If your house isn't cooling, it can turn a dreamy summer day into a nightmare. Below are a few tips to check before calling for service. A quick check can save time and money.
If your thermostat is blank or has a blinking battery light or symbol on the thermostat, it indicates that the batteries need to be changed. Most thermostats require AA or AAA batteries.
Sometimes a high voltage breaker can trip and cause the unit to stop working. If that is the issue, flip it back and you should be back in business.
If the filter is dirty the unit will run continuously and the temperature in you house will have a difficult time keeping up. A simple change may be all you need to address the situation.
If ice covers your coil, or liquid that couldn't have come from another source surrounds the line, your line is likely leaking refrigerant and a professional inspection is warranted.
If your house isn't heating, these few tips may help save you from sitting out in the cold.
