"My overall experience was excellent! From the very beginning, the salesman, Austin, was absolutely amazing very knowledgeable, very pleasant and went way above and beyond to get things ready for my installation of a new heat pump system.The installation crew that came the following day was also absolutely amazing. I would highly recommend this company to anybody and will definitely contact them with any additional needs I may have. I’d like to thank each and every one of them for doing such an excellent, professional job."

"I like to research before choosing. I received 4 quotes for the job and Nick Buric was the only one that listened to our needs and created an option that was perfect for the space...as well as being at a reasonable cost. They did a really great job installing a slim "ducted" mini-split unit in a small concealed ceiling space in my basement. The unit is completely hidden and uses ducts & vents to provide efficient heat and AC in our basement -- it is super quiet too. These guys are real pros and did what was right & needed to best suit the house versus what would have been easiest for them -- the other firms I talked to didn't want to touch the job (quoted a traditional concealed mini-split mounted on the wall instead) but Nick had a vision and his team did it all to perfection. I will definitely use them again in the future and recommend to my friends and neighbors."

"Brad was great explaining everything from the work that needed done to the heat pump units themselves. I liked that he called prior to his arrival with an ETA . Did do a free estimate with us. We decided not to go with Tristate in the end and went with a small local business instead but Brad was super friendly and helpful."

"This company provided great service. Boris (the company owner) was very friendly, professional, and punctual. The car was a large SUV, in very new condition (though it smelled a little bit of smoke).  They also provided complimentary bottles of water and magazines, which was a nice touch. We were happy with his service and would recommend it.

Install Boiler FAQs, answered by experts

Radiators are a popular home heating choice in older homes, but they are becoming less common in new-construction homes. According to a 2022 report by Elements Visual Capitalist, only around 1.3% of new single-family homes have radiators and similar heating systems, such as baseboard heating.

While they may not be as popular as they once were, radiators today come with more energy-efficient features that can make them practical for modern homeowners.

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.

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.

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.

The cost of propane and related services varies depending on tank size and location but generally ranges from $500 to $2,500 for installation and initial fill.
