When a Repair Becomes a Permitted Change-Out
A repair becomes permit work in Collierville once it turns into a change-out. The Town exempts normal maintenance and repairs from a permit, but its rules require a licensed contractor to pull one for a mechanical change-out.
On the call, the HVAC company tells you which side of that line your job falls on. The 6 price factors for either side, from the failed part to the Town permit fee, sit on the furnace repair cost page.
How the Seasons Split Heating and Cooling Work
The Collierville weather station logs 3,292.7 heating degree days and 1,899.2 cooling degree days in a normal year, so you run both systems hard. December through February holds about 63% of the heating load.
A yearly visit keeps both sides in check, and the furnace maintenance page lists what the manufacturer's manual asks for. For a worn-out condenser, our AC replacement page sets out the Southeast SEER2 minimums.
Rebates and Credits Checked for 2026
No federal 25C tax credit applies to a furnace or central AC placed in service after December 31, 2025, per the IRS. MLGW lists no furnace or AC rebate of its own.
Low-income Shelby County homeowners can apply for MLGW's Share the Pennies grants, which can cover HVAC repair or replacement. The furnace and AC questions page groups the other coverage answers by topic.
Name your system and what it is doing, then ask the HVAC company whether the job counts as a repair or a Town change-out.
