"It went splendidly.. I couldn’t have been more impressed with the professionalism of the installer, Scottie Fralin! He made a recommendation as to complete replacement of toilets which he obtained for me since I am elderly and have neuropathy in my hands and arms, making purchasing and handling the pickup of not one but TWO commodes daunting. He cleaned up the areas after he completed the work, leaving me “good to go”! I suppose I didn’t realize the old commodes were nearly 30 years old. I’m pleased with the replacement choices! Thank you Scottie! And thanks for your patience with my chatter."

Wisler Plumbing, Heating, Cooling & Electric proudly serves Roanoke and surrounding area, all of Franklin County, and everyone located around Smith Mountain Lake. \n \nWhen our dad Daniel Wisler put our name on his business back in 1986, he committed to doing what was fair and right. He led by example and he taught us to do the same. He taught us to stand up, work hard through adversity; to take responsibility for our mistakes. It's not easy, but it's the difference between a business that survives and a business that thrives. \n \nWislers' foundation of beliefs lights our way, from policies we live by to the people we hire.

"Ostrom showed up to do the work exactly when they said they would be there and they did exactly what they said they would do (which is a little rare these days). The work was very professionally done and everything was cleaned up when they left.  The drywall repair work around the tub/shower surround was VERY well done also. Their price was not the lowest bid I got, but this was an example of "you get what you pay for." I would recommend these folks to friends.

"I called James to fix a sound problem on my laptop that my husband was unable to resolve. He came to my office and not only fixed that issue, but several others that he found.  Additionally, on a subsequent day, I was unable to print anything, called James, and he remotely fixed the issue.
I am VERY thankful that I found North Alabama Technical Services! James is professional and personable in addition to being extremely knowledgeable. He really knows his stuff, and I highly recommend him. Why waste time and energy trying to fix things yourself and add to your problems when you can have someone like James actually fix it quickly and the right way the first time? Plus there's no anxiety and cussing --- and everyone who has tried and failed to solve computer issues yourself knows what I'm talking about!
(P.S., I think our Angie's List account is in my husband's name, but this service was contracted by Kathy, not Mark.)

"Mr. Tilley is to great work with and very knowledgeable. He came out the same day I called and validated my findings. Late the night before it was scheduled to install the unit I called to go ahead and replace my second aging unit as well. To my surprise, his crew showed up and installed both units the next day. I wouldn't hesitate to recommend Mr. Tilley to anyone that has HVAC needs."

"We are pleased to recommend Triangle Reconstruction with our highest praise. It seems too simple to say that they do what they said they’d do, but that’s exactly what happened. Our home is around 50 years old. Ours was a large job - around a month and $30,000. We had Triangle Reconstruction come in after another moisture company provided mold remediation and a humidifier. I wish we’d contacted TR to start with. We provided TR with a structural engineering report. They created a plan to exactly meet all of engineer’s concerns. TR used temporary supports and replaced seal plates, girders, and joists for over half of our home. In addition, they poured footers and built new columns. They also added a few additional girders to firm up our floors. They removed and replaced our insulation. They sealed our porch and crawl space, replaced our vapor barrier, and installed a moisture meter. They wrapped our electrical cords and hung them. The people at TR are remarkable. A+++++"

"Very good! Chris called me almost immediately after I registered on Angie's List. I had already been told by my regular HVAC service tech that a replacement unit would cost about $7000 if paid in cash or offered me a financing/service contract for 10 years at $140+ a month!! Come on guys! Chris with B&B came by the next day (Monday), we talked and he offered to replace my current Goodman units with slightly better rated ones for $4500 and would do it the next day! He and his assistance were done in under the 3 hours the next day that Chris said it would take. Very happy with the products and the services so far!! He even honored the $100 coupon that was on your site."

FAQs for central humidifier installation and replacement projects in Salem, VA

A crawl space dehumidifier is a worthwhile investment, particularly in humid climates or if you've noticed musty odors, mold growth, or wood deterioration. Though costs range from $3,000 to $9,200, this investment helps prevent structural damage that could require far more expensive repairs later. Beyond structural protection, a properly dehumidified crawl space contributes to better overall indoor air quality and may reduce allergens throughout your home. Consider having a professional assessment to determine if your specific situation warrants this investment.

Addressing crawl space moisture effectively often requires a combination of solutions. A complete approach includes encapsulation plus dehumidifier installation. For minor moisture issues, a basic dehumidifier starting at $1,500 may suffice, while severe problems in larger spaces could require systems costing up to $14,000. The most effective moisture control strategy depends on your specific conditions, making a professional assessment valuable for determining the most cost-effective approach for your situation.

For a crawl space measuring 1,500 square feet, you'll need a dehumidifier with a daily capacity of 30 to 50 pints, with unit costs ranging from $150 to $600. Your local climate and existing moisture levels may necessitate adjusting this capacity—homes in particularly humid regions might benefit from higher-capacity units. Professional installers can measure your specific humidity conditions and recommend equipment that is appropriately sized, balancing initial cost with operating efficiency for your unique situation.

Crawl space dehumidifiers add $300 to $500 to your annual electricity expenses when operating continuously. Energy-efficient models reduce this consumption by roughly 15 to 30% compared to standard units. Most contemporary dehumidifiers feature humidity sensors that automatically cycle operation based on current conditions, helping manage energy usage. Proper crawl space encapsulation significantly improves efficiency by creating a controlled environment that requires less dehumidifier runtime, thereby reducing ongoing electricity costs.
