When the mercury starts to rise outside, you expect your air conditioner to keep your residence cool. Your AC may be on, but the air issuing from your vents appears too hot.
Here are the most common reasons why this happens and what you need to do to fix it. If you need air conditioning repair in Longmont, the Experts at Service Experts Heating & Air Conditioning can help. Like always, all our AC repair service is supported by a 100% Satisfaction Guarantee.*
1.Your Thermostat is Set Incorrectly
Check the fan setting. If it says “on,” the fan will blow even when the AC compressor isn’t going. This isn’t a problem, but your energy expenses will go up if the fan operates all the time. Adjust the setting to “auto,” and the blower will only operate when the compressor is running. This also means the air coming from the vents will repeatedly appear chilly.
2.Filter is Dirty
The HVAC air filter catches airborne particles that can damage your heating and cooling units. If it becomes too blocked, it can lower airflow. This reduces how much warm air flows over the indoor evaporator coil. If the refrigerant passing through the coil becomes too cold, it freezes, preventing the cooling cycle from taking place. To avoid this, change the filter each month or as suggested by the manufacturer.
3.Not Enough Refrigerant
Refrigerant is critical for air conditioning. It transitions from a low-pressure gas to a high-pressure liquid as it shifts between the indoor evaporator coil and outdoor condensing unit. If refrigerant is leaking, your air conditioner will operate inefficiently and may not create adequate chilled air. It could also cause a frozen evaporator coil, which as we mentioned before, halts the cooling cycle fully. You’ll need aid from an HVAC technician, like one from Service Experts Heating & Air Conditioning, to solve any refrigerant leaks.
4.Condensing Unit is Blocked
The outdoor piece of your AC system is known as a condenser. This is essentially a big heat sink that removes humid air from your house. If the metal fins are covered with yard debris, the condenser can’t run well. Hose down the unit to remove built-up debris and shear back bushes to ensure the condenser isn’t obstructed.
5.Condenser Fan or Compressor has Gone Out
While you’re inspecting the condenser, make sure the big fan at the top of the unit is running. If the fan motor has gone bad, the condensing unit can’t exhaust heat properly, and your air conditioner might start sending muggy air into your home.
Take time to hear the compressor working in the condensing unit too. This is one of the most important parts of your air conditioner, as the part cools the refrigerant. Then, the refrigerant can collect more humidity when it comes back into your residence. If the compressor fails, you’ll probably need to get a new system and set air conditioning installation.
