Nothing is more frustrating than turning up your air conditioner on a boiling hot day, only to suppose that there is warm air blowing from the vents. There are a number of reasons that your air conditioner could be blowing out warm air, as well as here are a few things you can do about it. The 1st thing you can do if your air conditioner is blowing warm air is to change your air conditioner air filter; Your air conditioner air filter works to detach dirt, dust, pet hair, as well as other debris out of the air in your home, as well as over time, the air filter can become clogged, as well as make it hard for your air conditioner to properly circulate the air inside your home. Most Heating as well as A/C professionals recommend increasing your air conditioner air filter every 30-60 days, especially if you own pets. Another reason your air conditioner may be blowing warm air is because your thermostat is faulty. Older thermostats tend to melt down over time, as well as will not be able to properly create the desired temperature. A thermostat can be replaced abruptly as well as easily, as well as is a smart investment, especially if your thermostat is older than 20 years. Another reason that your air conditioner might be blowing warm air is because your Heating as well as A/C plan may not have enough coolant. Air conditioners use coolant to distribute heat energy from in the house, to the outside through the condenser. If there is not enough coolant inside the system, then your air conditioner will not be able to displace the heat energy accurately. Any licensed Heating as well as A/C professional will be able to abruptly assess the level of coolant inside your plan as well as fill it if necessary. If your air conditioner is blowing cold air, contact your local Heating as well as A/C pro today to get your plan blowing cold again.
