HVAC Company in Lebanon, TN
Dalton Heating & Air handles HVAC work across Lebanon, TN, from furnace repair in older ranch homes off West Main Street to heat pump installation in newer subdivisions near Interstate 40. Our crews live with the same conditions you do: humid summers that push air conditioners hard, winters that dip low enough to freeze unprotected lines, and a housing mix that spans 1970s builds to homes finished this year. Call (361) 306-9515 when you need a straight answer on what the job costs and who is showing up.
Why Lebanon Homes Are Different
Lebanon sits in a climate band where HVAC systems earn their keep almost year-round. Summer humidity regularly drives heat indexes past 100°F, which means an undersized or aging AC unit fails at the worst possible time. Winter temperatures routinely fall into the 20s, and while deep freezes are less common than points north, they happen often enough that a failed furnace is a genuine risk, not an inconvenience. Homes here reflect the city’s growth pattern: smaller 1960s and 1970s brick ranches near the square, larger 1990s and 2000s colonials on the north and west sides, and new construction pushing toward the Wilson County line. Each era presents different duct layouts, electrical capacity, and insulation profiles. Older homes commonly have metal ductwork that leaks at the seams, while newer builds sometimes arrive with builder-grade equipment that is already out of warranty. Terrain matters, too: homes on the rolling lots west of Highway 231 often need condensers placed and leveled differently than flat-lot homes in the city center. Some neighborhoods with HOA covenants require specific condenser placement or screening, and we check that before installation. Scheduling in Lebanon also accounts for traffic along Highway 109 and the Interstate 40 corridor during peak hours, which affects how we route technicians.
Our Main Lebanon Services
Most Lebanon homeowners call us for three things: an AC system that is not cooling in the middle of a humid summer, a furnace that will not light when the temperature drops, and a heat pump installation to replace equipment that has reached the end of its life. Each service has its own Lebanon page with detailed pricing and timelines.
AC Repair in Lebanon
Air conditioning in Lebanon runs hard from late May through September, and the most common failure we see is a system that has lost refrigerant charge. That means a leak somewhere in the line set, and it needs to be found and fixed before recharging, not just topped off and forgotten. In Lebanon’s humidity, a low-charge system also freezes the evaporator coil, which restricts airflow and can damage the compressor if ignored. We diagnose first, put the repair price in writing, and complete most fixes the same visit. AC Repair in Lebanon covers costs, common failures, and our repair guarantee in detail.

Heat Pump Installation in Lebanon
Heat pumps work well in Lebanon because they handle both cooling and heating in one unit, and the winter lows rarely fall below a modern pump’s efficient operating range. The key to a good installation in this area is sizing: an oversized heat pump short-cycles in humid weather and leaves the home clammy, while an undersized one cannot hold temperature in January. We run a load calculation on every install, not a rule-of-thumb square-footage guess. Heat Pump Installation in Lebanon walks through equipment options, installation timelines, and written pricing.

Furnace Repair in Lebanon
Furnaces in Lebanon homes range from 30-year-old gas units in established neighborhoods to high-efficiency systems installed with newer construction. Common failures here include ignitors that have burned out, limit switches that trip due to restricted airflow, and heat exchangers that have developed cracks in older units. When a furnace stops heating on a January night in Lebanon, waiting a day for a callback is not acceptable, which is why our phone line is answered by a live person 24 hours a day. Furnace Repair in Lebanon details repair costs, safety checks, and our one-year written guarantee.

FAQs About HVAC Company in Lebanon
For most repair calls inside Lebanon city limits, we can have a technician at your door the same day. Emergency no-heat and no-cooling calls get priority, and our phone line is answered by a live person 24 hours a day, seven days a week. Call (361) 306-9515 and we will give you a straight answer on timing.
Most full system replacements in Lebanon require a mechanical permit through Wilson County. We handle the permit paperwork on installations, so you do not have to sort that out yourself. Repairs and replacements of single components, like a capacitor or a thermostat, do not typically require a permit.
Some Lebanon neighborhoods with homeowner associations have covenants that govern where an outdoor condenser can sit, how it is screened, or what noise level is acceptable. Before we install, we check what applies to your lot and size the placement accordingly. That way the job passes compliance the first time instead of triggering a notice from the board.
