Evaluate Indoor Air Quality

We test your home's humidity levels and assess your HVAC system to determine the best humidifier solution for your space and comfort needs.

Install & Connect

We install your whole-home humidifier directly into your HVAC system and connect it to your water supply. Everything is done professionally and cleanly — no mess, no hassle.

Test & Calibrate

Once installed, we calibrate the humidistat to your ideal humidity level and test the system to confirm proper operation. We'll walk you through how to use and maintain your new humidifier.

ype of Humidifier

Bypass humidifiers use your HVAC blower to push air through a water panel, making them a cost-effective option. Fan-powered humidifiers have their own fan and can produce more moisture output, which is ideal for larger homes. The type you choose affects both performance and price.

Home Size

Larger homes require humidifiers with higher moisture output capacity. The square footage of your home and the number of levels will determine the size and type of humidifier needed for effective whole-home coverage.

Existing HVAC Integration

Whole-home humidifiers connect directly to your existing HVAC ductwork and water supply. If your system requires modifications or additional plumbing work for the water line, this may add to the installation cost.

Water Supply Connection

Humidifiers need a dedicated water supply line. If one is already nearby, installation is straightforward. If new plumbing is required to route water to your HVAC system, this will add to the project scope and cost. Henson handles both HVAC and plumbing, so we can manage the entire installation in-house.
