The average cost to install central air varies by home and system, and Homestead Heating & Air provides a firm price only after an in-home evaluation and cooling load calculation. The biggest drivers are home size and the efficiency and capacity of the Lennox equipment you choose, and financing is available starting as low as $79/month.
Our team serves the Rowlett area with right-sized designs to match your home’s actual load, not a guess. A properly sized system often avoids costly duct changes that an oversized unit would need. If your current unit is failing repeatedly, replacement tends to be the smarter spend; if issues are minor, a repair may be enough.
Typical line items that affect final price:
- Equipment size and efficiency rating selected
- Existing duct condition, sealing needs, or layout changes
- Refrigerant line, drain, pad, or electrical upgrades
- Add-ons like smart thermostat, indoor air quality, or attic insulation
