I would give zero stars if I could. I have a rental house, and the tenant called on a cold and…read moresnowy Friday evening to let me know that the furnace was not working, blowing cold air. It was after hours, of course. I called TNT and they promised me they could take care of it. They quoted me a super expensive after-hours service charge, but I was desperate and agreed. An hour later, they canceled, saying the best they could do was Monday. Now it is WAY late, and I have a tenant that is freezing, the pipes might also freeze in the house, and I am stuck scrambling around trying to find someone to do a late emergency repair. Their only suggestion was to call another company that has a reputation for being horrible. This used to be a reputable company, but now they have new management that is part of another big "group". Stay far away from this company.

I hired them to install a Corro-Protec brand powered anode rod in my water heater, and they did a…read moregood job. It is hard to find anyone who is willing to do this work; no one seems to be familiar with the powered anode rods. I was referred to them by Yelp Projects. They responded almost immediately to my Yelp request, and were able to come out the next day. Their communication is excellent; I got numerous messages confirming my appointment and letting me know the technician was on the way, as well as a follow-up call to check that everything was satisfactory. My only gripe (for which I knocked off a star) is that they are very expensive, even as plumbers go. They charged $857 for a 1-1/4 hour job, for which I provided the materials. One nice feature, though, is that they do flat-rate pricing based on the job and not on time, so you know in advance how much it is going to cost.

Mark showed up on-time and was very personable and professional. I know it seems trivial, but a clean pressed uniform, eye contact and a firm handshake mean something to me. He explained the plan before starting. He showed me before & after photos when he was done and made recommendations for future work without trying to upsell the call. I really appreciate that! I ended up signing up for the Maintenance Plan which has them come back twice a year because this is the type of company I want to do business with. Would definitely recommend True!

Last week we had one of our units ice up and True sent out one of their technicians to see what was going on. Matt spent several hours and had to leave and pick up a part to repair our unit. He got the job done the same day in temperatures in the high 90s ! To our surprise when the bill comes, there was no charge! True did not even charge us for the service call! Our 2 units where just past the warranty and True stood by their product. True Heating and Cooling is top notch and I highly recommend them.

Everyone I've interacted with at Front Range Water Heater has been great to work with and their…read morecommunication is excellent. Responses by email and text are quick and they answer the phone or call back promptly. Highly recommend for plumbing and water heater service! I started off having them do some plumbing work for me to correct issues identified during a water meter replacement. They did a great job so I quoted for some more work - a leaky toilet valve, replacing the main water shutoff gate valve that leaks by, and a spigot that cannot decide whether it leaks or no. They sent thorough quotes that gave me all the necessary information to gather comps (none of which were comparable in price or thoroughness). I decided to move forward with the water heater and leaky toilet valve (when it rains it pours; AC went out at the same time I needed this job) and Tim showed up right at 9. He was polite and respectful and got right to work. He brought the new water heater in on a dolly, appropriately strapped and used a part of the cardboard box to protect the unit from the ratchet strap. When he had to run out for a part, he let me know and went to get it. The water heater install and toilet valve replacement took around 3 hours. I did a goof and moved cash to the wrong bank account and didn't have my checking account funded on the day of service. I called and talked to Audrey while Tim was still on site and she said it was totally fine to write a check that would be ready to cash on Friday (it's a Wednesday currently). Customer service is top notch and a great example of why to keep using independently owned businesses when private equity and corporate options seem like an easier option. One consideration is that of the 4-5 times Front Range Water Heater employees have been at my house, none have covered their shoes. For service professionals entering a home in all weather conditions and going back and forth to the nasty crawl space, that's a level of respect to the homeowner that I hope for every time and rarely encounter these days. So I'm not docking them for it but I do hope they consider the practice.

It took them an entire summer to diagnose and…read morerepair the compressor I had bought from them and they had installed on one of my refrigerated beer tap trailers. This cost my small business $8,000 in parts and repairs plus several customer refunds. They took zero responsibility for the problems I experienced. When I questioned one of the owners about their continued misdiagnosis, I was treated very rudely and he fired me as a customer. He even threatened legal action if I didn't pay the full amount by the end of the week. All this after having worked with them for 3 years. Extremely high labor rates and over-inflated part pricing markups (I checked), and lots of nitpick charges. They even charge a $75 shipping fee for parts they have in inventory in their own warehouse, which is in the same small building as the shop and office. When I asked about that charge I was told "Well, we had to pay to have the part shipped here when we bought it." What? The people who work in the office and one of the field techs were nice and often helpful, but that is the only good thing I can think of to say. The owners of DNI Heating do not give a crap about their customer. You will be nothing more than a transaction to them.
