The
days of emptying the dehumidifier and filling the humidifier are passing
quickly. There are still quite a few stand-alone models on the market, but
manufacturers have turned to designing integrated devices and controls allowing
homeowners to choose and maintain a comfort level without having to remember that when the wheel inside the big brown box in the living
room stops turning, it needs more water.
There are, however, a few steps between the manufacturer
and the homeowner in the supply chain and choosing the proper humidification or
dehumidification solution is the responsibility of the HVAC contractor.
Homeowners often come to contractors with a single complaint - discomfort.
Resolving this discomfort requires multiple considerations for the contractor
that extend beyond heating and cooling to humidity control, IAQ, etc.

Carrier’s Infinity System uses a single control to integrate
and manage all six-comfort functions: temperature, humidity, airflow,
ventilation, IAQ, and zoning.
SIX-IN-ONE CONTROL
Craig Todd, president
of Godby Heating and Air Conditioning, Indianapolis, is a residential
contractor and Carrier Factory Authorized Dealer. To help solve his customers’
humidity issues, he has been installing the Infinity System since 2003 and the
Infinity System Air Purifier since late 2006. His North American Technician
Excellence (NATE)-certified technicians commonly find themselves retrofitting
the Infinity System to fit any existing home that has a humidity issue.
“We are also specifying the Infinity System in newer
custom-built homes,” said Todd. “I personally have the Infinity System and Air
Purifier in my home, and it makes for an incredibly comfortable living
environment.”
According to Todd, the Infinity System is the first HVAC
system to use a single control to integrate and manage all six-comfort
functions: temperature, humidity, airflow, ventilation, IAQ, and zoning. The
system includes the Infinity Control, a single control that allows for
management of the entire system including levels of humidity in the home. It
also offers enhanced communication capabilities, such as advising when it’s
time for regular maintenance and filter changes.
“There’s no other system on the market with the brain
trust of the Infinity System that allows the homeowner to adjust humidity
levels and to control IAQ,” pointed out Todd. “The total system provides
optimal operation and comfort in the home.”
Todd has seen the results in his home.
“For years, I set my
home thermostat on 72°F and now I set my thermostat on 75° with the humidity
set at 52 percent,” he said. “This saves energy and money, all while
establishing the optimal indoor environment. The system provides optimal
humidity levels and unmatched indoor air quality.”
He also benefits from the Infinity System as a
contractor.
“The No. 1 benefit is proof of truly satisfied
customers,” he noted. “Additionally, the profit margins are optimal for a
dealer, and installation is made easy by the advanced technology in the
controller. You literally plug in four wires and the system is ready to go.”
Beyond residential installations, typical applications
include dental and doctor’s offices.

Rob Merholz, owner of All Temp Chicagoland Heating & Air
Conditioning in Chicago, has discovered that using Aprilaire’s Automatic
Digital Humidifier Control transfers the comfort responsibility from the
homeowner to the unit.
CONTROLLING PROFIT
Rob Merholz, owner of
All Temp Chicagoland Heating & Air Conditioning in Chicago, is a
residential and small light commercial contractor who understands the benefit
of specifying humidity control for the home and business owner. All Temp has
been in business since 1938 and has been using Aprilaire products since they
first came out with the whole-house humidifier in the 1950s.
According to Merholz,
All Temp sells
humidifiers based on the home-
owners’ needs: comfort, health,
protection, and energy savings.
“We have found that
most customers purchase a humidifier based on health and comfort,” he noted.
“Homeowners want to solve their issues with dry, scratchy throats and static
electricity, and a whole-house humidifier solves those problems.”
To help contractors like Merholz, Aprilaire has created
the Automatic Digital Humidifier Control for its line of humidifiers. The
automatic digital humidifier control features a “Humidifier On” light. This
green LED indicates when the humidifier is on and operating properly, helping
to eliminate nuisance calls. Other features include a digital display of the
home’s relative humidity (rh) percentage, and LEDs indicating when maintenance
and service are required.
All Temp has also
discovered that using this automatic control transfers the comfort
responsibility from the homeowner to the unit. Working in conjunction with an
outdoor temperature sensor to raise and lower the indoor rh percentage
automatically, the control gives the homeowner the comfort desired while
protecting the home from excessive moisture.
“The ‘set it and forget it’ feature of the automatic
digital humidifier control provides the
homeowner peace of mind,” said Merholz. “The desired level of indoor relative
humidity is a moving target, depending on the outdoor temperature. A drop in
outdoor temperature when the homeowner is away can lead to a very unhappy
customer.”
According to Merholz,
the most important aspect for every HVAC dealer is the bottom line, and his
company has grown theirs with Aprilaire humidifier installations.
“All Temp has found that homeowners are willing to pay
more for the features and benefits the new Aprilaire automatic digital
humidifier control has to offer,” he pointed out.
“Also, the decrease in installation time and the reduction
of nuisance calls means more profit on every job.”
