"Drew from Legacy Plumbing came out IMMEDIATELY to our rescue because not only were all toilets and showers unusable because water would flood downstairs but we had a birthday get-together with family happening within the hour. Drew was very knowledgeable and quickly fixed our clog and we needed a replacement part for an obvious leak. Legacy Plumbing is super honest, and you don't feel like you're getting ripped off with unnecessary b.s.. This is the second time we've called and because of the great job he did on our last major issue with our old pipes, we called him again. The cleanliness, effeciency, and honesty of this company is why I felt compelled to rave about them and let people know in a review. Definitely my plumber and business to recommend from here on out."

"
I had previously had another company cut roots from and scope the sewer line from the house to the main.
I was not home at the time of the work.
They reported that my line had severe breaks and needed to be replaced or relined. Cost would be over $10,000.
Of course, I wanted a second opinion on the condition of the line and need for repair.
Big Angelos came out - On Time and professional.
I told him why he was there and he allowed me to watch as he scoped the line and I could see for myself.
We watched as the camera clearly showed that the materials that the pipe was made from was not as described by the original plumber / con-man. Further, Big Angelo's showed me how the line was slightly damaged, but not anything that needed to be addressed for perhaps 10 years or more. Perhaps more importantly, the scope showed how the line was shared by my neighbor! If I had replaced or lined the pipe, I could have prevented my neighbor's sewage from draining.
He let the job be what it was. Meaning he was called to scope and assess the drain. That is what he did and he did it well. Explained  and answered concerns and questions and didn't exaggerate or try to upsell me into anything else.
I have since referred Big Angelo's to a property manager friend of mine and another home owner in Carmel. Both were very satisfied and keep Big Angelo's as their Go To Plumber.
I appreciate that they handle their business fairly / professionally. I wish more service companies were like this.

****See My updated review for Big Angelos. While this was a great experience, my most recent experience has me withdrawing support for the company and letting my friends know that unfortunately this is excellent experience is not representative of all their work. Too bad they couldn't continue to be fair.***

"Omar of Clima did a maintenance cleanout of the element for the air conditioner and replaced some (3) important parts. He loves his work it is obvious: his willingness to come back a second time to get the right model part installed and his eagerness to make right any complaint. I had found my intermittant problem was not fixed with the first visit, so Omar made it right by giving a free second visit the next day, including the part for free! I felt I was treated very well for a new customer. I more than encourage anyone considering Clima for their HVAC needs. I even am on first name basis with his front desk already."

Install Boiler FAQs, answered by experts

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.

The most important sign of a boiler problem is something happening unexpectedly, which is why regular boiler maintenance is important. Unexpected problems can include strange smells, new leaks, and unexpected noises that your boiler wasn’t making before. Additionally, if a boiler keeps shutting off or can’t maintain a specific temperature range, it’s time to call in an expert.

The radiators closest in proximity to the boiler heating system will heat up first. Radiators in rooms farther away from the boiler will take longer to heat up and may be the coolest rooms in the house. The radiator unit itself should heat up evenly; otherwise, there may be trapped air inside it.

Coolant and antifreeze are technically not the same thing. The difference between the two is the ratio of water to other chemicals. True antifreeze is mainly made up of either ethylene glycol or propylene glycol, while coolant comprises one part antifreeze and one part water. However, the terms coolant and antifreeze are often used interchangeably, even by pros.

Many HVAC companies offer free quotes and free estimates for repairs and new HVAC systems. Others offer low-cost quotes or apply the cost of the estimates or diagnostics to your final bill if you hire them. Be aware that some companies advertise free HVAC quotes and recoup the costs by charging more for their services. Free HVAC quotes are never truly free—they cost the company time and effort—so be a good customer. Also understand that you may end up paying for free quotes in another way if you don’t hire a reputable company.
