"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."

"Great Job--highly recommended. They installed a gas line extension for my new kitchen range. When I asked for an estimate, they showed up on-time and walked me through the various aspects of my job. Bid was less than competitors and was based on the work to be done and not some set rate for "the standard kitchen range extension job" like other companies. For the job itself, they got in, quickly got to work, adapted the game plan when things turned out a little different than initial expectations, and completed the job on time with a high level of craftsmanship. I could not be happier with the result!"

"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."

"Keith was excellent from his first visit to explain what needed to be done on the kitchen drain. Afterwards, I requested a new water heater to be installed. Both were done this morning in a timely manner. Keith is very competent, takes the time to explain everything, and did an excellent job. I also was extremely thankful to Keith this morning as he identified a gas leak that I otherwise would not have known about. Because of Keith I was able to call the gas company and they came out within the hour to address the problem. I highly recommend Keith to anyone needing services. And, if I have any future issues, Keith will be the first person that I will call. He is a wonderful person, and he did an excellent job for me! Thank you Keith!!!"

"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."

"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."

"Mitch is great. Very thorough. He came to certify my system and had to be really honest. He showed me the damage and offered a fair price for the furnace replacement. He was done in a day and it looks amazing."

"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!"

Install Boiler questions, answered by experts

The primary differences between a heat pump and a boiler are their function and how they produce heat. A heat pump is a versatile system that provides both heating and cooling by moving ambient air and altering its temperature. In contrast, a boiler is solely a heating system, often working with a furnace or AC unit as part of a larger HVAC system. In terms of heat production, a heat pump generates heat more slowly and at a lower temperature, requiring a large convector for distribution. A boiler, however, produces a large amount of high-temperature heat that it emits through smaller radiators.

Yes. In many cases, switching from an old furnace to a high-efficiency boiler can help you save money over time. You can also save money by switching from an electric boiler to a gas boiler, which costs much less compared to the energy bills an electric boil can create. Boilers are often (but not always) more efficient than furnaces, too. Then there are discounts, rebates, and incentives that can help you save on the initial costs.

Since your boiler keeps you warm and provides hot water to your home, you’re likely to notice issues with heating in your living space right away. The most obvious sign that your boiler is breaking is not getting any heat or hot water. You might also hear some odd sounds coming from your boiler during operation, the flame in your gas boiler is not blue, the pressure is inconsistent, or your boiler is using more energy than it should. If you notice any of these signs, be sure to call a pro right away.

Warmed or cooled air can escape your home through drafty windows and doors. If you notice any gaps, be sure to caulk and seal them. You can also hire a local pro for an energy audit to get a list of energy-saving recommendations. 

Finally, check your insulation. It can settle in over time and become less effective. The Environmental Protection Agency (EPA) estimates that you can save an average of 15% on heating and cooling costs (or 11% of total energy costs) by sealing leaks and making sure attics, crawl spaces, and basements have a nice layer of insulation.

When winter rolls around, and you turn the heat on for the first time in a year, it’s normal to sense a light odor. This could smell a little like burning because some dust has gathered in the heating unit over the warm months and will fade away shortly after. However, there are some smells you should watch out for and take caution around: an egg-like sulfur smell or an electrical burn odor would indicate there’s something wrong. Turn it off and call a professional for maintenance as soon as possible.
