Regular maintenance is the most effective way to prevent AC breakdowns during peak cooling season. This includes changing filters monthly during heavy use, keeping outdoor units clear of debris and vegetation, and scheduling professional tune-ups before summer heat arrives. Our Dempsey Comfort Club provides systematic maintenance that catches small problems before they become expensive emergency repairs. During maintenance visits, our technicians clean coils, check refrigerant levels, test electrical connections, and inspect components for wear. We’ll also identify potential issues and recommend addressing them during off-peak seasons when parts are readily available and scheduling is more flexible. Simple homeowner maintenance combined with professional service significantly reduces the likelihood of AC failures when you need cooling most.
