What to Expect During an AC Installation: Timeline, Disruptions, and Tips

What to Expect During an AC Installation: Timeline, Disruptions, and Tips

Planning a new AC install in Snohomish County, WA? Here’s your step‑by‑step guide to help you stay cool and confident from start to finish.

1. Scheduling & Pre‑Install Prep 

Booking Your Install Day

Once you decide to move forward, our team helps you pick a day that’s convenient. We lock in your appointment, send a reminder, and give you a prep checklist.

Your Pre‑Install To‑Do List

To ensure a smooth install, all you need to do is:

  • Clear 3–4 feet around indoor/outdoor units.
  • Ensure safe, easy access—please unlock gates, dimmers, pets out of the way.
  • Let us know about sensitive items (pictures, breakables).

Getting prepped lets us work faster, cleaner, and avoid surprises on install day.

 

2. Install Day: Timeline & What Happens

Morning: Arrival & Setup

Our crew arrives on time (usually between 8–9 AM), greets you, and walks you through the day’s plan. They wear shoe covers, lay down drop cloths, and set up a clean workspace.

Old Unit Removal (1–2 Hours)

  • Turn off the system and disconnect power.
  • Carefully remove old indoor/outdoor units.
  • If replacing the coil or ducting, they’ll tag and take those too.
  • Debris or old parts are neatly placed outside for disposal.

Coffee Break & Progress Check

You’ll get a quick QC check—inspect the area, ask questions, check contractor’s findings.

 

New Unit Installation (4–6 Hours)

  • Install new evaporator coil and condenser.
  • Connect ducting, wiring, refrigerant lines.
  • Seal everything to code and to prevent energy loss.

Breakdown & Safety Test (1 Hour)

  • Vacuum and wipe work area.
  • Run airflow and refrigerant pressure tests.
  • Deep clean filters, wipe control surfaces.
  • Technician gives a recap, shows your meter, tests the thermostat.

Wrap‑Up & Walk‑Through

We’ll walk you through:

  • Thermostat usage and settings.
  • Filter schedules.
  • How to spot early signs of trouble.
  • Any available maintenance or warranty plans.

By mid‑afternoon—you’ll be enjoying your cool new system.

3. What to Expect: Disruptions & Comfort Tips

Noise & Foot Traffic

Expect shuffling, compressor noise, tool sounds, technicians… a normal install day is far from silent.

Tip: Close bedroom windows and use fans to help mask noise.

Short Power Interruptions

Power will be off briefly—during old unit shutdown and connection of the new system.
Tip: Plan around any urgent appliance use.

Dust Control

Even with drop cloths and PPE, you might see a light layer near work zones.
Tip: Use a vacuum or Swiffer in key areas after install.

Cool‑Down Recovery Time

New units take about 30 minutes to kick into full cooling.
Tip: Set the thermostat 2–3°F lower than desired and let blower run for 10–15 minutes to spread cooled air quickly.

4. Post‑Install Care: Maintenance & Warranties

Maintenance Tip: Keep Filters Clean

Replace or clean your air filters every 1–3 months. Clogged filters stress your system and raise utility bills.

Summer Tune‑Up Reminder

We recommend scheduling annual maintenance each spring or late summer. Ideal timing: before peak usage hits.

Warranty & Service

Most AC systems include 5–10 year parts warranties.
Our installs include a 1‑year labor warranty—and we’ll walk you through your coverage.

A: Absolutely—our crew uses approved cleaners, and we’d be happy to walk you through everything.
