"The provider came and unclogged the toilet but left me with a toilet that would not stop running. After contacting the provider to let them know they texted me a YouTube video. They said that they were going to come back to complete the repair but did not. I ended up having to hire another company to complete the job."

"Dreadful experience. We had been customers of Astacio since 2015 when they installed our first tankless boiler which failed completely after 7 years and needed to be replaced in late 2022. ($10,000+) Their second one just stopped working; a dodgy board? The part is under warranty but they want almost $1,000 to replace it in the boiler; probably less than 2 hours work. I thought they used to be a good local business with ties to the community but be careful; their tankless boilers are unreliable and they'll try to rip you off when your heat goes out in the winter. So much for standing by their work. I'll never use them again."

Install Boiler questions, answered by experts

Common problems include leaks, low pressure, and inefficient heating. Regular maintenance prevents many issues.

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. 

A common HVAC rule is that for every 500 to 600 square feet of living space, you need 1 ton of heating or cooling capacity. Now that you know this common rule, you also need to know that it isn’t very accurate, and a dedicated pro wouldn’t use it for your home. If you talk to a pro who won’t or can’t perform a proper Manual J calculation, consider hiring someone more thorough.

A heat pump is more efficient than a boiler system, making it a popular choice for many homeowners across the country. Still, the boiler reigns supreme, with 8 million in the United States alone. Many people favor boilers despite their lower efficiency because they carry a lower price tag and less intensive installation. It all depends on your home’s infrastructure, your personal heating priorities, and your budget.

All modern boilers are condensing boilers because they’re the most efficient type. Instead of extra heat leaving through the flue, these boilers trap the heat and use it to heat the house. Whether you choose a combi boiler, system boiler, or regular boiler, you can opt to get a condensing system. If you have an old boiler that’s not a condensing boiler, it’s a good idea to get an upgrade.
