If a mildew smell is noticeable when you first turn the A/C on, this method may help. The 3% solution sold in stores will work.  Do not use alcohol, as this is flammable and could start a fire. Do not use bleach, as those fumes are toxic and bleach could damage the unit. While safer than bleach or alcohol, hydrogen peroxide should still be clearly labelled and kept out of the reach of children. Spray the intake area and outflow area on the front of the unit.  Avoid getting spray in eyes or inhaling it.  Once it settles on surfaces, the fumes are no longer a concern. Rinse hands after spraying. Then turn the unit back on. Spraying when the unit is turned off for the night is ideal, as that allows plenty of time to dry before morning. If this method isn't sufficient, remove the filter, with the unit off, and spray further inside the unit.  Place a drip tray underneath the unit to catch any drips, which might otherwise bleach carpet, fabric, or wood. A turkey basting tray is one possible option. Before the condensate evaporates, that's the ideal breeding period for microbes.  While the unit is on, the temperature extremes and continuous flow of condensate washing old water outside (you may see it dripping) prevents the build-up of microbes.

One-sentence summary -- Look and smell for signs of mildew. Fill a spray bottle with hydrogen peroxide. Turn the unit off. Allow it to dry. Do a deeper clean if needed. Avoid turning the unit on and off often.

Q: Early symptoms aren't serious enough to interfere with your normal activities or daily life. When the condition starts to progress, though, you'll notice yourself having trouble with normal activities. People usually continue to experience the early symptoms, but more severely. If left undiagnosed or untreated, the early, mild symptoms of asthma can get progressively worse. This is especially true if you don't identify your triggers and avoid them. If you have asthma, your airways can get closed off because of the constriction or inflammation from the disease. Your body will respond by trying to clear your airways through coughing. While the coughs you get during a bacterial infection are wet, mucus-y coughs, asthma coughs tend to be dry, with very little mucus.  If coughing begins or worsens at night, it may be asthma. A common symptom of asthma is nighttime coughing, or coughing that gets worse right after you wake up.  In more progressed cases, coughing extends into the day. Asthmatics often notice a wheezing or high-pitched whistling when they exhale. This is caused by the constriction of airways. Note when you hear the sound. If it's at the very end of exhalation, it's an early sign of mild asthma. But as the condition progresses from mild to moderate symptoms, you’ll wheeze or whistle throughout the entire exhalation. "Exercise-induced bronchoconstriction" is a type of asthma seen in those who've just done something strenuous, like exercising. The airway constriction will leave you tired and gasping for air sooner than you should be, and you may have to give up the activity before you want to. Compare how long you can normally exercise to instances when fatigue and shortness of breath limit you. To get more oxygen in the constricted lungs, the body increases its respiration rate. Place your palm over your chest and count how many times your chest rise and falls in one minute. Use a stopwatch or clock with a second hand, so you can time out an accurate minute. A normal respiratory rate is between 12 and 20 breaths in 60 seconds. With moderate asthma, your respiratory rate can be from 20 to 30 breaths per minute. Though the coughing from asthma is different from that from a cold or flu, bacteria and viruses can trigger asthma. Look for signs of infection that may be causing the asthma symptoms: sneezing, runny nose, sore throat, and congestion. If the coughing dark, green, or white mucus, the infection may be bacterial. If it's clear or white, it may be viral.  If you see these infection symptoms combined with noise on exhalation and gasping for breath, you likely have asthma triggered by an infection. See a doctor to find out exactly what's going on.
A: See a doctor even for mild symptoms. Notice excessive coughing. Listen for noise when you exhale. Take note of unusual shortness of breath. Be on the watch for rapid breathing. Don't ignore cold or flu symptoms.

Article: Deep down, everyone is a nerd about something. Learn a little about her hobbies, or whatever makes her happy outside of your relationship. Show genuine interest in them, and she'll appreciate the effort. You don't have to fake enthusiasm, or even fully understand what she's talking about. Just make an effort to follow her explanations. Don't take the relationship for granted. Set aside time to give each other your full attention, and put in the effort to make it feel special. Does she stop to pet dogs on the street? Did she call something you did cute in conversation? Make a mental note of these moments, and she'll probably tell you everything you can do to make her smile without even knowing it. "Sexy" and "gorgeous" can be great in the right context, but people need recognition on other levels as well. Make sure your girlfriend knows you appreciate her intellect and skill. Every relationship is different. Remember to think of what your girlfriend enjoys, instead of repeating what worked on your last significant other. Sometimes, you have to let your girlfriend be mad, or sad, or whatever it is she's feeling. If she's going through a rough emotional time, don't tell her that everything's okay or that she just needs to cheer up. She should be able to trust you with every emotion she has, and seek support even when she's not up to smiling.
