"I called James to fix a sound problem on my laptop that my husband was unable to resolve. He came to my office and not only fixed that issue, but several others that he found.  Additionally, on a subsequent day, I was unable to print anything, called James, and he remotely fixed the issue.
I am VERY thankful that I found North Alabama Technical Services! James is professional and personable in addition to being extremely knowledgeable. He really knows his stuff, and I highly recommend him. Why waste time and energy trying to fix things yourself and add to your problems when you can have someone like James actually fix it quickly and the right way the first time? Plus there's no anxiety and cussing --- and everyone who has tried and failed to solve computer issues yourself knows what I'm talking about!
(P.S., I think our Angie's List account is in my husband's name, but this service was contracted by Kathy, not Mark.)

Boiler Repair FAQs, answered by experts

Most home boilers will need an expansion tank. That’s because these boilers are closed-loop systems, where the water is trapped. An expansion tank is needed when the boiler heats the water and it expands, allowing air to condense in the tank to make room for the water. Other types of boilers don’t use an expansion tank, such as traditional steam boilers, but these aren’t as common. And hot water tanks may be able to use a pressure release valve instead. When in doubt, call in a pro to take a look.

Yes, cleaning a boiler is essential for its efficient and safe operation. Over time, boilers can accumulate dirt, rust, sediment, and mineral deposits, reducing efficiency, increasing energy consumption, and causing potential breakdowns. Cleaning involves removing these deposits from various components like heat exchangers, burners, and pipes. Neglecting cleaning can also lead to corrosion and decreased life span. Regular, yearly maintenance, including cleaning, ensures optimal performance, lower energy bills, and a safer heating system. It's best to consult the boiler's manual or hire a professional technician for cleaning to ensure the job is done right.

Yes. Boilers need water to run without overheating, also known as dry firing. If you run it without a sufficient volume of water, either because of a burst pipe or a leak, you run the risk of damaging your machine or jeopardizing the safety of your home as a whole. When in doubt, shut off your boiler and repair any plumbing issues before turning it back on. Alternatively, consider installing a low-water cutoff (LWCO) before any issues arise. This gadget will protect your boiler by monitoring water levels and automatically shutting it off if it gets too low. 

At a minimum, an HVAC system should be serviced once per year. However, a twice-a-year service schedule—once in the spring for the cooling system and once in the fall for the heating system—is often recommended, especially for older systems, heat pumps, or in climates with extreme temperatures. Regular service, which includes inspection, cleaning, and maintenance, ensures the system runs efficiently, helps prevent costly breakdowns during peak seasons, and can extend the unit's lifespan. You can also schedule a service if you notice issues like poor performance or strange noises.

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.
