But people still find it hard to make the choice to replace an aging furnace because of the costs involved. \u201cWhy not just keep repairing it?\u201d they think. The problem is that repairs can turn out to be far more costly than investing in replacing the furnace.\u00a0<\/span><\/p>\n<p><span style=\"font-weight: 400;\">We\u2019ll take a look at this common conundrum.

One of the most popular is the \u201cRule of 5,000,\u201d which states:<\/span><\/p>\n<p style=\"padding-left: 30px;\"><i><span style=\"font-weight: 400;\">If the cost of a repair (in dollars) multiplied by the age of the furnace (in years) exceeds 5,000, than the repair is not worth the price and a replacement is a more cost-effective option.<\/span><\/i><\/p>\n<p><span style=\"font-weight: 400;\">We\u2019ll examine this in action to give you an idea of how this measurement works.<\/span><\/p>\n<p><b>Example 1:<br \/>\n<\/b><span style=\"font-weight: 400;\">You have a gas furnace that\u2019s 12 years old. This isn\u2019t exceptionally old\u2014gas furnaces often work for 15 years\u2014but it\u2019s probably past its warranty and is reaching the point where a replacement becomes more appealing. The furnace stops working because of a <a href=\"https:\/\/www.robbinsheating.com\/blog\/heating-service\/5-most-common-furnace-repairs-youll-need\/\">common furnace repair issue<\/a>, and one of our technicians gives you a repair estimate of $500. Multiply 12 by 500 and you get 6,000. That\u2019s significantly more than 5,000 and enough to make a replacement the better choice.<\/span><\/p>\n<p><b>Example 2:<br \/>\n<\/b><span style=\"font-weight: 400;\">Let\u2019s stick with the same 12-year-old furnace.

That\u2019s enough lower than 5,000 for the repair to look like a cost-effective option.<\/span><\/p>\n<h2><b>Consider Furnace Replacement When Repair Costs Reach 50% of Replacement Cost\u00a0<\/b><\/h2>\n<p><span style=\"font-weight: 400;\">This is a quicker rule of thumb that\u2019s best used for a furnace that\u2019s already at or around 15 years of service. It states:<\/span><\/p>\n<p style=\"padding-left: 30px;\"><i><span style=\"font-weight: 400;\">If any single repair is more than 50% of the cost of installing a new furnace, the repair is too expensive.<\/span><\/i><\/p>\n<p><span style=\"font-weight: 400;\">The tricky part of this rule is determining the cost of the new furnace, since you have several options for types of furnaces with different price points, such as condensing furnaces with higher efficiencies. However, we think that regardless of the cost of the projected furnace replacement, a repair price that\u2019s 50% of that is far too much to pay.\u00a0<\/span><\/p>\n<h2><b>Ask an HVAC Professional Whether Furnace Repair or Replacement Makes More Sense<\/b><\/h2>\n<p><span style=\"font-weight: 400;\">We think this is the best way to make the choice: ask an honest and experienced HVAC pro for an opinion on whether a repair is worth it or not.

A common guideline is the 50% rule: if the repair costs more than half the price of a new furnace, replacement may offer better long-term value.<\/span><\/p>\n<p><b>Question: Should I repair or replace a 15-year-old furnace?<\/b><b><br \/>\n<\/b><b>Answer:<\/b><span style=\"font-weight: 400;\"> A 15-year-old furnace may still be worth repairing if the issue is minor and the system has otherwise been reliable. However, if repairs are becoming frequent, efficiency is declining, or the latest repair is costly, replacing the furnace may be the more practical investment.<\/span><\/p>\n<p><b>Question: What is the Rule of 5,000 for furnace repair?<\/b><b><br \/>\n<\/b><b>Answer:<\/b><span style=\"font-weight: 400;\"> The Rule of 5,000 helps homeowners compare furnace age with repair cost by multiplying the system\u2019s age by the estimated repair price. If the result is greater than 5,000, replacement may be more cost-effective than putting additional money into an aging furnace.<\/span><\/p>\n<p><b>Question: What is the 50% rule for furnace replacement?<\/b><b><br \/>\n<\/b><b>Answer:<\/b><span style=\"font-weight: 400;\"> The 50% rule suggests considering furnace replacement when a repair costs more than half the price of installing a new system. This guideline is especially useful for older furnaces, but factors such as efficiency, overall condition, and recent repair history should also be considered.<\/span><\/p>\n<p><b>Question: How do I decide whether to repair or replace my furnace?<\/b><b><br \/>\n<\/b><b>Answer:<\/b><span style=\"font-weight: 400;\"> Consider the furnace\u2019s age, repair estimate, efficiency, condition, and how often it has needed service in recent years. A smaller repair may make sense for a dependable system, while an older furnace with repeated or expensive problems may be a better candidate for replacement.<\/span><\/p>\n<p style=\"text-align: center;\"><a href=\"\/contact\/schedule-service\" target=\"_blank\" rel=\"noopener noreferrer\"><b>Look to us for help when you\u2019ve got an old furnace and you\u2019re not sure if it\u2019s ready for a replacement.<\/b><\/a><b><br \/>\nRobbins Heating &amp; Air Conditioning serves Colorado Springs and the surrounding area.<\/b><\/p>\n","protected":false},"excerpt":{"rendered":"<p>If you have an old furnace, when is it too pricey to continue with furnace repair?<\/p>\n","protected":false},"author":1,"featured_media":0,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":[],"categories":[76],"tags":[89,50,15],"aioseo_notices":[],"_links":{"self":[{"href":"https:\/\/www.robbinsheating.com\/blog\/wp-json\/wp\/v2\/posts\/1499"}],"collection":[{"href":"https:\/\/www.robbinsheating.com\/blog\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.robbinsheating.com\/blog\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.robbinsheating.com\/blog\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/www.robbinsheating.com\/blog\/wp-json\/wp\/v2\/comments?post=1499"}],"version-history":[{"count":11,"href":"https:\/\/www.robbinsheating.com\/blog\/wp-json\/wp\/v2\/posts\/1499\/revisions"}],"predecessor-version":[{"id":2364,"href":"https:\/\/www.robbinsheating.com\/blog\/wp-json\/wp\/v2\/posts\/1499\/revisions\/2364"}],"wp:attachment":[{"href":"https:\/\/www.robbinsheating.com\/blog\/wp-json\/wp\/v2\/media?parent=1499"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.robbinsheating.com\/blog\/wp-json\/wp\/v2\/categories?post=1499"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.robbinsheating.com\/blog\/wp-json\/wp\/v2\/tags?post=1499"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
