Frequently Asked Questions
A new HVAC system typically costs $5,000-$15,000 including installation. Central AC units run $3,000-$7,000, furnaces $2,500-$6,000, and heat pumps $4,000-$10,000. High-efficiency models cost more but save on energy bills.
Schedule professional maintenance twice yearly - once for heating (fall) and once for cooling (spring). Regular service extends equipment life, maintains efficiency, and catches problems early.
Consider replacement if your system is 15-20+ years old, needs frequent repairs, has R-22 refrigerant (phased out), can't maintain comfortable temperatures, or your energy bills are increasing despite maintenance.
Minimum SEER is 14-15 (varies by region). SEER 16-20 offers good efficiency, while 21+ is high-efficiency. Higher SEER costs more upfront but saves money over time. Consider your climate and usage when deciding.
Improve efficiency by: changing filters monthly, sealing duct leaks, adding insulation, using a programmable thermostat, keeping vents unblocked, and scheduling annual maintenance.
The "5,000 rule" helps decide: multiply the repair cost by the unit's age. If the result exceeds $5,000, replacement is usually better. Also consider refrigerant type, efficiency, and whether repairs are becoming frequent.
