"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."

"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!

"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."

Install Boiler FAQs, answered by experts

Unless they are connected to the same system, boilers and water heaters will both need their own expansion tanks. The only case they wouldn’t have separate expansion tanks is if the boiler is pulling double duty and managing a heating system while also supplying hot water for a home. In which case, you may not need a hot water heater.

Professionals can recommend efficient layouts or appliances and ensuring regulatory compliance.

Hydronic and standard electric baseboard heaters differ in how they operate, their cost, and their performance. Standard convection heaters use electric coils to heat the air directly, while hydronic heaters warm a contained liquid like water or oil, which then radiates heat into the room.

In terms of cost and efficiency, hydronic heaters usually have a higher upfront price but are more energy-efficient and cheaper to run over time. This is because the heated liquid retains warmth, allowing the heater to continue providing heat for a while after the thermostat turns it off. In contrast, electric heaters provide heat more quickly but are less efficient.

Ultimately, the better choice depends on your priorities. If you need a room to heat up fast and have a lower initial budget, an electric heater might be suitable. If long-term energy savings are more important and you don't mind a slower heat-up time, a hydronic heater is likely the better option.

Installing a boiler requires training, a specific skill set, and extensive experience. Boiler installation can be extremely dangerous, as it involves working with water lines, gas lines, and electricity. For this reason, it’s strongly recommended that you hire a professional to install your boiler. Some states even consider it illegal to work on a boiler without the proper licensing.

If your boiler is 20 years old, it’s time to get a new one. Although it may seem to be working fine, it’s likely eating up more fuel than it should. Also, compared to a brand-new boiler, one that’s 20 years old is probably not working as well. When you get your new unit, you’ll notice that your home is heating more quickly, and the heat is consistent throughout all the rooms.
