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 DIY an AC coil replacement?

• <div><p>No, a licensed <a href="https://www.angi.com/nearme/air-conditioning-repair/">local AC repair technician</a> must replace AC coils due to the need to handle hazardous refrigerants. Attempting DIY poses risks to your personal safety, as most refrigerants are flammable and toxic. You also risk voiding your warranty with the HVAC company and causing damage to the unit.</p></div>

Q: How much does a new air conditioner capacitor cost?

• <div><p>A new air conditioner capacitor will cost less than replacing the entire air conditioner system. While a capacitor itself will cost between $8 and $25, paying a professional to replace an AC capacitor will cost $180 on average. It&rsquo;s not safe to replace an air conditioner capacitor on your own. </p></div>

Q: What are the three top reasons to purchase an HVAC maintenance contract?

• <div><p>The top reason to purchase an HVAC maintenance contract is the fact that it ensures you are detecting problems before they turn into expensive fixes. Secondly, this type of contract provides priority service, which is nice if it&rsquo;s peak busy season. Finally, an HVAC maintenance contract provides discounts on parts and labor for repairs, which can save you a good amount of money if your unit breaks.</p></div>

Q: Can you run a window unit and central air together?

• <div><p>Though it may seem redundant, you can absolutely have a central AC unit and a window AC in your home. In fact, if you place a window AC unit near your central air, it can help move the cooler air throughout your home. But doubling up on your AC methods can get pricey, so factor in cost accordingly.</p></div>

Nyc is one tough town. Finding people who know what they are doing and are good communicators and are rock-hard reliable are rare. And add to that the attribution of honesty coming in below estimates and it's a rare breed. HVAC is notoriously hard to obtain good honest reliable and skilled help...
