Get matched with top boiler installation pros in Derby, CO

"I'm very satisfied and please that we went with Behold HVAC for our install of our central A/C unit. We encountered nothing but professionalism from the sales rep, installers, electricians, plumber and who ever takes the calls at their office. Just an overall great experience and I would recommend them."

"We hired Plumbing Tree to fix an improperly installed flange by the builders of the home. The quote from them was a little high, but calling around it was similar to other plumbers. The plumber agreed that the flange was not installed correctly (rotated 90 degrees) and the bolts were stripped. The first appointment was missed, I got a text message an hour before he was supposed to show up saying that he could no longer make it due to the current job going long. The next day, I got a text right before our installation time window that he would be late. The plumbers were professional and seemed to be doing a good job. They were thorough and cleaned up after themselves well. The sink wasn't caulked as we want to touch up the paint first and he was very kind to actually leave us a tube of caulk and a rag for the job. After the job is done, there are two things that are bothering me. The first was that the flange (double flange to increase the height) was installed in the same 90 degree rotation as the initial one, so honestly I am a bit confused on this (the slots where you are supposed to put the bolts in every single manual on toilets are at the front and back instead of the side and the top and bottom slots were used on the sides instead). The toilet itself is slanted, not perpendicular from the wall (not by a huge amount, but it is noticeable). Since it is caulked down on our new floors, it is going to be permanently off square. Over all, I think they had a good attitude and the job that was quoted for 1 1/2 hours took 2 hours, so not bad there. We are saying we would not hire again due to the rotation of the flange, the inconvenience of rescheduling twice and that the toilet was installed a bit crooked."

"Outstanding family-run company. Efficient, professional, reliable, and friendly service. Jim personally handled my plumbing "emergency" on very short notice, and he absolutely exceeded all expectations. I had a saddle valve - connected to the water heater - fail, and he not only fixed the leak but installed a stronger valve/line to mitigate the risk of another premature failure. Jim Needham Plumbing is a top-tier company that goes above and beyond, and stands behind their work; this is the type of small business I am happy to support and recommend to friends and family."

"New boiler installation was completed in a professional and timely manner with great attention to the details. The system looks good and works beautifully!"

"They were very quick to provide an estimate and timely turn time on install. Everything was done on time and as promised. Highly recommend."

"Every step, from the estimate with the super friendly Ryan, to the final walk-thru with the always professional Gemini, was absolutely top notch. They installed a new furnace, A/C, and tankless water heater and we are very happy with the work and final outcome. The whole crew was wonderful!"

"New Era HVAC was amazing! I own a small business that has a very challenging environment to work around. Jared was extremely professional and minimized the disruption to our routine. We have large warehouse heaters. A few years ago we had one installed by another company. They left a huge mess, took 2 1/2 days to do the work and had no regard for disrupting our business. In contrast, when Jared replaced the second one he was done in one day, left the area clean and neat when he left, and was extremely accommodating with us. We have also had a tankless water heater replaced by New Era and had the same experience. Professional, honest, and reliable - you will not find a better company out there!!"

"Like any plumbing job today, the cost of installation is rough two or three times the cost of the item. This is a product of shortages of skilled help and there is little to be done. If you want it done particularly with any speed you will pay these prices. The cost of a water heater installed is three times what it was only ten years ago."

"These guys are above excellent! I already had estimates from 2 companies for for a new furnace. One was way too high, and I just didn't feel right about the second one. I called One Hour and got an appointment for a quote the following day. Habib came and took all the measurements for the entire project and gave me an exact price for the work. He explained everything I wanted to know, including the high standards their company follows, from getting exactly the right heating capacity to the requirements for every one of their employees: from drug screening and criminal records to excellent work and cleanup. They have a great guarantee, without any of the usual "membership" stuff that many other companies have. (I asked Habib about the lower estimate from the other company, and he showed me that it was only an estimate that could change. So even though it was lower, it could have ended up being much higher.) The next day, Greg and Ryan came and installed the furnace. Wow! They came and did the work quickly, quietly, and efficiently. They cleaned up afterwards. Greg showed me the new furnace and how to use the emergency shut-offs, and how to change the filter. And he explained how to use the thermostat. I appreciate working with companies that are excellent, and I've found one here! I highly recommend them for any heating/cooling needs."
