"Furnace failed on 12/2/17. Excel came out on 12/4 (or maybe 12/5) to look at unit - told me it needed to be replaced. I shopped around for a bit then notified them on 12/14 that I wished for them to do the work. Furnace had to be ordered and installation was scheduled for 12/28. Excel called me on 12/27 to report that the furnace was still in Chicago - rescheduled installation for 1/2/18 which is when it was finally installed. On a positive note, everyone I dealt with at Excel was very respectful and polite. They arrived promptly and notified me 30 minutes ahead of their arrival, sending me texts with the names and photos of who would be coming. They worked efficiently and cleaned up extremely well after they were done. I noticed a problem with condensation leaking from a PVC pipe placed during the installation onto the top of the furnace. I called the office to report it and they promptly sent someone out to look at it. They ended up changing the configuration of the pipe which fixed the problem. They were again meticulous in their clean-up afterward. Other than being quite cold for a month, I was overall very satisfied with Excel Heating a & Cooling."

"Jason and Alex were on time and the job went well. Completed in approximately 5 hours. Jason explained why some equipment differed from the contract (provided part fit better into existing duct work). Jason noted that the internal components were the same. My wife and I purchased a mid priced unit. The price below reflects an approximate cost. The sales representative (Randy) wanted us to decide relatively quickly noting that now was a slower time for their crews. Working with Scott, Randy adjusted the quote. We had already received one other quote (liked the rep there) so we knew the Rescue Rooter proposal was competitive (even if we did not get truly a break). Our existing system was failing so we wanted to move forward. Jason and Alex explained what needed to be done to maintain the system and how to work the new thermostat. We purchased through Home Depot."

Install Boiler FAQs, answered by experts

If you’re looking for a way to heat your home that is lower in cost and higher in efficiency, you should run the numbers to see what it would look like to switch to gas or electric heat. The best choice for how to heat your home depends on your location, budget, and energy priorities.

Warmed or cooled air can escape your home through drafty windows and doors. If you notice any gaps, be sure to caulk and seal them. You can also hire a local pro for an energy audit to get a list of energy-saving recommendations. 

Finally, check your insulation. It can settle in over time and become less effective. The Environmental Protection Agency (EPA) estimates that you can save an average of 15% on heating and cooling costs (or 11% of total energy costs) by sealing leaks and making sure attics, crawl spaces, and basements have a nice layer of insulation.

Steam boilers require flushing at least every six to 12 months to keep them operating effectively for as long as possible. Depending on your water quality and frequency of use, you might need to do this more frequently. The flushing process helps to remove problematic buildup of sediments. While a boiler contractor near you can perform a thorough annual flush, learning how to drain the system yourself means you can do this monthly if you experience speedy mineral accumulation because of hard water. 

Professional HVAC installation requires licensed expertise in several areas, including electrical- and plumbing-related work. An HVAC team must know how to safely handle regulated refrigerant chemicals and the gas, oil, or propane used in furnaces and boilers. A proper HVAC installation protects your home from energy loss, fires, and even carbon monoxide leaks.

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.
