How much does HVAC replacement cost?
A complete HVAC replacement (central AC + furnace) typically costs $6,000–$14,000 installed. AC-only replacement runs $3,500–$7,500. Prices depend on system size (tonnage), SEER rating, brand, and installation complexity.
How often should HVAC be serviced?
HVAC systems should be serviced once a year — ideally in spring for cooling season and fall for heating. Annual maintenance costs $75–$200 and extends system life, catches problems early, and maintains manufacturer warranties.
What SEER rating should I buy?
SEER (Seasonal Energy Efficiency Ratio) measures cooling efficiency. Higher SEER = more efficient but more expensive upfront. Minimum federal standard is 14–15 SEER depending on climate zone. 16–18 SEER is a good balance of cost and savings. 20+ SEER is premium and pays back slowest.
How do I compare HVAC quotes?
Compare brand and model number, SEER/HSPF ratings, tonnage (system size), warranty terms, labor warranty, and whether duct inspection/modification is included. A cheap quote that skips proper load calculation or duct evaluation will cost you more long-term.
