"Wahl was able to provide same-day service on my furnace that had shut off in the midst of our first snowfall this year. Within 2 hours of arriving, they diagnosed and fixed the issue. They recommended replacement options in the next year, but weren't pushy about me spending that type of money now, which I appreciate. I'd recommend their expert, timely team to anyone!"

"The installers were punctual. They were very professional and friendly. They cleaned everything up before they left. There was no mess. I was very satisfied with the whole process. It's only been a few weeks since the installation so I am not able to comment on the longevity of how the units run over years or the service department."

"Had wade install a Mitsubishi Mini Split with 4 ceiling units on the 2nd floor to assist with heating and cooling issues. The whole process was easy from beginning to end with very clear and quick communication. Also had them repair an existing system at the same time that was quick, hassle free and got me fixed up properly. I want to especially thank Lonnie, Mr Wade and the Installers for their expertise and professionalism along the way. I am extremely satisfied with the Mitsubishi units that were installed and would highly recommend their services!!!"

"When our pipes leaked, it was a really bad time. A lot of people in West Virginia had frozen pipes because there was a bad storm. There was at least 20 or 30 before us so they worked them, and they got to us in a day and a half. Considering what they had ahead of them, we know they must have worked overnight."

"I purchased the diagnostic service call from angie's list on Sunday, and on Monday morning Brian called me and came over the same day...He was extremely prompt, courteous, and knowledgeable...he took out the time to thoroughly explain the reason behind the leak, a low level of refrigerant, and fixed it in no time...he returned the next day to install a drainage pump for the condensed water...All was done very professionally and cheerfully, always explaining every step in detail.....aside from his professionalism, Brian is a very kind and helpful guy, and I can honestly say that he was by far the best contractor I ever hired....the job turned our great, and I'm enjoying my cool house in this heat...Thank you so much for a great job, Brian....I will call you in the fall to check my furnace for the winter"

Install Boiler FAQs, answered by experts

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

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.

The best time to buy home heating oil is in the summer when the demand is lowest, as the prices are usually lower. However, waiting until the summer to buy is often unavoidable unless you install a separate storage tank. If you have the space for a second tank, you can expect to pay between $1,000 and $4,000 for the oil tank replacement or installation, depending on the capacity and location. You could quickly recuperate these costs, though, by stocking up on heating oil in the summer and avoiding deliveries in the winter when prices are highest.

If your boiler is 20 years old, it’s time to get a new one. Although it may seem to be working fine, it’s likely eating up more fuel than it should. Also, compared to a brand-new boiler, one that’s 20 years old is probably not working as well. When you get your new unit, you’ll notice that your home is heating more quickly, and the heat is consistent throughout all the rooms.

Installing a boiler requires training, a specific skill set, and extensive experience. Boiler installation can be extremely dangerous, as it involves working with water lines, gas lines, and electricity. For this reason, it’s strongly recommended that you hire a professional to install your boiler. Some states even consider it illegal to work on a boiler without the proper licensing.
