What is the most expensive part to replace on an AC unit?

• <div><p>An AC compressor is one of the most expensive parts to replace on an AC unit if it breaks. You’ll pay up to $2,300 if you need a new one. If your AC is blowing warm air, there doesn’t seem to be a lot of air coming out of the ducts at all, or the unit cycles on and off a lot, you may have a broken compressor. Call a pro to check out your system. </p></div>

Can I build a deck over my HVAC unit?

• <div><p>Yes, you can build a deck over your outdoor HVAC unit, but you need to leave at least 5 feet of vertical clearance above the unit. If you don’t want your deck to be that high off the ground, you could <a href="https://www.angi.com/articles/how-to-build-floating-deck.htm">build a floating deck</a> in another part of your yard—again, as long as you leave at least 4 feet of horizontal space between the deck and your AC unit.</p></div>

Q: When should I replace my furnace and air conditioner?

• <div><p>If both your furnace and AC unit are more than a decade old, it may be a good idea to replace both of them. However, your furnace can last up to three decades, and your air conditioner can typically last up to 15 years, so consulting with a pro before deciding to replace both of them is best. If it&rsquo;s before that time limit for each, you can fix many problems with repairs or just replace one.</p></div>

Q: Should I turn off my AC if it’s blowing hot air?

• <div><p>Yes, it&rsquo;s best to turn off an AC unit that&rsquo;s blowing hot air to prevent system damage and avoid expensive energy bills. If you let the AC continue running, it will put more strain on the condenser coil and compressor. Plus, if the AC is blowing hot air because of a refrigerant leak, it can also lead to a frozen evaporator coil.</p></div>

Q: Is it cheaper to run a window unit or central AC?

• <div><p>It depends on the size of the space you&rsquo;re cooling down. If you&rsquo;re looking for the most affordable way to cool an entire house over a long period of time, then central air will be more cost-effective. But when it comes to cooling down a couple of rooms or one floor, a window unit may be the cheaper option, with both a lower cost to install and less energy used to run.</p></div>
