"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."

"

I noticed in our mail thing that we are due for service on our system to keep our warranty up; to do so we are actually going to do a maintenance contract with them  it is about $96 yearly, but they come out and do inspections and everything. The owner is the one who came out and gave us a quote. We had them replace another system which was nor working correctly so the first the thing they did was send someone to inspect the old system to see what were the problems. They fixed it on the spot for free and did not even charge us to come out. They were very nice, courteous and stayed in contact with us the entire time. They were very nice, professional and they got the job done in an efficient manner. They did not charge us an insane amount of money for it. We had a name brand system. It was a well worth investment to have it done right.

"It was an outstanding experience from start to finish. The floor sanders left my heat pump running while sanding. I replaced my duct filters three days in a row because they were filled with dust and debris. I needed help in a hurry, and Keith went out of his way to make it happen so my painters could arrive on time. I also had electrical work happening on the same day so the power was turned off. Keith went above and beyond to find a portable generator and complete the work. It was an all day job in the heat, and Keith got it done. My vent filters have been sparkling clean for the five days since he did the work. I highly recommend this company."

"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."

"This was the best service I have ever received from a HVAC company. The guy worked on my furnace for over an hour until he fixed it. It ended up costing for the service call only due parts not being added to the furnace. He was very personable and did a great service for me. I will always use this company for my needs in the future."

"My experience with Hometown Heating and Air was excellent from start to finish. Geothermal system was replaced with a new efficient Heil heat pump. A Durastar mini split was added to my kennel building. Both systems are working perfectly. Owner Caleb Hanks has been patient, informative, punctual, available to answer questions; all with a cheerful smile. Very grateful and very satified with my expenditure. Very Highly Recommend Hometown!"

FAQs for central humidifier installation and replacement projects in Roanoke, 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.
