AC Installation vs AC Replacement: What's the Difference?
New System, New Design
AC installation puts cooling where there wasn't any, so it often needs new ductwork, new electrical and a new equipment location. AC replacement swaps an existing system and reuses most of what's already there.
| Job | AC Installation | AC Replacement |
|---|---|---|
| Existing system | None, or none in that space | Yes, old system removed |
| Ductwork | Designed and installed new | Reused if sound, repaired if not |
| Electrical | New circuit, disconnect and whip | Usually reused or updated |
| Typical price | $5,500-$15,000+ | $4,500-$13,500+ |
| Timeline | 2 to 4 days | 1 to 2 days |

Types of AC Installation Right Away Heating and Air Handles
Four Common Projects
AC installation from Right Away Heating and Air covers four common projects: new construction, room additions, homes adding central air, and rooms the main system can't reach.
New Construction AC Installation
New construction AC installation works best when we're involved before the drywall goes up, so ducts, returns and the equipment closet are planned right.
Home Additions and Garage Conversions
Home additions and garage conversions often overload the existing system. We check whether your current AC can carry the new space or whether a separate system or mini split makes more sense.
Older Homes Adding Central Air
Older homes adding central air, like some mid-century ranches, need new ducts run through the attic or crawl space, plus a new circuit and returns.
Bonus Rooms and Sunrooms
Bonus rooms over the garage and sunrooms are often the hottest rooms in the house. A ductless mini split usually cools them better than stretching the main system.

What Drives the Price of a New AC Installation?
The price of a new AC installation depends mostly on ductwork and electrical, not just the equipment.
- How many rooms need supply ducts and returns.
- Whether the attic or crawl space is easy to work in.
- Whether your electrical panel has room for a new circuit.
- The size and efficiency of the equipment.
- Whether the home is on the coast and needs a raised stand or coated coil.

How We Design and Install a New AC System
Sized, Ducted, Tested
A new AC system from Right Away Heating and Air starts with a load calculation and a duct design, then gets installed, tested and commissioned before we hand you the thermostat.
- Walkthrough. We measure rooms, windows, insulation and the attic or crawl space.
- Load calculation. We figure the cooling and heating each room needs.
- Duct design. We size trunks, branches and returns for quiet, even airflow.
- Written quote. Equipment, ducts, electrical and permit, all itemized.
- Install. Equipment set, ducts run and sealed, line set brazed under nitrogen.
- Test and commission. Pressure test, deep vacuum, charge, airflow and temperature split.
- Walkthrough and registration. We show you the system and register the warranty.
Why Does Duct Design Matter on a New Install?
Duct design matters on a new install because the best AC in the world can't cool a room it can't push air into. Poor duct design shows up fast.
| Duct Problem | What You Feel |
|---|---|
| Undersized supply runs | Hot back bedrooms |
| Too few returns | Noisy vents and doors that slam |
| Unsealed joints | High bills and humid air |
| Long, kinked flex ducts | Weak airflow at the end of the run |
