Understanding Cowan’s Climate Challenges

Summer Heat and Humidity

• Prolonged high temperatures stress compressors and fan motors
• Elevated humidity levels challenge evaporator coils and encourage biological growth
• Voltage fluctuations during peak electrical demand can lead to short cycling

Transition Seasons

• Early spring pollen infiltrates air handlers, clogging filters
• Fall temperature swings demand quick changeovers between cooling and heating modes
• Off-season neglect often reveals hidden refrigerant leaks when systems restart

Winter Chill

• Sharp overnight freezing can affect heat pump defrost cycles
• Increased load on auxiliary heating elements raises energy bills
• Ductwork contraction and expansion cause air leakage and comfort imbalances

HEP’s service protocols account for each of these seasonal variables, ensuring that every inspection, repair, or installation addresses the specific stressors Cowan systems face.
