"Guardian Heating and Cooling was very professional putting in our new boiler system. Steve was on time, explained everything that was going on, answered any questions about the project, was efficient professionally, and left the area as if there was no work that had happened there. In my opinion an A+ service."

"Sparky was great.  He assessed the problems and fixed all of them in an efficient manner.  He really knows his stuff.  My track lighting was totally screwed up - he had to get up in the attic and run new wires and install a new switch.  He knocked it out of the park.  6 months later, all things that he worked on are working great.  Highly recommend his services."

"They came out and looked over the A/C unit. I told him it makes a very loud banging when it starts up and that the company who installed it told us that was normal and it was working fine. Once he was done cleaning the unit, he went to restart it and it tripped the breaker. So he took it apart and found that when it was installed, someone had pinched a wire, cutting the insulation and causing it to short out on the frame of the A/C unit. He fixed that, reassembled the unit and restarted it. It's still a loud start, but not nearly as loud as it was. He informed me that our A/C is a builder grade model and unfortunately it's not the best on the market so it's going to be louder than we would like. Once he was done working on the A/C, he came in and took a look at our furnace to make sure it wasn't hooked up wrong also. Definitely will be calling on Faithful again."

"Very prefessional and thorough. Left my place clean after the install, and even loaned me some goo-be-gone from their toolbox for a project that I was working on while they were installing my furnace. They reviewed what they did at the end, and gave me a card so that I could call with any issues. Would highly recommend Sears and their contractors."

Install Boiler FAQs, answered by experts

While you’ll pay more upfront for a brand-new HVAC unit, you can save money in the long run. Here’s how to save on your new HVAC system:

  • When purchasing a high-efficiency system, your energy bills will be lower in the future.

  • You may be eligible for special offers from your local energy company.

  • Depending on the system, you may be eligible for HVAC rebates and tax credits.

  • Choose to replace your air conditioning unit and furnace simultaneously to save on labor and installation costs. 

Steam boilers require flushing at least every six to 12 months to keep them operating effectively for as long as possible. Depending on your water quality and frequency of use, you might need to do this more frequently. The flushing process helps to remove problematic buildup of sediments. While a boiler contractor near you can perform a thorough annual flush, learning how to drain the system yourself means you can do this monthly if you experience speedy mineral accumulation because of hard water. 

A furnace is a big unit where gas, heating oil, or electricity heats the air. The warmed air is then pushed back out through ducts and vents. 

A boiler uses electricity, heating oil, or gas to heat water that is pushed into the room through a radiator. This is one of the oldest and most effective ways to heat a house, but radiators can also be unsightly and leave hot and cold spots in the room.

Heat pumps use a refrigerant to move heat from outside into the house and return it to the room through ducts and vents.

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.

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.
