"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."

"My dad is elderly and needed a new HVAC system. So I decided to find a person who could install a new HVAC system and we found Cody. Cody was very friendly, honest, and communicated very well. At one point he told us we could probably go another 3-5 years with the current system, but since my dad only has so many years left we told he to go ahead and install a whole new system in. He treated us like gold and even spent the time showing my Dad all the new features with the thermostat. I would highly recommend Cody for any repairs or HVAC needs you have."

"went above and beyond in explaining every question I had. even gave advice on how to even out the temperature in my home. The quote was fairly priced. They do the work themselves instead of quoting a price and then contracting the job out to someone else, like a lot of other companies do. I had 4 quotes in total to have a whole home humidifier installed. I was most impressed with Robbins because of the attention to detail, patience explaining things, and very fair pricing."

"☆☆☆☆☆ dream team COMPANY! I had most contact with Julian throughout the job, but his partner and Electrician were JUST AS NICE. They had cloths on my floors, as they were in and out of my crawl space. They even left to get a particular component, specific for my install. No damage to home. There was no laughing or joking around. They were concentrated on install, measuring, calculating out loud between the three of them. No cussing or profanity, either. Julian was professional and explained everything to me, including why manual was left on unit, so when inspector came, it was there, as it couldn't be signed off without it. Thermostat looks great! He also knew a lot about furnaces, which is my next thing. *Beware of companies won't give you prices on ANYTHING and/or charge you estimate to come to your house... Another reason I picked PEAK HOME was their receptionists! Sweetest, most understanding ladies! If you need to install A/C, go with this company - definitely recommend!"

"Nick our installer arrived on time and was very friendly and courteous. He worked fast and carted off the dead water heater and installed the new one. He showed us how to start the pilot light in case we needed to do it in the future. He made sure to take all the trash with him. I had called the day before to get an estimate and they were able to schedule us in right away. This company had the better price and warranty from the others I asked for prices. Abbey from the office was also very friendly and quick to send me a written estimate. There were no hidden fees and I paid exactly what they said it would be. Nick's friendliness and professionalism was icing on the cake."

Install Boiler FAQs, answered by experts

Boiler installations and replacements cost between $3,600 to $8,400. Expect to pay around $5,900 on average for a new boiler, including installation. Adding new radiators or heaters to the boiler may include separate costs if you are also upgrading those components, so the final price may be higher. To decrease costs, you can look for local energy rebates for using a boiler and wait until installers are offering discounts for a first-time installation.

Hydronic and standard electric baseboard heaters differ in how they operate, their cost, and their performance. Standard convection heaters use electric coils to heat the air directly, while hydronic heaters warm a contained liquid like water or oil, which then radiates heat into the room.

In terms of cost and efficiency, hydronic heaters usually have a higher upfront price but are more energy-efficient and cheaper to run over time. This is because the heated liquid retains warmth, allowing the heater to continue providing heat for a while after the thermostat turns it off. In contrast, electric heaters provide heat more quickly but are less efficient.

Ultimately, the better choice depends on your priorities. If you need a room to heat up fast and have a lower initial budget, an electric heater might be suitable. If long-term energy savings are more important and you don't mind a slower heat-up time, a hydronic heater is likely the better option.

DIY is not recommended due to safety risks and technical expertise required. Hire licensed professionals.

The absence of heating or hot water, unusual noises like banging or gurgling, and visible water leakage are key signs. Abnormal boiler pressure, flame irregularities (for gas boilers), or pilot light issues may also signal trouble. Frequent cycling, soot or staining, and unusual odors, particularly gas-like smells, should not be ignored. Modern boilers often display error codes or lockout mode upon detecting issues. Uneven heating across radiators and rising energy bills without increased usage can further point to problems. Prompt attention to these signs is essential to prevent further damage and ensure safety.

Scale from hard water is hard to diagnose until it starts causing problems. If your area has particularly hard water, that’s most likely what your boiler is using. If scale build-up becomes a problem, it starts to cause decreased flow and heating, and eventually, valve failures as valves become blocked. Let boiler professionals know if you’re worried about scale and they can offer advice or implement a solution.
