"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."

"I contacted All Valley Solutions for my parents for a bathtub/shower remodel. My dad said Robert Hernandez was so great throughout the entire process of remodeling our bathtub/shower to a stand up handicap accessible shower. He walked my dad through the process of the remodel, answered all of his questions, was efficient with his time, and was always on time as well. And he came out to Los Fresnos for the job. The work was finished quickly and My dad will be hiring him again for other remodeling jobs. We highly recommend him for your remodel jobs. He also gave my dad a discount for being a veteran."

Install Boiler FAQs, answered by experts

An expansion tank must always be installed on the supply side, which is the side where the boiler sends water out to heat the systems. That placement allows the water to push against the air and condense properly as it is heated, then circulated through the system. Professional installers can recommend the best place on the supply side for an expansion tank.

DIY is not recommended due to safety risks and technical expertise required. Hire licensed professionals.

Boilers are equipped with multiple safety features to ensure safe operation. These include pressure relief valves to prevent overpressure, temperature high-limit switches to avoid overheating, and flame failure safety devices in gas boilers to cut off the gas supply if the flame goes out unexpectedly. Low water cutoffs prevent operation with insufficient water levels, and pressure gauges help monitor pressure levels. Ventilation and flue systems prevent the buildup of harmful gasses. Boilers often feature error code systems for automatic shutdown during malfunctions and gas leak detection for safety. Regular maintenance is crucial to ensure these safety features function correctly.

It can take anywhere from four hours to three days to replace a boiler with a new one. How long your particular boiler installation takes will depend on whether you need a gas line installed and if you’re switching to a new boiler system. 

Replacing a combination boiler or standard boiler with the same system should only take four to six hours. Meanwhile, switching from a conventional boiler system to a combination boiler system could take a few days.

Yes, government incentives and programs are available to encourage energy-efficient upgrades in many regions.
