I decided to go with Herchenbach Mechanical after comparing a couple other places in the area. Scheduling an appointment was easy. Curtis and his team came over and installed the AC unit fairly quickly. They were very professional and courteous. Fast forward to a few days ago, my kid decided to throw pieces of chalk down the pipes. I called Herchenbach Mechanical to schedule a time and date that works for me. They will email and text you to confirm your appointment. On the day of your appointment, they will also send you a photo of the technician that will be over. Adam, the technician, was very friendly, knowledgeable, respectful and on time. I told him what happened and he explained what he would need to do to get the chalk out from the pipes. I also scheduled them to clean my AC as well. After Adam finished using the hose from the backyard, everything was neatly put back the way it was. He didn't leave anything out or left a mess. When he was inside the house, he would immediately put on those disposable shoe covers without me having to ask. Herchenbach Mechanical has always provided great, friendly service when I needed them. I have nothing but good things to say about Curtis and his team. Again, highly recommend them! You won't be disappointed.

Highly recommended.

He and encouraged me to call after the 'furnace' season returns to report whether I still hear the noise. He is very personal, friendly, and conscientious. I will call him again if I have another problem.

I decided to give Dana Heating a chance & I'm so happy I did! The previous company was charging monies & as I found out through using Dana that company didn't do what they were suppose to do & that's maintain the furnace. That company quoted me prices & parts I didn't need (5 yr old furnace they installed). I appreciate transparency & honesty in which Mike from Dana Heating provided. He was very nice, professional, & showed me everything that needed servicing which was the basic maintenance tune up. I'm glad to have hired them & definitely will hire them again for future jobs while highly recommending them to everyone. Also they've been in business for over 35 years! That alone screams they know exactly what they're doing to stay in business this amount of time which speaks volumes! I appreciate a company that delivers true customer service without the cover-ups which lies inconsistencies just to fool the customer into purchasing items that's not needed. If you want a company that'll treat you with honesty & respect without breaking the bank give Dana Heating, Cooling & Supply a try!

Mr. Duct sent Miguel out to clean our ducts. He did a great job. For those looking at duct cleaning…read moreservices, you should look for National Air Duct Cleaners Association (NADCA) certified shops. You should also shop around because some places offer bonus services that you may or may not need, or may even be hazardous to the occupants of the home, like sealants or chemicals. Check the EPA page on "Should You Have the Air Ducts in Your Home Cleaned?" for a thorough treatment of the topic, though note that it's much less enthusiastic about duct cleaning than people's subjective experiences, especially people with allergies or sensitivities, or if you've just done a remodel. I'd refer to "Is it worth it to get your air ducts cleaned?" on r/homeowners and "Is air duct cleaning a scam?" on r/hvacadvice. With that out of the way, Miguel cleaned our ducts quite thoroughly. He inserted the vacuum to the air handling unit. This would provide the negative pressure to ensure most of the dust and debris would go to the vacuum. Then he use a air compressor to knock loose the dust at each register and as far into the ventilation as he could push the nozzle. My registers unfortunately went up towards the attic, so dust was guaranteed to get knocked loose into the room, so we had to vacuum. This would have gone smoother if Mr. Duct had sent a partner with Miguel. Miguel was also very helpful in airdropping the photos of the ducts to my phone, which was important because we were trying to identify what might be triggering allergic reactions. For roughly $300, it was very reasonable. I would recommend Mr. Duct to those who need duct cleaning services.
