Reviews of local pros in Arnold, Missouri

I called them on a Saturday and within 30 minutes they were there to get me fixed up. I told them we had a 2 week old baby and a 2 year and our air conditioner wasn’t working (92 degree day). I was expecting to spend an arm and a leg with it being near 5pm on a Saturday but I did not their prices are very reasonable. All in all Matciante Diversified just found a new customer for life and I would recommend them to all friends and family!

I called on a Friday afternoon and received service within an hour. The HVAC technician (Ken) Was very helpful and professional. Within an hour he had my broke down A/C up and running!! Thanks for the prompt , professional service. George Compton

We called at 600pm tonight and Bruce was here by 715. It was a quick fix which we were very thankful! And it was super reasonable. Very happy with the service and Bruce was great!!! We found our ac/heating guy! Thank you!

This person was one of the most unprofessional contractors that we have attempted to work with! He stopped by the house to estimate a repair. My wife was home and she wanted to talk to me about the cost and in the TEN MINUTES it took for her to call and talk to me because I was at WORK. Mario LEFT abandoning the project due to impatience! Very unprofessional! Then when I called to let him know how unprofessional he IS he attempted to tell me how he tried to do me a favor but because as he put it "I didn't know you don't have no money" he couldn't wait for my wife to get back to him! I will NEVER use this service institution!! As a lesson; you might want to consider working on your customer service and professionalism!

After having Marciante Diversified to my house for a furnace issue I mentioned wanting to get A/C and heat installed in two rooms of my house. They suggested going with Mitsubishi mini split HVAC systems. Marciante is a Mitsubishi Diamond Star dealer. I did some research and found that these systems were highly rated. I asked for an estimate and decided to go for it!
I can not begin to tell you how happy I am with the systems and the installs! Their attention to detail and the quality of their work is outstanding! They do what they promise to do. Plain and simple! I would recommend Marciante Diversified for maintenance on your home HVAC systems as well as Mitsubishi mini split installs.! Thank you Marciante Diversified! You've got my business!

My AC went out late in the evening. I called around 12:30 am and they sent Bruce out. He arrived within the hour like expected and was in and out in 15 minutes. Very professional and polite which is great considering it was 1am. I really appreciate them and will definitely use them in the future!

Had a great experience with Bruce! The day started with a 5 and a half hour drive home from chicago from a small vacation, as you know a drive alone can stress people out and the last thing you want to come home to after leaving for a few days is a home with no air conditioning. Well... thats how we were welcome home, with very short notice we called and without a single problem or one bit of attitude, Bruce was sent to our home *mind you its 1am...* needless to say he was extremely nice, and overall understanding that these things happen, and he said he knows it is next to impossible to sleep when it is hot.
Bruce thank you again for being the only person of a handful of companies to step up to the plate, and go above and beyond to help us out with such short notice and such a late hour... it honestly means alot, the customer service was stellar, and i will be sure to recommend you when i hear anyone having problems..

We received several bids on a new AC and furnace to replace our 26 yr old system. I’m so glad that we awarded the job to Marciante Diversified. He did not provide the cheapest bid, but more importantly, provided the best quality in his work! This is far more important when it comes to a big investment on equipment that is run 24/7-365 days a year in our household.
The entire crew, Mario, Brad, James and Vito were extremely polite and professional. Their multifaceted talents shined as they went above and beyond and worked long hours to make sure the job was done right instead of cutting corners.
I highly recommend them for any installation of your HVAC system.

Extremely great service and arrival time was very quick. Bruce, the tech who arrived to help us after hours, was extremely professional, knowledgeable and fixed our problem within minutes of arriving (he probably knew how to fix it before he arrived after hearing the issues we were having). I will recommend this business to anyone and everyone I can. Thank you for your help, we now have heat!

Mario installed my furnace and air conditioner on a very, very hot day. He gave my daughter an estimate on a new furnace and air conditioner and the very next morning installed it. He put a new roof on my house. He installed a new wood insert for me. I am very, very happy for all that he has done for me. I highly recommend him to anyone who is in need of repairs.

These are the nicest people. Very responsive. Mario came and looked over my system needs, gave me a quote and within a couple of days I had a new A/C unit and furnace. Installation in one day. Just in time before the heat wave. Working like a dream. Thanks.

They were absolutely amazing. They came for an emergency service. While here for that he worked hard and fast on our very old heater to get us heat for the night. Then called in the morning just to check on us. We ended up get a new heating and cooling system. They were able to come in the following day and get it in. It was absolutely amazing. They are the best. Would recommend to everyone I know. Thank you guys so much.

If you want a friendly reliable company Marciante is the heating and cooling company for you! Margie is the first person you talk to when you call! She’s AWESOME! And if you get Ken the service tech your getting the BEST! He is so knowledgeable! He finds the problem and fixes it! No hassle or fake problems. This company is so honest! Give them a try you will be impressed with their service! I highly recommend them! Thank you for your Awesome service! I will tell everyone I know about your company!

Mario & Vito were very responsive once we determined that our furnace was shot. They provided equipment options to meet the size of our home, energy efficiency and price.
They didn’t pressure us at all & we selected the best furnace & HVAC that meet our needs. They provided us with space heaters to provide heat until we get get the new furnace installed, which was very quick considering the furnace went out on a Thursday & they installed a new one on Monday. They arrived on time & were very professional. They made sure we were happy with the product and service we received. We are so glad we selected Marciante to install our new Rheem system.

This is my second time calling after hours and getting a very speedy response from the Marciante Team! They made sure my family and I were comfortable until they could get the correct parts ordered and come back to install. Prices are more than comparable and I always feel comfortable having them in my home. Their Team are very respectful, honest, caring and nice. THANK YOU!!!!!

These guys are great! Mario is very upfront and honest to start the experience. Bruce, Vito and James are awesome. They are all clean-cut and professional in appearance. Maria is a sweetheart when you call into the office.

When you invite strangers into your home, you never know what to expect and these guys are funny and knowledgeable. They get the job done while not making it awkward! They specialize in heating and cooling and do a wonderful job at it.

However, the diversified stands for a lot. They have done a lot of different jobs for my family and aren't afraid to take on just about any task you throw their way. If it's not something they are familiar with, they always know who to call in and get it done!

As a local real estate agent, they are wonderful people to have in your corner and I would definitely recommend giving them a call!

Recently used Marciante Diversified complete a full furnace and AC replacement project. While I was drawn to them because of the highly rated Rheem equipment, the entire team won me over. Mario is fantastic at explaining how a system works and what makes sense your home. Margie is great at communicating, especially with scheduling. And the installing team led by Vito did a fantastic job, left our home clean each day, and did a fantastic job. Highly recommend you reach out to them for any work you may need done.

Bruce is based out of North County and we live in Jefferson county. We called to have our furnace fixed in the middle of the night. He was very quick to respond and come out. He was very friendly and fun to talk with while he fixed our furnace. Very informative as well. I definitely recommend him for your furnace needs.

Professional and fixed the problem!

Jeremiah is extremely professional, knowledgeable, and honest.
