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

thumb Joseph Gajda

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.

thumb Lisa

thumb Melissa Friesl

Just had Bart and his team come out to clean furnace and air vents on 2/26/19. I Highly recommend Excellent HVAC. They were very professional and a great price too! I couldn't believe how dusty and dirty the vents were, I feel so much better knowing that my vents were cleaned professionally. See you in two years!

thumb Eduardo Canedo

👍🏼👍🏼I recommend Excellent HVAC! We had all the ducts cleaned in the house we recently purchased which has probably never been cleaned before. Bart had his work cut out for him but was up for the challenge and did a great job.

thumb Trevor Martin

Good job and good price. They communicated the details and cost and the final price did not change from the estimate. They sent two advisories of their arrival time. Recommended.

thumb Anthony Facchini

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.

thumb Harry Marcado

thumb tim m

We can’t say enough how professional, courteous, clean and responsive they are. I checked with a lot of other companies but they were the best price and the company was very helpful. They installed a new ac/furnace combo. Really professional guys. Highly recommended to all.

thumb Jozef Janecko

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.

thumb Tanya Z

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!

thumb Dennis Harrison (RaySun2Be)

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.

thumb Andres J. DeLeon

Woke up this morning in the freezing cold to find out my furnace wasn't working (and this old house doesn't stay warm long)! Filter was fine and pipes were unclogged, but the heat just wouldn't stay on. Bart knows his stuff! He had it up and running in no time - Excellent! Now I know who to call when this system inevitably needs some fixing up

thumb Jake Frantz

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
