Gunniss and Marsh Air Conditioning and Heating Svc - Cantonment's Certified HVAC Services

The constant, heavy operation of air conditioners in our Florida heat puts significant stress on electrical components. Capacitors, which help start and run the compressor and fan motors, are particularly vulnerable to wear from high temperatures and power surges. At Gunniss and Marsh, our preventative maintenance checks capacitor health specifically to catch early signs of failure, like bulging or leaking, before your system breaks down on the hottest day.

Start with regular HVAC maintenance, including changing your air filter every 1-3 months. For Cantonment's humid climate and pollen, we often recommend upgrading to a higher MERV-rated filter, adding a UV light system to combat mold and bacteria, or installing a whole-home dehumidifier. Our team can assess your specific needs and home layout to recommend the most effective and efficient solution for cleaner, healthier air.

Listen for a humming sound from your outdoor unit, notice your AC struggling to start (it may trip the breaker), or see your system shutting off unexpectedly. You might also feel weak airflow from your vents. If you experience any of these issues, it's time to call us. We carry a wide range of capacitors on our service trucks for most Cantonment-area systems, allowing for same-day repairs to restore your cooling quickly and safely.
