Do Air Conditioners Circulate Air From the Inside?

Where Does the Cool Air in My Home Come From?

Many mistakenly assume it is outside air that is cooled and circulated throughout the home. In reality, however, indoor air is recirculated. How does this occur? All air conditioning systems, such as Mitsubishi and Bryant heating and air conditioning units, remove hot air and inject cool air into your home in a similar way:

• The compressor…
  The heart of your cooling system, the compressor circulates and pressurizes coolant. It is this pressurization, the turning of the refrigerant from liquid to gas, that lowers refrigerant to a cooler temperature. This process likewise lowers the temperature of the air surrounding it – air sourced from your air return. After it is cooled, this air is then recirculated back through your home. What gets all that air where it needs to go – and distributes it back into your home? You system’s fan and ductwork.
• The condenser coil…
  After this process occurs, the condenser of your heating and cooling systemtransforms the once cool refrigerant gas back into a liquid. Working like a miniature radiator, the condenser also draws liquid out of air that passes through it, dehumidifying the air that is recirculated to your home to keep you more comfortable.
• The evaporator coil…
  After the refrigerant leaves the condenser as a liquid, it enters the evaporator through a small hole. Pressure drops, and the liquid begins transforming to gas once again. At this point, the low-pressure gas is ready to make the trip back to the compressor. Once it returns, hot air will be passed over it once again, and the circuitous process repeated until the desired temperature, set by your thermostat, is achieved.

Still Not Sure Where the Air Comes From?
Hopefully, you change your air filter regularly. If you do, you know where your air return is located. This is where air from your home is collected before it is whisked away to be cooled and recirculated by the seemingly mystical combination of components and refrigerant described above. This is why changing your air filter is so important. Dirt from the filter can likewise soil system components – and the air you breathe – making it essential to stay on top of air filter maintenance. Without this simple maintenance, airflow is reduced, and system components become increasingly soiled. Eventually, this will result in the need for professional cleaning and maintenance. In extreme cases, this can also cause your system to overheat, putting excess strain on system components, which could become permanently damaged.

Heat Pump Blowing out Hot Air? Here’s Why.

On a miserably hot and humid summer day, the last thing you want to deal with is a heat pump that is blowing out hot air. Before you dial your friendly neighborhood repairman, take a pause. You may be able to handle the issue yourself…

Three D-I-Y Fixes for A/C Blowing Hot Air

1. Improper thermostat setting.
   You’re busy – and so is your family. Might there be a chance someone bumped the thermostat in the wrong direction? Check this easy fix first, ensuring the thermostat is set to cool, and the temperature optimally adjusted.
2. Dirty air filter.
   It’s easy for cleaning chores to get ahead of you, especially one like this that are out of sight, out of mind. However this is the most common cause of system malfunctions – and repair calls – and it’s easily addressed by you. Pop open the door covering your air filter. If it looks like the beginnings of a new life form, it’s well overdue for a change. All that dirt and dust is preventing necessary air flow, and causing your coil to freeze up. Change it – and now for the hard part: Thawing your coils. For this you’ll have to turn off your system and let it thaw naturally, which could take 2 to 24 hours. NEVER clear ice by hand, which could damage fragile components. And NEVER forget to change the air filter again. It not only results in inconvenient repair issues, but causes your system’s early demise. Add it to your calendar, keeping extra filters on-hand to swap out old for new every 3 months, at a minimum.
3. Dirty outside unit.
   Check the outside unit – that’s the big metal box you ignore until it’s time to weed eat. Inspect the coils and coiling fins to see if they need cleaning. If they’re jammed with debris, it may be smothering the evaporator. Gently remove dust, dried leaves and grass with a soft brush, taking care not to bend the fins. Keep shrubbery, grass and weeds trimmed away – all heating and cooling systemsneeds to breathe.

Still Blowing Hot? You May Need Professional Help to Address:

• Coolant levels.
  Low coolant levels can effect system pressure and reduce cooling capacity, causing your heat pump system to freeze. (Overfilling can also effect performance, so don’t attempt to D-I-Y.) Dangerous to you and the environment, refrigeration adjustment should always be left to a professional.
• Dirty coils.
  Another side-effect of a dirty air filter is a dirty evaporator coil, which can likewise cause your system to blow hot air. You can change your filter – but you’ll need professional assistance for this cleaning.
• Reversing valve malfunction.
  Sometimes in heat pump systems, the reversing valve that switches the system from air conditioning to heating function gets stuck. When this occurs the system can get stuck in ‘heating’ mode. Luckily, this part can be easily swapped out by a pro.
