"Computer did the "gotta send info to Microsoft" but when tried to reboot it ran through automatic repair without success. I did all the alternative without any success. He came and picked up the hard drive on Tuesday and returned it on Saturday. Fortunately he was able to "restore" without any data loss. Very happy with outcome."

"Not only was ultimate air on time, they did a good job cleaning our system, and now we can breathe clean air, keeping me and my family healthy. They also explain in detail why it wasn’t blowing as strong, and showed me how dirty it was, and explain that it needs at least a cleaning every six months. Definitely would recommend and will be hiring them again. Thank you ultimate air!"

"Had a leak in my kitchen faucet and it caused my cabinet base to rot. Willis came within a few days after contacting his business and changed out my faucet, removed the rotted wood and replaced the base. 100% satisfied with the service and will 100% definitely recommend his services. Honest, reliable and reasonable on his pricing. His years of experience in general contracting definitely shows with his professionalism. Thanks for the great service Willis!!!"

"Wonderful.  They did a great job of  engineering the PV needs for house, installing system, cleaning up afterwards.  We are so happy we used Revolusun for our PV!  And the great cost savings, of course!

Install Boiler questions, answered by experts

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

Safety concerns with propane boilers include proper venting to prevent carbon monoxide buildup, secure gas line connections, and regular inspection of safety controls. Professional boiler installation and annual maintenance are essential to minimize risks. Having a carbon monoxide detector installed in your home is essential for early detection of any leaks or ventilation issues.

In most cases, repairing a radiator is more affordable than replacing it. A typical repair may cost between $100 and $200, while a replacement can average $1,500, with a range of $250 to $2,500 depending on the unit type. Radiator issues are often simple fixes for a professional, such as a blown fuse, malfunctioning thermostat, or a loose valve, and can take less than an hour. However, if the long-term costs of fixing the radiator are higher than replacement, it's better to get a new model. It is recommended to consult a heating expert to diagnose the problem and determine the best solution for your situation.

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.

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.
