A new air conditioner should be a fifteen-year decision, and the installation day determines most of it. What most homeowners never hear is that a poorly installed system gives up a large slice of its rated efficiency before it ever cools a room: an oversized unit short-cycles, dehumidifies poorly, and leaves a Metairie house cold but clammy; an undersized one runs flat-out and never catches up on the worst afternoons. That is why Metairie HVAC starts every installation with a real load calculation, measuring your home's square footage, insulation, window exposure, and duct system, instead of matching the tonnage bolted to the wall by the last contractor.
Equipment selection comes next, and we keep it honest. Today's systems are rated under SEER2, and the jump from a builder-grade single-stage unit to a multi-stage system buys quieter operation, longer and gentler cycles, and far better humidity control, worthwhile for some homes and unnecessary for others. Our experienced technicians walk you through the real trade-offs, then install to the details that decide performance: a correctly sized and pressure-tested line set, a deep vacuum pulled and verified with a micron gauge before any refrigerant flows, the charge dialed in by weighed-in measurement and confirmed with superheat and subcooling, a properly trapped and sloped condensate drain with a float safety, and airflow verified against static pressure so the new equipment is not strangled by the old ductwork.
We finish with commissioning, not just a thumbs-up: temperature split measured, amp draws recorded, thermostat configured, and the whole system run through complete cycles while we watch it work. Where a permit applies, we handle the process, and we haul away the old equipment when the job is a changeout.

Warning Signs for AC Installation
Recognizing the warning signs early can save you time, money, and prevent significant damage to your property. Keep an eye out for the following clues that it's time to bring in an expert:
- A system that has already passed its twelfth to fifteenth summer
- A major repair, like a dead compressor or leaking evaporator, on aging equipment
- Hot spots and warm rooms the AC can never catch up with
- Summer energy bills that keep rising as comfort drops
- More frequent repairs, each one costing more than the last
- An older unit that runs on phased-out R-22
- Rooms that feel cool but clammy, often a sign the unit is oversized
- The AC runs constantly on hot days and never reaches the setpoint
Act Before It Gets Worse
A failing capacitor, clogged condensate drain, or dirty flame sensor rarely fixes itself and usually gets more expensive to address the longer it runs. Don't wait, get Metairie HVAC on the phone at (504) 531-6049 and we'll take a look right away.

The Benefits of Professional AC Installation
A new AC can blow cold on day one and still be doomed. Moisture left in a line set that was never properly evacuated forms acid that slowly destroys the compressor. A refrigerant charge set by feel rather than by weight drains efficiency with every cycle. An oversized system, chosen without a load calculation, short-cycles itself into an early grave and never dries the air. Installation is where a system's future gets decided, and none of these errors reveal themselves until the repair bills and utility costs start climbing.
Our experienced technicians do the unglamorous steps that make equipment last: nitrogen pressure testing before evacuation, a micron-gauge-verified vacuum, charge set by weight and confirmed against measured superheat and subcooling, condensate drainage with a proper trap and overflow protection, and airflow verified with static pressure readings rather than a hand held over a register. Refrigerant handling itself is federally regulated, and the recovery and evacuation equipment involved is not a hardware-store purchase. Done right, an installation disappears into fifteen quiet years of cold air, and that is the outcome we commission every job to deliver.
Our AC Installation Process
We follow a proven process to ensure every repair and installation is completed to the highest standards. Here's what you can expect when you choose Metairie HVAC:
Home Assessment & Sizing
A real load calculation, based on size, insulation, windows, and orientation, tells us the right capacity. We inspect the ducts during the same visit.
Equipment Choices & Quote
You see single-stage, two-stage, and variable-speed choices side by side, with a plain explanation of the SEER2 trade-offs and a firm installed price. There is no pressure to overbuy.
Installed to Spec
The line set is pressure-tested, a deep vacuum is pulled and confirmed with a micron gauge, the refrigerant is weighed in, and the condensate drain is trapped and fitted with a float switch.
Commissioning & Walkthrough
Startup includes checking superheat, subcooling, amp draws, airflow, and temperature split. Then we set up the thermostat, show you how everything works, and haul off the old unit.
How to Prevent AC Installation Problems
A little routine maintenance goes a long way toward avoiding a mid-season breakdown. Put these technician-approved steps to work around your property:
- Keep supply and return vents open to preserve the airflow balance set at commissioning
- Have a technician check the system every spring so charge and amp draws stay where they were set
- Hose off the outdoor unit occasionally and keep plants away from every side
- Start a regular filter schedule on day one to protect the new coil from restricted airflow
- Keep setpoints steady and moderate rather than making the system recover from big swings in peak heat
- Address small issues early; a soft capacitor caught in April never becomes a July breakdown
- Clear the condensate drain every spring before a clog can trip the float switch
DIY vs. Professional AC Installation
A homeowner can swap a filter with ease, but diagnosing capacitors, refrigerant charge, control boards, and error codes calls for the equipment and know-how only a pro brings. Consider the following comparison:
| Factor | DIY Attempt | Professional Service |
|---|---|---|
| Equipment Sizing | Rule-of-thumb tonnage | Capacity matched to your home's actual load |
| Evacuation | Moisture trapped in the lines | Micron gauge confirms a deep vacuum |
| Charge | Beer-can-cold guesswork | Set by weight, checked with superheat and subcooling |
| Ductwork | Airflow never checked | Static pressure measured and corrected |
| Drainage | Untrapped drain, ceiling damage later | Proper trap, slope, and float switch |
| Startup | Turned on and left alone | Full commissioning with recorded readings |
