Heating & Furnace Installation in Mt. Juliet, TN

A new furnace or heat pump is a long-term decision for your home. Childs Heating & Air provides residential and light-commercial heating installation and furnace installation in Mt. Juliet and nearby Middle Tennessee communities from our shop at 5011 Market Place, Unit B. Childs Heating & Air was founded in 2008 by Justin Childs, with roots back to 1976 through Jim Davis Heating & Air.

We size and install gas furnaces, electric furnaces, air-source heat pumps, hybrid setups when that match fits the home, and ductless options when a space needs heat without new duct runs. Before any equipment is ordered, we walk you through what fits your house, your ducts, your fuel type, and your budget — in plain language, not sales jargon.

Childs Heating & Air is licensed, bonded, and insured. Regular hours are Monday through Friday, 8 a.m. to 5 p.m. For after-hours heating failures while you wait on a replacement decision, 24/7 emergency service is available by phone. Call (615) 519-8545.

Why right-sized heating installation matters

Middle Tennessee winters bring cold snaps that push heating systems hard. An undersized furnace or heat pump runs almost nonstop and still leaves cold rooms. An oversized system short-cycles, wears parts faster, and can leave some spaces uncomfortable. Homes across Mt. Juliet, Hermitage, Old Hickory, Lebanon, Nashville, and nearby towns also vary widely in insulation, duct condition, and how open the floor plan is — so matching the old unit’s label alone rarely works well.

We start with a careful look at your home’s heating needs: square footage, insulation, existing ductwork, fuel type (gas or electric), and how you use the space. That load-based approach is the foundation of a system that stays comfortable on cold mornings without unnecessary runtime.

Heating systems we install

• Gas and electric furnaces for whole-home heat through existing or updated ductwork
• Heat pump systems that heat in winter and cool in summer from one outdoor unit — see our heat pumps page for repair and installation details
• Hybrid setups that pair a heat pump with a furnace when that combination fits the home and how you use it
• Ductless mini-splits for additions, bonus rooms, or homes where ducts are impractical — see ductless HVAC

We service and install equipment across makes and models. We do not push a single brand. The right choice is the one that matches the house, the ducts, and the way your family lives.

What to expect on a heating installation project

1. On-site evaluation of the home, existing equipment, fuel and electrical capacity, and duct condition.
2. Clear proposal with system options sized for the building, not a guess based on the old unit’s label alone.
3. Remove and replace the furnace, air handler, and/or outdoor unit as scoped, and connect fuel, refrigerant or flue paths, drainage, and controls as scoped and to applicable code.
4. Start-up and check — confirm the system heats and cycles correctly, and that the thermostat operates as expected before we leave.
5. Walk-through so you know how to run the system, change filters, and spot issues early.

If duct repairs or sealing would improve comfort, we say so up front so you can compare options before work begins. Free estimates are available for new installs and replacements.

Repair, replace, or wait?

Not every cold house needs a brand-new system tomorrow. If your current furnace or heat pump can be repaired safely and economically, we will say so and show you the option. When the equipment is near the end of its life, needs repeated major repairs, or can no longer keep up with the home, we explain replacement options as the more practical path and provide an estimate so you can compare.

For breakdowns and fixes that are not a full replacement yet, see heating repair. For Mt. Juliet-specific repair help, see heating repair in Mt. Juliet. For ongoing tune-ups after install, see heating service.

Every repair comes with at least a 30-day parts-and-labor warranty, and many jobs carry longer coverage of up to 2 years or more, as listed on your invoice. Refrigerant is not covered.
