Triangle Heating, Cooling & Plumbing

I purchased a new Lenox heat pump in Nov 2024. It stopped working in July 2025. All parts were under a 10 year warranty. We were told by repair man that he had the part but we would either have to pay for it or possibly wait 2 weeks for them to submit the warranty information. They give horrible customer service. If they had the part in stock why would I have to pay with a 10 year all parts covered warranty. I would consider doing your business elsewhere. The manager was very rude with me and refused to submit a claim for me to get my money back.

I contacted Triangle and had an appointment for Friday. They couldn't give me a time so I took off work only to get a call that they weren't coming till Monday. I took odd Monday thinking someone was coming to fix my valve on my furnace. A guy shows up, takes some pictures, talks to a guy on the phone goes to his truck and gives me a quote to fix it for $3735.34. Total scam!!! They weren't even prepared to do the work that day. I don't know if they thought because I was a woman or what that I would pay that much. I think he thought I was stupid. Today I finally got it fixed and the total charge was $169.92. Thank you to Belleville heating and cooling!
Triangle is a rip off!!

Predators? Watch out for the ELDERLY!
Triangle arrived to look at a heating issue and gave false information about the problem and then tried to make me sign for a $1,500 estimate. Furnace only cost ~$3,000. My kids tell me to beware of scammers and predators that do this sort of thing and something smelled fishy, so I decided to decline the work and risk paying for another company to assess the repair. The new guy charged me only $150 dollars for the entire repair (a problem completely different than what Triangle quoted and more complicated to boot). My suspicion or guess is Triangle would have charged me the $1,500 for the false problem they fed me, then while working on that, they would have ""discovered"" another problem (the real problem) so they could charge another $1,500+ to fix. After $3,000+ invested, I guess they'd hope I'd be innocently pleased my heat was back on and I would join the cluster of good reviews? That's just a suspicion but I didn't just fall off the turnip truck. If you risk calling Triangle based on the positive reviews, then I offer my advance condolences and warn you not to sign ANYTHING and get another opinion before authorizing expensive work. You'll see for yourself that it was worth the second call!

Called me 3 months after work was done and told me I owed them money for a heating system project that took 2 months and three service trips for them to get it right. I know this bill was fully settled on the third visit, christmas eve, when I finally had heat after 2 months and begging. Did not provide receipts at the time of the work, could not/did not provide additional details requested when they tried to charge me more money. Threatened me and I wound up double paying for work. Their accounting practices are, at best, sloppy, and their customer service is terrible. Find another company.

Called them to fix a leaking bathtub spigot. A week later, they came, as scheduled. We have weird schedules, so scheduling service for anything is a nightmare, so we were excited to be able to schedule them.

The work couldn't be done that day, so we scheduled a time for them to come back, which was two days later, at 8am. On the scheduled workday, at 9:15, still no Triangle. Husband called to find out why, only to be told they had training that morning (they didn't know this on Tuesday??) and they couldn't come back out until the following week, despite my husband confirming the 8am appointment not once, but twice. And received confirmation back from Triangle.

Needless to say, its now been a week....and we only have that ONE bathroom. All this after having to take out a loan for the repair. We bought the $12 piece we needed at Home Depot and another company is putting it on for $75. Don't ever call these people. If I could give a negative star review, I would.

We were quoted an astronomically high price to replace our system. Something just felt off, not only about the price but the high-pressure, bullying sales tactics. The guy was pushing us to sign something right then when we hadn't even consulted other companies. The guy also resisted putting the quote in writing and that really set my alarm bells off. We told him we'd think about it and refused to sign anything. That day, I posted in a local Facebook group, not naming the company, just asking neighbors for ballpark figures of what they had paid for similar systems. The sales person then emailed my husband, saying he saw my Facebook post and that I shouldn't have asked my neighbors --- that email was super weird. Later we got follow-up calls that made us really uncomfortable. I am so glad I followed my instincts. A couple of people in my Facebook group messaged me privately and sure enough, they had had similar experiences.

Purchased HVAC system and had it installed January 2023. Had several service calls for it not working and smelling propane around tank and lines they installed. Finally got tired of not getting results and being way over charged and taken advantage of. The 60 months 0% financing is not worth it other local dealers can do a better job for less money and better service.... Don't be taken advantage of.

Really nice technicians will come to your house for a small problem and create a quote for thousands of dollars of repairs whether you need them or not. Definitely Get a second opinion because the number of complaints is increasing weekly. The local tradespeople all know about Triangle's poor reputation. They will use scare tactics to convince you of a worst case scenario (your house will burn down unless you use their services, your pipes will burst unless you contract plumbing replacement with them). It's unfortunate that they prey upon people's worst fears and massively overcharge for thousands of dollars. Like Maria's experience posted below, when I declined service after finding out there were all these complaints, they sent me nasty text messages. It's mind boggling that a company would behave so unprofessionally. And I cannot help but wonder whether they are posting their own google reviews because on this site, it's the same scam story whereas they have unnaturally high scores on other platforms.

We spent close to $70,0000 with Triangle. They installed a new roof, hvac system, plumbing and electrical. We had problems after problems from no shows to flooding our basement, new roof leaking, cracking our ceiling (refused to repair this...finally got them here to fix it and nobody shows up to finish the ceiling). They said we were abusive and hurt their employee's feelings. Wake up fellas!! When you don't show up when you say are and do a shoddy job, your feelings are going to get hurt. We are praying that everything Triangle installed will work in the future. They even tried to take away our warranties. Zach told us that he wanted to fix our ceiling his way We wanted it fixed correctly. He told us that he would take all of our warranties away if we made him fix it our way (which they ended up taking the entire ceiling down anyway...their way didn't work? Who does that? No reparable contractors that I know will tell you such nonsense. I am posting photos of the ceiling they have left us with. It took them 4 months to complete everything. We had a ceiling in the basement that was left (with their equipment still in our basement) for over a month. Lots of no shows and excuses for everything. DO NOT USE THIS Company!!!

I called for an estimate to replace my Central AC unit with a heat pump. As with any major purchase, I explained that I am looking to obtain at least three estimates. The Sales Manager, Heath, spoke at length with me and wanted me to make an immediate decision. I said I am ready to decide now. I explained I needed written estimates to compare and contrast the contractors prices and specifically the different models of heat pumps proposed. I had not heard from him for a week after calling his office a few times. Finally he calls and begins with demanding again for immediate decision WITHOUT A WRITTEN ESTIMATE FROM HIM. No price nor brand of unit. Then he accuses me that I would share the estimate with his competitors. He wanted to come back and look at the other estimates I had THEN make a proposal. The exact practice he accused me of just second ago! Dismissive, arrogant and combative, demanding that I just go forward with whatever system he has in his mind! No price, no model number of the heat pump! No wonder there are poor reviews of this company. Heath's aggressive sales techniques are alarming at best and most definitely offensive. He hung up stating that he would not deal with me at all with a written estimate, that I MUST just agree with his verbal plan, one with no price nor model of equipment. Heath's hubris and arrogance was breathtaking astounding. No wonder this company has low rating!!
