Why HVAC Short Cycling Happens in St. Petersburg

In St. Petersburg, HVAC short cycling can be particularly prevalent due to the unique climate and environmental factors. The proximity to Tampa Bay and the Gulf of Mexico introduces significant salt air, which can corrode HVAC components more quickly than in inland areas. Many homes in the area, especially older constructions, may have oversized HVAC systems that are ill-suited for their square footage. Additionally, the humid climate can lead to dirty air filters and frozen evaporator coils, further exacerbating short cycling issues. Local weather patterns may also cause thermostats to be placed in less-than-ideal locations, such as drafty or sunny spots, affecting their accuracy and performance.
