Did your air conditioner suddenly stop? If you're not sure what to do next, take a look at the do's and don'ts of AC repair. 

Do Call a Repair Contractor

Air conditioning repair is not a do-it-yourself job. While a DIY approach may seem like the most cost-effective option, it could cause additional damage. This could result in the need for additional (and pricey) repairs. Beyond the potential for extra costs, a DIY repair could pose a serious safety hazard. 

If your AC system stops suddenly on a hot, humid day, you may need to find an emergency repair contractor. This type of HVAC professional offers evening, night-time, and weekend services. Before you agree to an emergency repair, ask the contractor if there is an extra charge or higher fee for an after-hours appointment. Even though you may need to pay more for an emergency repair, this option is ideal when the weather is uncomfortably hot or you have safety concerns.

Don't Forget About the Power Source

Air conditioners require electricity to effectively cool the indoor air. Without power, your home's system won't turn on or push cool air into each room. Even though you shouldn't attempt a DIY repair, you can check the circuit breaker or fuse box for power source issues. A tripped breaker or blown fuse could stop the system. 

Do Check the Thermostat

It's likely you didn't change the thermostat's settings. But did someone else in your household turn the temperature up? A higher temperature setting will stop the air conditioner from turning on. If you aren't aware of a thermostat change or this part of your HVAC system is worn, broken, or damaged, your air conditioner could shut down—even if the indoor air feels warm and humid.

Don't Ignore Your Senses

Use your senses to assess the situation. You may already feel the warm air in your home. Now you need to tune into your sense of sight and smell. Look at the main air conditioning unit. Do you see obvious signs of damage, a leak, or anything that seems odd/off? Along with your sense of sight, take in the smell of the AC unit's area. A burning smell or a musty scent may indicate a potentially serious problem. If your initial sensory assessment reveals a possible problem, contact a contractor as soon as possible—especially if you smell smoke or feel heat coming from the AC system.
