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

The $5,000 rule is a general rule-of-thumb for repair vs replace, but we recommend a technician diagnostic instead. We price after inspecting the fault, parts and labor, system age, warranty coverage, and efficiency gains. Lower repair costs with our $150 off HVAC repair coupon and maintenance-plan discounts. If replacement is smarter, we process Mass Save incentives: instant rebates up to $16,000 and 0% HEAT Loan options. In-house technicians and manufacturer warranties up to 12 years help control lifetime costs in Boston.
