"Called Josh on a Saturday morning to report a problem with our heat pump by noon he was here and had identified the problem. We are very happy with this company as they do not use a 1000% markup on parts like some HVAC companies in the area seem to charge. With Air Adviser you get Honest service at an Honest price."

"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."

Heating and Air Conditioning questions, answered by experts

Yes, a frozen AC unit can affect your indoor air quality since the reduced airflow won't be as effective at removing air pollutants, like dust and other allergens. Additionally, ice around the unit can create excess moisture, leading to mold and mildew that can damage your home if you don’t catch it early.

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.

Troubleshooting common issues with your AC often sheds light on a problem with the compressor. Signs that you need to replace a bad compressor include your AC blowing warm air, short cycling (turning on and off), making strange noises, and blowing less air overall. Since these problems can stem from several areas of your AC, always call a local AC repair team to confirm it's the compressor.

Most units are designed only to cool the house down to 20 degrees less than the temperature outside. This means that if it’s 99 degrees Fahrenheit out and you’re trying to cool your home down to 65 degrees, you’ll notice your AC is struggling. 

Lower the blinds on all your windows, turn on your ceiling fans, and keep the thermostat at a consistent temperature to help your AC do its job. Investing in an HVAC maintenance plan also helps because pros will come out to inspect and tune up your unit regularly, keeping it in optimal working condition.

Ceiling fans can be a great way to cool your home without the expensive utility bill of running an air conditioner. Plus, ceiling fans can sometimes run in both directions, pushing hot air down in winter and pulling cold air up in summer. With that said, air conditioning might be the only thing that helps if you live in a very warm climate.
