About ac installation

AC installation covers full system replacements (condenser + air handler + new line set) and brand-new installs in homes that didn't have central air. The single biggest predictor of comfort and efficiency is correct sizing — we run a Manual J load calculation on every install. Cheaper companies skip this step and you live with the consequences for 15 years.

When to call us

Signs you need ac installation

If any of these sound like your situation, give us a call or text. Many of these are quick fixes if caught early.

  • System is 12+ years old and breaking down regularly
  • Repair bill is more than half the cost of replacement
  • Uses R-22 refrigerant (phased out — refills are $$$)
  • Energy bills have been climbing year over year
  • Hot/cold spots in different rooms
  • Buying a new home without central AC
  • Major addition or remodel changed the load

How it works

Our process, step by step

  1. In-home assessment

    We measure your home, check ductwork, and run a Manual J load calculation. This determines the right tonnage — not a guess based on square footage.

  2. Equipment recommendations

    We present 3 options at different price/efficiency tiers. We tell you which one we'd put in our own house and why. No commission-driven pressure.

  3. Schedule and prep

    Most installs run 1 day. We protect floors, work clean, and haul the old unit away.

  4. Install and commission

    We pull a city permit, install per manufacturer spec, pressure-test refrigerant lines, and run a full commissioning test.

  5. Walkthrough

    We show you the new thermostat, schedule your first free maintenance visit, and register your warranty for you.

Common questions

FAQ

How long does an install take?
Most full replacements are a single day, 6–8 hours. Brand-new installs in homes without existing ductwork can take 2–3 days.
Should I go with a heat pump instead of AC + furnace?
Often yes — heat pumps now outperform gas furnaces in OC's climate and qualify for federal/state rebates that can cut 30–40% off the price. We'll lay out both options honestly.
What size system do I need?
It depends on insulation, windows, ductwork, ceiling height, and orientation — not just square footage. We run a Manual J calc so the system isn't oversized (short-cycles, humidity issues) or undersized (runs forever, can't keep up).
