"There is no other way to describe my experience except outstanding and even enjoyable! Friendly honest realistic and so dang fast! I even threw another project at them as they were walking in the door. that was no problem they completed both projects I wanna say within two hours after leaving to go get parts. I never once felt intimidated or afraid that I was being cheated. There was something very reassuring; when your handyman tells you, that there is very little in my home they can’t fix. It is only fitting that Air Duct Man appears at the top of my contact list! Hire these guys! You will wind up feeling as good as I do!"

"Our overall experience with Honest Abes for our HVAC replacement went quite well. Equipment, techs, timing was all 5 star. My 4 star rating is for the contractor not providing the manufacturers warranty info. Honest Abes provided thier warranty but l wanted all the warranty info. I went to Goodmans site, entered all serial numbers and received all my data related to our HVAC system. It even list the built date of each item. If Honest Abes starts leaving the manufacturers warratny with their installs, l believe most customers would be more satisfied."

Heating and Air Conditioning FAQs, 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.

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.

Unfortunately, a freon leak will persist even when your AC unit is off. The freon in the AC unit is under pressure no matter the status of the system, so it will continue to drip through the leak even when you shut off the entire unit. It will continue to leak freon until it’s completely empty.

Whether an HVAC damper should be open or closed depends on the season, the zone it controls, and the temperature in that zone. In the summer, open upstairs dampers and close lower-level dampers to get the most efficient cooling possible. In the winter, do the opposite. Cool air will naturally flow down to lower levels, while warm air will rise. This keeps your system from working harder and helps prevent common AC problems.

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.
