What this guide covers
Homeowners across Mt. Juliet, Nashville, Lebanon, Hermitage, and nearby communities ask the same question every summer: what will cooling repairs or a replacement actually cost? This guide explains the factors that drive price in Middle Tennessee. Childs Heating & Air provides clear recommendations after diagnosis and free replacement estimates — we do not publish one-size online prices or invented averages.
Serving Middle Tennessee since 1976 through roots in Jim Davis Heating & Air; Childs Heating & Air was founded in 2008.
What drives AC repair costs
- The diagnostic visit. Repair visits start with a $79 diagnostic service call, which is waived if you go ahead with the repair.
- The failed part and labor time. A run capacitor differs from a compressor, coil, or blower repair in both parts and time on site.
- System age and accessibility. Attic air handlers, tight closets, and older equipment can add complexity.
- Time of service. 24/7 emergency service is available by phone; after-hours and emergency charges may apply.
- Refrigerant type and leak-related work. Leak find-and-fix is evaluated case by case and must follow applicable rules.
- Whether the visit includes related airflow fixes. Filters, drain clearing, and blower cleaning sometimes travel with the main repair.
Repair visits start with a $79 diagnostic service call, which is waived if you go ahead with the repair. Free second opinions are available. Military members can ask about $25 off repair (code SALUTE). Start with AC repair if you already know you need service.
What drives replacement costs
- Correct sizing for the home — not simply matching the old unit’s label
- Efficiency level and equipment choices
- Duct condition and any needed modifications for airflow and comfort
- Installation complexity (line set, pad, disconnects within HVAC scope, permits as required)
- Indoor comfort goals such as humidity control or zoning discussions during design

Why maintenance changes the math
Seasonal maintenance will not prevent every failure, but it helps catch airflow problems, dirty coils, and worn components before a holiday weekend breakdown. That often means fewer emergency after-hours visits — and after-hours charges may apply when emergencies do happen. Explore maintenance plans. Between professional visits, change disposable filters on a schedule that matches pets, allergies, and runtime.

Repair vs. replace — questions to ask
- How old is the system, and how often has it needed repair recently?
- Is the recommended repair a durable fix or likely to recur soon?
- What efficiency and comfort improvements would a replacement bring for this specific home?
- For a replacement estimate, what is included — and what conditions would change the total?
- What warranty comes with this repair, and how long does it last?
