We take great pride in our experience, expertise, quality, and customer service that we provide to meet the consumer's needs. It is our mission to provide excellent workmanship and complete customer satisfaction from start to completion of a project. In order to understand the needs and expectations of our customers, we take great care to work and communicate with every customer in a professional manner. Our reputation is based on service, safety, and quality, regardless of how large or small the job.

"My understanding is that the guy that came out to install my new toilet and bidet has actually had more experience with commercial plumbing but you would never know it. He was very personable. Showed up a few minutes late but called and let me know he was running behind and then showed up when he said he would. Very conscientious. Seemed to know what he was doing with the bidet install even though it doesnâ t seem that would be typical for a plumber. Made sure everything worked as it should and then cleaned up after such that my wife couldnâ t even tell work had been done. His prices seemed reasonable. I have him scheduled to replace a water heater soon and just as an example his price is significantly less than the other two bids I got. And Iâ m not sure who it was that called but a few days later a woman called to see if I had had a good experience. Needless to say I answered YES!!"

Install Boiler questions, answered by experts

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.

Most propane boilers last 15 to 20 years with regular maintenance and proper care. The lifespan depends on the quality of the unit, proper installation, and the level of maintenance. Investing in annual service can maximize longevity and efficiency. Routine inspections and timely repairs prevent early breakdown, ensuring your boiler heats your home for years to come.

Fixing a radiator is worth it because it costs less than fully replacing it. Sometimes, a little troubleshooting can go a long way. The issue could be as simple as a blown fuse, a malfunctioning thermostat, or a loose valve. Plus, your daily life wouldn’t be too comfortable without a functioning radiator.

Warmed or cooled air can escape your home through drafty windows and doors. If you notice any gaps, be sure to caulk and seal them. You can also hire a local pro for an energy audit to get a list of energy-saving recommendations. 

Finally, check your insulation. It can settle in over time and become less effective. The Environmental Protection Agency (EPA) estimates that you can save an average of 15% on heating and cooling costs (or 11% of total energy costs) by sealing leaks and making sure attics, crawl spaces, and basements have a nice layer of insulation.

Always consult your manual for specific pressure numbers. Many expansion tanks come pre-pressurized at a specific PSI range, anywhere from 12 to 40 PSI, designed for a range of home boilers. You should not have to pressurize an expansion tank yourself, only the boiler system. If your system has a tank that needs to be manually pressurized, this is generally a job for professionals and their tools.
