Experienced HVAC Repair in Lilburn, GA 30047 - Cohran Mechanical Services

This is a common issue, especially when systems are overworked. First, check your thermostat settings and air filter. If those are fine, it could be a refrigerant leak, a failing compressor, or a frozen coil. To prevent further damage, turn the system off and call us. Our 24/7 emergency team can diagnose and repair the problem quickly, often the same day, to restore your cooling and protect your system from a complete breakdown.

Our thorough maintenance service is designed to keep your system running efficiently and catch small issues before they become big problems. We inspect electrical connections, check refrigerant levels, clean coils, lubricate moving parts, test system controls, and ensure your thermostat is calibrated. For Lilburn homeowners, this proactive care is key to preventing mid-summer breakdowns and helps maintain better energy efficiency year-round.

It depends on the age, efficiency, and cost of repairs for your current system. If your unit is over 10-15 years old, requires frequent repairs, or your energy bills are climbing, a replacement may be the more cost-effective choice. We provide a detailed assessment and estimate for both options, explaining the benefits of newer, more efficient models that can improve comfort and reduce monthly costs, all backed by our labor warranty.
