"We had been told by another company the unit needed to be replaced. Shoals did a diagnostic and completed the work for 1/10th of the other estimated cost. They were fast, courteous, on time, and professional. I was having this work done for a family member who is in the hospital. I believe the other company was trying to take advantage. I would recommend Shoals Comfort Solutions LLC to anyone looking for honest-professional service."

"Mr. Ferrell first connected his computer to my computer via internet and worked for quite a few hours trying to determine what exactly was wrong. The next day he continued working from his computer for several hours. He determined he would have to have my desktop tower to complete the repair. He and my son met in Huntsville to exchange the tower. He then cleaned up a lot of what was wrong and reloaded Windows 10. He deleted the D: drive which had way too much memory allotted to it. The tower was returned and I plugged it all back together and it is working better than it did when I first purchased it. I would use him again and I recommend him highly to anyone needing computer updating and/or repair. His work is warrantied and he is very personable, knowledgeable, and helpful."

Air Conditioning FAQs, answered by experts

If left untreated, a frozen AC unit can lead to costly damage, especially to the compressor and evaporator coils. When ice forms on the evaporator coils, they become brittle and more susceptible to breaking. Plus, a freeze makes your AC system much less efficient, which means it's wasting energy and costing you more in your monthly energy bills.

Mold in your air conditioner isn't a good thing, as it can be harmful to your health. If the mold travels through the ductwork or is blown out of the A/C, you and your family can inhale mold spores and develop respiratory illnesses and other problems. Preventing mold from growing in the air conditioner will help protect your health.

Most HVAC surge protectors last about three to five years, depending on how often your home experiences blackouts or brownouts. If your unit is susceptible to more frequent electrical surges, consider replacing your surge protector every two years. Consult your HVAC professional to determine when and how often to replace your HVAC surge protectors.

Yes, adding central air can increase your home value by as much as 10%. Generally speaking, prospective buyers prefer a central AC system over a ductless system or room-by-room AC units. That’s because central air conditioning blends into the home easier than individual room air conditioners and typically has less equipment to maintain.

If your whole house is cold that’s one thing, but what if you only have a few rooms that are cold? First, you need to determine why this may be happening. A good place to start is to investigate the potential causes listed in this article—heat transfer, airflow, thermostat problems, humidity, and insulation. Once you’ve narrowed down the issue, you’d apply the same principles to the cold rooms as you would to the entire home.
