Q: Can you run an air conditioner with a Freon leak?

• <div><p>No, you should not run an air conditioner with a Freon leak. If you think your AC unit is leaking refrigerant, shut it off immediately. When you keep using a leaky air conditioner, it could damage the unit and release more refrigerant. After turning off the AC, have an HVAC pro come take a look at the unit.</p></div>

Q: How do you know when your HVAC is going bad?

• <div><p>Aside from needing HVAC repair, there are times when you may need to replace your unit. <a href="https://www.angi.com/articles/insider-s-price-guide-new-heating-and-cooling-system.htm">HVAC replacement costs</a> <b>$5,000 to $12,500</b>. Here are some telltale signs that your HVAC unit is going bad:</p><ul><li><p>Your unit is 10 years or older.</p></li><li><p>Your home is very humid.</p></li><li><p>The unit keeps cycling without producing cool air.</p></li><li><p>You need to repair the unit frequently.</p></li></ul><p></p></div>

Q: What issues can a dirty air conditioning coil cause?

• <div><p>A dirty air conditioning coil can cause your unit to work overtime, leading to reduced efficiency, higher energy use, more wear and tear, and possible ice buildup. If the coils corrode, refrigerant can leak, causing damage, possible mold growth, and an expensive repair bill. By cleaning your AC coils once a year, you&rsquo;ll have a more efficient unit that&rsquo;s likely to last longer.</p></div>

Q: Is there such a thing as a ventless air conditioner?

• <div><p>Yes, there are <a href="https://www.angi.com/articles/what-are-ventless-portable-air-conditioners.htm">ventless portable air conditioners</a> that don&rsquo;t have exhaust hoses and don&rsquo;t require venting. Instead, they have a water reservoir and cooling pad, which add moisture to the air to make it feel colder. Ventless portable AC units work best in dry climates since humid areas already have a lot of moisture in the air and can&rsquo;t absorb much more. </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>

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...
