What Gretna homeowners need to know about AC installation costs, system sizing, and getting the job done right the first time.
Gretna is one of the fastest-growing communities in Sarpy County — and with that growth comes a lot of HVAC questions. Whether you are moving into a newly built home and need your first system, replacing aging equipment in an established neighborhood, or dealing with a unit that gave out on a hot Friday afternoon, this guide is for you.
At DL Heating & Cooling, we serve Gretna homeowners regularly. From AC installations and furnace repairs to water heater service and ductwork, we cover everything your home needs to stay comfortable through Nebraska's extreme seasons.
A new central air conditioner installed in a typical Gretna home costs $4,000 to $8,000 depending on the system size, efficiency rating (SEER), and whether any ductwork work is needed. A full furnace and AC replacement together runs $7,000 to $14,000. Heat pump systems that handle both heating and cooling cost $4,500 to $10,000.
Several factors affect the final price for a Gretna installation:

This is the most important question in any AC installation — and the one that too many contractors skip. Most Gretna homes require a 2.5 to 4 ton central AC system, but the right size for your home depends on more than just square footage.
An undersized unit runs constantly, struggles to cool your home on the hottest days, and wears out faster. An oversized unit short-cycles — it cools the air quickly but shuts off before removing humidity, leaving your home feeling clammy even at 72 degrees. It also costs more to run and has more mechanical wear from the frequent starting and stopping.
A proper load calculation takes into account your home's square footage, ceiling height, insulation quality, number and orientation of windows, local climate data, and more. DL Heating & Cooling performs a Manual J load calculation on every installation — not a guess, not a rule of thumb.
Gretna has a mix of newer construction (many built in the 2010s and 2020s) and older homes along the original city core. Newer construction tends to have better insulation and tighter envelopes, which can allow for a smaller, more efficient system. Older homes often have ductwork designed for lower-efficiency equipment and may benefit from a ductwork inspection before a new system is installed.
If you are in a newer development off Highway 6 or near the Gretna Public Schools campus, your builder-grade equipment may still be within its expected lifespan — but worth evaluating if you are seeing high energy bills or uneven cooling. Read our repair vs. replace guide →
A large portion of Gretna's housing stock was built during the 2000s and 2010s, meaning the original HVAC equipment installed by builders is now 10 to 20 years old. Builder-grade systems are typically installed to meet minimum code — not to maximize efficiency or longevity. If your system is over 12 years old and has needed multiple repairs in the last two years, it is worth getting a replacement estimate to compare the long-term costs.
Gretna summers combine high temperatures with high humidity — a challenging combination for any HVAC system. If your home feels sticky even when the AC is running, the cause is often an oversized system that does not run long enough to dehumidify, low refrigerant, or a dirty coil. A properly maintained and correctly sized system should keep indoor humidity between 40% and 50%.
In many cases, a service call that starts as an AC issue also involves the furnace — especially with older equipment. When we replaced a full AC unit for a Gretna homeowner recently, we also took care of a furnace motor replacement the same day, getting everything handled in a single visit. If your equipment is aging, it often makes sense to evaluate the whole system rather than just the piece that failed.
Homes built before 2000 often have ductwork that has developed leaks, loose connections, or insulation breakdown over the years. If some rooms in your home are always warmer or cooler than others, or your energy bills are climbing without explanation, duct leakage is often the culprit. We inspect, seal, and repair ductwork to restore proper airflow throughout your home. Learn about our ductwork services →
We install Oxbox by Trane systems as our preferred brand for Gretna homeowners. Oxbox is built on Trane's engineering platform and manufactured in the same facilities — you get Trane-level reliability at a price point that works for real families. The warranty does not require registration and transfers to the new owner if you sell your home, which adds value at resale in Gretna's active real estate market.
If your furnace is within a few years of your AC in age, replacing both at the same time almost always makes financial sense. Here is why:
We will give you an honest evaluation of both systems during your free estimate. If your furnace has several good years left, we will tell you. We never recommend a replacement that is not in your best interest.
