Frequently Asked Questions
How long does an HVAC system last?
Most central AC systems last 15–20 years with proper maintenance. Furnaces typically last 20–30 years. If your system is approaching these ages and requiring frequent repairs, replacement is usually more cost-effective.
What size HVAC system do I need?
System sizing depends on your home's square footage, insulation, windows, and local climate. A licensed HVAC contractor should perform a Manual J load calculation — never accept a replacement based on matching the old system size alone.
Should I repair or replace my HVAC system?
If repair cost exceeds 50% of replacement cost and the system is over 10 years old, replacement is usually the better investment. Newer systems are significantly more energy-efficient, reducing monthly utility costs.
