Before Cook's installs a furnace, it asks whether you need one
In most of this territory a heat pump heats the house for less than a furnace does. Cook's installs furnaces where they belong and says so where they don't.

Furnace or heat pump: the comparison this territory forces
Put the two side by side on a January morning in Live Oak, 28 degrees outside. The gas furnace lights, blows air at 120 degrees, and the house is warm in minutes. The heat pump pulls heat from cold air, blows at 95, and takes longer. On that morning the furnace wins on comfort.
Now run the same two systems over the whole year. The furnace sits idle 340 days. The heat pump heats the house on the 40- and 50-degree mornings, which are the bulk of the territory’s “winter,” for a fraction of what either the furnace or electric strips would cost, and it’s the same machine that cools the house all summer. Over a year the heat pump wins on money almost everywhere Cook’s works.
That’s why furnace installation at Cook’s begins with a question rather than a quote.
The decision tree when the old furnace fails
Is there gas at the house? If not, a furnace means propane, a tank and a delivery contract. For most homes without existing gas, a Lennox heat pump is the answer, and the conversation moves to the heat pump installation page.
Gas is there. Is the existing furnace the only heat, with a separate air conditioner? Then the choice is between a new furnace paired with a new air conditioner, or a dual-fuel system: a heat pump that does most of the heating and a furnace that takes over on the coldest nights. Cook’s prices both.
Does the owner want gas heat specifically? Some do, for the hot supply air or because the kitchen and water heater are already gas. A Lennox gas furnace with a matched coil and air conditioner is a legitimate choice, and Cook’s installs it properly.
Is the furnace in a manufactured home or an addition? Electric furnaces and package units enter the picture, and the right answer is often a package heat pump.

What Cook’s installs
Lennox gas furnaces, in single-stage, two-stage and variable-capacity lines, matched to a Lennox coil and outdoor unit so the system is engineered together rather than assembled from parts. Dual-fuel systems pair a Lennox heat pump with a Lennox furnace and a thermostat that manages the changeover. Propane conversions are done at install where the home uses LP. Specific model numbers appear on your quote, not on this page. Ask whether Cook’s installs furnaces of other brands on request. [[CONFIRM WITH JERRY]]
Every furnace install includes the venting and combustion-air work code requires, a condensate drain on high-efficiency models, a gas line sized and leak-tested, and a startup with combustion analysis so the furnace leaves the first visit burning clean.

Residential and commercial
Home furnace installs are a day’s work, sometimes two when a gas line or flue has to be run. Commercial gas heat is almost always part of a rooftop package unit, replaced as a whole with a crane and scheduled around the business. Cook’s handles both, with the commercial side documented per unit.
Warranty notes
Lennox furnaces carry a parts warranty and a separate, longer heat exchanger warranty, both registered by Cook’s at install so the extended registered terms apply. Labor is covered by Cook’s; ask for the term in writing. [[CONFIRM WITH JERRY]] Annual maintenance is a condition of most manufacturer warranties; Cook’s keeps the record.
Financing and credits
Cook’s offers financing with low monthly payments on new heating systems, including dual-fuel pairings; the lender and terms are discussed at the estimate and never published. High-efficiency equipment may qualify for utility programs, which Cook’s will point you to without guessing at the amount; the federal tax credit is off the list since the end of 2025. Estimates on new systems are free in every market.

Furnace replacement questions
My house has gas. Should the new heat be a furnace or a heat pump?
Usually both, as a dual-fuel system: a Lennox heat pump that handles most heating days cheaply, switching to the gas furnace below a set outdoor temperature. If you want one piece of equipment, a heat pump alone is the lower-cost heat in this climate for all but a handful of nights.
How efficient a furnace is worth paying for here?
Less than up north. A furnace that runs a few hundred hours a year doesn’t accumulate the savings a 98-percent model earns in Minnesota. Cook’s typically recommends a solid mid-efficiency Lennox furnace and puts the premium into the cooling side, which runs 2,500 hours.
Can a furnace be installed where the old air handler was?
Often, with a gas line and a flue added. Attic and closet installs each have code requirements for clearance, combustion air and venting that the estimate visit confirms.
Do you install oil furnaces?
Oil heat is rare in this territory and Cook’s doesn’t recommend new oil equipment. Ask whether an existing oil furnace can be serviced or replaced in kind. [[CONFIRM WITH JERRY]]
