We love receiving feedback from our customers. Check out what some of them are saying. 


As a loyal customer of Kermit B Schulz & Sons since 2011 I cannot express how delighted I am with their services. Recently my HVAC system was serviced by Karlie, a new addition to the KBS team. I was thrilled to see a young woman in this position, and she exceeded my expectations. Karlie was an absolute delight and performed her job perfectly. She even went the extra mile by bringing my porch cushions up from the basement. 

Every KBS staff person I’ve met has been exceptional. They consistently go out of their way to be helpful, kind and accommodating. Clearly KBS holds customer service as a top priority. I highly recommend KBS to anyone in need of HVAC services.

 I would highly recommend KBS! They were responsive when we called because our HVAC was blowing warm air. The technician explained our options, and their staff person came out to speak to us and quoted a price. About a week later he called to set up a date to replace our HVAC. The technicians arrived on time, kept everything clean, did a great job, were knowledgeable, polite, and went above and beyond. KBS will be our heating and cooling company going forward. Call them!!!

 We are very pleased with the 2 mini-split / heat pumps we purchased from KB Schulz. The entire team was very professional & knowledgeable, and made sure everything was working properly, & we were satisfied with the product & the installation. We high recommend this co.

 I highly recommend Kermit B Schulz & Sons for A/C installation. In May 2022, KBS installed a new A/C unit, replacing an old central air system. Initially, I obtained six quotes to replace the system. Four of the six businesses tried to upsell me. KBS provided a thorough and honest evaluation. Their quote was detailed, payment options straightforward and pricing affordable. KBS showed up on time and completed the job as specified. They even left the site job neater than it was originally. I could hear the men talking as they worked in the attic, and the pride in their work was pleasant to hear. The new A/C works great; quieter and more efficient than the old unit. I would hire KBS again and plan to call them for any future maintenance.

 Kermit Schulz sent two highly experienced individuals to our apartment to replace the air handler and AC condenser. It was a scorching day and the guys needed to work in the attic replacing the air handler unit. These guys worked through the heat and got the job done. Now the AC is running at peak efficiency, and it's so much quieter. Thank you.

 I have been very pleased working with the Schulz company over the past 20 years at my last home and my current one.

 We have been doing business with KBS for over 13 years. We continue to do so because we are dealing with a group that not only is knowledgeable but pleasant, courteous and responsive. Don't think there is more to say. Thanks KBS for your service.

 My technician went above and beyond when he discovered an issue in my basement unrelated to servicing my furnace.

— Mary Shea

 My experience with Kermit B Schulz was excellent. The were prompt, well informed and did an outstanding job with communication and installation of my furnace and AC unit.

— Linda Drew

 The service call was on a central air unit we had already decided to replace. The tech came the same day and replaced a broken part, which helped keep us cool until the new unit was installed. We have a service contract so the visit was free. The new installation was done seamlessly. The men were knowledgeable. skilled, and courteous. They came on time, completed the job that day, and totally cleaned up. We are and have been totally satisfied with our service over the years. Betty is great to work with for scheduling. I highly recommend the company.

 Schulz Co. did a fantastic job! The team arrived masked, finished installing the split for our downstairs ac within the day, answered all of our questions and left the areas they worked in spotless. Have already recommended the company to neighbors. Better estimate for the work than other companies and great job!

 The KBS crew recently replaced my gas furnace and AC system. I like those guys! They were on time, courteous, efficient, quick and clean. The system works great and I couldn't be happier. What more can I say? I highly recommend The Schulz Company.

— Tom Nolan

 Kermit Schulz and Sons installed both our current heating and air-conditioning systems. They had installed and maintained the previous heating system--which served for more than 40 years. We have been very happy with the quality of the work and equipment, and the friendly, professional service they provide.

— Susan Parker

 Brian, Thanks to you and your team, the system is working great! I appreciate all the hard work and coordination to make this happen!

— Jonathan Pepin

 Brian, Thanks for having the HVAC installation up and running today. It is working splendidly, and I am grateful for the job well done.

— Best Wishes, Lois Swirnoff

 I am very pleased with Kermit B Schulz. They installed a new furnace, quickly, two years ago, in very cold weather. Lots of attention to detail! Their staff is very pleasant and responsive. They have regularly scheduled annual service, and they take the time to inspect and change filters, etc. A little expensive, but I think they are well worth it. I definitely give them a thumbs up.

Cheryl Jeffrey

 I couldn't be happier with the service I have received from your company. If the need should arise, I will definitely use you in the future, and will not hesitate to recommend you to friends and neighbors.

Joanne Buerger

 Thanks so much. I am very happy with the service and would be happy to recommend your company to anyone.

— Mary Crowley

 Thank you for the great service. We are enjoying our new A/C and hope to be doing so for years to come.

John & Janey Byrne

 I thought you would like to know that I was very pleased with the service provided by your employee, Brian. He is very professional, and took the time to explain why my AC wasn't working. He understands what customer service is all about. He is a credit to your company.

Jean Nichols

 I am enjoying my new air conditioning system on these hot and humid days. I am pleased with your excellent work, and I appreciated the courtesy and professionalism of the men who did the work with so little inconvenience for me.

 The Grignaffini Construction Company of Wellesley has used the Schulz HVAC Company since 1957. It has been a very pleasant experience.

— C. Joseph Grignaffini, President

 Just to let you know that I think (the website) it's wonderful. You started servicing me when I lived in Wellesley. You installed our heating system, I guess back in the late 70's. Thanks for being there for me. And a great big hug for Betty.

Sandy Allen

 Thank you so much to your prompt attention to my emergency. The heat was becoming unbearable! Ken + Joe were efficient and a pleasure to explain my problem. I'm keeping your address in my files and look forward to recommending your company to friends.

— Diane Jones

 To Whom It May Concern - Please accept this to provide my evaluation of Kermit Schulz Co. I have experienced the company to be superior in their installing my ductless AC system! I give permission to post this as you wish. They were professional, courteous + extremely helpful in all ways. Estimate, service, installation - I highly recommend this company to anyone!
