Q: How often do AC coils need to be replaced?

• <div><p>Evaporator coils last between 10 and 15 years before they need to be replaced&mdash;as long as you stay up-to-date with routine maintenance. This is roughly the same life span as most AC units. So, if you have an older air conditioner and the evaporator coil goes out, it might be more cost-effective to replace the whole unit rather than just the coil.</p></div>

Q: 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&rsquo;s indicated with an &ldquo;R&rdquo; code. It&rsquo;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>

Q: How often should I change my HVAC air filters?

• <div><p>It's recommended to change HVAC air filters every one to three months. The frequency depends on factors such as filter type, indoor air quality, and whether there are pets or people with allergies in the household. Regular filter changes maintain proper airflow, improve indoor air quality, and ensure efficient HVAC system operation.</p></div>

Q: How do I reset my air conditioner?

• <div><p>To reset your air conditioner, start by turning it off at the thermostat. Then, shut off power to the AC system at the circuit breaker. Next, find the &ldquo;reset&rdquo; button on your AC unit and hold it for three to five seconds. The unit should beep several times. If your air conditioner doesn&rsquo;t have a reset button, leave the circuit breaker off for 30 minutes. Afterward, turn the power back on at the breaker and program the thermostat to &ldquo;cool&rdquo; to test the system.</p></div>

Q: Who sets the guidelines for air changes per hour?

• <div><p>The American Society of Heating, Refrigerating, and Air-Conditioning Engineers, or ASHRAE, sets the standard guidelines for air changes per hour in homes and businesses. The International Residential Code, or IRC, also sets ACH requirements for residences and bases those requirements off of ASHRAE standards plus climate specifics related to your location. </p></div>

We are very pleased with the work he did. He replaced an old dryer venting line that had completely broken down and was putting a lot of lint out into the inside of our home. It so nice to run the dryer now and not have all that hot moist air and lint going everywhere. Thanks Van
