They responded quickly by phone late on Sunday night to a flooding situation in my basement and guided me to shut off the water to my water heater. Oscar came first thing Monday morning to assess the situation and returned with the new unit and Thomas. They worked for several hours to install unit, explaining how it all worked. In addition, Thomas used my shop vac to vacuum up most of the standing water. Above and beyond!!! read more

We have worked with T.F. O'Brien since we had our ductless AC system installed in 2021. They did a great job installing the system and in seemlessly coordinating the removal of in-wall air conditioners. In the years since we have had our annual maintenance visit and any work necessary has been done professionally. All of their technicians are knowledgeable and pleasant - never had a problem. They take great care when in a customer's home to be tidy and if anything needs to be moved to access the unit they are working on, it is moved with care and put back when they finish their work. They are a family run company who truly cares about their customers. read more

Robbers! charged 18 k and did not change appropiately the Ac and heating system. Stay away from them they do not know anything about installation. We request to change the whole system and had been working on it for over 2 months and still haven't get it done. RED FLAG! read more

I needed to put in an emergency call because my boiler stopped working. I had no heat in my entire house on a cold day & called T.F. O'Brien that states they are available 24/7 for all repairs. I spoke to a robot that told me the next available appointment was in 2 days. Very dishonest advertising. Very disappointed in a company that brags about excellent service. read more

My AC wasn't working. I called T.F.O'Brien which installed my ductless unit. Lucky for me, they sent Oscar Flores. what a gem! He was patient, kind and immediately knew what caused the malfunction. All the personnel at T.F. O'Brien are great, but if you need an explanation on how to operate your AC ask for Oscar Flores. MMC read more

Update: Units installed April 2024 Previously had five wall mounted AC units. Switched to six Carrier mini split units as part of extension and other renovations. July 6 - August 6 PSEG usage was 31.5% lower than same time last year. August 6 - September 6 PSEG usage was 40% lower than same time last year. This is in spite of adding a second back up refrigerator in the basement. Great investment in our home! read more

I'm so lucky I realized how expensive these guys are. Double the price of the other ones and not amenable to doing anything different

T. F. O'brien installed Diakun mini splits in our home in 2015, Invoice stated it had a 12 year warranty on parts, 2 years on labor.. However, when the refrigerant started leaking after the 4th year, we scheduled a service for finding the leak on the system. We were charged $500 for two servicemen to locate the leak. They said they couldn't find it, however, we were still required to pay the $500. I thought the customer service was extremely poor, to have never received a call from the office for any type of remedy of this issue..We continued to have the refrigerant pumped in by another company until we decided to replace the whole system..these units should last between 15-20 years but we got 8 1/2 years. Also, they charge $269 for a service charge, just to walk in the door for a look, which I think is too high. Thankfully we are using another company moving forward! read more

I came home late Wednesday night and discovered water leaking from the ceiling underneath my AC Unit. The next morning I called TF O'Brien and within an hour and a half, a technician was at my doorstep. Nick B went right into the hot attic and crawled through the space to the unit. He discovered the problem and took corrective action. Thank you to the TF O'Brien team for getting my unit back on so we can enjoy the comfort of the cool air away from the oppressive outdoor heat. read more

I called T.F. O'Brien because I was having issues with heat not remaining in my radiators on my 2nd floor. A tech came out, drained my system, and changed 3 air vents. I was charged $700 ($150 per air vent WITH A DISCOUNT, when they are $80 for a 3 pack on amazon). The radiators heated up, and the tech left. My instructions were to let the system air bleed at a high temp for a few hours, which I did. Shortly after setting the system to a normal temp of 73, the radiators upstairs were ice cold again within 20 minutes. I'm back to running my electric heaters so my wife and I don't freeze during the night. I called back and said that my original issue was not resolved and did not want to be charged a return visit for labor since this should have been fixed. I said parts I understand, but I'm not paying the base $250 which is ALREADY higher than most other companies. The condensing young man would not guarantee that I wouldn't be charged because the problem could be unrelated to the last visit. I said the last visit's problem was that it doesn't work properly, and it still doesn't work properly, how is that not related!? I explained that I made this issue clear when I made the appointment and when I spoke to the tech. He told me, all it says here is that you were scheduled for a tune up with nothing about my situation. He then told me your boiler might be going out because it's 15-20 years old. I said it's 13 years old, at best halfway through it's expected life span. He then snapped at me "whatever, fine, 13 ok?". Don't add a magic 7 years to my boiler's age to justify your incompetence. All he would do is offer me another weekday appointment and make me miss work another day. I asked for a Saturday appointment now that I signed up for the membership that opens up Saturday appointments. He laughed mockingly when I mentioned it. Good to know the membership is worthless and a scam. I can't warn you enough. Stay away from this company. Whatever reputation they may have earned years ago has been squandered by whoever is running the company now. Very unhappy customer. read more

My 8 year old 3- zone split unit had stopped working. On the first visit August 5th the service rep said he found a leak and added 2 lbs of freon and that the thermistors needed replacing. Two years prior, I had to add 2 lbs of freon. He said that locating and fixing the leak could run in the thousands. $1100 just to look for the leak. That it could be as much as $3000 - $4000 and that the system I had was only good for 10 years (not true, 15 yrs). Considering how much it had cost to install the current system, I asked whether it made sense to do the repairs. That we were planning on adding a 2 zone for another area of the home but it may make more sense to replace the 3-zone with a 5-zone based on his assessment. This was my mistake as it seem the focus shifted from repair to replacing. He offered to have the company do an estimate which I receive 2 days later for $27,000. The cost of the 1st vist was $646.39 which was for the service visit $279 and the balance for the freon. The rep. assured me that I would not have to pay an additional service cost for the repair, just for the cost of the parts which would be around $300. A few days later the company called to set a date for a second visit to effect the repairs. During the call I was told I needed to pay an additional $655.94 which included labor cost. I told him that the rep said all I would pay was the cost of the parts. He said the rep was wrong and that was what it was going to be. This was in the middle of the heat wave here in NY so I had no choice. This left a bad taste in my mouth and I knew I would not want to do further business with the company. The rep was a middle age male who seem to have been with the company for a while so it was a stretch for me to believe he made a mistake. The repair was done on August 12 by another rep, however 2 weeks later the system stopped blowing cold air. On August 27th they sent a different rep to check. He said all the refrigerant had leaked out, that I would have to pay $900 to replace all 7 lbs and $1100 for them to search for the leak. Fixing the leak would entail an additional cost. I declined. I noticed that after he left the system was completely non-functional. Remember it was working before he looked at it just not blowing cold air. My husband who knows a little about HVAC systems was furious. He said there had to be something they did during the repair that caused all the freon to leak out in two weeks. He was finally able to convince them to send a rep to check. During the conversatiin the supervisor kept saying the system was old. TFO then made an appt. without conferring to see my availability. I called to let them know that I could not take another time off that week as I already did for them. Could they change to the Friday instead of the Thurday as it was a day off for me. They said no, that I would have to call back the following Tuesday after the labor day weekend. I decided to get another company and while searching reviews I came upon reviews on Yelp for TFO. They were HORRIBLE and reflected my experience with them. One submitted July 2024 by a customer living in a town 5 miles from me stood out. She had a leak in her split unit and was told she would have to pay $500 for them to search for the leak. Why was I quoted twice that amount less than a month later? Second experience with overcharging. Had to get a new company that was here yesterday to look at the system and found a significant hole in the pipe close to where they attach the machine to add the freon. Also one of the wires in that area was clearly cut. There was no rust or wear on both areas so it was recent. The serviceman said it is next to impossible for the third rep from TFO not to not have seen the hole. My husband was right about it being their actions leading to the leak. I did submit a report to the Better Business Bureau and the company response was rife with misrepresentations. They are a morally bereft company with discriminatory pricing practicies. Avoid at all cost. read more

Very unreliable company. I had paid for and scheduled a tune-up of my AC weeks in advance. I arraigned for time off from work because I could only get a 5 hour window for the appointment. A few days in advance they called and said they could not make it and re-scheduled. Took more time off from work and this time....they didn't show at all. Now fighting for my money back. Not worth the hassle. Plenty of other companies out there that may want and deserve the work. read more

Our central air had lived its life out. We contacted T.F. O'Brien, who we've been doing business with for probably 20 years. Tom O'Brien came over, and explained our options, and we opted for a new Carrier model. John and his crew of installers did a fantastic job of removing the old system, and installing the new system. They were professional and knowledgeable; very friendly and extremely neat. And, when they were all finished, John walked me through the entire job, and answered all of my questions. I couldn't be happier. read more

I have been a client of TF O'Brien for over 10 years. they installed my Ductless A,/C I have a contract with them for yearly maintenance. this year , I contacted them & was given an appointment 3 months later. they subsequently never contacted me to confirm the appointment. so the day before my scheduled appointment I contacted them & was told that the appointment was canceled. NO WAY TO TREAT A VALUED CUSTOMER !!!! read more

Made an appointment. I was told they would be here in a 4 hour window. Was not told that if I didn't answer the phone for an extra confirmation call the morning of my appointment, they just wouldn't show up and would never bother to let me know. Unbelievable. Do not use them. read more

Great work performed. I have been using The Company over ten years.They are reliable and dependable.

I am glad I chose TF O'Brien. Modern equipment, professional installation, combined with old-fashioned "customer-first" values. I couldn't be happier. read more

I work in a medical office . I called to request a service call due to our air conditioning not working. Even though it is mid october, due to the sterilizers and equipment that we use in our practice we use the air conditioning all year round. I explained this to the person I spoke to. I tried to explain that this was kind of an emergency due to our equipment and the comfort of our patients. They told me that they could not come until 2 weeks later. Mind you this was not in the height of the summer. Mean while they advertise emergency service. FALSE ADVERSTISING at its best. If you want fast and prompt service dont bother calling them. read more

Last year our central air system went down and were having horrible summer, we ended up calling lots of vendors to come give us quotes. We were pleasantly surprised when one of the owners Chris came himself to evaluate our issues and guiding us on what system we should replace it with. Hence we decided to go with them and we were glad we did. The installer and customer service were beyond friendly and Uber professional. Highly recommended. read more

RIPOFF ALERT! Called T.F.O'brien about water dripping to the floor from the relief valve on my Burnham gas boiler. They sent a tech "Nick" right away, but they never told me beforehand that there was a "diagnostic charge" aside from any repair charges. I found that out only when he was already here. Problem was only a broken expansion tank but tech installed a new expansion tank AND relief valve. Work took less than 2 hours, was charged $639.65 to install these parts that I only later found out cost only $65 from a well-known supply house plus the $79.50 diagnostic fee just for showing up and $195 for a yearly contract, with tax $993 total. I was told it would have been even more expensive without the contract. The problem was repaired OK but my inquiries reveal that I was taken advantage of and grossly overcharged by this company. Stay away. read more

Don't leave your scrap metal around TF O'Brien because they'll steal it and sell it! I have nothing else to say

6 years ago we needed a heater/ ac unit for our basement. Figure let's go with someone local. Had a ductless unit installed and 2 weeks ago the lights started blinking. Called TF O'Brien to have a tech come. Was told it's a $250 charge. The unit has a 7 year warranty - well ... $500 after the tech comes we are told the unit was covered but the labor to fix it was $2000. If we signed in for a service contract it would be $1600. Absurd!!! When We called someone else we were told that the Fujitsu unit we have is obsolete- stopped being made 7 years ago. So much for using the local guy. read more

I called them to get a price on regular maintenance and servicing on my units. They gave me an appointment for a couple of weeks later. The day they were supposed to be here (November 10) I got a call that they had to cancel but could come at the end of the month. No, thanks. Judging from their reviews there are issues with them anyway, and I don't need to deal with someone this unreliable if I do have a problem which needs addressing. read more

Recently had our hvac unit break down and requested a diagnostic visit with TF OBrien. A technician from this company came by a few days later and assessed/diagnosed the situation. He did not provide a quote before obtaining authorization to work on this unit. After completing the work, technician gave us a price of the work performed, as well as adding the diagnostic fee on top of the labor and cost of parts. Did not believe this was an appropriate way in conducting the job, where a company would not give us a quote/estimate of the price of the work prior to performing the job. read more

Had a bad leak from broken pipe in my basement.. flooded! It was a Sunday and I have a service contract with them. Tried to Give them the business due to being a family owned and operated neighborhood place. Tuneup last year.. perfect. Now there is an emergency. Tech shows up promptly, goes into his truck and says that he doesn't have the part... it's a standard domestic pipe!!! So now Im charged 160 for service call, nothing done and still have broken pipe. So pompous Casey O'Brien calls two days later and wants to know when I want to schedule to fix pipe... seriously? Like I was going to wait two days with no water. I tell him my complaint and he tells me that I can't expect the tech to have every part on the truck. So I said so he can just drive around on off hours with an empty truck and collect service fees all day? Just such a scam to pull on a customer in crisis. You think he would have better customer service and personality falling into the family business!! Now I see why the rating is so low. Too much competition out there!! So it's 160.00 lesson!! read more

They provided a quote more than double the other two professional quotes received. Totally exorbitant. You'd have to be crazy to go with them. Get other quotes, you'll thank me. read more

Working on my 6th week with no central air conditioning. In the beginning of June, the first technician arrived with an assessment of the problem and a solution. Next came the second technician with a different solution. Finally came the third. And then a part needed to be replaced. The fourth technician came to take a picture of the part that needed to be replaced (even though this company was the one that installed the new unit years ago). I assume now the part has been ordered, but maybe not received yet? I don't know because they really don't seem to care that during the most sweltering of days, I continue to live in a hime with no ac. Inside temperatures have reached 85 degrees. read more

Stay away. Overcharge on everything. Buyer beware. They didnt fix the problem and charged me for the return visit. Still shaking my head.

This is the 2 Nd time they let me down. After I called and left a message to service and repair my AC Split wall unit they called me back two days later to scheduled a repair for 2 weeks later telling me the have experienced in Split units and they always repair them , but they came today Ron the service man told us he is not going to waste his time repairing my unit , I should buy a new one from them .... I said its only 3 year old I paid $5000. But he didn't want to waist their time to repair , Ron wanted to sell us a new one , after they made me wait over two weeks for the service . This is the worst company. I don't recommend this stupid people who take Service calls just to sell you something. They are not capable of repairing nor reliable ! read more

Stay away from this company. Customer service representative is polite. Then it's all down hill on service and repair. The company fails to achieve a level of service they claim the they provide. We paid about $600 service contract, which includes seasonal tune up. Shortly after turn up, our hot water heater would not ignite. Technician repaired and charged us $167. Approx. two months later, same issue. A different technician arrived. He inadvertently commented that the first repair wasn't done correctly. However, I received another bill for $167. After I called customer service, I was advised not to pay. Months later, I kept receiving a bill. After calling again and receiving same direction not to pay, I received a collections notice (which I'm challenging). Too many headaches from a second rate company. Do not settle for TF O'Brien. There are plenty of superior companies out there. read more

Tom just departed from my house for a consultation on my inoperable boiler. Folks, I'd never talk bad about anyone but beware that this guy was very rude, emotionally callused, and pissed off against the world. He gave a quick 5 minute estimate and asked how much other companies were charging then told my wife to "have them fix it" and irately left my house. He was very unprofessional! BEWARE. read more

Service has deteriorated substantially. You can not rely on the time window they give More importantly you can not rely on the office that tells you they have two morning stops and they will then get to you. Of course they get to you at 6:15 in the evening. When you call at 4:15 and they tell you they are on their way and don't get to you till 6:15 you wonder where on Long Island they could come from? This is not the first time this occurred. Previously they called after the time window that they were on their way to do two (2) hour maintenance check. Too bad I have previously recommended them to friends and family. No mora read more

I was extremely happy with the work done during the service call for my natural gas boiler! Nick the tech was professional, kind, and explained the problem and solution. He took the time to show me a bit more about my system, fixed the issue with the heat, and even showed me how to set my thermostat for my radiant heat. I would highly recommend TFOBRIEN to anyone! Office staff and techs were second to none!!! read more

I would give them negative stars if I could. They are the absolute worst. Tremendous waste of time and money. I paid them $6500 to replace my furnace and they did not do anything right - they did not get a permit, wire the unit properly and they left the house with a deadly gas leak. I only learned of any of this when the inspector turned up out if the blue and gave me a whopping fine. I now have to spend another $6500 to fix their crappy work. Kerry is a liar and belittles his customers. It has been a nightmare from start to incomplete finish. AVOID read more

I had an awful experience with this company. I felt taken for granted because I had no idea about my AC unit and the company use that to there advantage. My unit was not working and I used this company 5yrs ago. You would think that they should go over the notes before going to do a job. The service person came in and quickly look at the unit and said I needed freon. I mention to him on there last visit it was mention to me there was a very small leak. He proceeded and fill my unit up with freon. Which cost a pretty penny$$$$ Two days later my unit wasn't working again and all the freon was gone. The company customer service was sub-par awful and didn't accommodate me in any way. They did suggest for me to buy a new "AC UNIT"of coarse $$$$$$ T.F. O'Brien work ethics are by far disgraceful and I would not recommend anyone to use them. read more

Friendly and efficient service. A little pricey but the heats is still on and working well !

Converted from oil to gas, and replaced the hot water heater at the same time. Went with TF O'Brien after getting four bids. The price was on the low side, if not the lowest. Brendan, the salesman, was very thorough in his explanation of what would be involved, and the bid covered everything, including removal of two oil tanks. Everything went as scheduled, from the crew's arrival through modifications of the installation and return to clean up some loose ends. The gas line was leaking a bit, but they were right back to fix it. Their response to questions has been quick and comprehensive. I wish I remembered everyone's names. There were several crews involved, but everybody involved was top-notch. And the house is toasty. read more

Our A/C unit in our MediSpa went down so I decided to try someone local. The last company I had shoved the wrong size filter in and told me that I would need a new compressor costing about $1500. Lenin showed up on time, within a day after I called, removed the old filter and replaced it with the proper one. He went up to the roof to check out the compressor and took a photo of the burned out part and replaced it the next day for a cost of $230 (service call and tax incl.). Lenin was prompt, courteous and honest. I would definitely recommend him and T.F. O Brien s to anyone. read more
