"ECC is AWESOME!! From talking with Lisa, who scheduled EVERYTHING!! to Ed the gentleman who came out and estimated the job, to Tony, his son and Jane (the installers) everything was seamless!! The communication was EXCELLENT!! Lisa is excellent at keeping me informed about the process and following up when things were done. I can’t say enough about Tony and his crew!! He went above and beyond my expectations! He even RE-routed a condensation pipe to the gutter so it wouldn’t keep dripping onto my shingles!! Just an amazing company!! Would ( and have) recommend them to everyone I know for their HVAC needs"

"Adam and Nate were very prompt, polite and thorough. They replaced the two hvac systems at my home. They worked quietly and cleaned up after themselves. They provided me the best bid with the lowest cost and the earliest delivery time and they delivered. The job was done on time and on budget. I would definitely use AAC again."

"We have a yearly maintenance agreement with them after they installed our air conditioner. They're very efficient. They come when they say they're going to come and do their work. The last time they were here for AC, they did find a problem and fixed it at no charge."

"Had an amazing experience! This was the second time using this company and again I was not disappointed!! The guys showed up on time, were very professional. Explained what they were going to do. Since I had just bought a new house and the vents were so dirty they said they would like to use a disinfectant. It’s very nice to have piece of mind knowing that my air and dryer vents are nice and clean! I would definitely recommend them."

Heating and Air Conditioning questions, answered by experts

Yes. It's not just AC filters that get dirty. Ducts can accumulate dust and dirt quickly. Insects and animals can also get into duct systems, creating many problems. Dirt build-up and unwanted guests can constrict the airflow and cause rooms not to cool evenly. You might also see higher energy bills because they're not working as efficiently.

Fixing a leak in an AC unit costs $200 to $1,600, depending on the type of leak and any related damage. But depending on the age and condition of your AC, it might make more sense to replace the AC unit instead of repairing it. If your AC is only a few years old and relatively problem-free, then repairing it is the right call. But if it’s nearing a decade old and has other issues, consider replacing it.

You will enjoy greater energy efficiency and save on your annual energy bills, with new, modern HVAC systems using 30% to 50% less energy than older models. Upgrading your HVAC system is also a great way to embrace new technology, such as smart thermostats, lighting, fan speed, and humidity from your phone or tablet.

One of the fastest ways to unfreeze an AC unit is to turn off the unit and, if it’s warm outside, use the fan-only mode to help blow warmer air through the unit to speed up the defrosting process. While it may be tempting to use a hair dryer to defrost the air conditioner, that high heat can damage the coils.

After defrosting, if you can safely solve the issue with a fix like changing the filter, go ahead and do so. Otherwise, call in a pro before turning your AC back on.

Yes. It's normal for the AC compressor to cycle on and off intermittently in dry mode as it maintains the desired humidity level. The compressor cycles to prevent over-dehumidification and to maintain a comfortable indoor environment. This cycling behavior ensures efficient operation and optimal humidity control, contributing to the overall effectiveness of the dry mode function in your AC system.
