Van Drunen’s staff was very professional and installed my furnace quickly. Great family owned business and I will do business with them in the future.

Gail G.


I’ve worked with this company for more than twenty years. Excellent customer service.

John & Barbara Truby


We are very pleased with the services of Van Drunen Heating & Air Conditioning’s installation of our new furnace in September 2023. Wonderful communication and transparency from office staff in planning the purchase, as well as excellent service and professionalism during actual installation. We have been doing business with Van Drunen since 1989, and we have never been disappointed. Wonderful company and great people to work with. John & Barbara Truby

Lois M.


Great service and fair price for furnaces and install. Servicemen courteous and cleaned up after. Would recommend to others.

William C.


Great installation of a new furnace and AC. Called them to look at my mother’s furnace. Other companies told her that it needed to be replaced. After replacing a couple of wear parts in her furnace, the furnace is working great. They are honest and will work with to figure out what works for you. I have recommended them to other people. Great company to use.

Jesse M.


Excelente assistance during a hard time. Our heater broke down in the coldest day. They came right away. They assessed the problem and gave us our options. They installed a new heater the next day. We are most grateful. The workmen were great and so was the owner who came out and lent us portable heaters…

James P.


They really stand behind their products. My new boiler needed a replacement part and they came out and repaired it quickly and proficiently. Thank you very much!!
I would recommend VanDrunen Heating to everyone.



Great company to do business with. Very good service with fair & honest prices. I would highly recommend to anyone looking to replace their furnace and/or AC or if you just need service or a tune up.

Will C.


Complete service as always.

Carmella S.


Very professional, job well done each time they have serviced my home, always kind and respectful. Young lady that answers the phone is awesomely nice too.

Derek B.


New a/c and furnace installed. Very professional and timely! Thank you!

Rosanne B.


Air broke. A human answered the phone!!! Yay! Guys came out the same day, installed new ac. Professional Installation. All around great people to deal with. Highly recommend!

Breanna P.


Making major purchases are never easy. I felt very comfortable with the information I was given and knew my options from the start. My questions were thoroughly answered, and I felt at ease moving forward. Not only was Mike friendly, but he was patient and professional. I will continue to give my business to Van Drunen and refer them to friends and family.



My experiences with Van Drunen are always professional, timely, and successful. My air conditioning unit failed just days before the late August heat and Van Drunen saved the day!!

William A.


Eric from VanDrunen came to our home the same morning we called. He reviewed our broken HVAC system, and we decided to have a full replacement and upgrade of the system. VanDrunen’s team of technicians removed our entire HVAC system that same afternoon, and came back the following day to replace the system with a Lennox high efficiency system. The VanDrunen team did a great job installing the new system. We are extremely pleased with our new HVAC system and our experience with VanDrunen Heating and Air Conditioning.

Peggy D.


So very happy I had my new HVAC system replaced by Van Drunen. First major purchase as a widow, and they made the process seamless. And what I appreciate more is the after installation service. Their techs are knowledgeable, pleasant, and helpful. Love the help they provide when you call them. Absolutely a great company!

Donna P.


This could really be a long post, but I will keep it brief. This has been the greatest experience for me. I contacted Van Drunen last week about an issue with my central air unit. They came out the next day. A couple of days later, I experienced the same problem, and it was determined that I needed a new C/A unit. Two days later, the unit was installed to perfection. A couple of days after that, I began having issues again, and they returned immediately and resolved the issue. Now all is well. I appreciate their promptness in handling my problem, being that it was the week of 90+ degrees temperatures. All of the guys were great…. Eric (my first contact) was so easy to do business with. I am glad I took the advice of many other people and chose Van Drunen. They are my go-to for HVAC service from now on. Forever grateful to them.

Dave H.


Very good service.

Walter R.


When my brother-in-law had a problem with a broken air conditioner in 85% temps they jumped all over the issue and got it fixed!!

Dennis C.


Professional, quality, timely.

Mary S.


Van Drunen set me up with new AC in two days! Keith came to my house on Monday and new install completed by Wednesday 12pm. Efficient service with efficient AC!!! Very nice people to work with.

Stacie V.


This vendor was a terrific find. Eric was immediately responsive and on site the next day to price a new commercial unit. Pricing was very competitive and the install went smoothly with a happy tenant as a result. I would highly recommend them and will certainly use them again. Thank you Eric!

Nancy W.


A great local business came investigated the problem, told me a price which was reasonable and came the next day to fix my problem. Definitely would recommend VanDrunen Heating and Cooling

Craig H.


Eric, Dan & Mike came and resolved our issues [ New Furnace, 4 cutoff valve replaced] on time & Cleaned up afterwards.

Beth W.


Needed a custom fabricated piece made for an RV. Many places were not able to fabricate the piece I needed. Van Drunen was not only able fabricate the piece, but they did it in less than a week. Their pricing and customer service was superb. Will definitely be using and recommending Van Drunen in the future.

Heidi B.


Our furnace died on us on a saturday and we called the same day. They came out and the same day they installed our new furnace. In addition they were very helpful and informative in helping us with the financing. I would reccomend this company to anyone.

Matthew W.


Great service performed in a prompt and courteous manner, with a very knowledgeable staff!

Debbie G.


I needed a new furnace and air conditioner to be installed. I received 13 estimates, but the owner of Van Drunen came to my home with a picture I.D.
I was very impressed and liked what he stood for and trusted him more than any of the others who came by and quoted. They ended up installing 2 furnaces and a/c units. Since then, every time I’ve needed service, Van Drunen was who I would call. Their service techs have been very nice and always described what and why they were doing it.
I would highly recommend this company to anyone who needs service or new units installed.

Marilyn T.


The service I received today was professional and the timing was perfect. I have not replaced a heating unit in 10 years, so naturally the cost was a little shocking! But, I have used this company in the past at another location, and therefore, consider myself a repeat customer! I would and will recommend Van Drunen to others. Thank you for your excellent service.

Jeanne L.


Install fans in heating ducts to push warm air into two large room additions. Instant satisfaction of warmer rooms when installation was completed.

Melissa V.


Called Van Drunen today with a furnace issue and they came an hour later! Fixed the problem immediately and all is well. Extremely friendly and professional service. 10/10 would recommend!

James Manno


Ivan Kirk

I contacted Van Drunen long-distance on a Saturday morning because my tenant’s AC stopped working. They immediately contacted the tenant to schedule an appointment for Monday morning; the tech called me on Monday with a diagnosis and for repair authorization; and he completed everything in one visit! Fast, professional, polite and reasonably priced! Everything you expect when you call a repair

Richard Thomas

Called vandrunenheating for a second opinion after the first company said we had to replace the duck work and put in new cold returns .the owner of van drunken came out check every thing came out I didn’t need new duck work the two guys that came out to replace my air conditioning and furnace were supper nice very respectful and did a supper job I would recommend VAN DRUNKEN VERY HAPPY

Joshua S

We called Van Drunen for a second opinion on our Amana compressor unit after another company attempted repairs and suggested we replace the unit. Van Drunen sent Justin out within a few hours after my call. Justin quickly diagnosed a wiring issue, assured me he’d be able to complete the repairs, and then promptly fixed the unit. I was expecting the worst – having to replace the unit – and am now cooling off with my existing machine. I’ll be calling Van Drunen when it is time to replace!


From out first quote with Eric, to installation with Derek and Dan, this was such an easy process. They showed up when expected, worked efficiently, were friendly, courteous and thorough in their explanation of our new heating and air systems. They answered every question we had patiently and professionally, and left the areas they worked in impeccably clean when finished. We have known members of this company and/or family for years, but this was our first time using them. We are 100% satisfied, and their reputation speaks for itself. Thank you for incredible service!



Mark R.

We’ve been with Van Drunen company for almost 30 years. When our primary furnace died in the middle of the night last week, we called Van Drunen the next morning, had a quote by noon and professionally installed by Dan T. the next morning. This company cares about your family and treats you that way.

JStacy N.

I had a Lennox furnace and Carrier air conditioner when I purchased the house. When replacing my a/c unit, I wanted a Lennox. Of primary importance was staying with my contractor Van Drunen Heating. I was able to get both-a win-win situation.

Jeremy J.

I would like to say that the Van Drunen employees were extremely courteous and clean. They worked in a timely fashion and didn’t leave any mess behind. I would definitely recommend their services to anyone.

Rodolfo T.

I was referred to Van Drunen by my father in law. He had his heating and air conditioning installed by Van Drunen and was very satisfied with the professionalism and the honesty that was given. I value those qualities and hope that they continue to provide each customer the same honesty and workmanship that was given to my father in law and me. Companies like this are rare in this day and age.

Jessie G.

They are excellent, courteous, and timely. I would recommend them to anyone.

Geri G.

They were super nice and worked efficiently and quickly. No mess was left whatsoever. I would highly recommend them and will use them in the future as I require replacements.

Jim S.

Keith at Van Drunen came out to my house and gave me great information about my heating and cooling system, but one of the main reasons I chose them is he did not negotiate on the price and he gave me his best quote and it was not the lowest but the most honest. When they came out to install my system I was very pleased with the professionalism and quality of their tech. He took the time to answer all my questions.

Krista H.

I’ve been in my home for 12 years and Van Drunen had always provided annual service to my furnace and air conditioning. Love them!

Frank K.

I was COMPLETELY satisfied from the estimating to the installation! They were extremely efficient, including the clean up and hauling away, even sweeping the floor. As a Premier Dealer, Van Drunen is VERY qualified. As to the installed equipment ONE word describes it the best, FANTASTIC!! Thank You.

Tilman D.

Van Drunen is the best heating and air conditioning Company in the chicagoland area, with excellent courtesy, honesty, and professionalism.

Tony C.

The folks at Van Drunen Heating Co were patient in answering all of our questions. We were replacing a 27 year old Lennox pulse furnace and we wanted to make sure the replacement would give us the economy and longevity of that furnace. We also replaced our 26 year old air conditioner which bit the dust this summer. Over a period of a couple of weeks, we asked many questions and feel that the replacements recommended by Van Drunen should serve us well. My husband and I watched the installation team and it seemed top notch! The air conditioner works great and we anticipate the same from the furnace this winter. Thanks to Lennox for making such fine products!

Richard M.

I’m very satisfied with Van Drunen Heating. They installed the first unit 19 years ago and now they installed the new one. I trust them.

Edward M.

I have dealt with Van Drunen Heating Company in the past, and have recommended them to family and friends. I find Nick so honest and sincere. Lennox is fortunate to have him use your product. I had a Lennox before this new one, and found it to be excellent! I wish I could solve all of my problems as easily as I have with your Lennox product and Van Drunen Heating Company.

Louis C.

Extremely professional staff!

Cheryl G.

My old furnace had finally had it and I did a lot of research (on the internet and asking friends) before I decided to buy the Lennox-I chose Van Drunen because they have been in business a long time and have a good reputation-I am looking forward to a winter without any furnace problems.

Sharon P.

I was very happy and pleased with Van Drunen Heating Company, and I would definitely recommend them to my family and friends. The actually allowed me to personally view the two different air-conditioning units in which I was interested.

Linda R.

Everyone I dealt with was extremely helpful and knowledgeable.

Matt F.

I was very happy with both the installation of my furnace and air conditioner. The guy even swept behind my old furnace and asked if I wanted him to move a piece of old paneling that was somehow behind there from the previous owners. They are very friendly and answered every question I had and then some. Great Service! I will recommend everyone who needs their services!

Ida D.

Van Drunen Heating & A/C installed our original furnace and air conditioner back in 1989 when we switched from electric heat in the ceiling to a gas furnace and new A/C. We had excellent service from our furnace which I still have-it needed very little maintenance and now the replacement of the A/C. Van Drunen actually took care of it while I was out of town. They are a very trustworthy company. I am happy to recommend them and the products they carry.

Arturo B.

They’re very good, they did a quality job. The product is very good too.

Ken M.

Van Drunen technicians were very professional, courteous, premier workers. I was very happy with the installation of my new Lennox Furnace and A/C system. I have always trusted the Van Drunen HVAC Company. I grew up knowing the owner even before he started his HVAC business, so when he went into the HVAC business I knew who I would call when I needed service or a new system installed. This is the second heating A/C system Van Drunen has installed for me. Thanks to Elmer, Nick and the whole crew at Van Drunen HVAC.

Peter K.

We like the Lennox equipment we got because it is much quieter than the equipment we had before!

Meileen H.

I found them very courteous and trustworthy. I was able to leave them alone as I had to go out and felt very comfortable leaving my house in their hands. They cleaned up very well and left my basement very neat. I would recommend them anytime.

Mark V.

Van Drunen was very helpful, courteous, and knowledgeable. They answered all my questions, and had excellent communication throughout our transaction. I really cannot think of anything that they could improve on.

Mary S.

I had a Lennox before installed in 1985 and I got a new Lennox and I can’t complain. Van Drunen work is clean, neat, it’s like nothing has been done in my house.

Ted P.

I was impressed that the Van Drunen installer took measurements of the house and asked me about our a/c utilization to determine the best unit to fit our needs. I received 3 bids for the job and Van Drunen was the only one who took the time to learn how they could best fit our needs. I’d recommend them to anyone!

J Lapinski

Finally needed service on my Lennox furnace after five years. Mike Sexton showed up after calling, I can honestly say, never had such great service. If Mike shows up at your home, rest easy, things will be fine. Just shows, Van Drunen is the best.

K. Bell

My boiler was making so much noise it was keeping us up at night. I thought I needed to replace it. Mike was professional and had patience. He traced down the problem, replaced the necessary parts and now we have quiet heat at a fraction of what we thought it would cost. Hats off to you Mike

Larry Peters

Our air conditioning stopped working, Keith came right out on Monday morning for a quote. We were concerned about no A/C because our son was having surgery the next day and would be in a cast 4 to 6 wks. The next day they had someone out to install a new Lennox A/C. This company has installed a Lennox furnace before for us and are always honest, professional, and hard working. Thank you so much!!

Dirk Van Beek

From our initial meeting with Keith to determine what we needed to the installation by Bill we found the experience to be exceptional. Courteous, Knowledgeable, Punctual, and Informative to name a few of their attributes. Bill discovered that improper wiring by our HOA from our A/C to the association sprinkler system was drawing power away from the A/C unit which could void our new warranty and just as importantly , found bird nest material in the exhaust that was forcing carbon monoxide back into our basement which was definitely a health hazard. They could have installed the unit and left but you could tell they cared and as a result we have a fully warranted system and a carbon monoxide-free system as well.

Jeff Brescia

Thank you to Alex for a thorough clean and check of our heating unit. Professional and friendly. Keep up the good work!

Brian Benjamin

We live in Crown Point , In. Called for service on Holiday weekend, Not a problem. Repair was made and we are Very Satisfied! We will always recommend Van Drunen

Armando Aguirre

These guys are top-notch pros! They came to my house and replaced my 1979 unit on the very same day! Very professional. No hidden costs. Very good price! I definitely recommend them!!!!!!

Andy B.

Van Drunen has done multiple commercial buildings and jobs for us, primarily because of their ability- and willingness- to engineer solutions. They usually begin by giving advice to the architects concerning design and layout, and then following through to the details of the project with dampers and vent layouts. They not only know how it should be done, but they have the manpower to do it, and do it well. They work well with other trades and adhere to a schedule. We highly recommend

James L.

Van Drunen Heating and Air Cinditioning employee’s are the most responsible, honest individuals in the business. You never need to be worried about being “oversold”. Their workmanship is impeccable and I cannot recommend them highly enough. Giving them only 5 stars is an injustice.


Justin is a great asset to your company. Please keep him he is a real pro at the service end. Did a fantastic job this morning, and very prompt. Thanks Justin.

Crystal G.

Van Drunen as always has helped with my heating and air. They came out and explained everything they were doing in great detail~this type of service is very important. They go above and beyond with their professionalism. I am always treated with the same amount of honesty and professionalism. Outstanding guys! Three generations of my family have used Van Drunen and every one of them is completely satisfied. Thank you~

Anthony B.

Great Job! Makes an unpleasant expense bearable!

Erwin G.

Amazing service-we’d rate them a 20 Neat Neat Neat #1



John H.

It was a pleasure to work with Van Drunen Heating. They were very professional and did an excellent job of replacing our old furnace and a/c unit with the new units. The workers were very neat/clean and they explained how to use our new system very thoroughly. We are very pleased with our purchase!

Owen D.

Keith Van Drunen has a son who works as an installer. I observed the kid when he was installing a furnace and air conditioner at the office, last fall. He was knowledgeable and knew exactly what he was doing. The father was helpful in picking out the right unit that I needed, not some pricey thing just to make more money. All of this at a good price and now I am sitting in a cool house again. Thanks.

Bonnie C.

Provided service as promised at a fair price.

Stacy A.

I’ve been in my home for over 16 years from the first year of service that I’ve had from Van Drunen Heating. From the first year, the Van Drunen service has always been A1. Apparently, I had one of the old, old models of Lennox and it didn’t fail me…So, of course when it was time to upgrade there was no question Lennox it was. I’m more than pleased!!

Stanley J.

Not much to suggest when you’re the best-just keep up the good work.

Gary M

Van Drunen Heating has people that are extremely professional, very courteous, knowledgeable, neat, and efficient. I have already recommended them to several people and I know two that have purchased new equipment from them. Even when I had a problem with the furnace they responded quickly and resolved the problem. As you can see I’m a happy customer.

Robyn S.

The owner is a wonderful and VERY helpful gentleman. Price for the work that was done was spot on. The gentleman that installed the furnace was professional and got the job done in a timely manner.

Effie K.

There is nothing I could suggest to improve the service I’ve received from Van Drunen. Without exaggerating, I believe I have never received better service from anyone else. Most importantly, I feel their personnel truly care about my well being and about doing a superior job.
