"Great experience with Flame Tech. George was knowledgeable and responsive. He provided an accurate estimate over email based on a number of photos and a few phone conversations which streamlined the bid process considerably. They replaced my AC in a few hours for a fair price and educated me on other safety considerations related to my furnace. He also helped me diagnose a rattle in my air ducts that would have given me fits. Good price, know-how, and customer service, I would use Flame Tech again."

"Contact was made with Jason and he met with me for a free estimate of what work I wanted performed.. Jason and Chris were hired to service the Furnace and to install new H&A ducts underneath the house. Other work performed by the guys was replacing old and leaking waterlines underneath the house, and hauling away all the old ducts. Hauling an old Heating and Air unit on the side of the house, and doing some mason work to cover the hole. Installing a section of chain link fence and gate. Troubleshooting and replacing an electrical switch in the storage shed. Unclogging and replacing a waterline underneath my bathtub and installing a new shower head and fixtures. Also, repairing a leaking toilet bowl and replacing a rotting section of floor underneath..... Overall, the boys were excellent in their knowledge and work performance. They were easy to talk too and their work ethics was superb... I would without a doubt hire them again should and when the need arise..."

"Excellent service, very fast response to my request for service, picked up laptop, diagnosed issues. Initially thought it was an OS update issue but the hard drive had failed along with other components (including 'CPU). Because other components were involved, a new solid state hard drive was put into a laptop with a working processor - same type CPU as in the failed unit. The laptop was repaired and returned in less than a week. This company picked up and dropped off the laptop (driving from Huntsville, AL (about 60-70 minutes)-- great service in this covid environment. I would recommend this company to my family./friends and will use again."

Heating and Air Conditioning FAQs, answered by experts

Vents may blow air even though the air conditioning system is off because of the pressure difference between indoor and outdoor air or drafts from leaky ducts. Check for leaks or drafts in the ductwork or around windows and doors.

You can buy a new AC capacitor through most big-box home improvement stores, from an HVAC contractor, or from the manufacturer. Use the model number of your air conditioning unit to make sure you purchase the right part for your unit. Also, keep in mind that the cost of this type of part can vary significantly depending on who you purchase it from, so shop around to get the best price.

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.

When first installed, flex ducts shouldn’t cause airflow problems in your home. However, because flex ducts aren’t the sturdiest and require extra support, they lose their durability over time and begin to sag, which can inhibit airflow down the road. Also, if your flex ducts aren’t tight enough, your HVAC could work twice as hard for the same air pressure. If you’re worried about the airflow in your home, a rigid duct may be your best bet.

You may be able to clean mold from your air conditioner in some cases. If the mold growth only takes up a small area, you can use either vinegar or bleach mixed with water to remove it. Larger areas of mold should be left to the professionals, though. It's also a good idea to leave mold removal to the pros if you are sensitive to mold or have asthma.
