As COVID-19 continues to impact the global community, we at Blue Flame want to update you on the steps we have taken to ensure the safety of our employees and customers, please visit our website at www.blueflamecomfort.com for a detailed statement. Blue Flame Comfort specializes in residential install, service as well as maintenance with a 100% satisfaction guarantee. Ask us about tankless water heaters, high-efficiency furnaces, and heat pumps! Our office and standard hours are listed but our dedicated team of background-checked and thoroughly trained technicians are ready and willing to assist you 24 hours a day, 7 days a week for emergency services.

"If I could leave less than 1 star I would. Blue Flame markets themselves as a wholesome, family owned business, when in reality they're owned by American Residential Services (ARS), which is owned by the private equity company GI Partners. In the process of installing an AC unit, the technicians did not lay down a covering on our carpet, and got black grease all over it, which we still cannot get out. Then when they needed to install the thermostat, they punched numerous incorrect holes in our wallpapered walls. The whole hallway needed to be re-wall papered, and we cannot buy the type of wallpaper anymore. Mind you, this was in July, its now January and we're trying to have Blue Flame cover the costs, and they keep passing us off to a new person in the company. This is a typical private equity company move, where they hope you'll get frustrated and give up. We're now dealing with their insurance, who is lowballing us, and gave a burnt offering to repair one hole. Do not use them!"

"This company relies on AI and is not truly available 24/7. They sent a technician to my home who was unable to fix my issue, yet claimed it had been addressed. I called back immediately, and their AI bot booked me a new appointment that evening. The technician never showed. I called again over the course of the next two days, with no resolution. I received multiples text threads over the course of the two days stating that my concern had been escalated to the "on call manager," who never called. Today I spoke with the company and they said that there is no one in the office over the weekend! Despite my horrible experience, they refused to refund the cost of the "service." Take your business elsewhere!!!"

FAQs for central humidifier installation and replacement projects in Seattle, WA

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.
