"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.

"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

Many HVAC companies offer free quotes and free estimates for repairs and new HVAC systems. Others offer low-cost quotes or apply the cost of the estimates or diagnostics to your final bill if you hire them. Be aware that some companies advertise free HVAC quotes and recoup the costs by charging more for their services. Free HVAC quotes are never truly free—they cost the company time and effort—so be a good customer. Also understand that you may end up paying for free quotes in another way if you don’t hire a reputable company.

The cost to install a steam boiler varies depending on the type, fuel used, and your house size. The average cost to install a boiler is $5,900. You could spend $2,000 for a basic electrical steam boiler or up to $9,000 for a high-efficiency oil-burning steam boiler. Boiler installation is a job that’s best left for professionals to complete, and, in some states, only licensed installers can legally complete the job.

Costs depend on issue severity, parts needed, and labor rates.

If you hear your radiator clanking even when it’s turned off, it’s typically because there’s trapped water or air in the system, causing a pressure buildup. When you hear significant clanking, popping, crackling, or banging in a radiator that’s turned off, you’ll want to bleed the pipes or call in an HVAC specialist to deal with the problem (and prevent it from happening in the future).

The best time of year to purchase or replace an HVAC system, including components like an air conditioner or furnace, is during the off-season—spring and fall. During these periods, HVAC professionals are less busy than in summer and winter, when extreme temperatures create urgent demand. Shopping during the off-season can lead to savings of 10% to 15% on an AC unit and allows you more time to find the best deal and other cost-saving incentives. Typically, air conditioning units go on sale in the fall after demand drops, while furnace prices tend to decrease in the spring.
