"Before, we only had a localized very old gas floor furnace. Total Home Environmental installed a centralized Heating/AC system in the attic and insulated the attic as well. They installed vents and ducts (first time for the house). They did a good job."

"We had 2 jobs done by Iwai. First, they did the central air for our 3 bedroom house in LA. Many of the other companies said we needed to put in additional vents but Iwai suggested putting the system in and adding the vents later if we were not satisfied with the air flow. This ended up saving us thousands. the second jod was a mini-split HVAC for our garage conversion. our general contractor gave us a ridiculous price so we called our friends at Iwai for a second opinion and they were great. The price was low and when the inspector gave us a hard time about silly details Brandon sent his team out multiple times to deal with it even though it was a relatively small job for them. Both times the work was high quality, the price was great and the professionalism was above reproach. I would recommend them without hesitation to anyone."

"The technician was prompt, efficient and very through. He cleaned the vent from the interior and exterior and re installed the dyer without mishap . Air flow through the vent is much improved  and the dryer is much more effecient as a result. A great service at reasonable fee. I'd use Breezeway again for similar services."

Install Boiler questions, answered by experts

The average lifespan of a boiler is typically between 15 and 20 years, though some may last for as little as 10 years while others can reach 30. A boiler's longevity is influenced by several factors, including the quality of the unit, proper installation, and consistent professional maintenance.

The material also plays a significant role. Older boilers made from durable cast iron can last for over 20 years, with some functioning for up to 50 years. However, it's important to consider their lower efficiency, which can lead to higher utility bills. Modern boilers, often made from steel alloys, are designed to withstand high pressure and temperatures and have an average lifespan of about 20 years.

To maximize your boiler's lifespan, ensure it is installed correctly, have it professionally maintained each year, and address any necessary repairs immediately.

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.

It can take anywhere from four hours to three days to replace a boiler with a new one. How long your particular boiler installation takes will depend on whether you need a gas line installed and if you’re switching to a new boiler system. 

Replacing a combination boiler or standard boiler with the same system should only take four to six hours. Meanwhile, switching from a conventional boiler system to a combination boiler system could take a few days.

If your boiler is 20 years old, it’s time to get a new one. Although it may seem to be working fine, it’s likely eating up more fuel than it should. Also, compared to a brand-new boiler, one that’s 20 years old is probably not working as well. When you get your new unit, you’ll notice that your home is heating more quickly, and the heat is consistent throughout all the rooms.

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.
