Your air conditioner has no concept of time and is susceptible to a breakdown or malfunction at any time of the day or night. While certain issues can wait until for a scheduled appointment time, others warrant a call for emergency service, including the following:

• An AC unit that won’t turn on. This is an obvious one—if it’s a hot day and your AC unit simply isn’t working, call BVS for 24-hour AC repair in Katy!
• A lack of cold air (or any air at all). One of the most obvious signs of an impending repair is a blast of warm air coming from your vents. Before you call, check the thermostat to ensure it is set to “cool” rather than “heat” and that the temperature is set to several degrees below the ambient temperature in the room. Click here for a complete guide of what to check before you call your HVAC company!
• Strange smells (especially a burning or gunpowder smell). This could indicate a problem with your AC fan or compressor, or that a circuit board or fan motor has shorted out.
• Strange noises. If you hear something that sounds like metal hitting metal, a part may be loose, or your fan blades could be out of balance or broken. If you hear loud screeching, it could be a broken compressor or fan belt.
• Frozen evaporator coil. While you may be able to get the evaporator coil to thaw on its own, you’re then dealing with large amounts of leakage around the unit. It’s best to call for emergency AC repair if you’re having this issue.
• Refrigerant or water leakage. While a bit of water leakage isn’t cause for alarm, excess moisture or pooling around the unit requires attention and, if left untreated, can lead to property damage or mold growth.
