They did a great job. I am very pleased with Doornbos. I've used them over 20 years and never a disappointment. They are very easy to work with and their technicians are very knowledgeable.

I would not recommend door n bos for anything. They gave me a bogus diagnosis for my central air unit. They claim that it wasn’t the CA it was my furnace. After talking to someone I was informed that I didn’t have to have my furnace replaced $8600. dollars later.

They installed a new furnace, heat pump, UV filter and they also added hot water baseboard heat from our boiler for us downstairs and we couldn't be happier. Anthony came out and looked at what we wanted done and gave a price that evening, all the guys did excellent work and they knew how the equipment they installed was to function and operate! Wouldn't hesitate to recommend them!

Have used Doornbos for years and have found them very professional. I recently tried to use the chat feature to schedule routine winter inspection/service and found it very cumbersome. I gave up and called instead. Colleen answered, and I was able to schedule very quickly. Call direct. Don't use the chat.

Had a new system installed on Tuesday. Nick and Jamien showed up on time, worked in the rain, and worked tirelessly to get the job done. Before they left, they made sure to show me what they had done and how the new system operates. First class all the way around. Refused my repeated offers of food and drink - too polite. Oh, and didn't mind our 3 dogs!

They are very organized and prompt. I had new carrier infinity series heat pump and furnace installed, the installation was prompt on time , there was no disruption on my home use during installation. And most importantly they left the house clean after all work like nothing happened. They took time show the operation of the system . Roger was my point of contact /sales and he followed thru every step , even after installation to make sure I get all the rebates I am entitled to.

So Glad to have a new and better air conditioner from Doornbos Heating and Air Conditioning. I must say all the people involved from Dino, Anthony and the installation team was exceptional! Anthony even came back to check up on the new system after it was up and running. I appreciate his honesty and integrity, and polite manner with a sense of humor too! Thank You so much! And the installers had to sweat through one of the hottest days of the summer! Dino was very helpful and knowledgeable. The entire team was exceptional. I want the same guys in the future too! Stay Cool!

Doornbos did an excellent job of installing my new HVAC system. The Doornbros team I worked with was fantastic! Anthony, salesperson, was such a big help and very attentive to my needs.

Anthony Pietrzycki of Doornbos managed the installation of a new air conditioning unit and furnace in my home this past June. I couldn’t be happier with their service! He sent two professionals out and both were installed in one day! The workers were extremely polite and considerate of me. They were hardworking, professional and efficient. Anthony explained everything and answered all my questions and remained involved from start to finish. Even after the installation, Anthony came in person to bring me my warranty and to answer any questions I might still have. I am very pleased with the whole company experience and would highly recommend them! Sincerely, Joan M. Kukuk

I had a new central air conditioner installed today. Everyone I dealt with from the maintenance people to the installers at Doornbos were professional and went above and beyond to do an on time installation as flawlessly and perfectly as I could have hoped, from removing our old unit to installing the new one. I have done business with this company for almost 40 years and once again, they proved themselves to be top in their field. They are respectful of all aspects of your property when they do their work. I highly recommend Doornbos for all your heating and cooling needs.

Richard Lorenz

19:09 17 May 23

The service tech, Moe, was very thorough and courteous. He wanted to do the best job possible. He wanted to be make sure that the unit could handle the summer.

William Noonan

Mo comes to my house twice a year, always him. He is punctual, knowledgeable, and tells me what I might need done. He doesn't BS you. He is the absolute best!!!! Give him a raise!!!!

Anthony Pietrzycki is the salesperson who sold me my new furnace. He measured each roomto determine the size of the unit that would be appropriate. He took time to explain the optionsavailable. He was kind, knowledgable, and patient. I could not be more pleased with my new furnace. I have been a long time Climate Master customer. Since Doornbos purchased C.M.I will now have service and cleaning of my units by them.

Jaclyn Arellano

15:22 01 May 23

I had a great experience with this company. I needed a whole new AC system and Bob the sales guy came out and explained to me what the job was going to consist of. It was a 2day job and they left everything clean and I'm happy with my new unit. The building is old and I have an through the wall condenser in the garage and the air handler was inside the ceiling. It just wasn't ideal for the new equipment. They had to relocate the air handler into my linen closet and connect to the existing duct work and run some new electrical. Chris and Simon were extremely professional and if you want quality work then give these guy a call. I can't say they were the cheapest but I did gets a few quotes prior to making my decision and they were NOT the most expensive either!!! So you pay for quality! I'm happy with the work they did!!! Thanks guys!!!

Wayne Sieben

Mike from Doornbos is the best in the business! His knowledge , skill, and pride in he takes in his work made this the best customer service experience I’ve ever had! Thanks again Mike. I will definitely be recommending to all family and friends!! Happy New Year!!

Susan Haverty

22:36 28 Dec 22

Doornbos installed both my furnace and AC unit a few years ago, and their service continues to be excellent. Just had our annual furnace maintenance and was reminded of how well they treat customers. Appointments run on time, and the office calls with a heads up when the tech is on their way. Once they arrive, they wear shoe covers (booties) in the home. Their employees go above and beyond.A gigantic “thank you” to Dan for noticing a noise our furnace was making during a maintenance visit. Long story short, he caught an issue, picked up a needed replacement part, and fixed it while still under warranty. HUGE SAVINGS! Thank you, Dan!

Lynn Gainer

18:12 24 Dec 22

We were having issues with our heating system and already had someone else come out and look at it, and they weren't able to repair the issue Mike from Doornbos came out and he diligently went through each step of his process to figure out the problem. The fix was a pretty easy one but overlooked by the last technician that came out from another company. Mike was very thorough and explained each step of the process. The cost was comparable to other providers but the service and fix was much better. Mike also conducted a cleaning of our heating unit. We had the service about a week ago and the heat has been consistent ever since. Would highly recommend their service.

Patricia Reed

13:34 17 Dec 22

I called Friday night about the heating issue, and an appointment was made for 7 a.m. the following morning. Mike was prompt and efficient. He explained the problem (lockout and flame sensing issue) well and fixed it in 20 minutes. I'm glad the house is warm again!

Barbara Grossart

23:40 15 Dec 22

We consider MIKE our personal heating and air conditioningprofessional. He listens to the problems and then after researchhe explains the best way to handle the job. Willing to go the extra mile. Thank you Mike!

Paul Janovjak

22:53 15 Dec 22

I’ve been a customer for the past 15 yrs. ‘Most recent Doornbos service completed 5 days ago. The D-tech completing that service was Mike D. Doornbos’ equipment pricing is competitive, not earth-shattering. But what sets them apart (from competitors) is their (tech) customer service. Mike D. makes the Doornbos-brand shine brightly. In the past 10 yrs of working with him, Mike D. is friendly, professional, honest as well as very knowledgeable.‘Not sure if they do, but I would hope that the bosses & owners realize the huge asset Mike D. is…to the Doornbos name..ie..company! Mike D. is absolutely worthy of this 5-star review!!

Lydia Koch

23:02 14 Dec 22

We have been loyal customers of Doornbos for more than 20 years. Not only have we had repairs done, but we have had furnace and air conditioner units replaced twice. The office staff have been friendly, and very helpful. A special shout out to Mike Donahoo who has always provided outstanding service, that is why I always request Mike because I know he will take care of any problems I may have.

Robert Krause came to our home in early Oct. to give us an estimate for a new furnace and air conditioner.We had 2 other estimates already, and decided that Doornbos was definitely the "top" company to deal with. Bob was very professional, and made us feel good about our decision. The installation took place the following week. Nick and Jamien arrived on time and worked so well together. They werevery hard workers, and are also "well deserving" to be commended for doing such a fine job. They explained everything thoroughly, and made sure all questions we had were answered. We want to say that Bob, Nick, and Jamien are all assets to Doornbos, and we have highly recommended them to others. The sheet metal work between the furnace and the plenum was an outstanding job! We have had our old units in for 49 years and hope the new ones will last that long! (HA)We appreciated being treated so kindly, and we thank you for a job well done!

Tim K

00:27 21 Oct 22

We are new homeowners and the baseboard radiator in our bathroom wasn’t working and then it developed a leak. Mike showed up quickly, fixed the leak before we had any serious property damage and got our radiator back up and running. It’s nice to have heat in our bathroom for the first time since we moved in. Thanks, Mike!!! And thanks, Doornbos!

Mary Kaye Green

16:19 07 Oct 22

Just wanted to say what a great guy Robert Krause was in helping my husband and I choose a new furnace and air conditioner in our home. He was very professional and listened to our needs. He is very knowledgeable and takes care of everything. He was not pushy at all and answered all our questions. The installers were great Jamien P. and Nick C. were very professional and didn't leave a mess. They showed us how to use the thermostat and left all the manuals in a nice container attached to the furnace. I highly recommend Doornbos Heating & Air Conditioning.

Can't say enough good things about this company! Bob Krause came out to do the estimate and was wonderful! He gave us options and helped us understand each of them to make the best choice. He even came back within 30 minutes of leaving so we could sign the contract! The work itself was completed within the week by Nick who was also wonderful! We had asked about getting our furnace cleaned while he was there but Nick could not do the work so he called his boss and his boss was at our house within a few minutes to complete the cleaning. Doornbos will always go the extra mile to make sure their customers are happy and that we are. Thank you!

Tried to secure their service for an ecobee installation which we bought from Home Depot. Technician came this morning charged $99 for showing up. Said charges might be more depending upon his inspection and could reach $400 plus. Tried to tinker with the wirings figuring out which goes where and maybe after 40 minutes - said can't do anything about the wirings. (Mind you, our HVAC system was installed by this company that's why they were the ones I called for service) Then he quoted $275 but I told him you basically did not do anything and did not change anything. Then just charged $198 for inspection. BE CAREFUL! If I did not question, technician won't drop the fee.

Henry Kalis

15:45 29 Aug 22

Hats off to brothers Simon & Kristoff for their impeccable work on the replacement of my 22 year old heating/ac systems with a new Carrier 3.5 ton high efficiency unit & a 2 stage furnace. Having a trade background, I expect quality workmanship & they surpassed my expectations. On time, courteous, knowledgeable, & efficient. At days end, they checked both systems to make sure everything was working properly. They did the job once & did it right. You can't go wrong with these guys. I also use Doornbos for yearly maintenance of both systems.

Amber Beyer

Roger was the 1st person who came out to walk through and do a thorough inspection of our home in regards to installing a Space Pac high-velocity AC unit in our 105 yr old home. He came back two more times after we received the quote, to go over specifics in regards to the installation and placement of the equipment. Jamien & Nick were seasoned, experienced professional installers. They answered all of our questions, arrived on time each day and did a professional job. Mark came out on the last day to set put the panel and he explained the operations of the new unit to us. We were well taken care of by all involved and my husband and I would recommend Doornbos Heating & A/C to anyone looking for quality products and professional service. Well done gentlemen!

The company was trying to charge me 1500$ for a part that cost 200$ and a fee of 239$ to come and check the problem. Bringing me to a total of 1800$ for visit, parts and labor. The person that came said if I signed up for the yearly maintenance they will only charge me 900$ For the work they were about to do. This price is a rip off to home owners. I will never again call this company for work!!!!!!!

Contracted for furnace cleaning and maintenance. Their technician, George, is hands down the best professional I have ever dealt with. He found a problem I was unaware of and fixed it at a reasonable price. I can't recommend them and George enough!

22:06 11 Nov 21

Doornbos is a really professional business. They installed our new furnace and air conditioner and did a great job. The office staff and all the installers went out of their way to make sure the installation was done in a timely manner. I would highly recommend them for all of their heating and AC services!

Janice Morris

12:40 01 Nov 21

I have been having the same issue several years in a row. They come out, charge hundreds of dollars and the issue is only fixed temporarily. The tech is lovely but paying to resolve the same issue repeatedly is not ideal.

I highly recommend Doornbos - they recently installed a Space Pak AC system into our almost 100 year old house. The team was on time, friendly, super clean and great at problem solving and consideration when working through solutions to get the complex system incorporated into our home. I highly recommend Doornbos!

I can't say enough about the company & the technician.He also wore a mask. Thank you Doornbos!
