AC Replacement in Collierville, TN Homes
Call us about a worn-out central AC for a local HVAC company.
AC replacement in Collierville, TN means a new central split system of at least 14.3 SEER2 below 45,000 Btu/h, the DOE minimum for Tennessee. A local HVAC company sizes it by Manual J load and Manual S selection, and the Town requires a permit for the change-out. Ask for the Manual J cooling load when you call.
Who Calls About This
Collierville, TN owners call about AC replacement when a central system fails or no longer cools the home. Detached houses make up 80.9% of the Town's 19,054 housing units, per Census ACS data.
- Homeowners
- A failed compressor or an aging central system in one of the 15,413 detached houses inside the Town.
- Condo and townhome owners
- A new system for your own unit, which Tennessee condo law assigns to the owner unless the declaration says otherwise.
- Landlords who own houses or small rentals
- A rental house in Shelby County, where the Tennessee landlord act keeps premises fit and habitable. Renters leave a replacement decision to the landlord.
Inside a Standard AC Repair
Before suggesting a new system, the company diagnoses the old one, as covered under AC repair. A standard AC replacement then covers 8 steps from ACCA, DOE, EPA, and the Town.
Calculate the home's cooling load with ACCA Manual J.
Select equipment with ACCA Manual S, based on that load.
Confirm the outdoor unit and indoor coil combination meets 14.3 SEER2 below 45,000 Btu/h, or 13.8 SEER2 at 45,000 Btu/h and up.
Confirm the refrigerant sits below EPA's 700 GWP limit, or that all specified components were made or imported before January 1, 2025.
Charge a TXV system by subcooling to the value on the unit's nameplate.
Route the condensate to an indirect waste within 2 feet or an approved French drain, per the Town's amendment.
Pull the Town of Collierville mechanical permit and request its inspection.
Explain the warranty registration window, 90 days for one manufacturer's 10-year AC term.
Ductwork changes, electrical upgrades, and a matching furnace replacement fall outside a standard AC replacement. Before you call, we recommend noting whether the furnace is as old as the AC.
Ask for the Manual J cooling load and the SEER2 of the system on the quote.
(901) 613-0388Local AC Issues and What Your HVAC Company Does
Collierville AC replacement situations fall into 5 cases, each paired below with the step the HVAC company takes.
| What you notice | What your HVAC company does |
|---|---|
| The compressor fails on an older R-410A system | EPA allows a new condensing unit on an existing system and does not count it as a new installation. The company explains that path beside a full replacement. |
| The home sits in new development or redevelopment | The Town's 2024 design guidelines hide ground-mounted AC units from public view. The company plans the unit's spot and screening to fit them. We add one caveat: the ordinance covers new development and redevelopment only. |
| The home sits in the Collierville Historic District | The district's guidelines place exterior mechanical units at the side or rear, screened. A local HVAC company sets the new outdoor unit in one of those spots. |
| The home gained an addition after the old AC went in | The company runs a new Manual J load calculation, since the 2018 IRC sizes equipment on Manual J loads. |
| The permit goes in on or after January 1, 2027 | New plans and permits from that date follow the 2024 International codes in Collierville. The company designs to that edition. |
Steps From the First Call
Your AC replacement follows 5 steps from the first call to the startup check.
- 1
Call and describe the current system
You call us with the system's age, its refrigerant when known, and what failed. We get a local heating and cooling company on the line, and those details shape its first visit.
- 2
Let the company run the load calculation
The HVAC company measures the home for an ACCA Manual J calculation and diagnoses the old system. Ask for a written estimate before work starts.
- 3
Choose equipment that meets the SEER2 minimum
You pick from equipment selected by Manual S, each at 14.3 SEER2 or higher below 45,000 Btu/h.
- 4
Pull the permit and request the inspection
Town rules require a licensed contractor to pull the permit. The permit holder then requests the inspection by phone, email, or iWorQ.
- 5
Check the startup charge
The company charges a TXV system by subcooling to the nameplate value and shows you the reading.
What Changes the Price of AC Replacement
AC replacement prices in Collierville, TN depend on 5 factors measured at the home, and no government or trade source publishes a local price. The NOAA station we use logs 63.4 days a year at or above 90°F here. That cooling load, run through Manual J, sets the size you pay for.
Factor 1
System Size
ACCA Manual J sets the cooling load, and Manual S selects equipment to match it. The system size that the load supports sets the equipment price.
Factor 2
SEER2 Class
The DOE efficiency standard for Tennessee is 14.3 SEER2 below 45,000 Btu/h and 13.8 SEER2 at 45,000 Btu/h and up. A higher SEER2 class you ask about prices above that floor.
Factor 3
Refrigerant Path
New systems use a refrigerant below 700 GWP from January 1, 2025, per EPA. A 2026 EPA rule still lets a split system built from pre-2025 components go in, so ask which path a proposed system follows.
Factor 4
Outdoor Unit Placement
Historic district guidelines and the Town's 2024 design guidelines govern where a ground-mounted unit sits and how it is screened. Placement and screening add to the price.
Factor 5
Permit and Code Edition
A mechanical change-out needs a Town of Collierville permit, and work begun before it doubles the fee. Permits filed from January 1, 2027 follow the 2024 International codes.
Ask who pulls the Town permit for your AC change-out and which refrigerant the new system uses.
(901) 613-0388Codes and Permits That Apply in Collierville
Codes and permits in Collierville, TN require a permit for a mechanical change-out and a state or county licensed contractor for all mechanical work. The person who obtained the permit requests the inspection by phone, email, or the Town's iWorQ portal.
Collierville enforces the 2018 IRC, whose section M1401.3 sizes equipment by ACCA Manual S on Manual J loads. From January 1, 2027, new plans and permits follow the 2024 International codes, the 2021 IECC, and the 2023 NEC. Plans drawn in late 2026 can land under either edition, so we tell callers to ask which one applies on their permit date.
EPA limits new residential AC systems to refrigerants below 700 GWP from January 1, 2025. A 2026 EPA rule, effective July 27, 2026, lets split systems built from pre-2025 components still be installed. You can ask which rule the proposed system follows.
Coverage and Rebate Questions
No federal 25C credit applies to an AC replaced in 2026, since the IRS bars it for property placed in service after December 31, 2025. MLGW, the electric utility here, lists no utility rebate of its own for AC. Ask about the manufacturer's warranty on the new system, and see furnace and AC questions for coverage topics.
An HO-3 homeowners policy excludes wear and tear and mechanical breakdown, per the Insurance Information Institute's sample form. Ask your insurer what covers a failed AC. MLGW's Share the Pennies grants for low-income Shelby County homeowners list HVAC replacement among eligible repairs.
What SEER2 Level Does a New AC Need in Tennessee?
A new split AC in Tennessee needs at least 14.3 SEER2 below 45,000 Btu/h and 13.8 SEER2 at 45,000 Btu/h and up. That DOE Southeast standard covers installations since January 1, 2023, and DOE enforces it at installation. The HVAC company confirms the outdoor unit and coil combination meets it, so ask for your combination's SEER2.
What Size Central AC Does Your Home Need?
Your home's central AC size comes from an ACCA Manual J load calculation, and ACCA Manual S selects the equipment for that load. The 2018 IRC, which Collierville enforces, requires that method or another approved one. Ask for the cooling load in Btu/h and the tonnage it supports, and mention any addition or new windows, since both change that number.
Collierville Details That Change the Repair
- A county-line home in Eads, TN answers to Memphis and Shelby County Code Enforcement on the Shelby side and Fayette County on the other. Check which county holds the parcel, and call the Fayette County office to confirm its HVAC permit rules.
- The Town's July 22, 2024 design guidelines hide ground-mounted AC units from public view in new development and redevelopment. Ask where the new unit sits before you approve the plan.
- The NOAA Collierville station logs 63.4 days a year at or above 90°F and 1,899.2 cooling degree days. Heating degree days reach 3,292.7 at the same station.

Questions Before You Call
Open any question below for its answer
Is It Better to Repair or Replace an Aging Central AC?
The choice depends on the failed part, since EPA lets an R-410A system be repaired, including a new condensing unit or compressor. A full replacement meets 14.3 SEER2 below 45,000 Btu/h in Tennessee and needs a Town permit. Ask the company to price both options side by side.
Is There a Federal Tax Credit for a New AC in 2026?
No. A central AC placed in service in 2026 falls after that credit's December 31, 2025 end date, per the IRS. Ask about warranty registration on the new system.
Does an AC Replacement Need a Permit in Collierville?
Yes, the Town of Collierville requires a permit for a mechanical change-out, and its rules require a licensed contractor to pull it. Starting the swap before the permit is issued doubles the Town's fee. Ask who requests the inspection after the work.
Can a New AC Still Use R-410A in 2026?
Yes, a split system with R-410A can still go in when all its specified components were made or imported before 2025, per EPA. Other new systems use refrigerants below 700 GWP. Ask which refrigerant the proposed system uses.
Why Register a New AC in Its First 90 Days?
Registration sets the warranty term: one manufacturer's AC warranty runs 10 years when registered in the first 90 days, otherwise 5. That warranty excludes labor, so the FTC's advice to check who pays for labor applies. Ask the HVAC company whether it registers the unit or leaves that to you.
