How can you tell if you have leaky ducts?

• <div><p>Higher energy bills, excessive dust, and uneven temperature are all <a href="https://www.angi.com/articles/signs-of-bad-ductwork.htm">signs of bad ductwork</a> or air leaks.

Q: What happens if you don’t clean an evaporator coil?

• <div><p>If you don&rsquo;t clean an evaporator coil, you&rsquo;ll likely experience many unpleasant results, including higher energy bills, mold and mildew buildup, ice or frost buildup, a clogged condensate drain, and more. In addition, you&rsquo;ll be dealing with an overall uncomfortable home and frequent HVAC breakdowns, plus your HVAC will continue to perform inefficiently. </p></div>

Q: Do vent air deflectors work?

• <div><p>Yes, vent deflectors do work to redirect hot and cold air distributed from your HVAC system. If installed correctly&mdash;and magnetic deflectors make it easy to DIY&mdash; you might find that a deflector is enough to redirect the warm or cool air where you prefer it to be. At the very least, it&rsquo;s an easy, inexpensive experiment before committing to the bigger project of moving the air vent to a new location.</p></div>

Q: How do I locate where the smell is coming from?

• <div><p>While a professional can always help, there are some common plumbing culprits you can check yourself to see if you can find the sewer gas smell. For example, you should check your water traps, sometimes called P-traps and S-traps, which are located under sink, shower, and laundry drains. The wax ring beneath the base of your toilet, which creates a watertight seal with the plumbing, could also have gone bad.</p></div>

Q: How frequently should I clean my air vents?

• <div><p>You&rsquo;ll want to spot-clean your air vents once every month. Spot-clean them by using a handheld vacuum, a brush attachment, or a microfiber cloth dipped in warm, soapy water. Make sure you trace over the corners and crevices, which trap dust. Once or twice a year, you should also deep clean. You can remove the vents and soak them in warm, soapy water for a half hour before cleaning, drying, and returning them.</p></div>
