"Jim Farrell and North Alabama Technical Services rebuilt my computer and provided me with everything I expected and so much more.  He provided the various options in equipment, including specs and pricing, answered all our questions and helped us make the best decision for our purchases.  The computer was completed in a few days, far less than expected, the installation included clear directions for use.  The package also included a good warranty for the equipment.  I was extremely pleased with his service and would not hesitate to recommend his company to anyone with computer service needs."

"The blower motor on my furnace was squeeling, and not working at all most times.  When I spun the squirrel cage manually it would work for a short time, but then finally got to the point where it wasnt working at all.  Just a hummy noise.  When I called them, I left a message and within hours I got a call back.  I explained what I thought was wrong and they confirmed that it sounded like a bad blower motor, or to try the starter capacitor first.  I got a capacitor first and swapped out, but no luck.  Then got in touch with them again and within a hour got a new motor to swap out.   He was very easy going and said I could swap it out myself if I wanted and then if I had problems, to call them and they could come out.  I attempted the swap, but I could not get the squirrel cage off the old motor.  I called them the next day and they came out that same day and finished the work for me using the right tools.  Within a hour and a half, I was up and working again and have been working fine ever since.  a new blower motor and starting capacitor was changed.  I would recommend them in the future to anyone."

"The workers were polite and efficient. They sealed the area for work with plastic before I left. When I came home the furnace and ducts were gone. It took about 8 hours. They left no trace of their work behind. The price was a little higher than some other quotes, but well worth it for the professionalism.

"Well, the first time the replacement was ordered it was the wrong one, which of course, delayed the installation a week. When it was finally installed I had to pay an additional $850 for code upgrades. This I was not informed of by Home Shield. Then we noticed that there was water on the garage floor and found that the pipe coming in from the wall was leaking at the wall so had to call the plumbing company back out to fix it. They first tried to say it was not their fault but since there wasn't a leak before they installed they did fix it. I have used Home Shield a few times before and never had a problem. Some of the companies they use are not the best so you have to research them before you commit. I have found HS service to be good if you do your homework. At the end of the day I was without hot water for almost 3 weeks but it was do to the plumbing company they sent out."
