A+Derr was by far the best company that responded to our families AC needs. Our AC went out so we called 8 companies to get quotes for a new Central Air unit. A+Derr went out of their way to try and get us scheduled as early as possible to get a quote for a replacement. The other 7 companies, only two showed up for quotes and one was a day late. This made me really want to go with A+Derr because if something goes wrong you want to go with a company that actually shows up for an appointment. A+Derr sent out Josh to give us our quote and he not only gave us our best price out of the 3 quotes we received he gave us the most information. He walked us through all the ins and outs of an AC and furnace as well as the work they would be doing. He was extremely knowledgeable and put up with our lack of knowledge and helped educate us. He was so good we decided to replace our furnace as well at the same time. When it came to installation we got Texal and Tony as out field technicians and man were we impressed. Not only were they clean and tidy, they made sure they kept our house spotless as well. They laid down drop clothes and made sure not to dirty up our house at all. They also made sure the work was done neatly so the units would look good. So even though nobody looks at a furnace or AC they wanted to make sure the duct work looked good. That is awesome! They did great work and I am so happy with it. Texal even went out of his way to come tell us when he was going to make more noise since me and hubby were watching a movie while they did the work. I can't recommend A+Derr and its staff, Josh, Texal & Tony enough. read more

*we had our furnace and ac installed today by Nick and another tech who both did an amazing job! It's an awesome system and we are SO happy we went with A+. They have been so helpful and every technician that has helped with our issues and installations have been incredibly knowledgeable and very good at their job! We appreciate the amazing service!*If I could give 100 stars I would! This company is amazing, fair and knows what they're doing. I am so relieved to have our problem solved after months of dealing with another HVAC company that wasn't doing a good job. Shawn is awesome, knowledgeable and incredibly good at his profession and spent the day making sure our situation was taken care of. He was honest about what our next steps should be and made sure to thoroughly diagnose the issues! I am so happy and excited to have brand new systems installed. Our furnace is old and we were putting band aids on issues without fixing the main problem & spending too much money. Pricing is VERY FAIR and the new systems are amazing! We have been so stressed not having heat for 2 months & I can finally take a deep breath now! No more having to deal with constant issues. It's also great that we're improving our home value. I'm so happy we used A+ and I will be recommending it to everyone from here on out. read more

Very pleased with the service we received. I requested an estimate on their website on a Wednesday evening, Thursday morning they called to scheduled an appointment, the sales person came out that same day, he was very professional and polite, he was very descriptive on prices, equipment and payment options. The day after he came out, we got a phone call to schedule our installation. They set us up for four days later but ended up coming out earlier after calling to check out our air situation, which wasn't working hardly at all. The installers were very professional, laid plastic on the basement stairs and cloths along the basement for walking. They cleaned up after working, went over the furnace and the A/C unit with us, discussed operations on the new thermostat, asked if we had any questions, they were very knowledgable on the equipment they installed. Very happy we went with this company! read more

I have a contract with A Plus Derr and am so glad that I do. They get to you pretty quickly if you have a problem with your A/C or Heating unit. I used Derr in the 1970's and 1980's before I moved away -- and was so happy to see the Derr name again when I moved back. I just had my annual A/C checkup and all was well. The house is 13 years old and I am the only owner -- I would recommend this company to anyone. They stand behind the work their servicemen do and their employees are not only good at what they do but very good at explaining it and doing what they say they will do. I just had Dylan service the A/C this time -- first time I had met him -- and he definitely is exactly what I have come to expect from this company. Thank you A Plus Derr and thank you Dylan for working out in this 99 degree weather with NO complaint and no slacking in the service you gave me.! read more

What are great company to hire! I was impressed with them the moment they gave us an estimate. Now I understand why so many of my neighbors have A+Derr signs in their front yard! I asked several of them if they were satisfied with the service and quality and heard nothing but great things. :) The guys that installed it Kyle and Dave were very respectful to me and to my property. My husband was down stairs sleeping and they tried to keep noise down and did a pretty great job as they did not wake him up. We have had a lot of service and repair people in our home and these guys were just about the most respectful and CLEAN we have had. Usually after repairs I have to go in after they leave and re-clean the area but not with this group... and here is the biggest thing... they also had the best price too. read more

I had to have 2 sets of A/C and Heating Units replaced. The work took 2 full days. My technicians on the job were Texal S, Scott A and Cameron. I was informed what was going to happen and that they would clean up afterwards. Well I was very impressed with these guys! They were knowledgeable , professional and helped me understand how to work the Nest, working thermostat on walls. I had to leave to work and I felt very comfortable with them in my home. They did call me and let me know when they were finished. And showed me how to change the filters, and operate the Nest. My house was spotless after the work was finished!! Thank yu guys!! Texal S, Scott A and Cameron. Your work was excellent!! A+ Derr is highly recommended !!! read more

Brent, Alex and Daniel installed a new furnace and air conditioner at my home today. They showed up on time, were very polite and cleaned up after themselves. We were very pleased with their service. I was told twice last week that it would take the entire day; they were finished and ready to go by 2p.m. I already have a check-up appt. set for next week to make sure the unit is working properly, I would recommend them highly. We have six small dogs that bark constantly at strangers (but do not bite unless provoked); and no one complained; and they were very careful not to let them out the front of the house, as I have a couple of runners. Answered all questions and explained new thermostat. Very pleased. read more

bought our house 35 years ago. just replaced our entire heating and air condition today. James and kyle where great. polite professional and answered all my questions. I'm really impressed with these new furnaces. quite and 96% efficient. our old furnace was heating the garage where it was, not in the house where we where. can't beat the price and the warranty is A plus. I would say to anyone thinking about heating and air. Call A-Plus Derr they can come out analyze your home and give you an honest inventory of your system. Glad I got this done before the cold winds of winter are blowing! I would recommend them in a heart beat! Robert L. Bihm read more

There is a reason there is an "A+" in the name. Had an issue today and our cooling system shut down. I did the little quick checks and it was nothing I could fix, So I called and asked for a service call. Wow ! had a technician at the house in under 30min. Found the problems and was done in another 15. Best service and personality I have seen in any business in a very long time. I can tell they place a lot of focus on customer satisfaction so I decided to sign up for a regular service plan as well. BTW this was my decision and not an up-sale from the tech. Highly recommend these guys.... read more

Danny M and David H came out to service our 2 units. Arrived on time (actually 10 minutes early) and were done before I thought they would be. Very polite and professional and answered all my questions. Great guys! My only complaint is the price I was charged for freon. Now I know Danny and David don't set the price for freon but I believe someone at A+ Derr does. I was charged $100/lb and if I had a license to buy this I could buy it for around $25/lb on Amazon. read more

Amazing service, once again, from the helpful staff and technicians at A Plus Derr! We had a major issue with our air conditioning due to a power surge during last weekend's storms and Cole Byers worked so hard for us to get the air back up and running. They saved us money and still gave us 100% of the hard work and customer service we have come to expect from them. I highly recommend A Plus Derr, and especially, our hero, Cole Byers!! Thank you!!!! read more

I am very pleased that I had my HVAC system installed over the summer with A+ Derr and that happiness carried over with the routine maintenance recently performed by technician Scott A. Changed the filter and tested all the components. He also was more than accommodating when I had to leave the house to pick my kids up from school. Wasn't an issue. I can't recommend them enough! read more

We've used A Plus Derr for 12 yrs and can vouch for good quality service. Justin did an awesome job today servicing our unit and also taking care of an ongoing issue with the blower/dampers and we appreciated the extra time and care he took to get this accomplished! We will continue using A Plus Derr Heating & Cooling! read more

My experience with A+Derr has been excellent from start to finish. Barney did a great job with the quote. He was very knowledgeable and thorough. Dylan and Josh did the installation on the heating , air and water heater. They did a great job and were very professional. I would highly recommend A+Derr. read more

Marcia came out to clean our A/C and check the furnace since we got a new unit in April. She also took care of a vibration on the condenser. She arrived early for the appointment, which was great. She completed her tasks quickly and efficiently, and was very friendly. Thanks Marcia and A+ Derr! read more

Scott Avery came out to my house and competed same day service on my broken AC unit. Scott was very professional and knowledgeable and was able to get my house cooling down in a mater of minutes. I would recommend A+Derr Heating & Cooling for all your HVAC needs in Newburgh and Evansville. read more

Our 31 year old heat pump finally went down, and these guys had us a completely new system up and running for a good price inside of two days. I was very impressed with how they explained everything as well as the workmanship. I will not go with anyone else for heating and air. read more

Mark was very friendly, professional, and efficient. He answered questions we had and as new home owners it was very helpful.He also advised on the best course of action. He solved our immediate problem and also directed us for any future HVAC needs. Great job, great service! read more

From the day we met John to talk about a new system and throughout the entire process, we could not have asked for better installers and follow up personnel. The installation job was so well done and my questions answered immediately. Great job, keep up the good work!! read more
