Q: What AC tonnage do I need for my house?

• <div><p>The general rule of thumb for figuring out <a href="https://www.angi.com/articles/infographic-how-tonnage-affects-your-ac.htm">how much AC tonnage you need</a> in your home is that for every 500 to 600 square feet of space you need to cool, you&rsquo;ll need one ton of AC cooling power. So, a 1,000-square-foot home will need 2 tons of AC power. </p></div>

Q: What’s the difference between a home surge protector and an HVAC surge protector?

• <div><p>The difference between a home surge protector and an HVAC surge protector is that an HVAC surge protector is designed to protect the components inside your HVAC unit while a home surge protector is installed near appliances and meant to protect your entire home. There are three tiers of whole-house surge protectors, and they are more expensive to install than HVAC surge protectors.</p></div>

Q: Where does Freon go in a home AC unit?

• <div><p>Freon will go in the refrigerant lines near the back of your AC unit. Look for small ports with caps on a thin copper line&mdash;the Freon goes into those ports. You are best off hiring a licensed HVAC professional who can complete the job safely and correctly.</p></div>

Q: How long should my HVAC last?

• <div><p>With the proper maintenance and repairs, your HVAC can last <b>15 to 25 years</b>. However, it depends on the type of equipment you have and the average lifespan of each, including:</p><ul><li><p><a href="https://www.angi.com/articles/oil-furnace-replacement-cost.htm">Oil furnace</a>: <b>10&ndash;15 years</b></p></li><li><p><a href="https://www.angi.com/articles/common-gas-furnace-prices.htm">Gas furnace</a>: <b>20&ndash;30 years</b></p></li><li><p><a href="https://www.angi.com/articles/how-much-does-boiler-installation-cost.htm">Boiler</a>: <b>20&ndash;35 years</b></p></li><li><p><a href="https://www.angi.com/articles/how-much-does-installing-new-ac-cost.htm">AC unit</a>: <b>7&ndash;20 years (location dependent)</b></p></li><li><p><a href="https://www.angi.com/articles/heat-pump-systems-explained.htm">Heat pump</a>: <b>10&ndash;20 years</b></p></li><li><p><a href="https://www.angi.com/articles/how-ductless-mini-split-heat-pump-works.htm">Ductless mini-split</a>: <b>10&ndash;30 years</b></p></li></ul><p></p></div>

Q: How many quotes should I get for HVAC replacement?

• <div><p>You should get anywhere from three to five quotes for HVAC replacement to get an idea of the average cost of a new unit. Although this quote-collecting process can be time consuming, it allows you to compare what work is required, what type of unit you should install, and how much you should expect to pay for the service.</p></div>
