A working AC is every homeowner’s dream come true. But what do you do when your air conditioner is not blowing cold air but still running? Apparently, an AC unit not blowing cold air is a common problem experienced by many homeowners, and it is attributed to several factors.
There are many reasons why your home air conditioner is not blowing cold air, including faulty thermostats and compressor failures. Let’s explore these reasons in detail.
A Malfunctioning Thermostat
One reason your home AC is not blowing cold air is a faulty or wrongly calibrated thermostat. The thermostat is the part of the air conditioning unit that controls the home’s temperature. It sends messages to the AC unit to turn on or off as needed. If the thermostat malfunctions, it cannot communicate effectively with the AC unit, and that could be the reason why your AC is not blowing cold air.
The Filter Is Dirty
If your air conditioner is not blowing cold air, it might mean that the air filter is dirty. The air filter traps dust, dirt, and other pollutants that float in the air inside the house. With time, the air filter becomes overwhelmed with dirt and gets clogged. When that happens, your AC will not blow cold air because the debris restricts airflow.
A Clogged Register or Vents
As the air flows through the AC system, it carries with it several things that can clog the registers or the air vents. The registers or vents carry air-conditioned air to the indoor environment, and return registers take air into the AC unit. If these registers or vents are blocked, the conditioned air will not pass through, and the AC will not blow cold air.
Issues With the Evaporator Coil and Condenser
The evaporator coil in the AC unit removes warm indoor air and then blows conditioned air into your indoor living space. The condenser is usually installed outside, increasing the risk of it getting clogged by debris. If that happens, the AC’s compressor will malfunction, leading to ice forming on the evaporator coil.
The Air Ducts Are Leaking
Air-conditioned air usually passes through a series of insulated ducts. If any of that insulation wears off, leaving space in any part of the air ducts, it creates a potential leaking problem. If your AC is blowing hot air instead of cold air, it might cause leakage in the air ducts.
