Grandmark Service Company Madera: Certified HVAC Repair Serving Madera, CA 93638

Short cycling, where your system turns on and off too frequently, is often caused by an oversized unit or refrigerant issues and wastes energy. Our technicians perform a thorough diagnostic to pinpoint the exact cause—checking sizing, refrigerant levels, and thermostat settings. We then provide a clear repair plan or, if needed, discuss properly sized replacement options that run more efficiently in our local climate, helping to improve comfort and reduce wear on your system.

Our comprehensive roof inspection includes checking for damaged or missing shingles, examining flashings around vents and chimneys, assessing the condition of gutters and downspouts, and looking for signs of water intrusion or sagging in the attic. As Energy Experts, we also evaluate your roof's suitability for solar installation or insulation upgrades. You'll receive a detailed report with photos and our professional recommendations for any necessary repairs or maintenance to protect your home.

Regular maintenance is key to system longevity, efficiency, and preventing costly breakdowns, especially during our hot summers. Our maintenance service includes cleaning coils and components, checking refrigerant levels, calibrating thermostats, and inspecting electrical connections. This proactive care helps maintain steady airflow, improves indoor air quality, and ensures your system runs as efficiently as possible, which can lead to significant energy savings over time.
