Q: Can central air be added to an existing furnace?

• <div><p>If your home has an existing forced-air heat system, you can add a central air conditioner to it. An HVAC technician can retrofit your forced-air heating system by installing an evaporator coil onto the furnace plenum, the box next to the furnace that draws in air. Once installed, the air conditioning coils use the furnace&rsquo;s blower to circulate the air.</p></div>

Q: Where can I buy R-22 Freon for my home AC?

• <div><p>You can buy R-22 refrigerant for your home air-conditioning system through your <a href="https://www.angi.com/nearme/air-conditioning-repair/">local AC repair specialist</a>, who can also refill your R-22 system as needed. You may find that the cost of R-22 has gone up due to shortages as the EPA banned this refrigerant. Ask your pro to inspect your system for any leaks or issues.</p></div>

Q: Is an HVAC compressor covered under warranty?

• <div><p>Many HVAC manufacturers provide warranties that encompass the cost of a new compressor, with durations ranging from 5 to 10 years, depending on the brand. These warranties cover critical components such as the compressor, condenser, connecting tubing, evaporator, and refrigerant charge. Moreover, they often include the necessary labor for replacement or repairs. Keep in mind that premium-brand compressors may offer lifetime warranty options. It's essential to note that these warranties rarely cover labor costs.</p></div>

Q: Is it OK for my AC to run all day?

• <div><p>If you have central air conditioning, it&rsquo;s fine to <a href="https://www.angi.com/articles/how-long-ac-can-run-continuously.htm">run your AC all day</a> if that&rsquo;s what you want&mdash;as long as the AC unit is in good condition. But if your AC runs constantly when you don&rsquo;t want it to, there may be a problem with your system (like the ones we&rsquo;ve mentioned above). Window AC units and wall air conditioners aren&rsquo;t as powerful as central AC, so you should only run those kinds of air conditioners for eight to 12 hours at a time. </p></div>

Q: What happens if you don't clean your AC evaporator coils?

• <div><p>If you don't clean your AC evaporator coils, dirt and debris will build up, which impairs the system's ability to transfer heat. This forces the unit to work harder, leading to inefficient performance, higher energy bills, and frequent breakdowns. Over time, neglected coils can corrode, which may cause refrigerant leaks, or develop mold, ice buildup, and a clogged condensate drain, resulting in poor air quality and an uncomfortable home.</p></div>
