"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

The absence of heating or hot water, unusual noises like banging or gurgling, and visible water leakage are key signs. Abnormal boiler pressure, flame irregularities (for gas boilers), or pilot light issues may also signal trouble. Frequent cycling, soot or staining, and unusual odors, particularly gas-like smells, should not be ignored. Modern boilers often display error codes or lockout mode upon detecting issues. Uneven heating across radiators and rising energy bills without increased usage can further point to problems. Prompt attention to these signs is essential to prevent further damage and ensure safety.

While you’ll pay more upfront for a brand-new HVAC unit, you can save money in the long run. Here’s how to save on your new HVAC system:

  • When purchasing a high-efficiency system, your energy bills will be lower in the future.

  • You may be eligible for special offers from your local energy company.

  • Depending on the system, you may be eligible for HVAC rebates and tax credits.

  • Choose to replace your air conditioning unit and furnace simultaneously to save on labor and installation costs. 

The average cost to replace or install a new HVAC system is around $7,500. However, the price can range from $5,000 to $12,500, depending on factors like the size of your home, the type and brand of the unit, and your specific heating and cooling needs. If you only need to replace certain components, the cost will be lower; for example, a new AC unit can cost between $2,200 and $5,500, while a new furnace costs $3,200 to $6,000. If additional work like new ductwork is required, the total cost could be as high as $22,000. It's best to contact a local HVAC company for an accurate quote.

Boiler installations and replacements cost between $3,600 to $8,400. Expect to pay around $5,900 on average for a new boiler, including installation. Adding new radiators or heaters to the boiler may include separate costs if you are also upgrading those components, so the final price may be higher. To decrease costs, you can look for local energy rebates for using a boiler and wait until installers are offering discounts for a first-time installation.

You can use a boiler and a furnace, although it’s not common to use both for whole-house heating. For example, your furnace may take care of HVAC heating through your vents, while a boiler powers your floor-based radiant heating in the bathrooms. Mixing and matching like this gives homeowners a variety of heating possibilities.
