"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."

"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."

"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."

"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!"

"Installed new boiler and replaced all the plumbing in our basement (our house is 127 years old). They did a good job and worked hard to get our boiler replaced when the old one gave up the ghost in the winter. Also did a good job replacing all our plumbing in the basement and crawlspace in 2 working days. Kind of a strange name but don't worry, they are a really good plumbing and heating company and offer a 0% interest loan to pay for the bill."

"Apple Aire came on time and installed the new boiler and water heater and removed the old one with as little damage to the house and mess as possible. When my electricity went out the next day on the same circuit as the boiler, they sent an electrician who fixed the problem at no cost to me. I recommend them highly."

Install Boiler questions, answered by experts

Unless they are connected to the same system, boilers and water heaters will both need their own expansion tanks. The only case they wouldn’t have separate expansion tanks is if the boiler is pulling double duty and managing a heating system while also supplying hot water for a home. In which case, you may not need a hot water heater.

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.

The cost-efficiency of baseboard heaters depends on the type and how you use them. Generally, standard electric baseboard heaters can be expensive to run because they use electric resistance heating, which is less energy-efficient than systems like forced-air or heat pumps. However, hydronic and gas versions are typically much cheaper to operate. Hydronic models are more energy-efficient because they heat a liquid that retains warmth longer, preventing the thermostat from turning on and off as often. The overall running cost is also influenced by local electricity rates, your home's insulation, and your usage habits. To increase efficiency, you can use baseboard heaters for zoning, meaning you only heat the specific rooms you are using.

Overall, heating your home with an oil furnace tends to be less expensive than heating your home with an electric heating system. Oil heating systems stay warm for longer periods of time without drawing a constant electrical current to maintain a temperature. Plus, heating oil systems typically have a longer lifespan and lower price tag than their electrical counterparts, resulting in short- and long-term savings.

Using heating oil to heat your home has its advantages, but it also has its disadvantages. 

Consider these drawbacks before installing a heating oil system:

  • Heating oil prices fluctuate frequently

  • Risk of oil spills or leaks

  • Produces more air pollution and soot compared to a gas furnace

  • Regular maintenance required for equipment

  • Need to reorder heating oil consistently to avoid running out
