"My son and his wife who have three boys (one sick with the flu as the time) called me on a very cold February morning with his family homeless and a very cold house. After dealing with Home Comfort Systems, this is what he wrote and asked me to post: : While it was still very cold out,we smelled gas in our house. Nicor had us all evacuate. The next day, my parents recommended I call Home Comfort Systems the company which installed their new furnace a few years ago. Steve Bilica, one of the owners came out to my house before 10AM to provide me with a quote. The price was fair, I could tell he was honest and although he could've ripped me off easily as I was in desperate need. He offered fair payment options that worked with my tight budget. He contacted his supplier who delivered the new furnace before noon. A team of two brothers arrived by 1PM and began installation. They were extremely polite, considerate of my house, clean, efficient and clearly knew exactly what they were doing. By 4PM it was done and I had heat again. They even went the extra mile with some requests we had including removing an old, useless house-humidifier that was taking up space. Nothing extra for that. I was so relieved and glad that we could get back to normal and grateful to Steve and his company for their help."

"Tim came out for an estimate. He was professional and knowledgeable. Not pushy at all. On the day of installation, he and his team were respectful, efficient, and left our home clean. He thoroughly explained everything, and programmed the thermostat for us. We will use them for all future maintenance. Highly recommend."

"We just had Corey install our new Ecobee4 thermostat. He is quite possibly the nicest and most professional technician we have ever had in our home. He was meticulous and courteous. We will definitely call this company again, if we ever have any heating or cooling issues. 5 stars!!!"

Install Boiler FAQs, answered by experts

The best time to buy home heating oil is in the summer when the demand is lowest, as the prices are usually lower. However, waiting until the summer to buy is often unavoidable unless you install a separate storage tank. If you have the space for a second tank, you can expect to pay between $1,000 and $4,000 for the oil tank replacement or installation, depending on the capacity and location. You could quickly recuperate these costs, though, by stocking up on heating oil in the summer and avoiding deliveries in the winter when prices are highest.

Yes, you can build a sunroom addition to your home despite living in a cold climate. Make sure to use high-quality insulation and windows and to supplement with sufficient heating from your HVAC system. The windows in the sunroom allow enough natural light into the room to help heat it most times without having to use the furnace. Even a small electric fireplace can heat the sunroom well enough.

The absence of heating or hot water, unusual noises like banging or gurgling, and visible water leakage are key signs. Abnormal boiler pressure, flame irregularities (for gas boilers), or pilot light issues may also signal trouble. Frequent cycling, soot or staining, and unusual odors, particularly gas-like smells, should not be ignored. Modern boilers often display error codes or lockout mode upon detecting issues. Uneven heating across radiators and rising energy bills without increased usage can further point to problems. Prompt attention to these signs is essential to prevent further damage and ensure safety.

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 most important sign of a boiler problem is something happening unexpectedly, which is why regular boiler maintenance is important. Unexpected problems can include strange smells, new leaks, and unexpected noises that your boiler wasn’t making before. Additionally, if a boiler keeps shutting off or can’t maintain a specific temperature range, it’s time to call in an expert.
