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: 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: Should I repair or replace my air conditioner?

• <div><p>When deciding whether to repair or replace your air conditioner, several factors should be considered. It is generally worth repairing the unit if it's less than 10 years old, the warranty is still active, and you're dealing with a one-off issue. Most central AC units last about 15 years, while window units last 8 to 10 years. If your unit is approaching or has surpassed the 10-year mark and requires frequent or costly repairs (e.g., over $5,000), replacement is often the more sensible long-term investment. For older, inefficient, or out-of-warranty units experiencing multiple problems, replacing it is typically the better choice.</p></div>

Q: How do I extend the life of my window AC?

• <div><p>To make the most out of your AC, consider implementing the following best practices: </p><ul><li><p><a href="https://www.angi.com/articles/what-size-ac-unit-do-i-need.htm">Choose the right size AC for your home</a> to ensure your unit runs as efficiently as possible.</p></li><li><p>Choose a window with shade, as direct sunlight can cause your AC unit to overheat. </p></li><li><p>Clean or replace the filter at least every two months. </p></li><li><p>Inspect the AC&rsquo;s fan and straighten it if necessary. </p></li><li><p>Discontinue use immediately if you suspect a malfunction, as running the AC while broken can lead to significant issues. </p></li><li><p>Turn off (or adjust the temperature) when you leave the house. </p></li></ul><p></p></div>

Q: Is it worth replacing an AC coil, or should I replace the entire system?

• <div><p>Deciding whether to replace just the AC coil or the entire system depends on the age of your unit and the overall cost. Replacing a coil is less expensive than a full system replacement, but it can still be a pricey repair. If your HVAC system is relatively new and still under warranty, or if the replacement cost is significantly lower than a new system, replacing the coil can be a worthwhile investment that restores efficiency and extends the unit's life. However, for older systems (nearing the end of their 10-15 year lifespan) or those with extensive damage, it is often more cost-effective to replace the entire AC unit. Mismatched coils in an older system can lead to inefficiency and future breakdowns, so a full replacement ensures optimal performance and avoids further costly repairs.</p></div>
