"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."

Heating and Air Conditioning FAQs, answered by experts

Window ACs use 500 to 1,400 watts per hour of electricity, while mini-splits use 500 to 700 watts per hour. However, if you need to cool multiple zones in your house, your mini-split can use as much as 2,000 watts per hour. How often you run your system will impact how much electricity you use (and how much you pay per month).

A new HVAC system can increase your home's value by about 5% to 7%, which can translate to an added value of $2,500 to $3,000. The return on investment (ROI) can be around 30%, especially if you upgrade the entire system, including ductwork and insulation. Adding modern features like a smart thermostat can further increase your home’s value by making the heating and cooling systems more efficient and convenient. However, since a new unit can cost $10,000 or more to install, it's important to weigh the upfront cost against the potential increase in home value. For a specific assessment, it's best to consult a local AC installer.

Yes. In fact, not only are AC tuneups worth it, but they’re actually necessary to keep your air conditioner in good condition, improve its efficiency, and potentially prevent major damage. Experts recommend getting a tuneup at least once per year. In most cases, you’ll want to schedule it during the spring so that you can address any issues before the hottest months of the year.

You can protect your air conditioner in the winter by turning off the power at the thermostat and performing routine HVAC maintenance in the spring. Regular maintenance, cleaning, and repair of your AC unit helps protect it and extend its life span. If you have a window AC unit, remove it from the window and store it in a dry place during the winter. Window units cannot withstand freezing temperatures. Keeping them in your window also allows cold air to seep into your home.

It depends on the type of AC unit and the extent of the mold growth. For example, if you have a small amount of mold in your central air conditioner, it’s worth cleaning it to protect your HVAC system and your health. In situations like these, you can often remove the mold yourself in a couple of hours. On the other hand, if you have a portable AC unit with a severe mold problem, it makes more sense to buy a new one. On average, replacing a portable AC unit costs $100 to $500.
