Air Conditioning Installation & Replacement

AC Installation in New Orleans, LA: Honest, Same or Next Day Air Conditioning Installation

Need a new AC fast? Keefe’s installs most full systems same or next day across New Orleans, with honest options and a clear written quote before any work begins.

A new air conditioner is a big purchase, and in New Orleans it is also one of the most important. Our summers run hot, sticky, and long, so the system you choose has to do more than just blow cold air. It has to pull humidity out, run efficiently month after month, and stand up to salt air, storms, and the kind of heat that does not let up until October. Keefe’s has been installing AC systems in New Orleans homes since 1979, and we know exactly what it takes to get this right.

When you call us, a real person picks up. We can usually have a comfort advisor at your home the same day to look at your current system, talk through your goals, and put together honest written options. Most full AC installations are completed in a single day, often as soon as the next day from your first call. We provide same or next day AC installation across the Greater New Orleans area, including Metairie, Kenner, Harahan, Slidell, and the Northshore.

Same or Next Day AC Installation in New Orleans

If your AC has stopped working in the middle of summer, you do not have time to wait a week. Keefe’s keeps a wide range of systems and parts in stock so most full installs can happen same or next day across the New Orleans metro.

Is It Time for a New Air Conditioner?

A lot of homeowners are not sure whether to keep paying for repairs or finally make the move to a new system. There is no one-size answer, but there are clear signs your AC is telling you it is ready to be replaced. If a few of these sound familiar, replacement is probably the better long-term call.

  • Repairs are stacking up: If you have paid for two or more major repairs in the past two years, the system is starting to nickel-and-dime you, and the next breakdown could be the big one.
  • Bills keep climbing: Higher Entergy bills with the same usage almost always mean your system is losing efficiency. New high-SEER systems can cut cooling costs noticeably, especially in our long summers.
  • Some rooms never feel right: Hot bedrooms, cold kitchens, or a back of the house that just will not cool down usually point to either a sizing problem or a duct problem, and a new install is the right time to fix both.
  • It is loud or smells off: Grinding, rattling, or musty smells are not normal. They mean a part is failing or the system has moisture issues that are not going to fix themselves.
  • It is over 10 to 15 years old: Most AC systems in New Orleans last 10 to 15 years because of how hard they have to work here. Once you cross that line, replacement starts to make more sense than repair.
  • It uses old R-22 refrigerant: R-22 has been phased out, so any leak repair is expensive and slower to source. New systems all use R-410A or R-454B, which are easier and more affordable to service.
  • Your home feels sticky even when cool: If your thermostat says 72 but the air still feels heavy, your system is not pulling humidity. A right-sized new system, sometimes paired with a dehumidifier, fixes that.

What Greater New Orleans Homeowners Can Expect From a Keefe’s AC Installation

A good AC install starts long before the new equipment shows up at your house. Here is exactly what to expect from us, step by step, so there are no surprises on install day.

  1. 1
    In-Home Assessment. A comfort advisor visits your home, looks at your current system, checks your ductwork, asks about hot or cold spots, and listens to what is actually bothering you about the way your home feels.
  2. 2
    Accurate Load Calculation. We run a Manual J load calculation, the industry standard, so the new system is sized correctly for your real home, not just a copy of the old one.
  3. 3
    Honest System Options. You get good, better, and best options in writing, with the differences explained clearly. No pressure, no upsells you did not ask for, just real choices.
  4. 4
    Removal of Old Equipment. On install day, we lay down floor protection, remove your old AC carefully, and haul it away. We also recover any old refrigerant the right way.
  5. 5
    Precise Installation. We install the new outdoor unit, indoor air handler, refrigerant lines, and thermostat to manufacturer specs. If you need a panel upgrade or a new pad for the condenser, our in-house electricians handle it the same day.
  6. 6
    Testing and Calibration. Before we leave, we test airflow in every room, verify the system is cooling and dehumidifying correctly, and calibrate the thermostat so the temperature you set is the temperature you get.
  7. 7
    Homeowner Walkthrough. We show you the new system, walk you through the thermostat, register your warranty, and answer every question you have. You will know exactly what was installed and how to use it.

Frequently Asked Questions About AC Installation

How long does AC installation take in New Orleans?

Most full AC installations in New Orleans are completed in a single day, often as soon as the next day from your first call. A standard system swap usually takes 4 to 8 hours. If your install includes new ductwork, an electrical panel upgrade, or a heat pump conversion, plan for one to two days. We always give you a realistic timeline before we start.

Can you install a new AC system the same day or next day?

In most cases, yes. Keefe’s keeps a wide range of AC systems and parts in stock so we can install most full systems same or next day across New Orleans, Metairie, Slidell, and the Westbank. If your AC has gone out in the middle of summer, getting your home cool again should not take a week.

What factors affect the cost of a new AC system?

A few main things drive the cost of a new system. The size of your home and the size of the system, the SEER efficiency rating, the brand and warranty, the condition of your existing ductwork, and any related work like a new electrical panel or condensate line. We give you good, better, and best written options so you can see exactly what each one includes.

Do you offer financing on AC installation?

Yes. Keefe’s offers flexible financing options on new AC installations through several lending partners. Approved customers can choose terms that fit their monthly budget, including options with low interest for a set period. Ask your comfort advisor and we will walk you through the options when we put together your written estimate.

How long will my new AC system last?

In New Orleans, a properly sized and well-maintained AC system typically lasts 12 to 15 years. Heat pumps land in a similar range. The two biggest factors are right-sizing at install and yearly maintenance. Systems that are oversized, undersized, or skipped on tune-ups tend to fail much sooner.

Will a new AC system lower my energy bills?

Usually, yes. New high-efficiency systems use significantly less electricity than systems built 10 to 15 years ago, and SEER2 ratings have continued to improve. Combined with a right-sized system, sealed ductwork, and a properly calibrated thermostat, most homeowners notice a clear drop in their summer Entergy bills.

Should I replace just the outdoor unit or the whole system?

The outdoor unit and indoor coil are designed to work as a matched pair. Replacing only one can lower efficiency, void the new warranty, and shorten the life of both pieces. In almost every case, replacing the system as a matched set is the smarter long-term choice.

Do I need new ductwork with my new AC?

Not always. We inspect your existing ductwork during the in-home assessment. If it is sealed, the right size, and in good shape, we keep it. If we find leaks, undersized runs, or crushed sections that hurt airflow, we will show you the issue and explain what fixing it would do for comfort and bills.

Do you offer second opinions on AC installation quotes from other companies?

Yes, and it is free. Bring us any written proposal and we will go through it with you, line by line, and let you know honestly whether the size, brand, and price are a fair deal for your home. There is no obligation to use Keefe’s afterward.

What AC brands do you install in New Orleans?

All of the major ones, including Carrier, Trane, Lennox, and Mitsubishi. We are factory authorized on multiple lines, so warranty registration is handled in-house when you book the install.
