"Climate Mechanics worked hard to make sure we had both systems replaced on the same day and before the summer heat started. Nathan provided excellent service and communication throughout the whole process, from the first visit through the install. We are very happy with our systems and are confident knowing we are working with a local company that will be there for the service and maintenance of the units."

"Lenny and his crew installed a new Lennox furnace for us. The team is courteous and professional. Lenny found that our old humidifier was installed at the wrong place because of the difficult duct work. He went above and beyond his responsibility and installed the new humidifier at the correct position. I greatly appreciate his honesty and utmost professionalism. It is no wonder that his company gets consistently high reviews."

"The job of the century! Martinelli’s crew did an outstanding job with our bathroom. From completely gutting our tiny master bathroom to finish. They completed our vision and then some. Mr. Steam steam shower, rain shower, Bain ultra air jet tub, porcelain and glass tile, marble vanity and marble shower floor. Recessed lighting and crystal vanity lights helped complete the look. I am so thankful for the hard work they put in to get our bathroom finished and could not be more grateful for the time they put in to get the job done by our deadline. Before and after pics attached to show their hard work!"

"Alliance service pros came to our house to find out why nothing was flowing from our house into my septic tank. They found that the pipe from the house to the tank was failing due improper installation when the house was built. Alliance arrived at our house before the time frame they gave me. They were up front with every charge throughout the process of identifying the source of our problem. A second truck had to be called in with extra equipment and supplies. They did not leave until our problem was solve. This company is honest, reasonable, professional and the guys are very kind. We would highly recommend this company."

"After buying a new refrigerator, Home Depot told me I needed a plumber to run a new water line to the refrigerator. I was not happy with the Home Depot tech that called me. The plumber, Dave, arrived soon after I called Harris and did a phenomenal job! He was friendly, professional and worked quickly. Thank you, Dave, and Harris Plumbing!!"

Install Boiler FAQs, answered by experts

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.

A home radiator works by using radiation and convection to transfer heat throughout your home. Electric radiators use metal to conduct heat and warm the air, which then rises to warm the room. Steam and hot water radiators work with a boiler and piping system to pump thermal energy throughout the home. Hot water radiators use a boiler to heat the water before circulating it to the radiator, while steam heating radiator systems convert the heated water to steam before circulating it out. When the water or steam cools, it travels back to the boiler to be heated again.

The cost to install a steam boiler varies depending on the type, fuel used, and your house size. The average cost to install a boiler is $5,900. You could spend $2,000 for a basic electrical steam boiler or up to $9,000 for a high-efficiency oil-burning steam boiler. Boiler installation is a job that’s best left for professionals to complete, and, in some states, only licensed installers can legally complete the job.

Coolant and antifreeze are technically not the same thing. The difference between the two is the ratio of water to other chemicals. True antifreeze is mainly made up of either ethylene glycol or propylene glycol, while coolant comprises one part antifreeze and one part water. However, the terms coolant and antifreeze are often used interchangeably, even by pros.

An expansion tank must always be installed on the supply side, which is the side where the boiler sends water out to heat the systems. That placement allows the water to push against the air and condense properly as it is heated, then circulated through the system. Professional installers can recommend the best place on the supply side for an expansion tank.
