"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

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.

Most experts recommend getting three to five HVAC quotes from licensed, insured, reputable local heating and cooling companies. Getting multiple detailed HVAC quotes (but not too many) lets you compare the equipment, services, and prices of several contractors without being overwhelmed by options. It can also let you see if one contractor’s prices are much higher or lower than the others and give you a chance to ask for clarification. That way, you can weed out any contractors who aren’t providing quality services or materials and find the company that best meets your budget, quality requirements, and long-term goals.

Scale from hard water is hard to diagnose until it starts causing problems. If your area has particularly hard water, that’s most likely what your boiler is using. If scale build-up becomes a problem, it starts to cause decreased flow and heating, and eventually, valve failures as valves become blocked. Let boiler professionals know if you’re worried about scale and they can offer advice or implement a solution.

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).

No, boilers and water heaters are not interchangeable because they serve different primary functions. Boilers are used for central heating systems, providing hot water or steam to heat your home. In contrast, a water heater's purpose is to supply hot water for daily household use, such as for faucets and showers. A water heater alone cannot supply the warm water or steam needed for a central heating system.

While they are not interchangeable, it is common to have both a boiler and a water heater. In fact, a conventional boiler often works best when a water heater system is already in place. The two systems can be combined to provide both heating and hot water, either by pairing a boiler with an indirect water heater or by installing a premade combination boiler-water heater unit. For home heating, some homeowners may also opt for a furnace instead of a boiler.
