Can an evaporator coil work with any refrigerant?

• <div><p>No. Evaporator coils are designed to work with specific refrigerant types, and they are rated by what kinds of refrigerant they use. It’s indicated with an “R” code. It’s important to match your evaporator coil and refrigerant or your system will not work properly. An AC technician can tell you what type of refrigerant your system needs and what evaporator coils will work with it.</p></div>

Is it better to repair an AC or buy a new one?

• <div><p>There are a few factors to consider if you’re deciding between <a href="https://www.angi.com/articles/it-time-repair-or-replace-my-air-conditioner.htm">repairing and replacing your air conditioner</a>. It’s probably worth fixing the AC unit if it’s less than 10 years old, you’re dealing with a one-off issue, and your warranty or maintenance plan will cover the repairs. On the other hand, if your air conditioner is dated, inefficient, out of warranty, and experiencing multiple problems, consider replacing it.</p></div>

How often do HVAC systems need maintenance?

• <div><p>You should have your HVAC serviced at least <b>once per year</b>. A HVAC pro can perform maintenance twice a year if your unit is older or has many issues. You can expect to pay between <b>$100 and $550</b> for <a href="https://www.angi.com/articles/ac-service-cost.htm">HVAC maintenance</a>, which includes a thorough tune-up, routine service, proactive and reactive maintenance, and emergency maintenance services. </p></div>
