What Is The $5000 Rule For HVAC And How Does It Affect Costs?

The “$5,000 rule” is a rule of thumb people use to weigh repair vs. replacement, but the right decision depends on your system and an on-site inspection. We perform full diagnostics, provide upfront prices, and explain options before work starts. Many repairs are completed the same day with our well‑stocked trucks. Maintenance plan members get priority scheduling and discounts. Ask about our current offer: a free service call with any paid repair, valid through 2025-12-31. We provide 24/7 service in Glendale Heights, St. Charles, and nearby.
