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: How do I know if my AC capacitor is bad?

• <div><p>Signs that your air conditioner capacitor is bad or failing include a range of symptoms. The AC unit may not turn on at all, or it might struggle to start before shutting down randomly or in the middle of a cooling cycle. You might hear a humming or banging noise when it attempts to start, or the compressor might hum without the unit actually running. Other indicators include a smell or smoke coming from the unit, the blower circulating room-temperature air instead of cold air, and an unexpected increase in your energy bills.</p></div>

Q: How often should my air conditioner be serviced?

• <div><p>To keep your air conditioner in good working condition, you should have it serviced by a professional at least once per year, ideally in the spring before the cooling season begins. If your AC unit is 10 years or older, consider servicing it twice a year (once in the spring and once in the fall) to catch potential problems early and help it reach its full lifespan. During a service visit, a technician will inspect, clean, and replace parts as needed. Regular maintenance helps avoid costly repairs. As a DIY task, you can also clean the evaporator coils annually.</p></div>

Q: Should you hear air coming out of vents?

• <div><p>It&rsquo;s normal to hear a low humming sound as air moves through your vents. Most of the time, you probably won&rsquo;t even notice it. However, if that sound becomes disruptive or if you hear more concerning noises (such as rattling, clicking, banging, hissing, or grinding), there might be a problem with your HVAC system.</p></div>

Q: Are mini-splits cheaper to run than central air?

• <div><p>Yes, mini-split systems are generally less expensive to run than central air conditioners and are significantly more energy-efficient. Because mini-splits do not rely on ductwork, they avoid the energy loss associated with ducted systems, allowing cooled or heated air to reach its destination more efficiently. Additionally, they offer zoned control, meaning you can run units in individual rooms and turn them off in unoccupied areas. This capability can lead to energy savings of about 30% compared to a central air system, resulting in a lower monthly energy bill.</p></div>
