Q: Are AC units with a lower SEER rating being phased out?

• <div><p>The DOE is phasing out AC units with SEER ratings that fall below 14 or 15. The exact minimum rating depends on your region. In the northern United States, new ACs must have a minimum SEER rating of 14, though you can still buy and install older systems as long as they were compliant when they were manufactured. In the southern and southwestern United States, you cannot buy or install older air conditioners with lower SEER ratings. The minimum rating is between 14.5 and 15, depending on the power of the unit.</p></div>

Q: Is it OK to run the AC and dehumidifier together?

• <div><p>Yes, a dehumidifier and air conditioner can be used simultaneously in a home. A dehumidifier can bolster an air conditioner&rsquo;s efficiency. Typically, a dehumidifier is used when the air conditioner alone cannot keep a home&rsquo;s humidity levels at a comfortable <a href="https://www.angi.com/articles/maintain-whole-house-humidifier-summer.htm">indoor humidity</a> level, which should, ideally, be between 30% and 50%.</p></div>

Q: Why is my AC running, but no cool air is coming out?

• <div><p>There are a few reasons your AC is running but not cooling your room. Thermostat issues and dust and debris, which can clog your system, are common problems. It could also be a broken component, such as a compressor, blower fan, or evaporator coils. You&rsquo;ll need to call a pro to diagnose the issue.</p></div>

Q: Is HVAC the same as AC?

• <div><p>No. HVAC, which stands for heating, ventilation, and air conditioning, includes all of the systems that work together to regulate a building&rsquo;s temperature and humidity levels. In comparison, air conditioners only provide cooling. You can have an air conditioner as part of your HVAC system, but not all HVAC systems include air conditioners. </p></div>

Q: How do you remove mold from an air conditioner?

• <div><p>You may be able to <a href="https://www.angi.com/articles/how-rid-your-ac-mold-and-more.htm">clean mold from your air conditioner</a> in some cases. If the mold growth only takes up a small area, you can use either vinegar or bleach mixed with water to remove it. Larger areas of mold should be left to the professionals, though. It's also a good idea to leave mold removal to the pros if you are sensitive to mold or have asthma. </p></div>

My Mitsubishi Mini split A/C was not cooling properly even after a tune-up by another tech company in the spring. Kevin came by the day after I called and fixed the issue quickly. Now the unit is like brand new. I would recommend and will have this business tune my units up from now on.

"Freedom Air Mechanical did an amazing job with replacing my boiler. I had 5-6 people come out to give me opinions and Craig was the only one that really took his time to help me find the best boiler for my home. He was very responsive, answer all my questions and concerns, and very importantly I knew he was honest. Out of all the potentials companies I considered, Freedom Air was the only one that gave me options and tried to help me save where I could. I would recommend Freedom Air Mechanical to my family and friends all day."
