Q: What kind of refrigerant does my HVAC system use?

• <div><p>Some HVAC systems tend to use R410A refrigerant, although if you have an older model <a href="https://www.angi.com/articles/what-fair-price-r-22-refrigerant.htm">it may be using R22</a>. R22 is banned due to its harmful environmental and health impacts, and it is a sign that your AC unit is old enough to consider a replacement and the significant efficiency gains that could come with it.</p></div>

Q: Is it normal for my attic to be hot?

• <div><p>It is normal for the attic to be hotter than the rest of the house in the summer, but only by about 10 or 20 degrees. Attics that aren&rsquo;t properly insulated or ventilated can reach temperatures of 130 degrees or more which can cause damage to the home&rsquo;s structure, including the roof, wood framing, and HVAC system. </p></div>

Q: Are HVAC quotes free?

• <div><p>Many HVAC companies offer free quotes and free estimates for repairs and new HVAC systems. Others offer low-cost quotes or apply the cost of the estimates or diagnostics to your final bill if you hire them. Be aware that some companies advertise free HVAC quotes and recoup the costs by charging more for their services. Free HVAC quotes are never truly free&mdash;they cost the company time and effort&mdash;so be a good customer. Also understand that you may end up paying for free quotes in another way if you don&rsquo;t hire a reputable company.</p></div>

Q: Is it safe to keep using my AC unit when it's frozen?

• <div><p>No, it's not safe to keep using your unit when it's frozen. Not only can running a frozen unit lead to damage, but it can also potentially overheat, making it a fire hazard. Therefore, it's always best to turn off the AC unit as soon as you notice any ice.</p></div>

Q: Do return ducts need dampers?

• <div><p>If you know <a href="https://www.angi.com/articles/how-to-identify-supply-and-return-ducts.htm">how to identify supply and return ducts</a>, you&rsquo;ll find that only the supply ducts will have dampers. Although your return ducts can have dampers, it&rsquo;s not common. If you have one return duct that is pulling in too much air, adding a damper to it can help with overall system performance. However, dampers on return ducts are not a necessary addition for most homes.</p></div>
