You signed the quote, your install is scheduled, and now you’re wondering what the next 8 hours actually look like. Every HD contractor sells “professional installation” but the experience varies wildly. Here’s what a JCE install looks like, start to finish, on a typical Hesperia or Apple Valley AC replacement.
Two-sentence answer: a single-system AC replacement on a typical HD home takes 7-9 hours from crew arrival to commissioning complete. Multi-system or heat-pump installs run 8-10 hours. We walk the home with you at the start and end and update you mid-day if anything changes.
Below is the actual process, the same one our crews run on every AC install in Victorville and across the High Desert.
Step 1: Site visit + quote (1-2 days before signature)
Before any install, we send a tech (usually me or our lead installer) to your home for a 45-90 minute estimate visit. What happens:
- Walk every conditioned room, measure square footage if it’s not on the plans
- Count and measure windows, note orientation (north/south/east/west matters for sizing)
- Pull existing equipment data plates: model number, year, refrigerant type, tonnage
- Open the air handler/furnace to check coil condition and ductwork condition
- Climb into the attic if access allows, photograph duct runs and insulation
- Run Manual J load calc on the tablet while still at your kitchen table
- Pull current SCE / SoCalGas / RPU rebate sheets that apply
- Quote 2-3 equipment options at different efficiency tiers
- Email the quote PDF before we leave the driveway
You don’t sign anything during the visit. We email the quote and follow up 2-3 days later. No pressure, no “today-only” pricing.
Step 2: Install scheduling (after signed quote)
Once you sign, we schedule the install. Typical lead time:
- Standard equipment (Goodman, Rheem): 5-10 business days
- Mid-tier equipment (Bryant, Trane, Daikin): 7-14 business days
- Premium equipment (Carrier Infinity, Bosch IDS, Mitsubishi): 10-21 business days
We pull permits during this window. Most HD jurisdictions (Hesperia, Apple Valley, Victorville) issue HVAC permits within 2-3 business days. Riverside and the IE cities run slightly slower, 4-7 days.
You get a confirmed install date once permit + equipment delivery are both in hand.
Step 3: Install day (start to finish)
Crew arrives 7-8 AM. Here’s the actual sequence on a typical AC replacement:
7:30-8:00 AM - Pre-install walkthrough
Lead installer arrives 15-30 minutes before the truck. We:
- Walk the planned install path (no surprises)
- Lay drop cloths from the front door to the air handler location
- Set up shoe covers
- Confirm power-off windows with you
- Confirm pet/child management plan (gates closed, etc.)
- Pull permit copy out for inspector if a same-day inspection is scheduled
8:00-10:00 AM - Demolition of old equipment
- Refrigerant recovery from old system into EPA-certified recovery tank
- Power-off at the disconnect
- Disconnect old outdoor unit, remove from concrete pad
- Disconnect old indoor unit (coil + air handler), remove
- Inspect and clean ductwork at the air handler connection
- Photograph existing condition before any new install
10:00 AM-12:00 PM - New equipment set
- Position new outdoor condenser on existing pad (or set new pad if needed)
- Hoist new indoor air handler/coil into place
- Run new refrigerant line set if old one is undersized or damaged
- Connect refrigerant lines, flare or braze joints
- Connect condensate drain line (often replaced if old PVC is rotted)
- Mount new electrical disconnect outside
12:00-1:00 PM - Lunch break + start refrigerant work
- Crew lunch (off-site, 30 min)
- Pressure test refrigerant system with nitrogen to 350 PSI
- Confirm no leaks before evacuation
1:00-3:00 PM - Refrigerant + electrical + plumbing
- Evacuate refrigerant lines with vacuum pump to 500 microns
- Charge refrigerant to manufacturer-specified weight (not pressure, weight)
- Wire electrical: condenser, air handler, thermostat
- Install new thermostat
- Pour fresh sand pad if outdoor unit moved
3:00-4:00 PM - Commissioning
- First startup: visual + audible inspection
- Measure superheat and subcooling (verify proper charge)
- Measure indoor blower amp draw (verify proper airflow)
- Measure supply + return temperatures (verify proper delta-T, target 18-22°F in HD)
- Run system 30 minutes minimum to confirm normal operation
- Photograph data plates, charge weight, gauge readings
4:00-5:00 PM - Walkthrough + paperwork
- Walk you through thermostat setup (Wi-Fi connect, schedule, app pairing)
- Demonstrate filter location + size
- Hand you packet: warranty registration, rebate paperwork copies, equipment data sheets, maintenance recommendations
- Submit rebate forms to SCE/SoCalGas/RPU same day or next business morning
- Email install photos within 24 hours
Crew leaves around 5 PM. Total time on-site: 8-9 hours for AC-only, 9-10 hours for heat pump or AC+furnace combined.
Step 4: After install
What happens in the next 30 days:
- Day 1-2: We submit rebate paperwork
- Day 7-10: City inspector visits for final permit sign-off (if required by jurisdiction). We meet them.
- Day 14-21: SCE/SoCalGas rebate confirmation arrives. Check is 4-10 weeks out.
- Day 30: We call you for a 30-day check-in. Anything weird? Anything to tweak? Free service call if needed.
After 30 days, you’re on our standard maintenance recommendations: annual tune-up (spring or fall), filter changes every 60-90 days.
What to expect from a less-good install
For comparison, here’s what we hear from homeowners who had bad installs done by other contractors before us:
- Crew showed up at 11 AM, left at 8 PM, didn’t finish (came back day 2)
- No drop cloths, footprints in carpet, hallway dust everywhere
- No commissioning (no superheat/subcooling measurements, no run-time verification)
- Wrong refrigerant charge (over or under, system ran but inefficiently for months)
- No data-plate photos, no paperwork, no rebate filing
- Old equipment dumped at the curb, customer’s problem to haul
- Showed up to wrong house first, didn’t double-check the address
We don’t do those things. Process matters.
