"Outstanding from first meeting & purchase to 24Kw Generac's first start up. Amanda Tallman is completely thorough explaining all installation steps & the numerous items pertaining to this model. On the final day, in the rain, alone Amanda improved the propane line installed by gas supplier. We were so grateful for installation before cold weather & frozen ground occurs. Completely SATISFIED with 4 POWER NOW Roger Sevilla Throop Township."

"I called Green Homes, Home Depot, and Comfort for estimates.  Prices for Green Homes and Home Depot were nearly identical.  Green Homes took more time to explain the features of the windows, show a sample, give considered opinons on options when I requested them, and didn't have extra costs that Home Depot did.  I ended up cancelling the comfort estimate.  I've used them before, and was happy to try someone else. 
They came out right away for the final measurement and gave a tentative date for install.  I called a week or so later, and they confirmed the date, which was only about 3 weeks.  Just after 5 on the Friday before the install I realized I never got a confirmation call, and they were closed so I couldn't call.  But no worries, at about 8:30 Monday morning they pulled in.  Jeff, Jeff, and Mark were great all day.  They did the rooms that I needed done first first, and the room that I  needed last last (moving some furniture around).  They got the inside work on the 12 windows, including trim replacement, done day 1.  Day 2 they arrived again about 8:30 and quickly installed the slider door, then began the outside wrapping.  In the pouring rain.  They're due back for about 1/2 day tomorrow to finish the wrapping outside. 
The windows seem like very good quality.  They missed the grids on 1 window, but the guys knew it and told me as soon as they arrived on day 1.  They installed the wrong window, and will be back out when the correct one is received.
I wouldn't hesitate to call these guys again for service.

"The whole experience from start to finish was very professional and friendly. The team was in constant contact with us to make sure all of our questions were answered. The installer reviewed the process with us before he started and then gave a run through on how to use the new furnace and again asked if we had any questions. We will definitely recommend Sears to our friends."

Install Boiler questions, answered by experts

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.

Installation costs range from $4,000 to $12,000, depending on unit size, efficiency rating, and labor.

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.

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.

The cost-efficiency of baseboard heaters depends on the type and how you use them. Generally, standard electric baseboard heaters can be expensive to run because they use electric resistance heating, which is less energy-efficient than systems like forced-air or heat pumps. However, hydronic and gas versions are typically much cheaper to operate. Hydronic models are more energy-efficient because they heat a liquid that retains warmth longer, preventing the thermostat from turning on and off as often. The overall running cost is also influenced by local electricity rates, your home's insulation, and your usage habits. To increase efficiency, you can use baseboard heaters for zoning, meaning you only heat the specific rooms you are using.
