I had a great experience with KNZ. Within a week I was able to get a quote and brand new AC installed. Everyone I interacted with was friendly, and I’d recommend them!

Nick and Zack were very professional and completed the installation flawlessly and in a timely manner!

“Had a problem with our furnace that was new in 2015, when the house was built..water was dripping out of the furnace..the furnace was not installed by KNZ, but we did not want the original installer..we called KNZ and the lady in the office said all the guys were out, but she would have someone stop at our home later that afternoon..We got a call from the repairman, and he said he was finishing on a service and would be over in about 30 minutes…About half hour later the serviceman showed up..he took our furnace apart and it seems it had been leaking for a while, as the parts were rusting..long story short, he repaired the leak, cleaned and checked the furnace and we’ve been good ever since..He was very neat with his work..cleaned everything up, and thanked us for giving them a call…KNZ gets a big thumbs up from a couple seniors…”

“KNZ saved us! Our heat was not working at the office with temperatures at record lows, I called KNZ and they cld back asap to let me know they’d be out in an hour. They made it here in 45minutes. Our guy was personable, fast and got us going within the hour. My coat is now off inside and we can see patients again. Thanks KNZ!”

“A neighbor recommended I call them, and I’m glad she did.
I called the office and the lady was very patient and knowledgeable..she asked questions about my problem and gave me ideas on what to check..it turned out my thermostat was messed up..The man came, checked it out and replaced it..then he also checked out my furnace and air..he was so nice.. being a lady in her 70’s..the service guy made me feel very comfortable..I would definitely recommend KNZ.”

“Excellent customer service! They were called by my landlord to fix a furnace issue. The lady in the office who set up the repair appointment was so kind and helpful. The guy who came for the appointment was on time and very professional. He was mindful of COVID and protecting us as well as himself which I appreciated. He did a thorough job and made sure everything was working before leaving. He also explained to me everything that he did. I highly recommend.”

“Came to house looked over the old furnace installation made all necessary measurements and prepared a quote and scheduled installation before he left. Called the day before the installation to confirm date and time with us. They arrived the next morning at 9:00. Brought 4 people. Removed the old installation inside and out. Removed old equipment from basement and back yard. Installed New Furnace and AC unit. Installed Air conditioning lines, Piped Gas and Electric to the new unit and tested both the Air Conditioning and Heating. Cleaned up all work areas completed paperwork, and left by 3:00pm. Very Satisfied with their work. All work is neat and professional looking.”

“We did our own research and found the best company in the area! It was a pleasure doing business with you, Keith; we thank you and your staff for the great job. We will definitely recommend your company in the future.”

Gerrit D.

“Thanks so much for the “white vents” and for your info on the “dehumidifier” and have outside vents open for the crawl space. Warmest Regards.”

Jim C.

“As a retired Thermal-Mechanical engineer. I can attest to the fact that KNZ is a complete and professional HVAC systems contractor. KNZ was competitive (second low of five bidders), the only contractor that figured out how to reasonably install the top efficiency furnace, and removed an uncomfortable draft and temperature differential problem we’ve had in our home for years.”

Tom and Janell D.

“KNZ You did a great job of removing our “old” furnace and replacing it with new. The men were prompt, courteous and did a good job of cleaning up. We are enjoying our new furnace and central air. We would use your services again, but we hope not for a long time. We would highly recommend your services.”

Pam D.

“Just wanted to Thank-you for getting our job done as fast as you did. Thank you.”

Rev. Lawrence E. Sinick

“Dear Mr. Miller
We at the Apostolics of Lowell would like to extend our gratitude for the wonderful new furnace and air conditioner. The price was very reasonable and your installation crew was very diligent. They made sure everything was done right.
Our church is not very large, and in this economy, contributions are not enough to meet all of our needs. This fact makes us apprecaiate KNZ for giving us a very reasonable price. I can surely recommend KNZ to others who need kheating or cooling service or sales.
May God bless you for your kindness.
In Jesus’ Name,”

Kyle

“KNZ installed a server room air conditioner for us quickly and professionally. Much appreciated Keith, hopefully I don’t have to call you any time soon, but if I do I know you’ll have me taken care of.
Thanks”

“KNZ is the contractor used by our builder. Kieth came in and talked to us about how we going to use the rooms. He then went through the plans and with our input, put together a comprehensive plan to make best use of the heating and cooling system. The craftsmanship and professionalism of his employees is the best I have seen in years. The follow up has been excellent this fall kieth stopped by to check on everything to to make sure everything was still to our liking.”
