"Kyle was amazing, in that he provided timely and accurate answers to all of my questions. They showed great respect for my home. The entire process of working through the options and their explanation of each one was top-rate.
I really wanted to go with them as a company, but for the exact same equipment, another bid was about two-thousand dollars less.
I still wish their price had been closer, as I would have been willing to pay a slight premium to have them do the installation.
The impression I received was that their bids are usually very competitive. They were genuinely surprised that another bid was lower and puzzled over how the other company could provide the same equipment for less.
I would recommend Kyle and Sun Glow to anyone looking for an honest, respectful company to install heating or air conditioning equipment.

"Furnace stopped working Sat evening, called and scheduled for next day service call. Corie showed up on time. He was courteous and professional. After a few minutes of checking various connections, he diagnosed the problem(loose connection). After fixing the problem and making sure it was working correctly, he cleaned up his work area, and left."

"I purchased an Angie's List Big Deal for this service and it was okay. They did a good job, but in the course of trying to sell me another service they pulled up a floor vent and made kind of a mess in my hallway, which I was not super-happy about, but it was not the end of the world. He did not ask me if he could pull up the vent and if he would have asked me I would have told him not to do it. This was the first time I used this company. They were very fast and efficient with the dryer vent cleaning and I have no complaints about that at all. I had a little trouble getting the service scheduled."

"Phone calls were answered promptly, and the estimator arrived within a week and provided a written estimate on the spot - far better service than the 2 other companies we called for estimates. Alpha Energy was running a special for the month of July, so the price was very competitive. The team that came to do the work was on time and efficient. The only problem was a miscommunication between the estimator and the work crew. We were told that they would be able to remove the siding and drill holes on the exterior to install the insulation - but the work crew thought they were to drill holes on the inside. They were not able to remove the siding without cracking it, so we had them do the installation from the inside. The work was perfectly fine, but did not include patching of the holes in the walls. This was not the fault of the work crew - they did a fantastic job. I would just recommend having everything spelled out in the estimate to avoid misunderstandings."

Install Boiler FAQs, answered by experts

Due to fuel line connections and venting complexity, professional installation is required for safety and efficiency.

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.

Some high-quality steam boilers come with 10-year warranties, but a well-installed, properly maintained model can last at least 20 to 25 years. Learning how to clean a boiler, getting an annual professional service, and keeping up with maintenance and repairs on your heating system are all important for getting the most out of your model. 

The radiators closest in proximity to the boiler heating system will heat up first. Radiators in rooms farther away from the boiler will take longer to heat up and may be the coolest rooms in the house. The radiator unit itself should heat up evenly; otherwise, there may be trapped air inside it.

If you want to have hot water in your home and part of your plumbing system, you'll need a hot water heater. An alternative may be to heat water as you use it, such as by boiling what you need on the stove. But that's much less efficient and takes considerably longer than hooking up a water heater. Another option is to rely on appliances, such as a dishwasher or washing machine, that heat the water themselves.
