Terry Allen installed my tankless water heater app. 3 years ago, it was a satisfactory job. The heater went out this week and Jennifer, Walt and our service tech Dennis worked fast to get us fixed as quickly as possible. I can't say enough about Terry Allen's service. read more

We called for service. All we needed was a thermostat replaced. It was a very simple thermostat to be replace with the same. When we asked what the cost to do that and a cleaning/tune up on furnace, we were quoted $349. We declined and asked for them just to replace the thermostat. You can imagine how surprised we were to get a $321 bill for a thermostat and furnace filter replacement. For $28 more dollars, they would have cleaned and did a tune up??? Of course, we had to be charged up front and had to ask for the invoice because it wasnt provided up front. We were in a pinch and they knew it and took advantage. Consumer Beware. There are much more affordable and honest options out there. read more

They failed to keep their web page up to date and I went expecting a show room that apparent closed in 2020. A total waste of my time. They lost me as a customer. read more

Awesome service, honest work! Recommended by a friend who has used them for years. Couldn't be more pleased! Easy to make appointment, sent me reminders, and photo of Dennis B who came out and did an awesome job at very fair price! Told me what needed repair now and what could wait! They are my new plumbing & heating guys! read more

My furnace died and I scheduled with them for repair the next day. Dennis arrived an hour early (after calling) and had the furnace up and running in less than an hour. The price was fair. read more

04-19-2022 Drove out of my way to Terry Allen Plumbing Heating. Arrived to find sign - parts Dept CLOSED to public. Had to call to make an appt just to check if parts available??? We WENT to another business who was OPEN to public and had parts in stock. Terry Allen LOST a sale AND lost all future business. The pandemic us over. Our company HAS been OPEN all during pandemic and operating as normal.we NEEDED parts to stay open. Terry Allen FAILED to be open, FAILED to help, FAILED to be a business Our company WILL be shopping elsewhere and doing ALL business elsewhere from now on. read more

Never using Terry Allen again. I've used Terry Allen for various home improvement/repairs in the past, probably more often than I should have. I've used them on several occasions, for everything from repairing appliances and capping a gas line to the stove to bathroom plumbing. For the most part, the work that Terry Allen techs have done around our home has been "middling" and also very expensive, but usually they were professional when they came in the house and were able to do the repairs without taking up too much of our day while doing their thing and not making a mess, either. Seriously, until the last two calls to them, both the techs that came out to the home and the staff that answered the phones were always professional and courteous, but somewhere that changed and now so has my opinion of Terry Allen and I must say that this is not a change for the better. We needed a tech sent out to our house on a call for a broken water heater and we were told repeatedly (as in at least 8 times and always after I had to continue to call them back) that the tech was on the way. This was an emergency and we had scheduled an appointment the day before with the office staff, who stated that the tech would be out within the approved appointment window, which had a leeway of about two hours. I get it, they often show up at the later end of the appointment window, sometimes early, but they are nonetheless required to show during the appointment window and if something were to come up, a phone call from the tech or the office staff is necessary. We were told repeatedly that he was on his way. The appointment window came and went when we were already told at the beginning of the appointment window that he was "around the corner." Hmm. I don't think he was around the corner. I don't know where on earth he was or what he was doing. We had to schedule to be off work and at home for this, we were waiting and we had no hot water. After repeated calls to the office and several hours later, long past the expiration of the appointment window, the individual on the phone, who never once called me or asked the tech to call (common courtesy and common sense would tell you to do so, however, not in this case) gave me the last excuse of too many to recall and just yelled at me that the tech must've decided to go eat lunch or something! Where did this person answering the phone/scheduling appointments learn phone etiquette, anyway? Geez. I truly believe they needed a refresher course on how to answer phones because the behavior on their end was appalling. Seriously? Obviously, this was one of a rotating series of excuses given to us about the tech's whereabouts and we'd had it up to here by now. Oh, don't forget- he was supposedly "around the corner and almost to the house" for hours! I told the individual on the phone what an inconvenience it was and that this was highly unprofessional. The employee gave no excuses, only snapping, "what do you want me to do about it?" Again, seriously? I mentioned that we had used, up until this point, Terry Allen almost exclusively for plumbing/installation repairs for years, which they also knew about because it was in their computer records. The lady answering the phone simply acknowledged it. That was it. After the last experience we had with them, with an overpriced repair that should have cost much less than their estimate, we should have stopped using them, however, we gave them another chance and for what- to pull a no-show? Fed up, we told her to cancel the appointment and I contacted another plumbing company, who managed to get someone out to our house within maybe 20 minutes of the call. Go figure. I guess this guy was somewhere "around the corner" on another call or something, unlike someone else, so it was easy for him to get to our house quickly. While the other plumber's estimate was also expensive (realistically, none of them are "reasonably priced"), he was courteous, on time and very honest, which is more than I can say about Terry Allen. read more

My pipes froze and was in need of emergency assistance. They told me that they weren't accepting new clients.. what does that mean? I'm a paying customer!? If I could give these guys a zero star I would. read more

Great service, professional and proficient. Fair pricing with diagnostic put towards repair if approved. read more

It took them 2.5 weeks to install a toilet I prepaid for. They left me without a toilet for all that time. Because of the late installation (after removing my toilet the first day), I was told they would give me a partial refund. Terry Allen owner offered half back, I said less was fine. It didn't matter anyway as they didn't follow through with what they said. read more

Just spent several hrs with Joe from Terry Allen Plumbing and Heating. Furnace had unusual issues and Joe worked on it until it was running like new. Very pleasant and respectful man. Kept his mask on the whole time he was here. I have covid anxiety so having a repair man in my house was very stressful, but Joe was so nice and kind that I made it through the day with little anxiety. Highly recommend Terry Allen for your heating and plumbing problems. read more

I had 3 services performed over 2 dates of service and paid in full on each service at the end of the appointment. But just received a bill in the mail for over $1600, including 5 "finance charges" of over $20 each. Very poor billing practices. I will never risk my money with them again. read more

They did a very good job, the Installers took there time and did there company proud. Professional work. I was not called but was told they would be at my house between 830am and 9 they where here on time, it was a rainy mouring but the outside installer went above and beyond with his work, the other who worked on the coil and sheet metal Inside did a fantastic job as well..I would highly recommend them read more

I have used Terry Allen several times in the past for heating and cooling services. Never had a problem. Recently used them for plumbing services and was extremely disappointed. I was charged $430 to have my kitchen faucet replaced for a leak. The technician indicated several things were being replaced under the sink but after the job was done I asked him what was replaced. It turns out it was just the faucet. The invoice that was emailed to me did not include a breakdown of the charges. When I called to ask for a breakdown of the charges I was told they don't do that. So I asked for a confirmation of the charge for the faucet. Was told it was $193. I sent two emails so far asking for a confirmation that I was charged $237 for 1 hour of labor. They have ignored both requests. Terry Allen has proven to me they are not willing to clarify or justify their charges. I guess even they know I was overcharged or they would have no problem responding. It's a shame because I have been a good customer and always recommended them to friends. Not any more. My business is now going to Blessing Company Plumbing and Heating in Grand Blanc. read more

I had CO2 emissions coming from my furnace. I made an appointment for a repair/diagnostic. I paid $75 to hear a sales pitch. The "repairman" didn't bring any tools, no CO2 detector, or even a flashlight. The "repairman" poked around my furnace with a cell phone light and a bic pen for a few minutes, then told me that I needed a $1500 furnace. Total ripoff. read more

Not happy with you guys. When I called and told you guys I would pay the $69 for an estimate for the work for my father who lives out of state. But I wanted a call before any work was done with what the total cost of repairs would be. The repair technician took it upon him self to do the work without my approval. When I asked him about it he even said it ways his fault that he did that. I've never heard of a company proceeding with a work order without authorization that it was ok to proceed. I'm extremely disappointed with the service from you company. I would of authorized the repairs but would of appreciated a phone call letting me the amount before hand. I will never do business with your company again nor recommend your services to anyone. I do want to mention the quality of work based on what my father said was excellent, I'm just really upset the work was preformed without my authorization since I communicated to your company that I was the one that was paying the bill and never gave the go ahead to fix the ac without letting me know the cost first. read more

I have been using Terry Allen since 1985. They are always reliable and helpful. Saturday I just had an issue with a leaking kitchen sink, and they were able to resolve the problem very quickly. Thank you so much. read more

Knew I had to pay $115.00 for after hour service call but not the additional $177.90 for 15 minutes of work (sodering/adding a 4 -5 inch elbow). At that rate their hourly rate would be $711.60!!! After my comlaint to them Walt credited $88.95 which was half of the 15 minute rate which would still make the hourly rate $355.80. I am female and another female friend of mine hired them saying they were pricy and sorry she hired them. Of course, I will never hire them again nor will I recommend them. read more

I would give 10 Stars if I could!! The customer service rep that answered the call was very polite and understanding. They called when they said they would, the serviceman arrived when they said he would which is amazing in itself. The serviceman, James was very informative and very polite and walked me through the entire troubleshooting process. James repaired everything and then cleaned up after he was done. Once again I would highly recommend Terry Allen! read more

We have had Terry Allen replace all our plumbing, install two toliets, a bathtub, water heater and most recently a furnace and central air. We are very pleased with their service. Everyone who has been to our house has been very professional. They have been in our crawl space too many times to count and we have never heard a complaint or bad word from any of them. A lot of people say they are too pricey, well I say you get what you pay for. Dennis and Sally, Burton read more

Had them quote a Lennox inducer motor and they came back w $395.00 for the part only. I called around to find everyone else that is an authorized Lennox Dealer quoted between $189-$250-part only. They are virtually double! Stay clear! read more

My husband called and had them come out to install a faucet and disposal that I purchased prior. $500.00 for the installation for 2 hours of work. NEVER again. Would not recommend and they will NOT give you and any type of estimate before coming out. Do NOT use. read more

This company will never get any business from me ever again. I hired the company to do plumbing in my house and the guy they sent was rude and disrespectful. The job was time consuming and I explained the problem before they came to the house, they guy got mad and told us he wasted a whole work day because of my house , but that's what I paid for. The guy name was Dennis, he was here maybe 3 hours and complained the whole time and made us feel like we was inconveniencing him. Spoke to the owner only to be told he would talk to him, really hope he does no one should hire a company and get treated the way he treated us. You hire a company to do the job right but also to do the job in a professional, and respectful manner. I was uncomfortable while he was here that's how rude he was I read a lot of the reviews and I should have listened, I would have chosen another company. But through the terrible experience.... Lesson is learned never again will I every use Terry Allen on Fenton Rd. read more

5 of 5 stars I called & set up appointment they came out next day installed a Lennox furnace & air conditioner also a water heater . The crew worked over 12 hours got heat & water back on technician Mike was very helpful & polite he came back finished up the job . read more

I'd rate this company 0 stars if I could. If you're thinking of hiring them RUN THE OTHER WAY!! Background - in Jan 2008 my furnace was failing & I got quotes to replace it. Terry Allen's quote was in the middle of the 4 I received and at the time I thought it was a reputable company. On Jan 30, 2008 they came to install my new furnace. On Jan 31st installation was complete but the furnace didn't work and there began a series of useless "fixes" that would last weeks. Repairman came to my house on Feb 7th, 9th, 10th, 12th, 13th & 14th. It had now been 2 weeks & I was still in the cold!! I asked the workmen if, perhaps, the furnace they installed was to small for the space but was assured that wasn't the case. I was told it was "cycling to fast" among other excuses. They sent an engineer out on Feb 15th to evaluate the situation & he said the furnace needed to be re-piped. Repairmen came to do that on Feb 18th & 20th but it didn't help. On Feb 26th I was told there was a blocked valve, then on Feb 28th I was told the problem was due to "insufficient radiator length throughout my house". What BS!!! The sales rep inspected & measured my existing system when he made the quote and there had been no problem with the "radiator length" for my previous furnace. Terry Allen was getting desperate to find new excuses for their incompetence and I was freezing every night! I'm convinced that the problem was that they installed an undersized furnace that couldn't handle my house & they wouldn't admit it because it would mean starting over. Finally on March 1st - one MONTH after the first installation date - they said the only way my house would ever heat up to a living temperature would be for them to install 2 fan coil heaters that would cost an additional $1,102. They refused to cover the cost (although they did give me a discount) because they were blaming my "insufficient radiator length" for all the problems & ignoring all the other "explanations" I'd been given along the way! It was blackmail! They knew it was freezing out, that I'd already invested a month of my time working with them to solve the problem and that my only choices were to start over with another company or let them install the fans! I caved in & on April 9th they installed the fans, my house was warm again & I hoped never to have to deal with Terry Allen ever again!! Fast forward to present time - one of the 2 fan coil heaters started making an awful noise. On Oct 30, 2015 a technician came out, adjusted it (which stopped the noise) & said it may need a new blade in the near future. He was right, the noise came back and on Feb 10, 2016 the same technician came out & replaced the fan blade. He said then that if the noise came back I'd probably need to replace the motor. It stayed quiet until last week. On Nov 23rd I called & spoke to the receptionist. I gave her all the details - the name of the previous technician, what he did, what he said, the model & serial numbers of the fan - everything she could have needed to make sure the technician was prepared to make the repair. The first appointment I could make was for today (Nov 30th) & when he arrived the technician confirmed the problem. "The motor is frozen up & needs to be replaced BUT the manufacturer no longer makes that motor & I was only given your job this morning so I'm still waiting on a quote for a replacement motor". WTF - I provided all the necessary information a week ago! There should have been plenty of time to get a quote, get the part & be ready to do the repair on the day scheduled!! Now I have to rework my schedule to set another appointment whenever the motor happens to arrive. When I called to complain the manager I talked to basically said "that's just not how Terry Allen works. We can't just order a part until the technician confirms what's needed." Well obviously the technician did know what was needed, based on the research he did before he arrived at my house, he just didn't have time to get all the information, let alone order a new motor, because he was only given the information on the day of my appointment. What was happening for the rest of the week?? All I got from the manager was "sorry for your inconvenience" but he took no responsibility for what happened just as the managers 8 yrs ago took no responsibility for the fiasco that was the installation of my furnace. NEVER use this company, you will regret it!!! read more

Recently, after a heavy downpour our sump pump died. The backup pump was gushing water that was pouring next to the wall outside the house. It had been installed incorrectly by the builder. It should have been tied into the tile system that flows away from the house. Instead, the water was building up pressure against the house, putting the integrity of the wall at risk. Chris, from Terry Allen came that Thursday late at night. He fixed the way the water flowed outside so that it was connected properly, and replaced the auxiliary pump. He didn't have a main sump pump in his van, and it would be a hefty additional cost to get one that night. And, because we had an appointment early the next morning, Chris offered to came very early in the morning to replace the main pump so that we would not miss our appointment. He went out of his way to be accommodating. The job that he did was top notch, and he was very professional and knowledgeable. He replaced the pumps with better quality pumps and made sure that they were set up properly and that the connections outside the house were done right. Would not hesitate to call on Terry Allen again in the future. read more
