"Absolutely recommend DUCTZ to friends and family. They unclogged the dryer vent up to the roof and made sure to eliminated the cause of the fast clogging in my dryer vent. They didn't have to do that. Very happy with the price and the service so we will definitely use the service again."

"This is an excellent company. We have used them for year to service our heating and air conditioning units. It became necessary to think about replacing the units. We have two. Decided to replace both at the same time. They came out on a Monday and gave us an estimate and came out on Thursday and Friday to do the work. They totally cleaned up after themselves and made sure everything was working properly. Then they called a few days later to see that everything was working well. I highly recommend this company. All the technicians are polite and competent. The office staff is nice beyond belief. If you need any heating/AC work done, this is the company to do it."

"My air conditioning uni broke down during the heat wave (Wednesday, July 15th). I had no air for 4 days. Addis HVAC called me immediately after I requested service on Home Advisor (that was Thursday). The appointment was on a Friday, the price was right so we scheduled the installation to replace my HVAC system for Saturday. Adugna and his crew arrived promply Saturday morning, replaced my system and I had air by Saturday evening. Excellent service, the crew wore masks, gloves and foot coverings. I highly recommend this company."
