THANK YOU for being able to make it out to repair my mother’s air conditioning today.

I can’t tell you how relieved my brother and I are now that the problem has been identified and fixed.

I appreciate your priority scheduling very much.

Thank you for your speedy and comprehensive service. I very much appreciate the human touch, and thoughtfulness of your technicians and office staff.


Katham Industries responded quickly to my request to problem-solve air-conditioning breakdown. Technicians were professional and knowledgeable!

Very happy with Katham’s work. Recommended.


Have been a very satisfied customer of Katham Industries for close to 30 years. They installed our A/C and heating system during a home renovation, maintained the system, and just installed a new unit for us. Gave us options, fixed a ventilation problem, timely installation, and removed old unit. All done professionally and with courtesy. You are making a wise decision when using Katham Industries to maintain your unit. Plus they clean vents including dryer vents!

The Technician (Lane) was very professional and knowledge, and managed to provide different options as to how our problem could be solved. Super quick turnaround and timeliness were also a trademark. I would certainly go back to do business with Katham.


Katham installed a new A/C system for our main floor residence. A good quote and excellent installation. Showed up on time and did the job as quoted. System working perfectly. Would highly recommend this company for your A/C needs.


Katham provided excellent quality service for us as our AC broke down suddenly and we needed a partial repair and replacement of our system. George made sure to oversee the entire job. All members of his staff, from those in the office, repair team and installers–William and Miguel were on time, careful, polite and did a wonderful job restoring our system to normal. Thanks!!!


We hired Katham Industries, Inc. to replace our 25 years plus Carrier Central Air Conditioning system (condenser/fan and coil unit). Before we hired them, we got quotes from several HVAC contractors. Katham’s prices were competitive and reasonable, and they exercised esteemed professionalism from the start and had a simply no-pressure approach. George, the company owner, came to our home, assessed our situation, and explained our options. He did not once give us the typical sales pitch and pressures that we had heard previously from other contractors. We greatly appreciated his approach. He also gave us sage advice on expanding our current system to include an unserved space in our home.

After we decided to go with Katham, we had a few follow-up questions about the Quietwave and Air purification, those questions were promptly answered, and to our pleasant surprise, George was able to fit us in his schedule right away (versus a 3-4 week wait as offered by the other contractors). On the date of replacement/installation, PJ, Daniel, Miguel, and James arrived at our home on time (8:30 am) and knew what to do. They, like George before was very respectful to our home regarding taking COVID precautions.

We are glad that the professionalism at the top filtered down to the first class and friendly installers. I worked from home the day the installation was done, and I was not disturbed once. They had a team working inside on the coil in the attic and another team working on the condenser fan on the outside. They were finished by the time the temperature hit 93 degrees. They cleaned up, left no mess, showed us how to change the filter, and also programmed our thermostat. In the end, we were grateful for their service and hard work and will be sure to recommend them to friends needing a new system. Thank you, George, PJ, Daniel, Miguel, and James.


Excellent experience working with George and team for an install this year. Tricky install – retrofit into a tight space. Required creativity on the part of the team. George was accessible, prompt, professional, creative et al – great customer service. All around, really glad we chose to go with Katham, and would readily recommend with 5 star rating.

Recently installed new HVAC in my 1930’s house. Katham was great to work with from beginning to end. Very responsive to my concerns, worked neatly, courteous owner and staff. My house feels so comfortable now …. wish I could have done this sooner!

Melissa L.

Wonderful people always respond quickly…. very efficient and always courteous. Love Athina at the office.

Judy k.

Katham replaced my AC within 72 hours of my request; the entire system needed replacement. They came out to evaluate it the day I called to inform them of the problem; they didn’t give me a 4 hour window like most companies. they gave an exact time and were very prompt. They were honest and fair with the pricing. Very efficient and professional. Highly recommend them!

Sabena S.

Katham Industries installed an entire new HVAC system for us two weeks ago. George and his team of technicians were a pleasure to work with. Professional, efficient, responsive, neat and trustworthy. Very happy with the new system. We highly recommend Katham.

Hanna F.

Excellent service, responsive, and professional team! Starting from service call to implementation. Looking forward to many years of continued service!

Julio P.

George and his team are fast, reliable and professional. They have helped me with problems big and small. I would recommend them highly.

Aaron L.

Katham Industries completely renovated our 1985 central AC with much needed new ducts, output and intake vents and dual zone thermostat. Couldn’t be happier with the results and the painless process. Absolute professionalism from A to Z.

Amelie F.

Finding Katham Industries was a true blessing, after having had many unpleasant experiences with multiple HVAC contractors. George is responsive, knowledgeable, honest and polite. He took the time to review my problems, discuss them with me, review options and offered detailed and competitive quotes. His team is always on time, prepared, clean and respectful. I wish every contractor was this efficient and pleasant to work with. Thank you!

Francesco T.

Needed a new boiler and was recommended to Katham by a friend. They responded quickly, came in with a fair price, showed up when they said they would, did the job neatly and professionally and were pleasant to deal with. No surprises, no hiccups. Highly recommend George and his team.

Katham is a top notch HVAC company that did an excellent job with an installation for me. They went above and beyond and are extremely respectful and responsive. I will definitely be using their services going forward.

Jonathan F.

I recently switched my HVAC maintenance contract to Katham Industries, and am very pleased to have done so. George and his crew understand the technical issues at hand and are eager to come up with workable solutions. For example in my case, I had waited several months for a contractor to switch out my humidifier which was still under warranty. Once I spoke to George about the situation, I was confident that it would be taken care of, and it was! He not only is knowledgable, but possesses unique people skills that most other HVAC companies seem to lack. Athena and his crew are considerate, competent and accommodating. Overall, we have been extremely happy with Katham Industries.

Wayne B.

We needed to replace our AC after many years!! We called Katham and George came the next day, two days later we had our AC just in time for a heat wave, we couldn’t be happier!! They are a great team of young men, very polite! professional! and knowledgeable! They did a wonderful job!! Thank you!! to the whole team and George!

Ingrid O.

Our entire air conditioning system broke down suddenly and had to be replaced. Katham did a great job. High quality equipment, excellent technicians, responsive and timely. They came into the house and left without creating a mess. The technicians who did the installation were wonderful young men, polite, clean, always on time and attentive. George Katrandjian is a pleasure to deal with, and his assistant Athina is wonderful, too.

Martin T.

I’m very happy with the installation of my central air conditioner system this year. George, the owner, came by to inspect and gave me a very competitive bid for the job. His workers were very professional during the installation, and completing the job quickly.

Joe V.

Great job and quick response.

Michael B.

Katham Industries has been servicing my HVAC in my home for years and is a family owned business. Their responsiveness, reliability and experience is first rate. Plus their prices are fair and competitive. Wonderful company and people.

Donald B.

We had AC servicing. They were very professional and were extremely careful to observe all the social distancing recommendations. They responded very quickly. I would highly recommend them.

Paula J.

I was referred to Katham Industries by my neighbor when my pilot light was out and I had no heat on March 7th. I received a call back on a Sunday from the owner George and informed him of my issue. He then sent a Technician to my residence on Monday and they were on time. They informed me that I needed a new boiler. They took care of ordering the new unit for me and they were able to replace it in one day while I was able to work from home with no interruption. I found that his team is very professional and they clean everything up as planned.

P.S. Thanks George for calling just to see if everything was working well.

Robert M.

Katham Industries has installed our furnace, central air (in a 70+ year old house with no ductwork), and while house generator. We have consistently been more than satisfied with the quality of their work, quick response, and competitive pricing. We highly recommend this company.

Susan G.

The entire Katham crew is totally professional: dependable, friendly, and above all, efficient. It’s comforting to know that there’s a service we can rely on in summer and winter alike.

George S.

We have used Katham Industries for several years to service the commercial heating and air conditioning units in our facility. George and his staff are a pleasure to work with ~ they are always friendly, professional, quick to respond, reliable, and knowledgeable. We highly recommend their services.

Maureen M.

This is an excellent company to do business with. The owner, George, is honest, knowledgeable and fair. The service technicians show up on time, put booties over their shoes before entering the house, and are polite, respectful and extremely good at what they do. Athina, the office manager is efficient, pleasant, and totally on the balls. There is nothing not like. I recommend them highly!!!

Giselle H.

On time as promised. The technician made his inspection and gave his opinion including expected cost. Although this was inspection call only, if future work is needed, Katham is definitely the one I’d call.


They are always there when you call them right away and always try their best to salvage your old unit as much as they can! We couldn’t ask for better service. and we highly recommend them!


They are honest, timely, and respectful. After being told by A.J. Perri – a scam AC repair company – that I needed a completely new system, AC coil, condenser etc. and that it was going to cost me $10,000, Katham came out was honest and had my system up and running in less than two hours to the tune of $600. Will only use Katham from now on.

Erinn M.

Katham was just perfect for us. While they are always supper efficient in the annual maintenance they were amazing in installing a new system for us. They were timely, clean, and proficient most importantly the crew was so very nice.

Steven R.

I love this company always there for me for I’ve 25 years I can’t thank them enough. They are honest, fair, punctual, have work ethic and pride in their work. They behind everything they do and are there immediately when I have an emergency.

Amy P.

Professional, personable, and punctual! The entire team at Katham Industries really show a high level of care and quality service. They answered the million questions I had and really made me feel like I was their only client. It is nice to know that knowledgeable, trustworthy and reliable HVAC companies with fair pricing do exist!

Zain C.

Excellent experiences with Katham Industries for both installation and repair. We have found them reliable and professional . Their prices are fair, the owner George is knowledgeable and honest and Athina at the front is super efficient and friendly. Highly recommended!

Maral H.

We highly recommend Katham Industries for your HVAC needs. The HVAC installers are skilled professionals and the installation was thought out. They maneuvered around the available attic, ceiling, wall, and floor spaces to provide the appropriate air register quantities needed for the home. This is not necessarily easy as we had an open concept layout. The ceiling registers were proportionally placed and in a good visual line with the ceiling lights. All workers were exceptionally good hearted professionals saying ma’am and sir. At the end of the job they took away all of the waste packaging materials. We were really pleased and used them to replace our rental property HVAC unit as well. Thanks for jobs well done!

Glenn P.

Always available. Extremely thoughtful management and always here on time. I recommend them to anyone who likes service that is excellent.

Alice S.

I’ve been a client of Katham Industries for 10+ years, they always respond in a timely manner & have always provided excellent service starting from the person who answers my calls to the end of each job. The technicians are very professional & knowledgeable. George, the owner, is always ready to step in when needed, providing valuable expertise.


Time and time again I have called upon Katham Industries to take care of all my heating and air conditioning needs. From cleaning to repairs to custom orders, they were professional, timely and courteous. I can’t say enough.

Ani M. W.

I didn’t know service at THIS quality was even available! George made me feel very taken care of, and his team did his work quickly, efficiently, and with great care. I felt the price was very fair.

Immanuel S

I reached out to George at Katham Industries at the recommendation of my local plumber. My old furnace had finally died and I wasn’t pleased with PSE&G’s response to the emergency. George came for an estimate immediately after I called and he and Athina were extremely helpful and professional throughout the process. The team that came to do the job was polite and efficient. George took the time to introduce me to everyone and supervised the job carefully. This was a big, messy job yet they were done in one day and they left my basement floor cleaner than when they started! I highly recommend Katham Industries.

Susan G

George/Athina – PJ and his co-worker were on time, most pleasant, knowledgeable and presented themselves in a friendly and professional way. This is especially nice considering the younger side of their age bracket. I thought you should know and if you need this to go on a website it would be my pleasure.

Lawrence O

The choice is simple – You should use them. I purchased a house that was maintained by Katham. It was an older home, but you wouldn’t know it from looking at the mechanical room. The boilers were 10 years old and looked like they were new. The inspector told me that he knew of Katham and that they were awesome. Naturally I kept them and I’ve been thrilled. Scheduling – You call and you get a quick appointment. Customer Service – You have questions, they get answered quickly (same day). Ownership – Really cares, and that gets passed through the organization. Value – This is the real metric. If you only look at price, these guys may not be the cheap answer (they’re certainly not the most expensive either). Having said that, these are expensive systems that can break. So you need to look at the cost of saving a dime upfront. You have a choice you can be proactive and make these systems last for a long time, or you can go with the cheap guys and get hit with surprise and premature replacement bills. Again the choice is simple – you should use them.

Daniel R

Professional, affordable and reliable. My restaurants AC had stopped working and the techs had it up and running in under an hour. I can always trust the honest work from Katham Industries.

Peter K

Professional & generally very responsive – we have used Katham for the past 5 years for maintenance, repairs and minor jobs when required.

Pinaki R

The best people to deal with. Personal and honest approach and professional work.

– Dusan R

Wonderful company. Pleasure to deal with.

– Dennis S

My husband was the one who interacted with this group. He wanted me to tell you all that Katham did a great job from estimate to installation. What is a very big expense and can be very confusing, Katham walked my husband through this process and helped us make a decision that we could feel confident with in the end. Katham was recommended to us by the a family in Englewood Cliffs and we will be sure to recommend them to anyone who needs a new central cooling system.

– Lisa D-G

Katham is terrific! I have used them for repairs and maintenance in the past but this year I needed a new central a/c. They were prompt, neat, and George set me up within 24 hours for the new installation right before the heat wave began.

– John H

Highly professional heat/a.c. company. Always on time techs, very courteous, and also a great value. George the owner comes out initially to meet/greet and ensure new customer satisfaction. Strongly recommend!

– Anthony A

George and his staff are very responsive, educated, and honest. Highly recommended.

– Robert K

We had previously used a few other local companies for some issues both major and minor, but were never thrilled with the service (can you say huge leak!) so when our basement system kicked the bucket, we figured we would give Katham a try. They sent someone right away (in a snowstorm) to diagnose and came back in the morning to replace the piece. Fast forward a few months and we called them for another issue in our upstairs unit. Again they came right away to diagnose and fix the issue. We’ve also had them install a new exhaust after a kitchen renovation. The owner goes above and beyond for his company and the Katham technicians are extremely clean, polite and very knowledgeable. After some nightmare situations, we feel we’re now in extremely capable, fair and trustworthy hands with Katham.

– Jaclyn H

I can’t speak highly enough of Katham Industries. I called them after our heat suddenly stopped working (outside temp around 12 degees at the time) on a Saturday afternoon. I spoke with the owner, George, who walked me through checking the furnace and exhaust vent for any blockages over the phone, and when that didn’t work he personally came out to our house. George diagnosed the problem as a bad igniter and swapped it out with a replacement he had with him. Within 1 hour of my initial call Katham had the heat working again, 5/5 great service!

– Michael H.

“Katham Industries recently cleaned our ducts and installed a new heating/AC system. They were very pleasant and professional from start to finish and reasonably priced when compared to other contractors. George (owner/president) as well as his mechanics were all friendly and willing to answer any questions and concerns. I would recommend Katham industries without any hesitation.”

– Joseph L.

“I have been using Katham Industries for almost ten years now. I have always been satisfied with their work. The technicians arrive on time (and call ahead, if they’re running late), cover their shoes when they enter my house, are always polite and respectful, and do whatever it is they have to do in a professional manner. The owner, George, is a lovely man, who knows his field and is honest in his assessments. I trust what he says and have never been disappointed. I would recommend this company without reservation.”

– Maria G.

“Finest HVAC personnel around. Our family has been using Katham for over 25 years. Many thanks!”

– H. Duke

“We were very fortunate to have found Katham Industries. There has never been a situation that they have not solved the problem, quickly and, professionally… with no need for a return visit. In this world we live in, to be able to count on exceptional service is more than comforting. George described options for a whole house AC system including the pros & cons, installed the appropriate air conditioning system for our 1886 home, The system has lived up to and probably exceeded even his expectations. Just the thought of Katham being around, is more than “comforting”.”

– Maureen M.

“Attentive, quick service with excellent and prompt follow through to resolve problems that previously others did not. We have done many projects with Katham from repairs and maintenance to generator installation and home addition and renovation. I would highly recommend this team having gone through using other companies in the past. Don’t hesitate to try them out.”

– Linda W.

“Prompt and excellent support service. Highly recommended!”

– Jose G.

“So friendly and professional. Great experience with George and the Katham team!”

– Liz R.

“Katham Industries just installed a 75 gallon hot water heater. The work was quick, excellent and fully explained to me. Several years ago they installed an entire air -cond sustem for my top two floors. They actually did the work while I was on vacation. I trusted them completely with my house keys. That work was neat and perfectly done.They left my home neat and orderly I will always use this company”

– Arthur W.

“It’s very hard to find a reliable service company. Over the past 20 years, I have tried dozens of vendors. Katham Industries is by far one of the best. I would highly recommend their services as they are professional, responsive and friendly. I have dealt with them for about 6 years (they have installed/repaired dampers, evaporators, a/c systems and exhaust fans for me) and I have never had any issue with any aspect of their services. If you want expert care and courteous attention for your Heating or A/C needs, I don’t know of any better company than Katham Industries!”

– George J.

“We have used Katham for several years and have always had a very positive experience. They are reliable, and trustworthy.”

– Ponciano S.

“Prompt, reliable, honest service. So glad I found them.”

– Glenn M.

“We were very satisfied with the installation of our air conditioning and air filter. The young men who arrived at our home were knowledgeable and competent as was Mr. George Katham, owner. The workers were friendly and respectful of our home taking care to keep it clean and not to break anything (They even wore booties on their feet to keep our floors clean). Before leaving, they gave us an explanation of the new equipment and a small demo of how things work. After cleaning and leaving, we never knew they were here.”

– Brenda B.

“George and all his workers were polite and professional. The addition of a central air unit estimate was pretty much what we were expecting and the work was done in a timely manner. When we did have an issue – a minor mixup- George was there to fix the problem asap. It’s nice to have a trustworthy company to depend on.”

– Ellen M.

“These folks were very professional. In the middle of a hot summer day, when the AC failed, they came the next morning and they stayed on the job for a number of hours until the problem was rectified. They answered a number of questions which I had. Very pleased. I’ll certainly keep their phone number.”

– Teresa F.

“Terrific company! Can’t say enough about Katham…professional, trustworthy, efficient, neat and very fair prices. I recommend this company and their services very highly!”

– Kathleen R. E.

I can’t say enough good things about Katham Industries. I called them for the first time because I was having a problem with my air conditioning system. I had been using another company for years and had never really been satisfied with the service. I spoke with Athina, the office manager, who was pleasant, efficient and knowledgeable, and set up an appointment with her for the next day. The technicians, who arrived on time to the minute (wow!), were well-groomed, personable and able to diagnose the problem immediately. They had the necessary part on the truck and my air conditioning system was up and running in two hours. The next day, Athina called to make sure that everything had gone well and that I was still “cool.” I was, and have been every since. Two weeks ago, I had the pleasure of meeting the owner, George, who came out to the house to give me an estimate on a generator. What a decent guy – and I had the estimate that afternoon – amazing.
