Q: What happens when an AC compressor overheats?

• <div><p>When a compressor gets overheated in central air systems or heat pumps, it can still cool your home for a while until it eventually gives out. If the compressor is chronically overheated and no one addresses the root cause, it will create an incredibly expensive problem when your entire HVAC system breaks down and stops working altogether.</p></div>

Q: Can a whole-house dehumidifier save money?

• <div><p>Yes. Getting a whole-house dehumidifier can help you save money on energy bills. How? Your home automatically feels cooler when there&rsquo;s less humidity in the air (&ldquo;It&rsquo;s the humidity that gets ya!&rdquo; is such a true statement). This means that you won&rsquo;t need to run your AC as much as you would if you had all that extra humidity in your home.</p></div>

Q: Can a power outage damage your air conditioner?

• <div><p>A power outage can damage your air conditioner, just like a power surge can damage any electrical device or appliance. In most cases, your circuit breaker or built-in surge protection on your AC unit protects your AC and just needs a reset. But in other cases, it might be that your AC compressor or capacitor was blown during the power surge. You&rsquo;ll need to have an HVAC professional repair or replace any AC parts. </p></div>

Q: How can you extend your HVAC system’s lifespan?

• <div><p>To extend your HVAC system&rsquo;s lifespan, it&rsquo;s crucial to keep up with maintenance. This includes changing filters and thermostat batteries, keeping the outside unit clean and clear of clutter, and lubricating moving parts. Watch out for leaks, mold buildup, and blockages to ensure your unit stays in good working order. Spotting these issues early can be the difference between a simple, wallet-friendly repair and an expensive replacement.</p></div>

Q: Will low refrigerant cause a coil to freeze?

• <div><p>If refrigerant levels are low, it can cause the evaporator coil to freeze up. Low freon causes a drop in pressure, which will make the coil too cold and cause moisture to freeze on the coil. Your system may be <a href="https://www.angi.com/articles/does-freon-leak-mean-i-must-get-new-home-ac-unit-cant-i-just-get-leak-fixed.htm">low on refrigerant because of a leak</a>. </p><p>Make sure to have maintenance performed twice a year, and contact your local HVAC technician if you suspect your system has low freon levels. </p></div>
