimates before any work begins so you know exactly what to expect — no hidden fees.
How quickly can you install a whole-home humidifier? In most cases we can complete installation the same day. Most jobs take 2–4 hours from start to finish.
What brands do you carry? We install Aprilaire whole-home humidifiers, one of the most trusted names in indoor air quality. During your consultation we’ll recommend the right model for your home and budget.
Will a whole-home humidifier work with my existing HVAC system? In most cases, yes. Our technicians will assess your system during the consultation and recommend the right unit. Homes with heat pumps have specific requirements — we’ll make sure you get a system that’s properly matched.
Do you service humidifiers you didn’t install? Yes. Whether you need a repair, maintenance, or a replacement water panel on an existing unit, we’re happy to help regardless of who originally installed it.
Do you offer maintenance plans? We do. A whole-home humidifier needs an annual water panel or canister replacement to perform properly. Our maintenance plans take care of that automatically so you don’t have to think about it.
Are your technicians licensed and certified? Yes. Our technicians are NATE-certified with an average of 12+ years of experience in HVAC and indoor air quality systems.
