AC Installation Portland | Manual J Sizing & Professional Install
AC installation covers the sizing and fitting of a central air conditioning system, ductless mini-split, or heat pump to your home's cooling load. Portland averages 15-25 days above 90°F each summer, and heat events keep pushing past 100°F. Properly sized air conditioning isn't a luxury anymore — it's a necessity.

Energy Trust rebates up to $3,000 and federal tax credits up to $2,000 reduce costs. NATE-certified technicians, 4.9-star rated across 1,400+ reviews since 2008.

AC Installation Process: What to Expect Step by Step
From your first phone call to enjoying cool air, here's exactly what happens during a professional AC installation with Efficiency Heating & Cooling.
Initial Consultation & Home Assessment
60–90 minutesA comfort advisor visits your home to evaluate your cooling needs. We inspect your existing HVAC system, ductwork condition, electrical panel capacity, and outdoor unit location. We measure every room, check insulation, count windows, and note sun exposure. This isn't a sales call — it's a thorough engineering assessment.
- Manual J load calculation to determine exact cooling needs
- Ductwork inspection for leaks, damage, and sizing adequacy
- Electrical panel evaluation (many Portland homes need a subpanel or circuit upgrade for modern AC)
- Discussion of your comfort priorities, budget, and any problem areas in your home
- We photograph the workspace for our installation team
System Design & Proposal
Same day or next dayBased on our assessment, we design a system tailored to your home and present 2–3 options at different price points. Every proposal includes equipment specifications, total installed cost, available rebates, financing options, and projected energy savings compared to your current system.
- Good-Better-Best options so you can choose what fits your budget
- All rebates and tax credits pre-calculated and subtracted from quoted price
- Financing pre-qualification available (soft credit check, no impact to score)
- Written warranty details for equipment and labor
- No pressure — proposals are valid for 30 days
Permits & Scheduling
1–3 business daysOnce you approve a proposal, we pull the required mechanical permit from your local jurisdiction (City of Portland, Clackamas County, Washington County, etc.). Oregon requires permits for all HVAC installations. We handle all permit paperwork and scheduling.
- Mechanical permit filed with local building department
- Installation typically scheduled within 3–7 days of approval
- Emergency installations available for system failures during heat events
- We coordinate with electricians if panel upgrades are needed
- Pre-installation checklist sent to homeowner (clear area around unit, etc.)
Professional Installation Day
4–8 hours (central) | 2–4 hours (ductless)Our NATE-certified installation crew arrives with all equipment and materials. We protect your floors and walls with drop cloths, remove the old equipment, and install the new system according to manufacturer specifications and Oregon mechanical code requirements.
- Old equipment removal and proper disposal (including refrigerant recovery per EPA regulations)
- New equipment placement and secure mounting
- Refrigerant line installation with proper brazing and leak testing
- Electrical connections with dedicated circuit if needed
- Condensate drain routing with proper slope and trap
- Thermostat installation and WiFi configuration
- Complete cleanup — we leave your home cleaner than we found it
Testing & Commissioning
30–60 minutesAfter installation, we thoroughly test every aspect of the system to ensure it's performing to manufacturer specifications. This step is critical — studies show that improper commissioning is the #1 cause of premature AC failure and reduced efficiency.
- Refrigerant charge verification using superheat/subcooling measurements
- Airflow measurement at each supply register
- Temperature differential check across evaporator coil (target: 15–20°F)
- Electrical draw verification (amps within manufacturer specs)
- Thermostat programming and operation verification
- Condensate drainage test to prevent water damage
Customer Walkthrough & Documentation
15–30 minutesWe walk you through your new system, showing you how to operate it efficiently, change filters, and recognize any issues that need attention. You receive complete documentation including warranty cards, permit receipts, and maintenance schedules.
- Thermostat operation tutorial and energy-saving settings
- Filter type, size, and replacement schedule
- Warranty registration (we handle manufacturer registration)
- Energy Trust rebate submission (we file on your behalf)
- Federal tax credit documentation for your tax return
- Maintenance plan enrollment with priority service benefits
Inspection & Follow-Up
Within 2 weeksThe local building department schedules a permit inspection to verify code compliance. We coordinate with the inspector and address any items if needed (rare with our installations). We also follow up with you after the first week to make sure everything is performing as expected.
- Building department inspection (required by Oregon law)
- 7-day follow-up call to check satisfaction and system performance
- First maintenance visit scheduled for optimal system longevity
- Ongoing support via our 24/7 service line
