"Better than expected. Phil was the only contractor that responded AND came to my house on the same day that I called all the other contractors. He provided me the potential problem for my heat pump issues on the phone that eventually was confirmed during his initial visit and then during disassembly of the old duct system. He was very helpful in providing me additional savings and existing tax credits for the Attic Breeze vent system installed including for the heat pump providing me with the forms. Swift service done on a short time from initial call to complete installation (less than 1 week and completed installation in 7 hours). Great job by the technicians on the installation and housekeeping after the job was completed. Ben A."

"SAVED MY 84 y.o. MOM'S & MY DAY/WEEK!! Incredible service! Mom's 84 in Summerville, I live in California... Right off the bat, Sammy, the biz owner, responded, within 5 mins of yelp request. He gave me a price that was flat rate and VERY reasonable. Didn't need to set appt to come (days later) to give an estimated (over-priced) bid. (All via yelp msging) I told him I was going to buy new Rheem water heater at Home Depot. He offered to pick it up to save me the delivery charge and not charge more money!$$$ He could do it same day or next AM. I AGREED. Bought unit online from Home Depot in Summerville. Made him the contact pickup person. Sent him the order #. He picked it up. Took out & away the old unit (rusted out bottom) and put in brand new unit / cleaned up the mess) this was all done by 7pm on the SAME DAY!! I didn't order the unit until almost 1pm. He msged me a chase bank credit card payment link to pay. Easy & secure. My Mom was VERY HAPPY & GRATEFUL to Sammy at KLC. I was so HAPPY with how it all turned out I asked him if he had Venmo or cash app and sent him more money $$ directly!! Very grateful... DEFINITELY CHOOSE SAMMY if you need REAL HELP and need a good Friend in the Plumbing or HVAC BIZ."

"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

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.

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.

There are several types of home radiators, and the most common are steam heat radiators, electric radiators, and dual-fuel radiators. Steam heat radiators are connected to a boiler. Electric radiators can operate without being connected to anything else—they just need an electrical outlet. If you have a dual-fuel radiator, you’ll see a valve at the bottom of the system with a wire coming out of it and going into a wall. These are often your towel radiators in the bathroom. The type of radiator you have will impact how you turn it on.

The radiators closest in proximity to the boiler heating system will heat up first. Radiators in rooms farther away from the boiler will take longer to heat up and may be the coolest rooms in the house. The radiator unit itself should heat up evenly; otherwise, there may be trapped air inside it.

Heat pumps are significantly more efficient than boilers, typically providing three to four times the amount of heat for the electricity they consume. While boilers run on fossil fuels, heat pumps use only electricity. This efficiency can lead to long-term savings on operating and maintenance costs. However, heat pumps have a higher upfront installation price compared to boilers. Despite their lower efficiency, boilers remain a popular choice for many homeowners, with 8 million in the United States alone, due to their lower initial cost and less intensive installation process. Ultimately, the best choice depends on your home's infrastructure, your budget, and your personal heating priorities.
