Two electric bills, one product line: choosing Lennox equipment on either side of the Orange Park town line

Read the bill before the brochure

A heating and cooling product page usually opens with a list of equipment. This one opens with two envelopes, because the electric bill is what sends most Orange Park homeowners to this page in the first place.

If your address is inside the Town of Orange Park, along Kingsley Avenue or in Ridgewood or Forest Hammock, your power comes from JEA. If you are in Lakeside, Bellair-Meadowbrook Terrace, Middleburg or most of unincorporated Clay County, it comes from the Clay Electric Cooperative. The bills look different, the rebate programs are different, and the kilowatt-hours on them tell the same story: a system that used to carry the house through a 91-degree afternoon is now running most of the day to do it.

Each piece of equipment Cook’s installs answers one part of that story: the outdoor unit decides how efficiently heat leaves the house, the indoor unit decides how air moves and how much moisture comes out of it, and the thermostat and add-ons decide how often the whole thing runs. A bill that jumped is usually one of the three failing, rarely all of them.

Replacing in a 1972 Bellair ranch versus specifying for a Lake Asbury build

Clay County grows along two tracks at once. New subdivisions are going in south of Middleburg and toward Green Cove Springs ahead of the First Coast Expressway, while the original block ranches off Blanding Boulevard are on their third or fourth system.

• Retrofit. The equipment has to fit the closet, garage platform or attic that already exists, use the ductwork that already exists, and work with a panel that may date to the house. In Bellair and Ridgewood that often means a compact air handler and a condenser pad that gets moved out from under a dripping eave.
• New construction. The equipment can be chosen first and the house built around it: a variable-speed heat pump, a sealed return path, a thermostat located where the family actually lives. We work with builders on this, and with owners who are acting as their own.

The product is the same Lennox line in both cases. What differs is how much of the house we are allowed to fix on the way in.

Ask which equipment fits the house

The ducts you already own

Nothing in the Lennox catalog can out-run a bad duct system, so we look at the ducts before we quote the equipment. Three patterns repeat across the Orange Park mailing area:

1. One hallway return, undersized. Standard in 1960s and 1970s concrete-block ranches on the original town streets. A new high-efficiency system starved for return air will trip on low airflow or freeze its coil.
2. Flex duct draped across a hot attic. The 2000-2007 Oakleaf Plantation and Fleming Island production homes were built fast, and the attic runs sag, kink and pull loose at the boots. A twenty-degree temperature rise between the air handler and the far bedroom is common.
3. Crossover ducts under manufactured homes. Common in Middleburg and Clay Hill, and the first thing to fail after a flood or a hard winter.

Where the ducts are the problem we say so, because selling a two-stage system to a house that leaks a third of its air into the attic wastes your money and our reputation.

Sizing is a calculation, not a guess from the old nameplate

Sizing starts with a load calculation built from the orientation of the house, the windows, the insulation, the ceiling heights and the number of people in it. Then we pick the Lennox tier: single-stage for a tight budget on a small ranch, two-stage for most of Lakeside and Orange Park South, variable-speed where humidity control or noise matters most. Ask about current utility and manufacturer incentives when we quote; the rebate programs change yearly, and whether a given program pays through the contractor or directly to you depends on the utility [[CONFIRM WITH JERRY]].
