Most people love the summer because it allows them to hold pool parties and barbecues. But after spending a whole day out in the heat, you'll return to your home. There's no worse thing than getting into the house after a long day outside only to realize that your AC is producing warm air. You can be uncomfortable and stressed because of this condition. Luckily, a technician can diagnose your system's problem and repair it immediately. Here are three things they can do to prevent your AC from generating heated air:

Replacing a Blown Fuse

An aircon system consists of an outdoor and indoor unit. The former chills and eliminates warm air from the house, while the latter blows cool air into your home. If the outdoor system malfunctions, it may not work well. This problem may occur if the fuse blows out or the breaker trips. A contractor can examine your panel and confirm whether the circuit is supplying enough electricity. If it isn't, they'll replace the fuse to get your aircon back to working order. 

Repairing Leaks and Adding Refrigerant 

The refrigerant chills the air that passes through your AC. If it's over or undercharged, your unit may produce warm air. The culprits for this problem could be worn-out valves, loose joints, or a poor assembly. Because refrigerants are hazardous, you shouldn't add them yourself because you could damage your aircon and risk your health. A contractor can examine your refrigerant line and repair the leaks. Once all the loopholes are sealed, they'll add refrigerant and charge it appropriately. 

Cleaning Evaporator Coils

When dirt accumulates on the coils, your AC will strain to chill the air. Your coils may also freeze and encourage the mortar to produce warm air. Coils should be cleaned or often replaced, depending on your climate and filter type. While it may be tempting to replace the coil yourself, you may make a blunder that could cause it to thaw again. Fortunately, a technician can troubleshoot and fix this issue. They'll clear all the debris from your coils to keep your aircon running properly. They'll also perform regular tune-ups to prevent this issue from recurring in the future. 

If your AC is producing hot air, you should schedule an HVAC repair as soon as possible. AC technicians are skilled in diagnosing and fixing problems causing units to malfunction. Through their assistance, you can be sure that your home will always be comfortable. Contact an HVAC repair technician today to get started.
