Simply put they were perfect from beginning to end! They were on time and through with explaining everything when completed!

We were charged $80 for a discharge fee. Nothing was done. It was an absolute waste of our time and money.

@DEITERBROS FUEL. #willneverusethemagain Made an appointment for a cleaning. Was told my furnace was under warranty so no charge. Once they finished cleaning it I was told I owe over 500. Called the office sure it would be taken care of. The manager told me I was miss quoted and he would bring the rate down to just over 300. What a rip off. I will never recommend them. Bait and switch. read more

VERY poor communication. I had to continually pressure to get the work I was promised and quoted. I needed to show the quote to the install team to indicate what was promised! They were not briefed at all on the job. Wrong materials were routinely sent with them. Insufficient manpower sent to do the job right and on time. Extra visits were required. Field team was good but hampered by poor communication with salesman and install manager. Salesman was BAD... hear he has since left, but ruined Deiter Bros. reputation in his wake. read more

Terrible service? How about NO service. Deiter missed a scheduled, non-emergency service call to my home. (scheduled one week in advance, I should add.) No call from them, no follow-up. I think that deserves one star. You decide. read more

Terrible service! Had to call several times when a thermostat that they installed malfunctioned. After 5 phone calls I finally got someone to come out and replace it - THEN, they programmed it wrong. My heat was air conditioning and my AC was heat- to my surprise when I turned on my air, it got up to 80 degrees. After 2 more calls someone finally came out and fixed it. The topper......2 weeks later I received a bill for $105.02 for LABOR ! When looking for an HVAC company, look past Deiter Brothers! read more

Terrible communication in this company. I would never recommend someone use them for fuel tanks for a generator. It's like being a babysitter to make anything happen. read more

We used Deiter brothers in April of 2019. To take out a old radiator and replace with a baseboard heater. The salesman Bill Boyle came to my house and literally just looked at unit to replace and looked in kitchen and bathrooms & dining room so he was aware of what I wanted . Quoted me $1700 for a new baseboard heater. All is good. They came out to do the job on April 5, and upon arrival the technicians were floored on what they seen. They said they don't even know where to begin or where they informed by the salesman on how detailed this job was going to be. I left for an appointment and my boyfriend was home & they told him the pipes where going to be exposed and there's nothing they could do about it cause the old radiator was removed and pipes were cut. We told Jeff before he left we wanted a call from Mr Boyle and that never happened . When I didn't pay the balance then they talked with us but me Boyle never came out to see his mistake on his quote . He sent another person Andrew who stated that Bill is clueless and this is the shit they have to clean up after all the time !! Andrew stated they could cut up my floor and or walls in my basement ( which was just redone ) to fix it but it would cost them more in labor and time to fix it that what I owed to Deiter Bros. He was supposed to have Bill contact us and that never happened .. Deiter brothers then ran my credit without my authorization !! When I spoke to Bills manager he said he would call me back!! Well no calls back !! And surprise then I get a letter from the magistrate and they are suing me !! But we can't go to magistrate they filed out cause the Deiters own the building magistrate is in . On our hearing date they literally brought everyone with them . And surprise they lied under oath!!! i lost and now owe they for the job which was done and is the worst job ever and can't believe they call them selves professionals !!!! Please don't use this company !!! They are liars and their work is not professional !! How you can own a heating company for all these years and leave a job like this is despicable !! They should be ashamed at this job !! Cause I'm even embarrassed . Please shop around and don't use them !!! read more

See all

I have had positive experiences with this company in the past. However, recently, they sent someone out that didn't know how to fix my furnace problem. He worked on the furnace all day, telling me I had contaminated my oil. They finally sent a 2nd technician right before 5 p.m. (because I called and complained that the guy doing my furnace had no clue how to fix my problem) and they got the furnace running and ran out the door (the furnace ran for 5 minutes after they left and then quit again). Before the guy left, I rendered payment for that bill - in excess of $400 - but had to schedule another guy to come out. Experienced tech comes out, and fixed my problem (busted oil pump) in about 30 minutes (for another $350). This tech said it was an old pump and it died, and made a face when I told him the previous guy was convinced it was contaminated fuel. So, I complained about my service to the VP of Service, because if the first guy had known what he was doing, I'd only be out $355, instead of $760. Who said, in essence, "You're wrong, our guy was right, tough noogies." The straw that broke the camel's back was that I rendered payment for all bills at the time of service...and they accused me of not paying the bill I contested (the invoice has a credit card number ON IT!) and threatened to send me to the magistrate. This is how you take care of a customer who spent nearly $800 with you in three days? I will tell EVERYONE I know to avoid this company. They clearly don't have a concept of how to properly handle customer issues. read more

Wow. Our house had an A/C problem and I called Dieter Bros. this evening after hours. I got a call back from Bob, the tech on call, within 10 minutes and he was here not long after. He diagnosed the problem quickly, fixed it and we've got cold air again -- less than an hour since I called. I lived in Atlanta for many years and though I was very happy with our HVAC folks there, we NEVER had such prompt service. Kudos to Bob and Dieter Bros! read more

I have had very positive experiences with Deiter Bros. They are always very punctual, professional and informative. They are patient with my questions taking the time to explain everything to me. They have never let me down and are great in my book! read more

This review concerns only the billing process. Deiter Bros does not have a transparent billing system. We bought oil and a service plan. To have access to these services Deiter Bros does a credit report check on you because basically if you do not pay your bills on time, they will start charging interests. The service plan was imposed on us by the company. We wanted a full coverage service but they assigned to us the minimal coverage (perhaps because our furnace is old? That point was never clarified). The assigned minimal coverage service plan does not include parts. When a technician came to perform service, a part had to be replaced, and we had to pay it. OK. The technician gave us a receipt with the annual service plan fee + the cost of the part. He told us that in a few days we would receive a bill by mail or by email. We did receive a bill by mail. We paid it promptly (and we did not realize that they had only included the service fee and not the part cost!). Then, oil was delivered. A receipt (or bill?) with no instructions whatsoever of how to pay the bill was left in our door. According to their policies, if one pays within the first ten days, they charge a lower fuel rate. We wanted to pay on time, but how? We waited a few days, expecting a bill by mail... As the discounted rate due date approached, we called the company and they told us that in addition to the delivered fuel we owe the part! We did not know. Why Deiter Bros does not simply send you a bill by the mail or online after each service is perform? I suspect they do not want clients to pay on time, in order to start charging interests or higher fuel rates! read more

I'd give them six stars if I could. Our A/C quit and both indoor, outdoor systems needed to be replaced, and of course all during the hottest week of the year! Deiter Bros fast, courteous and accommodating with our onset of issues. Thank you to all the guys that came out to the house and to the entire staff for your friendliness and professionalism! Highly recommend to anyone needing service... read more

Deiter brothers delivers propane quickly and makes purchasing it easy online - which is a huge convenience. However, they are consistently overpriced - perfect example is, right now they are selling propane on their site for 2.67 a gallon. Fairclough in Newton, NJ is selling propane for 1.95. What gives? Seems to me like they are ripping people off... I was a greenworks customer and I'm getting away from DB as soon as I possibly can. I think I understand why they show up so fast if they're making this kind of a profit. They're modeling themselves after amerigas and suburban - that's what it looks like to me. Get propane somewhere else. read more

Bill R. was very thorough and friendly. The work was done quickly and completely. Bill showed me before and after pics and explained everything to me. Very happy with my first service from Deiter Bros! Thanks again! read more

Did a nice job installing a gas furnace a few years ago. Although they showed no interest in setting up electronic info readout on the front of the furnace. Wrote that off as they just weren't interested since I wouldn't be a future oil customer of theirs. Techs seem competent and friendly for the most part. Receive the monthly newsletter which regularly disses people (like me) who switched from oil to gas, back when oil prices were skyrocketing. Funny thing is, Deiter Bros had no problem taking my 8500 to install my gas furnace. Gas prices could quadruple and i'd still be lightyears ahead than if i had stuck with oil. In fact, the savings the first 4 years alone paid for the furnace. read more

Last year my A/C died and Deiter sent a Tech within a day... he had the replacement part on the truck so all my pets were saved. It was becuase of this that not only did I purchase a 1yr service contract, but also recommended them to a few of my neighbors. Recently, we all had our units inspected and serviced but a few weeks later, my neighbor's condensate line was blocked and flooded the dining room and bedroom. The part I'm pissed with is that they CHARGED her $80 for a service call - not only is the call included in the contract, but the kid they sent said nothing is blocking it... this was after a contractor had inspected the area and shook the blockage out. Conclusion - DO NOT PURCHASE a service contract... they'll charge you anyway AND not perform the preventative maintenance! read more

The annual boiler clean for maintenance went smoothly and professionally. The crew at Deiter Brothers is consistent and never leaves you guessing. Thanks for the consistent excellent work since 1999. read more

My experience with Deiter Bros. I called about a heating system, the company sent the owner's son to give me an estimate The son came and gave me an estimate with two options, Now this gets funny. The son told me he can save me $1200 on the job if I used him and his cousin to do the work on the side, YEP on the side. He told me he would give me his cell phone number if I had a problem with the heater and would guarantee the heater for 1 year. Hmm, Fecking his father out of business. FUNNY SH$T. I told him no I didn't want to do it so I paid the full price. Next I needed a cooling system so I call Deiter Bros again and they sent the son to my home again, LOL. This wee FECKER TRIED to Feck his father again out of the job, anyways,he wanted to save me $1500 this time around, again I say no, So I paid the full price by check, but while he was at my house I talked to the son about getting a new water heater, same thing again. wanted to take the job on the side. so I said no again. I wanted a top of the line water heater so he charged me $1200 for it, so I paid for it cash. now for the rip-off part The son calls me and tells me he will have to put the water heater in on a Sunday, RED FLAG WENT UP!! I called the installation department and checked on the water heater, I already knew what the answer would be they have nothing about putting in a water heater at my home,That wee fecker and his cousin were going to put it in themselves Well I decided to call off the whole deal and not have them do any more work for me. I told the son I wanted my money back, He told me because I called off the deal I would have to pay a $300 restocking fee, because it was a special order. O well I lost $300, They lost more in future money from me. I'm entitled to my opinion and so are you about using Deiter bros fuel they may have good service but putting up with BS and getting Fecked outta $300 by the son, It just isn't worth doing Business with them ever again. I did read in the newspaper the son embezzled close to $130,000 from his father and was in jail, Karma is Funny, always gets ya in the end. The Del fuel man also spilled about 5 gal of heating fuel in my yard but no big deal on that, sh$t happens. read more

We have a System 2000 boiler which also creates our hot water supply. In May of 2012 we had another firm repair our system when we lost hot water. It took them over 2 weeks to fix. Six months later and we lost hot water again, this time it look lke a leak in the hot water holding tank, after having Eric from Deiter Bros come and look at he, he not only fixed the leak but found that we had the same issue as six months ago. Not only did he take care of the problem but he took the time to fully expain the issue to me and too the other contractor, so that I was able to get partial reimbursment from the original contractor for the work that Eric had to redo. In addition he was very professional and we would recommend him our friends. read more

This company has been wonderful! They provide very quick service and knowledgeable staff. We live in an old house with steam radiators and have learned a lot about the system from Rev, Rick and the other service people who have come. Affordable, prompt and very helpful - we'll keep calling! read more

We're staying in a house in the Lehigh Valley that lost power due to Hurricane Sandy. After the power came on the heater didn't work. Steve came over and immediately diagnosed the problem with the heater and fixed it. And he took the time to educate us about our heating and hot water systems. Nice guy and very knowledgable. read more

They sent a young kid out to check why my oil furnace was creating smoke, but he basically had no idea. I then received an invoice for $100, and when I called to say that he didn't do anything, they asked if I expected someone to just come out there for free. Well, I've checked their website, and it does say free estimates, but I didn't know it then. A week later I got a notice that they had filed a suit at the magistrate, which btw is located next door to their business. Rather than deal with the hastle, I agreed to pay the bill, and they demanded that I pay the court fees as well, all for zero service. They are really rude on top of it. read more

We have been very pleased thus far with the service Deiter Bros have provided us. Special shout out to Rev Apgar who serviced our furnace. Courteous, knowledgeable, and very helpful guy. Thanks again. Will highly recommend Deiter Bros. read more
