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: Does flex duct reduce airflow?

• <div><p>When first installed, flex ducts shouldn&rsquo;t cause airflow problems in your home. However, because flex ducts aren&rsquo;t the sturdiest and require extra support, they lose their durability over time and begin to sag, which can inhibit airflow down the road. Also, if your flex ducts aren&rsquo;t tight enough, your HVAC could work twice as hard for the same air pressure. If you&rsquo;re worried about the airflow in your home, a rigid duct may be your best bet.</p></div>

Q: Can a frozen evaporator coil cause damage?

• <div><p>A frozen coil can cause permanent damage to your HVAC system and lead to costly repairs if not fixed. It can cause the unit to overheat and also cause the compressor to fail. It&rsquo;s vital to turn the unit off if the coil is frozen and address the issue as soon as possible. </p></div>

Q: How many watts does an AC use?

• <div><p>An <a href="https://www.angi.com/articles/how-many-watts-ac.htm">air conditioner&rsquo;s watt usage</a> depends on multiple factors, including the type of AC unit, its size, and how often you use it. With that said, most central air conditioners consume between 3,000 and 3,500 watts. Meanwhile, window AC units use 900 to 1,400 watts, and portable air conditioners consume 2,900 to 4,100 watts. </p></div>

Q: Should I worry about my AC unit getting rained on?

• <div><p>The outdoor portions of air conditioners are designed to weather the rain, so you don&rsquo;t need to worry about it. An awning or roof will help protect them from snow or falling debris, which can do more damage. This is true of both window AC and outdoor units for larger systems.</p></div>

"We recently replaced our Heating & Cooling system with a energy efficient furnace & air-conditioning unit. We knew what we wanted, so I received bids from 4 different suppliers, receiving bids for a apples to apples comparison. All-Temp was by far the best pricing. Our installation process went flawlessly & the installers answered any question that I had. They came back out to our home per my request on a couple more occasions, to adjust the amount of time the 2 stage system ran. Everyone that we have dealt with has been extremely professional, courteous & knowledgeable. We just received a clean & check of our system & Jen our technician met each of those attributes. I would highly recommend All-Temp for any of your heating or cooling needs. Herb Pitzman Huntley, IL"

They removed the existing system and were great about not destroying our landscape. We had them install the new system in a new location, away from the back patio. So far everything seems to be running fine and I would happily recommend them to anyone."
