What HVAC service are you looking for?

A complete HVAC system (furnace + AC) costs $7,000–$15,000 installed. AC only: $3,500–$7,500. Furnace only: $2,500–$6,500. Heat pump: $4,000–$8,000. High-efficiency and variable-speed systems cost more upfront but save 20–40% on energy bills annually.

Air conditioners: 15–20 years. Furnaces: 15–30 years. Heat pumps: 15–20 years. Proper maintenance (annual tune-ups, regular filter changes) is the single biggest factor in reaching the upper end of these ranges.

General rule: 1 ton of cooling per 500–600 sq ft. A 2,000 sq ft home typically needs a 3–4 ton system. But square footage alone isn’t enough — climate, insulation, ceiling height, window count, and ductwork all affect sizing.

The minimum federal standard is SEER2 15 for residential AC (as of 2023). SEER2 16–18 is a good value range. SEER2 20+ is premium/high-efficiency. Each SEER point above minimum saves roughly 5–7% on cooling costs. In hot climates, higher SEER pays back faster.

Generally no — the “$5,000 rule” helps decide: multiply the repair cost by the unit’s age. If the result exceeds $5,000, replace rather than repair. A 15-year-old unit needing a $400+ repair is usually better replaced with a modern, efficient system.
