"The biggest obstacle was scheduling.  The Angie's List confirmation email did not include the instruction to schedule on the Flow-Rite web site.  It took 3 or 4 emails to clarify that which delayed getting the work scheduled. 
The replacement parts worked fine with the exception of some excess plastic on the valve which prevented a tight seal and thus lead to a running toilet.  It took a few minutes with the razor blade to cut the excess off and allowed the seal to form properly.  This probably should have been done by the installer.

"Last winter our old furnace wasn't working properly. Called Hauser and they came to our house within 2 hrs as furnce not working and very cold. Heat exchanger bad in an old furnace. Got quotes on 3 different furnaces that night and it was installed the very next morning! Since installation their service has been 5 star. Highly recommend Hauser Heating & Air."

"These guys were amazing. They were the first ones to call after I submitted a request on Angie's List, and they came out the same afternoon. They did everything they could to keep the price of the repair down, including calling the furnace manufacturer to see if some of the parts were covered by warranty. Then they were willing to work with me when it ended up costing a bit more than I expected (something that was out of their control.) They lent me a few heaters to put in my kids' rooms overnight since the parts place had closed for the day by the time they knew what they needed. The level of care I received from this company was incredible - not something I expected at all. I'm really happy to have worked with them, and I most definitely will be giving them my business in the future!"

Install Boiler FAQs, answered by experts

If you want a new boiler that’s going to help lower your fuel bills, you should buy one that has a high energy-efficiency rating. For example, a boiler that is rated “A” uses at least 90% of the energy created by the boiler. And in order to enjoy the best performance, it’s important to have it installed properly by a highly-rated tech.

If you have a closed-system boiler that requires an expansion tank, you cannot safely operate it without one, as this risks extensive damage or even explosions. You must find a way to make room for the installation. Options include repositioning the boiler, rerouting the boiler piping to a more open area, or performing minor remodeling to create the necessary space. If you are unsure whether your boiler needs an expansion tank or how to best accommodate one, it's recommended to have a local heating service professional assess the situation. They can confirm the requirement and suggest the most practical solution.

On average, you’ll need about two gallons of oil per day to heat your house when it’s 50 degrees Fahrenheit outside. Most oil tank capacity is about 275 gallons, and heating your house with two gallons of oil per day will last about four and a half months. This consumption will vary depending on the climate and average temperature in your location. For example, if the winters are longer and colder where you live, you’ll probably need to refill your oil tank at least once to get through the winter.

The average cost to replace or install a new HVAC system is around $7,500. However, the price can range from $5,000 to $12,500, depending on factors like the size of your home, the type and brand of the unit, and your specific heating and cooling needs. If you only need to replace certain components, the cost will be lower; for example, a new AC unit can cost between $2,200 and $5,500, while a new furnace costs $3,200 to $6,000. If additional work like new ductwork is required, the total cost could be as high as $22,000. It's best to contact a local HVAC company for an accurate quote.

Heat pumps are significantly more efficient than boilers, typically providing three to four times the amount of heat for the electricity they consume. While boilers run on fossil fuels, heat pumps use only electricity. This efficiency can lead to long-term savings on operating and maintenance costs. However, heat pumps have a higher upfront installation price compared to boilers. Despite their lower efficiency, boilers remain a popular choice for many homeowners, with 8 million in the United States alone, due to their lower initial cost and less intensive installation process. Ultimately, the best choice depends on your home's infrastructure, your budget, and your personal heating priorities.
