This is a good time to go over a list of the most common AC problems that can crop up, because this is when you\u2019re most likely to run into one of them and have your comfort put in jeopardy!<\/p>\n\n\n\n<p>If your AC runs afoul from one of the troubles below, you can find excellent professional repair service for your <a href=\"\/service-areas\/northbrook-il\" target=\"_blank\" rel=\"noopener noreferrer\">air conditioning in Northbrook, IL <\/a>with just a call to our team.

The air then continues into the ventilation system and the rest of the house. If this fan isn\u2019t working right, you\u2019ll have a problem with air that isn\u2019t cool enough and airflow that\u2019s too weak. This fan can malfunction because of a worn-down motor. Dust and lack of lubrication may cause the motor to overheat and put a major dent in your comfort. Technicians will need to either<a href=\"https:\/\/www.goservicemax.com\/blog\/air-conditioning-service\/5-signs-air-conditioner-in-trouble\/\"> fix failing AC fan issues<\/a>.<\/p>\n\n\n\n<h3>TWO: Trouble With the Outdoor Exhaust Fan<\/h3>\n\n\n\n<p>There\u2019s another crucial fan for the operation of the AC, and that\u2019s the one in the outdoor cabinet. It does the job of running outdoor air across the condenser coil to allow for the release of heat, which the fan then exhausts. If this fan\u2019s motor malfunctions, the air conditioner will lose its ability to cool.<\/p>\n\n\n\n<h3>THREE: Refrigerant Leaks<\/h3>\n\n\n\n<p>The refrigerant in an AC must remain at its factory set level or else the change in pressure in the system will put the entire cooling system in jeopardy. So not only will you lose indoor cooling, you may have a permanently busted AC when the compressor burns out. Fixing this requires professionals to<a href=\"https:\/\/www.goservicemax.com\/blog\/air-conditioning-service\/dont-ignore-these-signs-that-your-ac-needs-repair\/\"> catch early AC refrigerant issues<\/a>. (You don\u2019t want too much refrigerant added\u2014that is as bad as too little.)<\/p>\n\n\n\n<h3>FOUR: Frozen evaporator coil<\/h3>\n\n\n\n<p>People often assume that ice on the evaporator coil isn\u2019t a serious problem. Just a part of how the AC works. But this is false: the ice means the coil isn\u2019t absorbing enough heat for some reason. It\u2019s not a problem you can solve by scraping off the ice, which may damage the coils. Instead, it usually signals<a href=\"https:\/\/www.goservicemax.com\/blog\/air-conditioning-service\/ac-problems-want-fixed-before-gets-hotter\/\"> AC problems to fix now<\/a>.<\/p>\n\n\n\n<h3>FIVE: Condensate drain clog<\/h3>\n\n\n\n<p>The condensate moisture from the AC\u2019s evaporator coil falls into a pan and then is drained out through a condensate drain. The drain can become clogged with algal growth, and when this happens the overflow from the pan will trigger a switch that will shut down the AC. Call for technicians to clean out the drain so the AC can get back to work.<\/p>\n\n\n\n<h4>When you need your air conditioning problems solved, <a href=\"\/contact\/contact\" target=\"_blank\" rel=\"noopener noreferrer\">turn to ServiceMax<\/a>.
