Q: Is an AC unit with a higher SEER rating worth it?

• <div><p>If you&rsquo;re planning an AC replacement, choosing an AC with a higher SEER rating may save you money in the long run. Tax credits could cover as much as 30% of the job, and you&rsquo;ll notice smaller utility bills (particularly if you live in a hot climate where you need to constantly run the AC). Generally, you can expect to pay between <b>$350 and $1,500 </b>for each SEER rating increase. Weigh the cost against your typical utility bill to figure out what&rsquo;s worth it to you.</p></div>

Q: Are mini-splits cheaper to run than central air?

• <div><p>Yes, mini-split systems are generally less expensive to run than central air conditioners and are significantly more energy-efficient. Because mini-splits do not rely on ductwork, they avoid the energy loss associated with ducted systems, allowing cooled or heated air to reach its destination more efficiently. Additionally, they offer zoned control, meaning you can run units in individual rooms and turn them off in unoccupied areas. This capability can lead to energy savings of about 30% compared to a central air system, resulting in a lower monthly energy bill.</p></div>

Q: Is unfreezing your AC a DIY project?

• <div><p>Unfreezing an AC unit is not a DIY project unless the problem is a dirty air filter. Changing out an air filter is easy for homeowners, but otherwise, trying to repair ductwork, refill refrigerant, or replace a blower fan motor are tasks best left to the pros. Otherwise, you could cause further damage to your cooling system or even harm to yourself. </p></div>

Q: What does a bad AC sound like?

• <div><p>There are plenty of different not-so-great sounds to hear from your air conditioning unit, like squealing, grinding, water running, excessive gurgling, banging, and clanking. Each of these sounds can indicate a different malfunction with your unit, so it&rsquo;s important to have a professional assess the problem before it gets worse.</p></div>

Q: How do I measure duct CFM?

• <div><p>A calculation method that your HVAC contractor will use to ensure your system does what it's supposed to is measuring duct output, or its CFM. The calculation requires knowing the cross-sectional area of the ductwork and determining the air speed past any given point within it. </p></div>

"Called Oscar 6-16-14. Came out 6-17-14; accessed that the sewer pump had burned out; had brought a replacement with him. He and his assistant replaced it within half an hour. Charged $60 for service call and $30 for the half hour. $410 for the pump. Very genial and neat in their clean up. Would recommend.

"We own a home-based business which relies heavily on our computers operating efficiently. We have had a service contract with another computer repair business for several years. Recently when we were having problems with our computers, we tried contacting our service contractor multiple times. He never responded. Feeling frustrated, I contacted James at North Alabama Technical Services and explained our situation. He instantly came to our rescue. He "cleaned-up" our computers and took care of all the problems we were experiencing. He went above and beyond to help us in our dire time of need. We would strongly recommend James and his company for computer service needs. We have now retained him on a service contract and are looking forward to working with him in the future."
