"Huge thanks to Tuck & Howell Plumbing, Heating & Air for taking such great care of us! JD came out to inspect and clean our AC, and uncovered a clogged drain line. Now it’s running like a dream—just in time for the summer heat. He was professional, knowledgeable, and super friendly. From start to finish, the experience was top-notch. It’s clear this company truly cares about their customers. Highly recommend!"

"Jim Farrell and North Alabama Technical Services rebuilt my computer and provided me with everything I expected and so much more.  He provided the various options in equipment, including specs and pricing, answered all our questions and helped us make the best decision for our purchases.  The computer was completed in a few days, far less than expected, the installation included clear directions for use.  The package also included a good warranty for the equipment.  I was extremely pleased with his service and would not hesitate to recommend his company to anyone with computer service needs."

"After giving us an estimate in Dec 2014 and constantly following up with us they earned our business. They installed 8 piers and 3 beams under our home and what a difference! Just walking across the floors feels so sturdy. Now that this has been completed we can begin working on our kitchen remodel. Thanks Again!

Install Boiler FAQs, answered by experts

Boilers provide even heating, energy efficiency, and a quiet operation compared to forced air systems.

Oil boilers provide reliable heating, efficiency, and long-term cost savings compared to electric options.

If you go to turn it counterclockwise and it won’t turn anymore, it’s open. Like most other valves, you should be able to turn a radiator valve counterclockwise (to the left) to open it and clockwise (right) to close it. To close a radiator valve, turn it clockwise until you meet some resistance and can’t turn anymore, but do so carefully to avoid breaking the valve.

Generally, an oil furnace is considered safer than a gas furnace for several reasons. While both types of furnaces can produce carbon monoxide, a leak in an oil furnace is easier to detect due to the smell. Oil furnaces also don't connect to a gas pipeline, which reduces the chance of a fuel leak. Most importantly, heating oil is not combustible, whereas natural gas is highly flammable. This means there is a much lower risk of combustion or explosion with an oil furnace. However, an oil furnace can still pose a fire hazard if it tips over.

Most propane boilers last 15 to 20 years with regular maintenance and proper care. The lifespan depends on the quality of the unit, proper installation, and the level of maintenance. Investing in annual service can maximize longevity and efficiency. Routine inspections and timely repairs prevent early breakdown, ensuring your boiler heats your home for years to come.
