"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."

"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

Water buildup in your HVAC system is a cause for alarm. If water accumulates in your ductwork, it can drastically lower your home's air quality and create safety hazards. These risks include mold growth, damage to your HVAC system, and attracting pests that are seeking water into your ducts. Proper insulation and sealing of ducts can prevent this, and regular inspection and maintenance can address water damage problems before they become too severe.

Yes, running your air conditioning unit too cold can cause condensation in the air ducts and built up moisture on the air filter, resulting in a breeding ground for mold and mildew. Mold and mildew growth can irritate those with respiratory issues, so it’s best to keep your AC running at a normal temperature.

Choosing a unit with higher BTUs can use more electricity if the BTUs are more than what’s necessary for your room size. However, choosing an AC with BTUs that match the size of your room or house, your unit will cool your space efficiently. On the flip side, choosing a system with not enough BTUs can cause the system to work harder to try to cool the space, leading to more electricity consumption and higher energy bills.

The general rule of thumb for figuring out how much AC tonnage you need in your home is that for every 500 to 600 square feet of space you need to cool, you’ll need one ton of AC cooling power. So, a 1,000-square-foot home will need 2 tons of AC power. 

NATE (North American Technician Excellence) certification is not legally required for HVAC technicians in most areas, but hiring a professional with this certification is highly recommended. NATE-certified technicians demonstrated their expertise and proficiency in different types of HVAC systems, offering assurance of quality service. It's a voluntary certification, yet it indicates a commitment to professionalism and ongoing training. Choosing a NATE-certified technician often means you're working with someone who is up-to-date on industry standards and best practices, which can lead to better service, energy efficiency, and long-term cost savings.
