On time. Very thorough. True to estimate, even though it was probably more work than Bart expected. Previous home owner of 40 years probably never had ducts clean. Did a great job, great company.

I can’t say enough about the service this company provided. They arrived on time, extremely professional, very hard-working and extremely clean. They cleaned and vacuumed everything even though they were really was not a mess. They didn’t only do the vent cleaning but they also did a great job cleaning the actual furnace and sanitizing it. I was extremely impressed and would definitely recommend this company. I absolutely have nothing negative to say.

They did a very thorough job in cleaning out construction debris from our ducts after we had some work done on our home. It was done in a timely and very professional manner. They also gave us recommendations for maintenance of our air conditioning system after they cleaned our furnace. We highly recommend them for their great service!

I have used Bart in the past to clean my air ducts. I was so pleased with his work that when my furnace went out, I called him. He came over right away and fixed a couple things to bide me time. My furnace is 40 years old. He ended up needing to replace furnace within the next couple of days. He charged me a reasonable price and installed the furnace on Christmas Eve with no extra charge. He does a meticulous job, is very pleasant and professional. I highly recommend him.

My furnace stopped working this morning, on the coldest day of the year. They were quick to come out. After doing diagnostics, it required a part. Once they had the part, they came back installed the part, did maintenance to make sure the furnace is working at its best. They wore covers over their shoes, and cleaned up the work area afterwards. I highly recommend their services, and would use them again without hesitation!

We were in need of electrical work. Fenik’s Electric came out to price the electrical work which included setting up for moving an A/C unit. Excellent HVAC came out to price the move. Their price was equal to or less than a friend’s price. While pricing a new A/C they priced a combo replacing my 25 plus year old furnace. The price was super comfortable for seniors on a tight fixed income. On the 28th of March at about 8:00 AM until about 1:00 PM these two companies worked hand in hand to give me my electricity to my shed along with a HVAC unit that should work safely and efficiently saving me money on utility bills. I highly recommend to anyone.

Fantastic work! I wasn't entirely sure what was involved with duct cleaning for my 2 floor home. Excellent HVAC pulled up in a work van around 8:30AM. I could tell Bart and his co-worker were ready to work by the serious equipment they were pulling off the van. They prepped the room vents to ensure no debris would be flying all over the place or on my furniture. The only think I had to supply was an outlet, that was easy on my part. Then the magic started to happen once everything was connected. There was some air sweeping and rotary brush action going on. You can actually hear the years of junk in my air ducts being sucked away...LOL! Overall Excellent HVAC was super professional. They explained the process and answered my questions. Fast, friendly and a great price! Immediate and positive results in air flow was felt throughout the house once the A/C kicked in.

Great compan! First time I used Excellent HVAC Duct Cleaning a couple years ago when my A/C system stopped working. Unfortunately I had to install New A/C. They installed new cooling system at very reasonable price. Now I called the company again to service my heating system. Bartek, who is an owner, was on time and I was impressed with his professionalism. I have never seen another technician check the entire system so throughly before. I'm so happy that finally I have found a company I can trust.

Bart had the best price out of all the other reputable companies in the area. He also works very quick and his work is extremely neat. He added some duct work in my basement and was in and out in about an hour. I highly recommend and will contact him for future work

We are so pleased with the services we received from Excellent HVAC Duct Cleaning, Inc. My call to schedule a cleaning for the furnace/air ducts was answered by Bartlomiej Bilski, the owner, and an appt. was scheduled within days of my call. The team of Hector and Sergei were very professional and the process was well communicated. Before and after pictures were taken, it was astounding to see how dirty the ducts were and how clean they are now! While doing the maintenance they discover a broken humidifier within the furnace. I’m going to schedule that service with them. I am happy highly recommend Excellent HVAC for all your furnace needs.

lisa Warechowicz Avatar lisa Warechowicz

I had called four different local places for duct cleaning, and they all ended up being about the same price. Why did I choose these folks? They were easy to get ahold of, which is a big deal in this covid climate! Bart was easy to talk to, patiently answered all my questions, and was very knowledgeable. On the day of cleaning, the guys came on time and were kind and professional. We reviewed where all the vents were and they explained the process and timing. They even had a little vacuum to pick up any stray debris. I'm very happy with the work, would highly recommend them and will be using them again in the future.

We called Bart because our furnace and Ac system needed to be replaced. He came out same day to give us a quote.Bart and his crew were very professional and did a phenomenal job in our home. After air ducts were cleaned it smelled fresh and we are experiencing less allergies due to pet dander. Thank you Bart! We our glad we did business with you.

I highly recommend Excellent HVAC. They installed a new air conditioner unit at my business and also installed some duct work on existing units. They did a phenomenal job at a very fair price. I plan to use them again for any AC jobs I may have in the future.

Let me tell you something about Excellent Havoc first I am one of the most straight shooters you’ll ever hear from last few months I’ve been shopping around for a new furnace because I was having a lot of trouble with my old furnace excellent havoc had worked on my old furnace before they had the most compassionate helpful people you would ever deal with they explain things to you so you can understand them because most people don’t understand anything about heating and air-conditioning the owner Bart is a wonderful human being and so are the men that work under him I can’t express this anymore than I am now if you need any work on your furnace or need a new furnace please call Excellent Havoc they and the price was outstanding he didn’t hurt my pocket I got prices that were outrageous from different companies again Excellent Havoc that’s why they’re called excellent
