If you're scheduling AC installation in Bay Minette, knowing what to expect on install day reduces friction for everyone. Whether your home is on a tight lot near the Courthouse Square downtown or on acreage out along the Highway 31 corridor, 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. Properties along the Tensaw River corridor and out toward the Hubbard's Landing area often have outdoor units 50+ feet from the indoor air handler. Longer linesets = more refrigerant, more attention to install detail.

Questions. Answered.

  • Can a Bay Minette AC installation really be done in one day?
    For most single-family homes around Bay Minette, yes — a straightforward changeout with a 2-tech crew runs from about 7:30 AM to mid-afternoon. The single-day timeline holds when we reuse the existing pad and lineset path and the ductwork doesn't need rework. Larger 5-ton systems, attic air handlers with tight access, or duct and electrical upgrades can push it into a second day, which we tell you at the quote, not on install day.
  • Do I need a permit to replace my AC in Bay Minette?
    Most residential changeouts in this part of north Baldwin County require a permit, and we pull it with Baldwin County before the crew arrives. The permit is posted on install day and closed out with paperwork at the walk-through. You don't have to chase any of it down — handling the permit is part of the job.
  • Why might a Bay Minette install need a longer lineset than a coastal one?
    Lots out toward the Tensaw River corridor and the rural stretches off the Highway 31 spine tend to be larger, and the outdoor unit can sit 50-plus feet from the indoor air handler. A longer copper lineset means more refrigerant and more brazed joints, so the pressure test and final charge weight matter even more. We measure the run and adjust the charge to the manufacturer's spec for that length.
  • Does Bay Minette's inland location change what equipment I should install?
    It does. Bay Minette sits far enough from Mobile Bay that salt-air corrosion is minimal, so the coastal-grade premium that makes sense in Gulf Shores usually isn't worth it here. What does matter is that winters near the courthouse square can dip below freezing more than the beach towns, so a heat pump should be sized for the cold-snap heating load, not just summer cooling.
