Our air conditioner died right before the hottest day of the year (Go Figure!). We called Zenner & Ritter to come and take a look. Our system was old so they helped us pick a new Air Conditioner, Furnace, and Hot Water Heater. They only suggested quality brands that were easy to research. Our estimator and subsequent Technicians/Installers also made a point of listening to my concerns about uneven comfort in our house depending on the season. They took a look at my duct work, made the necessary modifications, and took the time to instruct me about how to set the dampers depending on the season. Awesome all together. 5-Stars!

Wonderful experience! I just purchased my home and the new furnace had the Zenner and Ritter sticker on it…and since I’m unfamiliar with the area, I decided to go to them to add central air. The service was very prompt and courteous. The salesman came to my home on time and explained to me the various options and price points, as well as the importance of a “matched system” (same brand furnace and central air component) the installation went smooth and the guys were great. Explained the functionality and cleaned everything up. They even installed a new covered GFCI outlet to replace the existing one, even though it is not part of the cooling system. Next year I will be getting an air cleaner and humidifier. I highly recommend them!

Great experience very helpful employees. Each employee provided expert knowledge about every product they sell. They provide that customer experience that makes us want to use Zenner & Ritter for all of our heating and cooling service and tune ups.

Thanks again to Rob, Mike and team for the A/C really saved us in this heat wave!

The Zenner & Ritter Team was very professional. They even came out in a terrential rain storm. They work in teams for Gas, Electric and there is even a foreman on site. They completed the generator install in 8 hours. I would pick them again and they do other stuff as well. They are local and give them a call! We are very pleased. The Kings

We have been using the services of Zenner & Ritter since a couple of years now; we are so satisfied with their excellent work. Always these gentlemen provide an outstanding job, everyone is very professional, knowledgeable, neat, friendly, polite, punctual.
Also, Maria the receptionist it’s fantastic! I think without her intervention, we won’t be able to get these incredible guys to help us.
Well done Brian, keep up the good work!

Kurt and his partner Brandon arrived promptly as scheduled and installed a replacement airconditioner for me. At the end of installation Kurt demonstrated how to use the system and provided some ideas for maxmizing the efficiency of the unit. Would recommend Kurt and Brandon.

Andrew replaced our Air Conditioner control board and continued to troubleshoot the system until it was working properly. Not something he has worked on often but, he was able to setup the board and get it working. He was very polite and professional.

Matthew Dux was courteous, efficient and explanatory.
Also, very knowledgeable when serving the air- conditioner and furnace
and did an excellent job.
His expertise was very much appreciated.

Thank you UH

The serviceman from Zenner & Ritter provided excellent service when called to repair my mother’s furnace. He explained the problem and fixed it and made us aware of possible problems in the future. I called them because they had cleaned my furnace and I was impressed with this company.

Had maintenance performed on our whole house generator, air conditioner and furnace. Very professional. Our technician Greg was very personable and thorough.

The technition arrived on time and when scheduled. He was thorough, neat, and he explained exactly what he did. H e was very polite and seemed very skilled.

Andrew was very courteous and helpful in giving information on how to keep up our furnace and air conditioner. Very professional.

Excellent service, customer friendly, knowledgeable & informative technician. Friendly & courteous scheduling person. I rate Zenner & Ritter, Inc., an exemplary company and would confidently refer them to my family and friends!

Outstanding service. Keith came within two hours of my call. He diagnosed the problem — after another professional HVAC man had been there the day before and the furnace still did not work. New furnace needed installed within two days. Outstanding. Keith was professional, thorough and kind. I 5star this company.

Our repair person was very professional and took the time to let me know what he was doing. He also made a suggestion as to how we may keep our A/C drains clean and save some maintenance cost.

Great Technician- 20 yrs.with Z & R, great communication prior to arrival and after, through evaluation and cleaning of unit and explanation of how to optimize life of unit and considerations in future when unit finally fails as all equipment will. It can’t get any better.

I had new central air installed in my home about 9 yrs ago and a new furnace 5 yrs ago by Zenner and Ritter and I’ve used them exclusively for routine maintenance. This is a very professional company. They go over and above the standard. Last year I had a problem with my air conditioning and Greg found the problem in about 10 minutes. He came again this year for the routine maintenance and he remembered us. Greg is professional, knowledgeable and personable. He makes sure you understand what he is doing and why. I highly recommend Zenner and Ritter and Greg as well.

My new central air needed to fit on top of an older furnace and they did a great job installing. I did need a minor adjustment made and the very next morning at 9:00 am, the tech was here to ensure I was totally satisfied.

On time Did a good and fast job. Good clean up

Tim, the service tech was extremely efficient and had no problem fixing my unit. I would definitely refer Zenner and Ritter to all friends and family.

Greg was very knowledgeable and took care of my problem immediately. He was friendly and caring!

Eric from Zenner & Ritter just left completing a replacement install of a Rheem high performance gas water heater. He was very professional and efficient. Completed all the work in less than a hour. Took time to explain to me how the new unit works, including simple maintenance tasks that I could easily do that will ensure good performance and longevity from the water heater. Eric gets a A+ rating

Andrew was a Knowledgeable and friendly tech

Andrew was very polite and professional.

Today Dave Zawislak of Zenner & Ritter resolved a significant problem with the plumbing in an upstairs bathroom at my home. Dave’s work was superior, and never again will I use a plumber other than Dave. Hopefully after reading this neither will you.

Earlier this year my wife and I contracted to have an upstairs bathroom remodeled. That job was performed by a bathroom contractor, and at the end of that project we experienced what the contractor thought was a leak in the drain of the bathtub. The leak damaged part of the ceiling beneath that drain, which is in our laundry room, and the contractor removed a large part of that ceiling to fix what he thought was that leaky drain.

The ceiling remained “open” for about a week as we waited for the contractor to return to finish the job. I eventually resorted to finishing the ceiling drywall work myself, and in the meantime the hot water tank in our basement failed. As the adage goes, when it rains it pours, and at that point my wife and I decided to contact a professional to install a new hot water tank.

Our search for a quality plumber led us to Zenner & Ritter, and they sent master plumber Dave Zawislak to our house to perform the job of installing the hot water tank. Dave was punctual, clean and highly professional, and he efficiently and effectively installed our new hot water tank.

During that job my wife prevailed upon Dave to look at what was then our open laundry room ceiling and the plumbing therein. Dave was kind enough to do so, and he warned us that the contractor’s job looked slipshod. Based on what he saw, Dave though that there might be other problems with the contractor’s work.

Unfortunately, Dave was right. After patching the laundry room ceiling, I painted the laundry room. In the course of painting that room I removed the cover of the light switch therein. Fortunately, my wife happened to be showering in the newly-remodeled bathroom at that time and, after removing the light switch cover, I noticed water dripping into the light switch gang box. That dripping caused me to inspect my basement, and there I saw that the water had continued past the light switch through the floor and had puddled in the basement.

At this point I called Zenner & Ritter and asked that Dave return to my house to solve the leak problem. Dave did so today, and as noted his work was excellent. Dave quickly determined that the dripping at issue flowed not from the drain of the bathtub, but from the showerhead of that unit. Dave fixed that leak, and he explained that the showerhead was installed improperly and not tested by the contractor before the wall of our newly-remodeled bathroom was closed.

More importantly, after finding the leak in our shower, Dave was careful to test the water lines between the showerhead and the drain, and that prudence paid off. Through that testing Dave identified two additional leaks and quickly and cleanly solved those problems. In doing so, Dave expertly communicated the nature of the problem and provided a detailed explanation of the proposed fix and the additional expenditure of time necessary to close each leak before efficiently solving each problem. Dave was also kind enough to provide advice beyond the scope of his plumbing work with respect to our remediation of the damage caused by the leaks.

To the extent you seek a plumber that is professional, timely, courteous, efficient, well-spoken and, most importantly, a master at his craft, look no further than Zenner & Ritter’s Dave Zawislak. I could not be more appreciative of or impressed by his economical resolution of what was a very vexing problem in my household. After this experience, I will never contact a plumber other than Dave. I hope he is the first and only plumber on your list as well.

Their technician did not call the owner of the property despite giving them specific instructions to contact before he came in. I called the owner and asked him if he could let me know what work was done. Mr. Brian Ritter (Owner) came in personally today and explained to me what work was done on the unit. I gave them 5 stars as Mr Ritter had the courtesy to come in to explain and has good business ethics.

Gary came out and took care of everything! Very efficient, knowledgeable, courteous, and respectful. Awesome guy, great service and very reasonable. I will definitely be calling them in the future – and requesting Gary – when I need them.

Called for furnace repair on Sunday. They were willing to send someone out right away. Seemed like a well run family business by the way the staff answered the phone and communicated. A part was ordered and installed in just a few days. Very friendly, respectful (we have young children who were sleeping that evening), and fair. Thanks for the great furnace service in my Amherst, NY home!

Fast service excellent price works beautifully !!!

Very good experience

Today, a service tech named Gary came to my residence to repair my a/c. He was polite, did his job professionally and answered all my questions. Zenner & Ritter is lucky to have this tech/

Keith came out and installed a new furnace. Very friendly, professional, polite. I am very happy with the service, and so far the furnace is working quite well. They were also very respectful of the house and took their shoes off before coming into the home, unprompted from me.

My furnace broke down in the middle of winter- I asked a few friends for referrals and Zenner & Ritter was mentioned by more than one friend. So I called them and they came out within a couple hours. The tech was extremely nice and friendly. After his recommendation to replace the furnace, I did so with Zenner & Ritter. (BTW he was not pushy, he basically said that I need to replace it but I can go with anyone I choose for the new furnace)! He recommended surprisingly the most cost effective one, which I trusted and went with. (Many companies would try to get you to get the most expensive product and be pushy about it). This tech was not, which I appreciated. After I chose what I wanted, they were out the next morning installing it. So far, works well. All the techs that came out were really nice. Spoke to Nathan from Z&R on the phone, very nice and professional.

Would definitely recommend. After speaking with Nathan, I am confident that if any problems arise, he’d make sure his customer is happy. Thank you Nathan and to the techs who helped me out at Z&R!

This is to RAVE about the service that your company provided in response to my recent request to diagnose the furnace problem in my home From the first call that I placed – to every phone call returned thereafter including Gene the Service Manager office assistants – to Steve who diagnosed the problem – and finally to Keith who installed the new furnace – EVERYTHING was done with great respect, professionalism, friendliness, and quality. I received calls back as promised Now that’s a rarity in today’s world of contractors Prices did not change. Another rarity. Steve Keith were on time – another rarity. And, Keith the installer went the extra mile explaining everything to me, cleaning up, and replacing filters He also called the next day in follow up to a question I had. He obviously is a happy employee, and this company is to be complimented on the quality people they have working for them. I would recommend their services anytime to anyone…keep up the good work!

I am a single mom and I have to be able to trust the companies I use to do repairs for me. This is one that I DO! a few years ago I had them install central air in my home. The istallers did a wonderful job. They even checked out the furnace and found the heat exchanger was cracked. This crack could have let CO into my home if I had used the furnace. I had justed purchased the house and had a home inspection done before I purchased. The inspector missed the crack ! I had Zenner & Ritter install a Heil furnace that work great! These guys are the BEST!

I’m very pleased with Z&R from the initial contact up to now with everything installed and running. We didn’t even know we qualified for the NYSERDA deal where they basically pay for half of all energy star systems you get installed. Earl (the point man) explained everything very clearly, was helpful with questions and was a great guide through the NY State rebate maze. As for installation; they said, “two guys, two days” and that’s pretty much it, though it was, in reality, two guys and one and a half days. These guys /go to work/! They introduced themselves, and went, immediately, into the cellar and started the job. These are true professionals, they adapted the furnace, A/C, and tankless water heater on the spot to the buildings shape and size and did so in a way that was efficient, clean and uncluttered. If your rushing to find a quality outfit with knowledge that will hold your hand from start to finish…go with Z&R.

I just had a heating / cooling system installed. Bob Fraser, my salesman was very professional and answered all my questions. He was particularly responsive to my needs and what I wanted. Others quoted what they wanted! He made suggestions not demands and was encouraging me to ask questions during the selling process. He did not try to over sell me. He even offered to evaluate the other quotes if I wanted. Jeremy and his helper were very professional in the installation process. They allowed me to look over their shoulder during the whole process. That showed confidence in their work and knowledge. His suggestion to relocate the A/C to the corner of the yard as opposed to my original location was a good one. A potential electrical problem was quickly assessed, and resolved without incident. I would highly recommend Zenner & Ritter for all your heating and cooling needs.

Have had nothing but good experiences with Z&R from the original purchase of the furnace/boiler to annual maintenance and repairs. They have been quick to respond in bad weather emergency service calls and prices are certainly competitive. Would not hesitate and have not hesitated to recommend them to friends and family.

There service was great. They [resolved] my problem quickly and at a fair price.
