On the flip side, an oversized generator may seem like a safe bet, but it can lead to unnecessary fuel consumption and higher installation costs. The goal is to size your generator to match your essential electrical needs during an outage.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Start by Listing Essential Appliances<\/h2>\n\n\n\n<p>The first step in determining the right size generator is making a list of the essential appliances and systems you want to keep running. Think about items like:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Refrigerator and freezer<\/li>\n\n\n\n<li>Lighting circuits<\/li>\n\n\n\n<li>Sump pump (if applicable)<\/li>\n\n\n\n<li>Well pump (if applicable)<\/li>\n\n\n\n<li>Medical equipment<\/li>\n\n\n\n<li>Security system<\/li>\n\n\n\n<li>Wi-Fi router and phone chargers<\/li>\n<\/ul>\n\n\n\n<p>Don\u2019t forget about conveniences like the microwave or coffee maker if they&#8217;re important to you during an outage. This list will serve as your starting point for calculating the total wattage you need.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Don\u2019t Overlook HVAC Systems<\/h2>\n\n\n\n<p>Heating and cooling systems are often the biggest power draws in a home. If staying comfortable year-round is important to you during a power outage, you\u2019ll need to consider the size and type of your HVAC systems. Central air conditioners, electric furnaces, and heat pumps all have high starting wattage requirements. This is why it&#8217;s crucial to know not just what appliances you\u2019ll run, but how many of them might need to start up simultaneously. A professional assessment will help determine if your generator can handle these systems or if you should prioritize space heaters or fans instead.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Calculate Total Electrical Load<\/h2>\n\n\n\n<p>Once you\u2019ve listed all your essential appliances, the next step is to calculate their combined wattage. Keep in mind that some appliances, like refrigerators and HVAC systems, require extra power when they start up. This is called \u201cstarting watts\u201d or \u201csurge watts.\u201d Add up the running watts and factor in the surge watts to ensure your generator can handle peak demand.<br><br>A typical home might require anywhere from 5,000 to 7,500 watts to power essentials, while whole-home coverage could need 20,000 watts or more. That\u2019s why it\u2019s important to be clear on your must-haves.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Consult With a Professional for Accurate Sizing<\/h2>\n\n\n\n<p>While online calculators can give you a rough idea, getting an accurate load assessment from a licensed electrician is the best way to ensure you\u2019re choosing the right generator size. At JN Electrical, we take the guesswork out of generator installation by performing a detailed evaluation of your home\u2019s electrical demand and helping you select a generator that fits your needs and budget.<br><br>Power outages are unpredictable, but with the right backup generator, you\u2019ll never be left in the dark.<\/p>\n\n\n\n<p class=\"has-text-align-center\"><strong><a href=\"\/contact\/send-message\" target=\"_blank\" rel=\"noopener\" title=\"Contact JN Electrical, and you\u2019ll \u201cFeel the Difference!\u201d\">Contact JN Electrical, and you\u2019ll \u201cFeel the Difference!\u201d<\/a><\/strong><\/p>\n","protected":false},"excerpt":{"rendered":"<p>When it comes to generator installation in Bowersville, knowing the right size generator for your home is key to keeping the lights on and your family comfortable when the power goes out. <\/p>\n","protected":false},"author":1,"featured_media":1462,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[169],"tags":[164,172],"class_list":["post-1448","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-generators","tag-bowersville","tag-generator-installation"],"aioseo_notices":[],"_links":{"self":[{"href":"https:\/\/www.jncomfort.com\/blog\/wp-json\/wp\/v2\/posts\/1448","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.jncomfort.com\/blog\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.jncomfort.com\/blog\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.jncomfort.com\/blog\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/www.jncomfort.com\/blog\/wp-json\/wp\/v2\/comments?post=1448"}],"version-history":[{"count":9,"href":"https:\/\/www.jncomfort.com\/blog\/wp-json\/wp\/v2\/posts\/1448\/revisions"}],"predecessor-version":[{"id":1463,"href":"https:\/\/www.jncomfort.com\/blog\/wp-json\/wp\/v2\/posts\/1448\/revisions\/1463"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.jncomfort.com\/blog\/wp-json\/wp\/v2\/media\/1462"}],"wp:attachment":[{"href":"https:\/\/www.jncomfort.com\/blog\/wp-json\/wp\/v2\/media?parent=1448"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.jncomfort.com\/blog\/wp-json\/wp\/v2\/categories?post=1448"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.jncomfort.com\/blog\/wp-json\/wp\/v2\/tags?post=1448"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
