Q: Can heat pumps cool a house in over 100-degree weather?

• <div><p>Yesh, heat pumps can easily cool homes when the weather reaches over 100 degrees Fahrenheit, just as powerful air conditioners can. The key is sizing the heat pump correctly for the size of your home and your climate. A local heat pump professional can help you determine the right size and type for your home. </p></div>

Q: Do return ducts need dampers?

• <div><p>If you know <a href="https://www.angi.com/articles/how-to-identify-supply-and-return-ducts.htm">how to identify supply and return ducts</a>, you&rsquo;ll find that only the supply ducts will have dampers. Although your return ducts can have dampers, it&rsquo;s not common. If you have one return duct that is pulling in too much air, adding a damper to it can help with overall system performance. However, dampers on return ducts are not a necessary addition for most homes.</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>

Q: Should I install a ceiling fan or an air conditioner?

• <div><p>Ceiling fans can be a great way to cool your home without the expensive utility bill of running an air conditioner. Plus, ceiling fans can sometimes run in both directions, pushing hot air down in winter and pulling cold air up in summer. With that said, air conditioning might be the only thing that helps if you live in a very warm climate.</p></div>

Q: What is the AC unit on the roof called?

• <div><p>If you&rsquo;re shopping around for a rooftop AC unit, you may hear them referred to as &ldquo;package units.&rdquo; That&rsquo;s because rooftop AC systems are all-in-one heating and cooling units that connect directly to your home&rsquo;s ductwork. If your AC repair pro references a package unit, they are referring to the system on your roof.</p></div>

"Had new hvac, furnace, and hwh installed. Furnace had a couple of air leaks between a coil and furnace which I fixed myself. Hvac was spot on. Hwh failed first inspection, but was corrected in same day. For the premium price paid, these issues should not happen. Quality 4.5 because of these issues, same goes for value. Customer service is very good. They are very professional, work looks very good, clean worksite afterwards. I would recommend, but don't think about negotiating price with them. Their labor is very high."
