Q: Why is the AC drip pan not draining?

• <div><p>An AC drip pan may stop draining if there&rsquo;s a clog where the drip pan connects to the drain line. Clogs can form from a lack of cleaning or from rust or corrosion buildup. Cleaning the drip pan at least once per month lowers the chances of debris clogging the drain line. </p></div>

Q: What is the most common rule used for HVAC load calculation?

• <div><p>A common HVAC rule is that for every 500 to 600 square feet of living space, you need 1 ton of heating or cooling capacity. Now that you know this common rule, you also need to know that it isn&rsquo;t very accurate, and a dedicated pro wouldn&rsquo;t use it for your home. If you talk to a pro who won&rsquo;t or can&rsquo;t perform a proper Manual J calculation, consider hiring someone more thorough.</p></div>

Q: How do you remove mold from an air conditioner?

• <div><p>You may be able to <a href="https://www.angi.com/articles/how-rid-your-ac-mold-and-more.htm">clean mold from your air conditioner</a> in some cases. If the mold growth only takes up a small area, you can use either vinegar or bleach mixed with water to remove it. Larger areas of mold should be left to the professionals, though. It's also a good idea to leave mold removal to the pros if you are sensitive to mold or have asthma. </p></div>

Q: What if my air conditioner isn't cooling?

• <div><p>Most units are designed only to cool the house down to 20 degrees less than the temperature outside. This means that if it&rsquo;s 99 degrees Fahrenheit out and you&rsquo;re trying to cool your home down to 65 degrees, you&rsquo;ll notice your AC is struggling. </p><p>Lower the blinds on all your windows, turn on your ceiling fans, and keep the thermostat at a consistent temperature to help your AC do its job. Investing in an <a href="https://www.angi.com/articles/hvac-service-contracts-waste-money.htm">HVAC maintenance plan</a> also helps because pros will come out to inspect and tune up your unit regularly, keeping it in optimal working condition.</p></div>

Q: Is it okay to clean an AC filter with water?

• <div><p>For washable or electrostatic air conditioner filters, you can soak and rinse them with water. If you rinse the filter with water, make sure to use a faucet, shower head, or garden hose with a gentle water pressure setting, as strong water pressure could damage the filter.</p><p>But for disposable filters, water could ruin the filter, even allowing mold to grow in the filter. Instead, these filters should be replaced.</p></div>

"I'm very happy with the work performed by this company plus the technician explained to me in detail of the work he was going to do as well as the correct way the dryer vent should have been installed before as the the exhaust vent was connected to the lower vent instead of the higher vent, saying that connecting it to the higher vent gave it more room for the lint to collect before it started clogging up the exhaust. The air duct cleaning was also conducted professionally and I have no complaint about their work. I would hire them again the next time my heating and cooling ducts needs cleaning. I'd recommend them to my friends."
