"Service technician was very professional. He took time to show me what had to be fixed and explained how it would improve furnace performance. He took the time to make certain I was satisfied with the outcome. He tested the systems to check they were in good working order. Finally we have excellent customer service."

"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.

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

Boiler installations and replacements cost between $3,600 to $8,400. Expect to pay around $5,900 on average for a new boiler, including installation. Adding new radiators or heaters to the boiler may include separate costs if you are also upgrading those components, so the final price may be higher. To decrease costs, you can look for local energy rebates for using a boiler and wait until installers are offering discounts for a first-time installation.

The cost of heating oil fluctuates rapidly based on supply and demand, but the average price is between $4.00 and $4.50 per gallon, which means filling a standard 275-gallon tank would cost between $1,100 and $1,240. Much like automotive gasoline, the price of home heating oil changes constantly, so the only way to get an accurate and current price per gallon is to contact a heating oil delivery company. Some companies also offer contracts with a set price that should be an average cost over the contract term.

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.

The best way to compare HVAC quotes is getting a few detailed quotes from local companies with good reputations. Then, go over the quotes line by line. Protect yourself by insisting on in-person estimates that include equipment manufacturer names, model numbers, SEER ratings, amounts and numbers of materials, details of warranties on equipment and labor, and other specifics. 

Knowing the exact equipment and materials is the only way that you can fairly compare quotes. Quotes that are much lower than others can be a sign that the company isn’t providing the best quality service or materials.

A home radiator works by using radiation and convection to transfer heat throughout your home. Electric radiators use metal to conduct heat and warm the air, which then rises to warm the room. Steam and hot water radiators work with a boiler and piping system to pump thermal energy throughout the home. Hot water radiators use a boiler to heat the water before circulating it to the radiator, while steam heating radiator systems convert the heated water to steam before circulating it out. When the water or steam cools, it travels back to the boiler to be heated again.
