A sizing mistake costs more than a price mistake: an undersized unit keeps the enclosure hot all summer and component failure rates climb. HCK sees the same four mistakes in project reviews — worth checking before purchase.
Mistake 1: reading nameplate capacity only
Nameplate ratings assume standard conditions. When site ambient runs above the standard point, usable capacity drops and selection must be corrected for real duty.
Mistake 2: sizing heat from device nameplates
Actual heat depends on load factor and efficiency; drive and power-supply losses are usually underestimated. Sum measured data or manufacturer loss figures instead.
Mistake 3: comparing purchase price only
Energy, filter replacement, downtime and support response all belong in total cost. Cheap units often give the savings back in peak-season repairs.
Mistake 4: leaving no installation or service space
Blocked inlet/outlet openings and filters that cannot be pulled cut real performance. Check clearances against the drawing before installing.
