Q: Is AC coil cleaning worth it?

• <div><p>Yes, AC coil cleaning is definitely worth it. Cleaning your AC coils ensures your AC unit will function efficiently for the long term. Dirty and grimy AC coils make your unit work harder to cool your home, resulting in higher electric bills. Additionally, having your coils professionally cleaned regularly will reduce the possibility of extensive <a href="https://www.angi.com/articles/ac-service-cost.htm">maintenance and repair costs</a>. </p></div>

Q: Is it worth it to clean mold out of an AC unit?

• <div><p>It depends on the type of AC unit and the extent of the mold growth. For example, if you have a small amount of mold in your central air conditioner, it&rsquo;s worth cleaning it to protect your HVAC system and your health. In situations like these, you can often remove the mold yourself in a couple of hours. On the other hand, if you have a portable AC unit with a severe mold problem, it makes more sense to buy a new one. On average, <a href="https://www.angi.com/articles/how-much-does-installing-new-ac-cost.htm">replacing a portable AC unit costs</a> $100 to $500. </p></div>

Q: 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&rsquo;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&mdash;again, as long as you leave at least 4 feet of horizontal space between the deck and your AC unit.</p></div>

Q: How do I reduce AC startup power for a generator?

• <div><p>To reduce AC startup power for a whole-house generator, install a soft start kit or hard start capacitor, which lowers the initial surge by gradually ramping up the compressor. Using a smart load manager can also help by staggering startup loads, preventing a system overload and future costly repairs.</p></div>

Q: What is the most common rule used for HVAC load calculation?

• <div><p>A common HVAC rule is that for every 500 to 600 square feet of living space, you need 1 ton of heating or cooling capacity. Now that you know this common rule, you also need to know that it isn&rsquo;t very accurate, and a dedicated pro wouldn&rsquo;t use it for your home. If you talk to a pro who won&rsquo;t or can&rsquo;t perform a proper Manual J calculation, consider hiring someone more thorough.</p></div>
