"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

The best time of year to purchase or replace an HVAC system, including components like an air conditioner or furnace, is during the off-season—spring and fall. During these periods, HVAC professionals are less busy than in summer and winter, when extreme temperatures create urgent demand. Shopping during the off-season can lead to savings of 10% to 15% on an AC unit and allows you more time to find the best deal and other cost-saving incentives. Typically, air conditioning units go on sale in the fall after demand drops, while furnace prices tend to decrease in the spring.

Overall, heating your home with an oil furnace tends to be less expensive than heating your home with an electric heating system. Oil heating systems stay warm for longer periods of time without drawing a constant electrical current to maintain a temperature. Plus, heating oil systems typically have a longer lifespan and lower price tag than their electrical counterparts, resulting in short- and long-term savings.

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. 

Some high-quality steam boilers come with 10-year warranties, but a well-installed, properly maintained model can last at least 20 to 25 years. Learning how to clean a boiler, getting an annual professional service, and keeping up with maintenance and repairs on your heating system are all important for getting the most out of your model. 

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.
