"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."

"My heat pump had gone on the fritz just before I went out of town on May 20th. As soon as I returned on the 23rd I went about contacting contracting to get prices. I met with Lee, from ARS, on the 24th and agreed to a deal for a Carrier purchased through Home Depot. The installation was started and completed on 5/29. Great to have cool air again and lower electric bills. Would definitely use again but I suspect this unit may outlast me."

Install Boiler FAQs, answered by experts

If you're often struggling with radiator issues like chilly spots, leaks, or annoying noises, those are common indications that your radiator may need to be replaced. Corrosion, uneven heating, and persistent hissing sounds are common issues as well. When repairs become a regular chore and your home’s energy bills start to rise, a new radiator will bring the comfort and savings you need.

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.

If your boiler is 20 years old, it’s time to get a new one. Although it may seem to be working fine, it’s likely eating up more fuel than it should. Also, compared to a brand-new boiler, one that’s 20 years old is probably not working as well. When you get your new unit, you’ll notice that your home is heating more quickly, and the heat is consistent throughout all the rooms.

An expansion tank must always be installed on the supply side, which is the side where the boiler sends water out to heat the systems. That placement allows the water to push against the air and condense properly as it is heated, then circulated through the system. Professional installers can recommend the best place on the supply side for an expansion tank.

Boilers are equipped with multiple safety features to ensure safe operation. These include pressure relief valves to prevent overpressure, temperature high-limit switches to avoid overheating, and flame failure safety devices in gas boilers to cut off the gas supply if the flame goes out unexpectedly. Low water cutoffs prevent operation with insufficient water levels, and pressure gauges help monitor pressure levels. Ventilation and flue systems prevent the buildup of harmful gasses. Boilers often feature error code systems for automatic shutdown during malfunctions and gas leak detection for safety. Regular maintenance is crucial to ensure these safety features function correctly.
