When the mercury starts rising outdoors, you rely on your air conditioner to keep your home cool. Your AC may be on, but the air blowing from your vents appears too hot.
Here are the most standard reasons why this occurs and what actions you can take about it. If you need air conditioning repair in Livermore, the Experts at Service Experts Heating & Air Conditioning can assist you. Like always, all our AC repair labor is supported by a 100% Satisfaction Guarantee.*
1.Your Thermostat is Set Wrong
Examine the fan setting. If it says “on,” the fan will run even when the AC compressor isn’t running. Nothing’s wrong with this, but your electricity expenses will be bigger if the fan is on constantly. Adjust the setting to “auto,” and the blower will only work when the compressor is running. This also means the air coming from the vents will consistently appear cool.
2.Filter is Clogged
The HVAC air filter traps airborne particles that can damage your heating and cooling units. If it gets too obstructed, it can reduce airflow. This reduces how much warm air flows over the indoor evaporator coil. If the refrigerant flowing through the coil becomes too cold, it freezes, preventing the cooling cycle from happening. To prevent this, replace the filter monthly or as recommended by the manufacturer.
3.Not Enough Refrigerant
Refrigerant is the key to air conditioning. It transitions from a low-pressure gas to a high-pressure liquid as it cycles between the indoor evaporator coil and outdoor condensing unit. If there isn’t enough refrigerant, your air conditioner will operate poorly and may not create adequate cold air. It may also lead to a frozen evaporator coil, which as we already mentioned, halts the cooling cycle altogether. You’ll need help from an HVAC pro, like one from Service Experts Heating & Air Conditioning, to solve any refrigerant problems.
4.Condensing Unit Need to be Cleaned
The outdoor component of your AC system is referred to as a condenser. This is actually a giant heat sink that exhausts humid air from your residence. If the metal fins are covered with yard debris, the condenser can’t work efficiently. Hose down the unit to clear debris that builds up and shear back grass to make sure the condenser isn’t obstructed.
5.Condenser Fan or Compressor has Worn Out
While you’re inspecting the condenser, verify the large fan on the top of the equipment is running. If the fan motor has gone bad, the condensing unit can’t dissipate heat appropriately, and your air conditioner might start sending muggy air into your house.
Pay attention to the sound of the compressor running inside the condensing unit as well. This is what drives your air conditioner, as the part cools the refrigerant. Then, the refrigerant can collect more warmth when it moves back into your house. If the compressor goes out, you’ll likely need to purchase a new unit and schedule air conditioning installation.
