"My technician Keith was great. Friendly and super informative. Also too a quick look at the entire drainage system and gave my an idea of where problems will pop up the future without preventative measures (my home was built in the 50s and while the previous owners took really good care of the house nothing has been gutted and replaced yet)."

"As mentioned in my review for their dryer vent coupon... you must watch the fine print!  My $199 air duct cleaning cost around $500 once completed.  I did expect an upcharge on this service but not quite that much.  Frankly, other Angie's List air duct services would have come in less with a more "honest" coupon price.  I doubt many customers will get the $199 deal without any upcharges.
Having said all that, the receptionist, Danella, was very courteous and responded quickly.  She was great with a last minute rescheduling due to our closing on our new house being delayed a few days.  The service people were professional and arrived on time as scheduled.  They appear to have done a good job.

"Jeremiah was excellent.  He came to my house on a Saturday to accommodate my schedule, gave me a accurate and beyond reasonable quote and scheduled/completed the work within a week.  During the install we ran into several problems which he took care of quickly without any additional cost/fuss.  He is an excellent person to work with and took care of me from start to finish.  Can't recommend highly enough; he's my go-to heating/AC guy from here on out.  He also does plumbing so... he can be your go-to person too for most issues!  Not sure where the very few negative reviews come from but anyone who isn't a pain in the rear will appreciate Jeremiah immensely.  Thanks again!

"My computer (Windows XP) was running very slow and had become almost inoperable. It was taking a very long time to process anything, especially anything to do with the internet. IE was taking 100% of the cpu most of the time. Jim worked on my computer remotely for several days defragging, cleaning, anti-virus, malware, etc., but could not get it to perform anywhere near where it should. We decided that I needed a new computer. Jim built me a new computer (Windows 7 with racing stripes). The new system works very well and I am pleased with it. When Jim switched my files over from old to new, the Kodak Easy-Share program with my pictures did not get transferred. He has promised to make that transfer when he installs a new door covering the DVD reader which was broken upon setup. I will update this review when this occurs. I am very pleased with the new system and would do it all over again if a similar situation were present.

Install Boiler FAQs, answered by experts

All modern boilers are condensing boilers because they’re the most efficient type. Instead of extra heat leaving through the flue, these boilers trap the heat and use it to heat the house. Whether you choose a combi boiler, system boiler, or regular boiler, you can opt to get a condensing system. If you have an old boiler that’s not a condensing boiler, it’s a good idea to get an upgrade.

There are several types of home radiators, and the most common are steam heat radiators, electric radiators, and dual-fuel radiators. Steam heat radiators are connected to a boiler. Electric radiators can operate without being connected to anything else—they just need an electrical outlet. If you have a dual-fuel radiator, you’ll see a valve at the bottom of the system with a wire coming out of it and going into a wall. These are often your towel radiators in the bathroom. The type of radiator you have will impact how you turn it on.

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.

Since your boiler keeps you warm and provides hot water to your home, you’re likely to notice issues with heating in your living space right away. The most obvious sign that your boiler is breaking is not getting any heat or hot water. You might also hear some odd sounds coming from your boiler during operation, the flame in your gas boiler is not blue, the pressure is inconsistent, or your boiler is using more energy than it should. If you notice any of these signs, be sure to call a pro right away.

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.
