The core of any HVAC system is its parts. The cost of the parts varies from insulated copper line sets, packaged units, factory boxes, or a safe delivery system. Know what parts your system uses, and budget for replacements based on age and use. A good rule of thumb is to budget a little extra in case anything unexpected happens.
