"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."

Just an overall great experience and I would recommend them."

"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!"

"I Had 5 different bids on my bathtub and shower projects, Jim Needham was the most professional company I dealt with. Pricing is a concern ,and he came up with an amount I could work with. I am looking forward to having them install my products and I like the fact they are an actual plumbing company!!"

"Tipping hat has talented employees that do safe, clean, and complete work! I highly recommend them! We are no longer cold in our house thanks to Mark J, and service pros Jeremy D and David B. Mark J. the supervisor on our furnace installation project was the first person we met from Tipping Hat. He is kind, understanding and respectful. He took time to thoroughly examine our complicated and difficult heating situation and was able to explain what needed to be done and why. All of our questions were promptly answered, he was always available for a phone call and put extra effort into creating a plan and setting up a team to get started on our project right away. Mark was considerate of our feelings, always reassuring us and promptly addressing all of our concerns. Jeremy D. Tipping Hat's Service Pro, provided extraordinary service during the installation of our new furnace! He is punctual, courteous, professional and knowledgeable. We were comfortable with him in our home, as he took great care installing our new thermostat and kindly showed us how to use it. Jeremy was very patient and took time to answer all of our questions. He went above and beyond to ensure that we received exactly what we needed AND he saw to it that the work was up to code and done properly! We are so appreciative of his compassionate understanding of our situation and his prompt completion of a large, heavy duty job that required hours of hard labor. Tipping Hat's Service Pro, David B. was able to complete work on the installation of our furnace in some really tight spaces. He had to deal with a tiny, dirt crawl space underneath the house and was able to re-attach ducts to the vents in our home. He was positive, pleasant and hard working. I feel confident referring others to Jeremy D, David B, and their Supervisor, Mark J."

"Highest recommendation for the Aether Mechanical team for our recent boiler replacement--every detail of the experience was managed professionally and expeditiously, and the entire project was completed in one day. Take a bow Nicholas, Ivan, John, and team--virtuoso performance and a first-rate result! Two days after Christmas we woke up to a cold house and a boiler that would not fire up. Aether Mechanical responded at once by phone and Nicholas arrived onsite from Boulder to our house in SE Denver within two hours. Initial assessment indicated a burnt-out igniter. Nicholas replaced that and discovered during fire-up testing that carbon monoxide levels were *way* above acceptable limits. After repeated tests, the unavoidable conclusion was a cracked firebox, necessitating replacement. We reviewed estimates at three price points, selected one, and Nicholas mobilized his team. During a holiday week, working around challenges with HVAC supply house business hours, the team completed the installation entirely the following day. In spite of an expensive but necessary replacement, this has been singularly the best contractor experience I have had in 25 years living in a mid-century modern house that is starting to require more frequent repairs."

Install Boiler questions, answered by experts

Installation costs range from $4,000 to $12,000, depending on unit size, efficiency rating, and labor.

Some high-quality steam boilers come with 10-year warranties, but a well-installed, properly maintained model can last at least 20 to 25 years. Learning how to clean a boiler, getting an annual professional service, and keeping up with maintenance and repairs on your heating system are all important for getting the most out of your model. 

A furnace is a big unit where gas, heating oil, or electricity heats the air. The warmed air is then pushed back out through ducts and vents. 

A boiler uses electricity, heating oil, or gas to heat water that is pushed into the room through a radiator. This is one of the oldest and most effective ways to heat a house, but radiators can also be unsightly and leave hot and cold spots in the room.

Heat pumps use a refrigerant to move heat from outside into the house and return it to the room through ducts and vents.

There are several types of home radiators, and the most common are steam heat radiators, electric radiators, and dual-fuel radiators. Steam heat radiators are connected to a boiler. Electric radiators can operate without being connected to anything else—they just need an electrical outlet. If you have a dual-fuel radiator, you’ll see a valve at the bottom of the system with a wire coming out of it and going into a wall. These are often your towel radiators in the bathroom. The type of radiator you have will impact how you turn it on.

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.
