We start with a load calculation and a look at your ductwork, drainage, and electrical service, then give you a written estimate that shows exactly what's included — no vague equipment number.
Signs it's time to replace, not repair
- Repairs are recurring and adding up
- The system is 12–15+ years old and losing efficiency
- Rooms stay humid even when the temperature is fine
- The compressor or coil is failing or badly corroded
- Energy bills climb every summer
- R-22 refrigerant makes repairs expensive
What affects your price
Figures below are published local benchmarks and non-binding estimates — never a quote. You'll get every charge in writing first.
- Published Covington AC replacement benchmark $3,000–$9,000; broader central AC $3,400–$7,200
- System capacity and SEER2 efficiency level
- Duct modifications, sealing, and drainage corrections
- Elevated pad or flood-smart placement
- Financing terms — compare total financed cost, not just the monthly payment
What's included with ac installation in Covington
Every ac installation job is scoped and documented up front — here's what you get when we roll up to your Northshore home or business.
- Manual J-style load calculation so the new system is sized to your actual house, not a rule of thumb
- High-SEER2 equipment selection meeting DOE Southeast minimums (14.3 under 45k Btu/h, 13.8 at or above)
- Matched coil and air handler pairing for real efficiency and humidity removal
- Removal and responsible disposal of the old condenser and coil
- New line set, whip, disconnect, and pad or elevated stand as the site requires
- Full commissioning with charge, airflow, and static pressure set to spec
- Walkthrough of thermostat, filters, and warranty registration documents
Sized and tested for the Gulf Coast
SEER2 is the current seasonal efficiency rating for covered equipment. For split systems installed since January 1, 2023, the Department of Energy's Southeast-region minimums are 14.3 SEER2 below 45,000 Btu/h and 13.8 SEER2 at or above that capacity. We'll confirm the equipment category, capacity, and efficiency that actually fit your home.
A larger system is not automatically better here. Incorrect sizing reduces runtime and moisture removal, which leaves your home clammy. We commission every install — verifying temperature split, airflow, drainage, and refrigerant charge — so the system performs the way the estimate promised.
What a real replacement estimate shows
Ask for at least two written estimates when time and safety allow, and compare them line by line rather than by a single price. A complete estimate covers equipment model and capacity, SEER2, load basis, duct modifications, pad and drainage, electrical work, thermostat, permits, removal, startup testing, registration, and both workmanship and manufacturer warranties.
- Equipment model, capacity, and SEER2 rating
- Load calculation / sizing basis
- Duct modifications, sealing, and condensate drainage
- Pad, elevation, and corrosion considerations
- Permits, startup testing, and commissioning
- Workmanship and manufacturer warranty terms
- Total installed price and total financed cost
Our ac installation process
Test first, document everything, and get your sign-off before the work happens — no guesswork, no surprises.
- 1
Size it correctly
We run a load calculation on your home's square footage, insulation, and windows so the system dehumidifies instead of short-cycling.
- 2
Match the equipment
We recommend a right-sized, high-SEER2 system suited to Covington's long, humid cooling season and your budget.
- 3
Set the estimate
You get a clear scope and a benchmark replacement range, generally $3,000-9,000, before scheduling.
- 4
Install clean
We pull the old unit, run new line set and electrical, and mount the condenser to survive our rain and water table.
- 5
Commission and verify
We charge to spec, set airflow, measure the temperature split, and confirm humidity control before handing it over.
