How Long Does AC Installation Take in Bay Minette? Day-by-Day Timeline

If you're scheduling AC installation in Bay Minette, knowing what to expect on install day reduces friction for everyone. Most residential installs in north Baldwin County take a single day with a 2-tech crew. Here's the full timeline so you know what's happening and when.

Pre-install: 1-3 weeks before

What we do before the install crew arrives:

• Manual J load calc completed. Sized to your specific Bay Minette home.
• Equipment ordered and confirmed delivered. AHRI-matched components.
• Permits pulled with Baldwin County. Most residential installs require permits.
• Disposal arrangements for old system. Refrigerant recovery + responsible disposal.
• Schedule confirmation 2-3 days before install day.

What you do as the homeowner:

• Clear access to the indoor air handler closet. Move boxes, items in attic if applicable.
• Clear 24" perimeter around outdoor unit location.
• Plan to be home for at least the start and end of the install. Not strictly required to be present continuously, but useful for any decisions that come up.
• Secure pets in a closed room away from work areas.
• Note any ductwork concerns you want addressed during the install.

Install day: 7:30 AM to ~4:00 PM

7:30 - 8:00 AM: Arrival and setup

Crew arrives, walks the property with you, confirms the install plan, sets up tools and drop cloths. Brief check on any last-minute questions or concerns. Permits posted as required.

8:00 - 9:00 AM: Old equipment removal

• AC turned off at thermostat and breakers
• Refrigerant recovered from old system (EPA requirement — captured for proper disposal, not vented)
• Electrical disconnections
• Old condenser removed from outdoor pad
• Old indoor air handler removed from closet
• Existing lineset evaluated (often replaced for new system)
• Old equipment loaded for haul-away

9:00 AM - 12:00 PM: New equipment installation

The biggest chunk of the day:

• New outdoor condenser placement. New pad if needed (most Bay Minette installs reuse existing pad).
• New indoor air handler placement. Coil, blower, and electronics integrated.
• New lineset run. Copper refrigerant lines from outdoor to indoor units. New is preferred — old linesets can have moisture or contaminants from the previous system.
• Brazing all refrigerant connections. This is where install quality really matters. Bad brazing = future refrigerant leaks. Should be done with nitrogen flow to prevent oxidation inside the lines.
• Electrical connections. Disconnect, breaker, control wiring all wired correctly.
• Condensate drain installation. Including float switch safety.
• Insulation of lineset with proper thickness for our climate.

12:00 - 12:30 PM: Lunch break

Crew breaks. You can typically come and go from areas of the house that aren't directly impacted.

12:30 - 2:00 PM: System pressure test and evacuation

This step separates good installs from bad ones:

• Nitrogen pressure test of refrigerant circuit. System pressurized to manufacturer spec, held for 15-30 minutes to confirm no leaks at any joint.
• Vacuum evacuation of the refrigerant circuit. System pulled down below 500 microns to remove all moisture and non-condensables.
• Hold vacuum to verify integrity. No vacuum loss = system is sealed and dry.
• Refrigerant charge. Specific weight per manufacturer spec, factoring in lineset length.

A contractor who skips or shortcuts this stage installs problems. Ask whether they're doing a full evacuation.

2:00 - 3:00 PM: Commissioning

System startup and verification:

• Initial startup. System turned on, both indoor and outdoor units verified running.
• Refrigerant pressure verification in cooling mode. Suction and head pressures match spec.
• Superheat and subcooling measurements. Confirms system is properly charged.
• Airflow verification. Static pressure measured, blower speed adjusted if needed.
• Temperature differential check. Air at supply registers should be ~18-22°F cooler than return.
• Thermostat programming. New thermostat set up, smart features connected if applicable.

3:00 - 4:00 PM: Cleanup and walk-through

• Tools removed
• Cardboard, packaging, debris hauled away
• Old equipment loaded for proper disposal
• Walk-through with you: explain new system, hand over manuals, walk through warranty terms
• Permit close-out paperwork
• Payment processed

What can extend the timeline

Some Bay Minette installs run longer than a single day:

• Larger systems (5+ tons) may need more time for line work
• Difficult equipment placement (attic with limited access, basement crawlspace)
• Ductwork modifications required to match new equipment
• Electrical service upgrades required
• Multi-zone or specialty installs (mini-split, geothermal)

For these, the install team will give you a multi-day estimate during quote.

What to expect on day 2 (if multi-day)

Multi-day installs typically include:

• Day 1: Old removal + new equipment placement + initial connections
• Day 2: Final connections, pressure test, evacuation, charge, commissioning, cleanup

System is not operational between days. Plan accordingly.

Bay Minette-specific notes

Three things specific to north Baldwin installations:

1. Less salt-air concern. Bay Minette is far enough inland that standard equipment is fine — coastal-grade premium isn't required.

2. True four-season climate. Bay Minette winters can hit freezing more than coastal areas. Heat pump sizing should account for cold-snap heating loads, not just cooling.

3. Larger lots = potentially longer linesets. Some Bay Minette properties have outdoor units 50+ feet from indoor. Longer linesets = more refrigerant, more attention to install detail.
