Q: Should a whole house dehumidifier run all the time?

• <div><p>You should only run your dehumidifier in warmer months, such as spring and summer, to get the best performance out of your system. The air gets drier when temperatures drop in the winter months, creating less of a need for a dehumidifier. However, when to run a dehumidifier will depend on your local climate.</p></div>

Q: How long should AC stay off between cycles?

• <div><p>The length of an AC cycle depends on the settings in your thermostat and the unit you have. Central AC doesn't constantly run at full blast the way that a window unit does. A cooling cycle in most homes is 15 to 20 minutes. Then, the unit stays off for seven to 10 minutes to circulate the cold air in the house before the cycle repeats. It should repeat two or three times per hour. A short cycle lasts less than 10 minutes and then turns off.</p></div>

Q: Should I turn my AC off sometimes?

• <div><p>Yes, it&rsquo;s important to turn off your AC sometimes to give it a break and prevent it from freezing up. If your <a href="https://www.angi.com/articles/why-does-my-air-conditioner-run-constantly.htm">AC runs all the time</a>, your system&rsquo;s parts will wear down quicker, which may mean that you need to replace it sooner. Plus, using your AC constantly uses more electricity and leads to higher energy bills. </p></div>

Q: How long does an HVAC surge protector last?

• <div><p>Most HVAC surge protectors last about <b>three to five years</b>, depending on how often your home experiences blackouts or brownouts. If your unit is susceptible to more frequent electrical surges, consider replacing your surge protector every two years. Consult your HVAC professional to determine when and how often to replace your HVAC surge protectors.</p></div>

Q: Does my home need return air vents?

• <div><p>Yes. Return air vents are responsible for gathering and pulling in the warmer air. Once they draw it in, your system conditions the air by removing the warmer molecules from it, allowing your air conditioner to dispense the cooler air back into your home. Not only does this create a more comfortable environment for you, but it also keeps your air conditioner from overworking, resulting in lower energy bills. </p></div>
