"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 questions, answered by experts

If your AC suddenly stops working, the first thing to check is your thermostat settings. Ensure the thermostat is set to the appropriate temperature and mode (cooling). Sometimes, a simple adjustment or replacing the batteries in the thermostat can resolve the issue. If that’s not the issue, look to see if the circuit breaker tripped. These basic checks can often identify simple fixes before you need to call for professional assistance.

The standard HVAC warranty is around five years. Still, many brands offer an extension to 10 years if you register the product within a specific timeframe, typically 60 to 90 days post-purchase or HVAC installation. Over the past decade, warranty periods have substantially increased, shifting from 3-5 years in the 90s to the now-prevalent 10+ year warranties. Both warranty types cover parts failing due to manufacturer defects, incurring no additional costs. Some manufacturers provide extended warranties surpassing the usual 15- to 20-year window, though these often involve extra fees. 

DIY is possible for basic cleaning. Professional services handle advanced maintenance like recharging the refrigerant.

Air conditioners can stop working in the middle of the night for many reasons. Your local power grid might shut down late at night. Power surges can also trip your breakers if too much power is being used in the area at the time. If your AC is connected to a digital thermostat, it gets naturally cooler at night, so the outdoor temperature might dip below the automated setting to turn the cooling system off.

You should only run your dehumidifier in warmer months, such as spring and summer, to get the best performance out of your system. The air gets drier when temperatures drop in the winter months, creating less of a need for a dehumidifier. However, when to run a dehumidifier will depend on your local climate.
