"Outstanding. Quality West owner, Rob and his assistant Junior, were professional and did outstanding work installing the Aprilaire Humidifier. They were thorough in testing it and delivering an excellent product. I will have them do all my HVAC work going forward."

"Pipeworx was hired to remove an old water heater and replace it with a tankless one in our summer cabin in Pagosa Springs CO. We were not there (in Arizona) so all communication was via phone, text and email.. Walt and Jodi kept us apprised of every step from product selection to installation. We arrived after the install was complete and met with them where they described every detail of the job. Communication is key to any long distance or local work and Pipeworx delivered in spades - the work was excellent and we are using them for another project."

"I called to get a third estimate on replacing my residential boiler. I was looking at replacing it because other contractors had advised that the cost of repairs was too high; repairing a 20 ye old boiler didn’t make economic sense. Gilles sent Justin over the next day, so very quick service. Justin gave me a ballpark price to replace it, which was more in line with what I thought was fair. He also gave me a very fair price to repair it — about a third of what the other contractors quoted. A good chunk money, but a much better option right now. Comparing what the three contractors told me, I’m confident that Justin had it all coveted. He then allowed me to video him, explaining what he did and what I should expect and look out for. He also sold me on their annual maintenance plan, which is a bargain because it includes evaporative cooler startup and shut down."

"Initially I requested an estimate for a plumbing project already in progress with some challenges. Keith responded immediately to get details and schedule to come out to look at what was needed. He proposed a solution that eliminated any impact to walls or tile to replace old valves and faucets. He and his team completed the work on time and were neat and professional and results were better than I expected. There was no damage at all to what was old tile. I subsequently had him assess an old water heater and decided to replace it. It had to go into a very small areas and be upgraded to code and he was able to solution the replacement to fit perfectly in the limited space. Previously on the project we had noticed a periodic odor of gas but no one had verified a source. Keith identified a leak in the area of the furnace right next to the water heater. We had decided to upgrade the furnace and AC and again Keith and his team were able to get an order in quickly, get the install done exactly as committed and fixed the gas leak in the process. Based on the quality of work performed in each case and the expertise of the team I hired Plumbing Tree again to assess an old furnace and AC at my primary residence. The furnace had been failing at the end of the winter but I waited for summer to replace and it had deteriorated and was not safe. Keith evaluated and gave me two options and was able to get the order in immediately after I decided to go ahead. He scheduled the install within a few days. His crew was on time and completed the install of furnace and AC in one day. Again they were neat, efficient, described all the changes from the old furnace and thermostat to the new and answered all my questions. Everything has been functioning just as I expected for both heat and AC. I recommend Plumbing Tree for these services based on quality and reliability - also cost was competitive and the team they used had the expertise required. Additionally they were easy to work with and I plan to use them again on another project. Thanks Keith and team- I appreciate the quality work!"

"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."

Install Boiler questions, answered by experts

Safety concerns with propane boilers include proper venting to prevent carbon monoxide buildup, secure gas line connections, and regular inspection of safety controls. Professional boiler installation and annual maintenance are essential to minimize risks. Having a carbon monoxide detector installed in your home is essential for early detection of any leaks or ventilation issues.

Costs depend on issue severity, parts needed, and labor rates.

If you want a new boiler that’s going to help lower your fuel bills, you should buy one that has a high energy-efficiency rating. For example, a boiler that is rated “A” uses at least 90% of the energy created by the boiler. And in order to enjoy the best performance, it’s important to have it installed properly by a highly-rated tech.

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.

A home radiator works by using radiation and convection to transfer heat throughout your home. Electric radiators use metal to conduct heat and warm the air, which then rises to warm the room. Steam and hot water radiators work with a boiler and piping system to pump thermal energy throughout the home. Hot water radiators use a boiler to heat the water before circulating it to the radiator, while steam heating radiator systems convert the heated water to steam before circulating it out. When the water or steam cools, it travels back to the boiler to be heated again.
