There is such a thing as <\/span><i><span style=\"font-weight: 400;\">too<\/span><\/i><span style=\"font-weight: 400;\"> long, however! Air conditioners are designed to run in cycles where the compressor comes on for 15\u201320 minutes and then cycles down until the thermostat registers the need for more cooling. If you start to notice that your AC <\/span><i><span style=\"font-weight: 400;\">never<\/span><\/i><span style=\"font-weight: 400;\"> seems to cycle down or the fan runs continuously, you may need to have <\/span><a href=\"\/air-conditioning\" target=\"_blank\" rel=\"noopener noreferrer\"><span style=\"font-weight: 400;\">air conditioning repair in Brighton, MI<\/span><\/a><span style=\"font-weight: 400;\">.\u00a0<\/span><\/p>\n<p><!--more--><\/p>\n<h2><b>Yes, this is a serious problem<\/b><\/h2>\n<p><span style=\"font-weight: 400;\">If you think an AC that just keeps blowing out cool air during the worst heat of summer sounds fine \u2026 it\u2019s not. You want your house to be cool, but you don\u2019t want it <\/span><i><span style=\"font-weight: 400;\">too<\/span><\/i><span style=\"font-weight: 400;\"> cool\u2014and that\u2019s what you\u2019ll eventually get if the compressor doesn\u2019t cycle off. A nonstop AC is also a tremendous money-waster that will send electrical bills through the roof. Worst of all, the massive unrelieved strain placed on the air conditioner\u2019s parts, in particular the compressor and the blower motor, will lead to extra repair problems and an early replacement for the system.<\/span><\/p>\n<h2><b>What can cause a runaway AC<\/b><\/h2>\n<p><span style=\"font-weight: 400;\">Here are the most common causes of an AC running too long:<\/span><\/p>\n<ul>\n<li><b>Stuck motor relay: <span style=\"font-weight: 400;\">This is an electrical problem with the compressor or blower motor. The relay is what permits electrical current to flow to the motor. If it gets stuck, it will allow current to continue to flow to the motor and won\u2019t turn off until the power is cut off at the circuit breaker. This is the most frequent source of an AC that truly won\u2019t turn off at all.<\/span><\/b><\/li>\n<li><strong>Thermostat problems:<\/strong> <span style=\"font-weight: 400;\">Since the thermostat controls when the AC turns on and off, it\u2019s often the cause of an air conditioner that isn\u2019t doing one or the other correctly. The thermostat might read indoor temperatures as hotter than they are, forcing it to keep the AC running longer than necessary. The thermostat may also lose the connection to the AC that signals when to shut off either the blower or the compressor\u2014maybe both.<\/span><\/li>\n<li><strong>Leaking refrigerant:<\/strong> <span style=\"font-weight: 400;\">A nonstop AC is often an early warning that the system is losing refrigerant to leaks. As refrigerant escapes, the air conditioner will lose its cooling capacity and need to stay on longer to cool the house. If the leaks aren\u2019t repaired, the AC\u2019s compressor will eventually burn out, so this is definitely something you want to be fixed ASAP.<\/span><\/li>\n<li><strong>Dirty condenser coil:<\/strong> <span style=\"font-weight: 400;\">The outdoor coil in the condenser cabinet can pick up dust and grime over the season. This makes it harder for the AC to release heat outdoors, causing the AC to have to run for longer because of the trapped heat. Regular maintenance in spring is the best way to avoid a dirty condenser coil. If you have this problem at the end of the summer, call us to chemically clean off the coil.\u00a0<\/span><\/li>\n<li><strong>Undersized AC:<\/strong> <span style=\"font-weight: 400;\">Is this a new air conditioner? Then the problem might be that whoever installed it (probably an amateur) put in a unit that is too small for the house. The AC will run overtime because it\u2019s trying to reach a low temperature it can\u2019t reach. The only way to fix this is to replace the unit.<\/span><\/li>\n<\/ul>\n<p style=\"text-align: center;\"><b>First Choice Heating &amp; Cooling serves Fenton, Linden, Holly, and the surrounding areas. <\/b><a href=\"\/contact\/send-message\" target=\"_blank\" rel=\"noopener noreferrer\"><b>If your home had a voice \u2026 it would call First Choice.<\/b><\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p>If you start to notice that your AC never seems to cycle down or the fan runs continuously, you may need to have air conditioning repair<\/p>\n","protected":false},"author":1,"featured_media":0,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[70],"tags":[92,90,101],"class_list":["post-1166","post","type-post","status-publish","format-standard","hentry","category-air-conditioning-service","tag-air-conditioning-maintenance","tag-air-conditioning-repair","tag-brighton"],"aioseo_notices":[],"_links":{"self":[{"href":"https:\/\/www.firstchoiceheat.com\/blog\/wp-json\/wp\/v2\/posts\/1166","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.firstchoiceheat.com\/blog\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.firstchoiceheat.com\/blog\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.firstchoiceheat.com\/blog\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/www.firstchoiceheat.com\/blog\/wp-json\/wp\/v2\/comments?post=1166"}],"version-history":[{"count":4,"href":"https:\/\/www.firstchoiceheat.com\/blog\/wp-json\/wp\/v2\/posts\/1166\/revisions"}],"predecessor-version":[{"id":1241,"href":"https:\/\/www.firstchoiceheat.com\/blog\/wp-json\/wp\/v2\/posts\/1166\/revisions\/1241"}],"wp:attachment":[{"href":"https:\/\/www.firstchoiceheat.com\/blog\/wp-json\/wp\/v2\/media?parent=1166"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.firstchoiceheat.com\/blog\/wp-json\/wp\/v2\/categories?post=1166"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.firstchoiceheat.com\/blog\/wp-json\/wp\/v2\/tags?post=1166"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
