Family Owned and in business serving homeowners since 1990
When your air conditioner starts acting up in the middle of a hot Mississippi summer, it's tempting to try and fix the issue yourself. Sometimes that’s okay but other times, it can lead to bigger problems, safety risks or even a voided warranty. At Tillman's Services, we believe in helping homeowners make smart, safe and cost-effective decisions. Here's how to tell the difference between what you can handle and when it's time to call in the pros.
For the handy homeowner, there are a few basic AC issues you can safely troubleshoot without professional help. These simple tasks can improve performance and potentially save you a service call:
Clogged filters can block airflow and cause your AC to work overtime. Replacing filters every 1–3 months is a quick and easy way to boost efficiency. If you have pets, consider changing them at least once per month.
If your system isn’t turning on or is blowing warm air, double-check that the thermostat is set to "cool" and that the temperature setting is below the room temperature.
Sometimes, the solution is as simple as flipping a tripped breaker. Just make sure you’re comfortable working around your home’s electrical panel.
Leaves, grass or even pet hair can block airflow to your outdoor condenser unit. Carefully clear away any buildup to keep things running smoothly.
While minor maintenance is safe for most homeowners, complex or persistent issues should be left to the experts. Here’s when to call an expert like Tillman’s:
Banging, screeching, hissing, or electrical smells can indicate serious issues like compressor damage, loose components, or refrigerant leaks.
If your AC keeps turning on and off or isn’t cooling the home effectively—even after filter changes—it’s time for a professional diagnosis.
Low refrigerant levels usually mean there’s a leak somewhere in the system. Handling refrigerants without certification is illegal and unsafe.
Digital display errors, wiring problems, or unresponsive thermostats require trained eyes and proper equipment to troubleshoot and repair.
If you smell gas, see sparks or suspect carbon monoxide buildup, shut off your system immediately and call us right away. These are not DIY jobs. Your safety comes first.
