Residential AC Repair Services

When your air conditioner fails, it's more than an inconvenience—it disrupts your comfort and can affect your indoor air quality. Our team at KMI A/C and Heating offers dependable AC repair services to get your system back on track quickly and efficiently.

Signs You Need AC Repair:

• Warm air coming from vents instead of cool air, even when the thermostat is set correctly.
• Unusual noises such as rattling, grinding, or buzzing, which may indicate loose parts, failing motors, or fan issues.
• Unpleasant odors from the air conditioning unit, often caused by mold growth or burnt wires.
• Frequent cycling or failure to maintain set temperature, which stresses the HVAC system and reduces comfort.
• Increased utility bills with no change in usage, usually due to reduced system efficiency or hidden malfunctions.

Common AC Issues We Handle:

• Refrigerant leaks and low refrigerant levels leading to weak airflow and poor cooling performance.
• Faulty thermostats or electrical control issues that prevent your AC system from responding properly.
• Clogged or dirty air filters and condenser coils that restrict airflow and overwork the system.
• Frozen or malfunctioning evaporator coils, which can shut down cooling operations entirely.
• Damaged compressors or fan motors, often the result of neglect or aging systems.
