I purchased a deal for air duct cleaning for $89 (valued at $350). It took 1 month to get an appointment, which was not a problem since this was no emergency. The guys were on time, polite and overall very professional. I was very satisfied with the work. 

Unfortunately the "creative" (if not deceptive) wording of the deal and the up sale made it a $300 job. OK, I did agree to the additional duct "chemical" treatment but be aware that those deals most likely do not cover the cleaning of whole system. In my place is small (1st fl, condo, ~1000 sq ft.), the supply line is exactly the same size as the return line, as it turned out, the return was not covered by the deal and I had to pay the regular price of $89 for it. The funny thing is that I supposedly got a "deal" valued at $350 for the supply line and vent only... How can the deal be valued at $350 if cleaning the exact same surface (return main and vents) was $89.

So, get a quote for your specific system before buying any deals, if you like the price, you can trust the technicians to do a good job.

*** I have recently added the Nashville area to my service coverage. Since I can do most of my services remotely with you over the phone, I am hoping to eventually open up to larger markets and help people from having to take their computer in to get it fixed, if it has internet access, I can usually fix it over the Internet. Just trying to do more to help my Angies List customers!!******** I am a sole proprietor that works out of my home. I am my only employee, but I have over 20 years experience fixing computers, and providing superior customer service. I work on a flat rate service, and don't charge by the hour because I feel it's important to educate the customer on what the issue is/was, and how to avoid it in the future. I feel that local service companies (my competition) have been overcharging customers for years. I offer a first time customer discount of 10% but I will offer 15% off for first time customers referred by Angies List. I've lived in the Huntsville area most all my life, so I know the area very well. I will never use a subcontractor as I am very picky about making sure that if my name and company is associated with something, it will be the best experience my customer has ever had, and using sub contractors won't ensure that, so I prefer to do all the work myself. Lastly, I should point out that I am a former offensive lineman for the University of Southern Mississippi and was Brett Favre's center his freshman year at Southern. I went on to play for Tom Landry in his last year, but gave up pro football early on to pursue my passion of fixing computers. If I didn't have bills to pay, I would do this for free because I love it! If you have a computer problem, I promise you that you couldn't find a better technician that will care about you as a customer, and not about the bottom line. I am always available, but don't always answer my phone, but if you leave a message, I promise to back with you as soon as possible...and figure out how to get your issue resolved in a quick, efficient and economical manner. Thanks so much for reading my ad, and I look forward to working for you!

"American Home Shield does not do repair work; they subcontract it. If replacement of anything more than very minor parts is required the subcontractor must obtain their approval and usually order parts from an approved supplier. This can cause some repairs to take several days. In this case the HVAC subcontractor was superb. He quickly inspected the entire furnace and identified and explained the cause of the problem.  Since there were no major parts requiring replacement he quickly completed the repair and no further problems have been noted.

Heating and Air Conditioning questions, answered by experts

Set your house temperature between 55 and 85 degrees Fahrenheit while on vacation, depending on the season. If it’s winter, don’t go below 55 degrees. In the summer, the best AC temperature for energy savings is no higher than 85 degrees. You can save anywhere from 10% to 15% on your energy costs by adjusting the temperature while you’re away. If you have a smart thermostat, set up vacation modes for each season. On your way home, turn off vacation mode to allow the home to warm up or cool down before you arrive.

You may never need an AC recharge if there are no leaks. However, if your AC unit has a leak that cannot be patched appropriately, you’ll need an AC recharge every time the freon level drops low enough that it disrupts your system—this could be once every two to three years. It all depends on the size and frequency of the leak.

Most HVAC service calls include diagnostic fees, which could include checking on a specific issue you’re experiencing or running through a routine inspection checklist. If you called for a particular problem, the service call will also include an estimate to fix the issue, including materials and labor. Depending on your HVAC technician and the service you requested, you might also get a general inspection of your system components to ensure everything is working as intended.

Here’s the cost formula to find out how much it’ll cost you to run a window air conditioner in your home:  Watts * (hours used) / 1,000 * (Local kWh) = daily cost of running a window unit. If you need help calculating the cost of running your window AC unit, consult an AC repair or installation pro for an accurate estimate.

To diagnose a bad HVAC or AC damper, assess the airflow from your vents. For a manual damper, close it, run your system, and check for airflow. If air is still coming through the vents, the damper is likely faulty and needs repair or replacement. For an automatic damper, turn on your HVAC system and monitor the airflow and room temperature. Signs of a problem include low airflow, a room that won't maintain its set temperature, or a drafty feeling. If you suspect a faulty automatic damper, you may need to hire a professional for repairs.
