What a heavy FPL bill has to do with air quality

An Ormond Beach summer bill climbs for mechanical reasons more often than for behavioral ones, and two of the mechanical reasons are air quality problems in disguise. A filter that has loaded up with March oak pollen and never been changed restricts airflow, so the blower works harder and the coil freezes on the hottest days. A coil furred with the mold film that grows on any wet surface at a 73-degree dew point transfers heat poorly, so the compressor runs longer to do the same job. Both show up on the bill before anyone notices the air. The Lennox Healthy Climate line is the set of products that keeps the filter and the coil doing their jobs, and the humidity and fresh-air pieces that keep the house from growing the problem in the first place.

Retrofit into an existing system, or designed into a new one

Most of the Healthy Climate equipment we install in Ormond Beach goes onto a system that is already there. The media filter cabinet replaces a one-inch filter slot at the air handler or at the return grille. The UV lamp mounts inside the air handler above the coil. A ducted dehumidifier sits beside the air handler and ties into the return and supply. None of that requires a new system, and on a 1990s air handler in Breakaway Trails or a 2000s one in Ormond Lakes it can all be fitted in a day.

On a new Lennox system, in a Plantation Bay build or a full replacement in Tomoka Oaks, the same pieces are designed in from the start: the air handler is chosen with the filter cabinet in mind, the purification system is wired to the thermostat so it runs when the system runs, and the fresh-air ventilator is controlled by the same thermostat. The integrated version costs little more than the retrofit and works as one system rather than four add-ons. Ask which Healthy Climate components Cook’s currently stocks for retrofit versus new-system installs. [[CONFIRM WITH JERRY]]

The ductwork decides what fits

A return built in 1978 for a fiberglass pad will not feed a deep media filter without being enlarged, and a filter cabinet that does not fit the attic space in a Tymber Creek split-level goes at the grille instead. Those are the two ductwork realities we meet most in this town, and they decide the layout before the product does. The third reality is leakage: a UV lamp and a media filter cannot help a house whose return ducts are pulling 120-degree attic air through every seam. We seal the return side as part of any Healthy Climate install in a pre-2000 house, because clean air that is also attic air is not the goal.

Sizing the pieces

  • Filter cabinet: sized to the system’s airflow so the pressure drop stays low; a bigger cabinet is better than a denser filter.
  • UV lamp: sized to the coil face it has to cover, mounted on the downstream side where the wet surface is.
  • Dehumidifier: sized to the house’s moisture load, which in a riverfront or beachside home is higher than the square footage suggests.
  • Ventilator: sized to the number of bedrooms and occupants, and only specified for houses built tight enough to need it.

Every piece is serviced on the same maintenance visits as the rest of the system, which is the point of buying the line from the dealer who installs it. Cook’s drives down from our Palm Coast headquarters, measures the airflow and humidity first, and quotes only what the readings call for. Call 866-266-5709.

Healthy Climate questions from Volusia homeowners

Can the Healthy Climate pieces go on a system that isn't Lennox?

The media cabinet, UV lamp and ducted dehumidifier can. The purification system that ties into the thermostat and the integrated fresh-air control work best on Lennox equipment. We will tell you which parts fit the system you have.

Does a clean coil really show up on the FPL bill?

Yes. A coil coated with the mold film that grows on every wet coil here transfers heat poorly, so the compressor runs longer for the same result. Keeping it clean with UV is one of the few air quality products that pays part of its own way.

My 1980s house has one return in the hall. Where does the cabinet go?

Either at the air handler with a transition, or at the ceiling grille where the return starts. If the return is badly undersized we enlarge it first, because a deep filter on a starved return just moves the restriction.

Is this overkill for a couple in a 1,400 square foot condo?

Probably, in full. A condo in Ormond-by-the-Sea with a closet air handler usually needs the media cabinet and the UV lamp and nothing else. The full set is for larger homes and for households with a medical reason to want hospital-grade air.
