"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."

"Excellent. Diagnosed the issue, ordered the part, came back next day to install, and now furnace runs as it should! I have used this company 2 times now and will not call anyone else! 1) they are professional 2) HONEST, wont try to tell you that you need all these extra repairs that others will. 3) PRICE, I've found that their pricing is very reasonable and actually lower than others I've used, but that doesn't mean the service is any less!!!"

"Chose him due to the reviews and the price was right for my budget. The contractor who did the installation was good. Only thing I didn’t like was the fishing tactics like Mr Jackson was willing to upgrade the thermostat but after furnace was installed, nope. He said one I had was still good. Also the bullying to put in the reviews for the company. See that’s why he got 5 stars."

Install Boiler questions, answered by experts

Yes. In many cases, switching from an old furnace to a high-efficiency boiler can help you save money over time. You can also save money by switching from an electric boiler to a gas boiler, which costs much less compared to the energy bills an electric boil can create. Boilers are often (but not always) more efficient than furnaces, too. Then there are discounts, rebates, and incentives that can help you save on the initial costs.

In some cases, conversion kits are available, but not all boilers are compatible. Conversion may require significant modifications and should only be performed by a qualified professional. Before making a decision, compare conversion costs to the cost of a complete replacement to determine the most cost-effective and reliable option for your home.

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.

Heat pumps are significantly more efficient than boilers, typically providing three to four times the amount of heat for the electricity they consume. While boilers run on fossil fuels, heat pumps use only electricity. This efficiency can lead to long-term savings on operating and maintenance costs. However, heat pumps have a higher upfront installation price compared to boilers. Despite their lower efficiency, boilers remain a popular choice for many homeowners, with 8 million in the United States alone, due to their lower initial cost and less intensive installation process. Ultimately, the best choice depends on your home's infrastructure, your budget, and your personal heating priorities.

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.
