Q: Can I clean AC coils myself?

Just make sure that the power to your AC system is off before you begin. You&rsquo;ll need some basic tools and supplies, including a soft brush, cloth, screwdriver, and a commercial or homemade cleaning solution. Cleaning your coils will only cost about $10.</p></div>

Q: Can running AC too cold cause mold?

• <div><p>Yes, running your air conditioning unit too cold can cause condensation in the air ducts and built up moisture on the air filter, resulting in a breeding ground for mold and mildew. Mold and mildew growth can irritate those with respiratory issues, so it&rsquo;s best to keep your AC running at a normal temperature.</p></div>

Q: What’s the difference between an AC unit and a dehumidifier?

• <div><p>Air conditioners and dehumidifiers are actually quite similar, though they perform different jobs. Dehumidifiers reduce moisture in the air, while air conditioners work to cool the home. A good central AC unit will naturally perform a certain level of dehumidification due to its design, but it will not be able to handle excessive levels of moisture.</p></div>
