Frequently Asked Questions About HVAC Costs
Is it cheaper to repair or replace my HVAC system?
The rule of thumb: if the repair cost exceeds 50% of the replacement cost, or if the system is more than 10-15 years old, replacement is usually the better investment. Newer systems are 30-50% more energy efficient.
What size HVAC system do I need for my Boise home?
Proper sizing depends on square footage, insulation, windows, and local climate. Most Boise homes (1,500-2,500 sq ft) need a 2-3 ton AC unit. Our licensed technicians perform load calculations to ensure proper sizing.
