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.

"A tech "Graham" came out for an annual maintenance visit on a reliable 15 year old York Furnace with a 20 year guarantee on the heat exchanger which Blue Flame installed in 2010. He could not explain why he was here, and when I told him "routine annual maintenance" he said, "Let's see what we can find". That was the first sign we had opposite agendas. It went south from there. After lots of loud grinding noises, he supposedly found a shiny jagged gash which he showed me on a scope. I am extremely suspicious he created it himself with a power tool. The end result was the furnace was no longer usable and cost me $8K to have them replace. To add insult to injury that guy ruined my screen door, which won't close anymore. I have ended my 15 year relationship with this company, since I no longer trust them."

We at Allred Heating, Cooling and Electrical hope to become your trusted friends and partners in keeping your homes safe, comfortable, and a pleasant environment for you and your families. How Allred Got Started Our company was founded by Dan and Matt who discovered they had complimentary areas of expertise. Matt began as an electrician about a decade ago and besides doing electrical work began working with HVAC as well. Dan had been doing contractor work in Alaska and when they met they realized they were a perfect match to begin a business, hence Allred Heating, and Cooling and Electrical. Between the two of them all of the right bases were covered to offer complete electrical and HVAC systems, both installation and repair. Allred Heating Family Hopes to Help Your Family We are a family owned company and we know how important it is to keep our homes working economically and safely. We hold ourselves and our work to the highest standards and that is why we offer a one year parts and labor guarantee. We are bonded, licensed and insured to and we’d like to show you why you can have the utmost confidence in us. We will give you upfront estimates so you’ll know what your bottom line will be.

"I recommended AllRed to my mother, they told her that they would give her a 10% discount on the phone when she called. They only gave her a 5% discount, they also didn't provide any information about the system? No information was provided also about health of system or checkpoint system used; (PSI of freon, lubrication, filters, drain lines, etc) When I called up Allred and asked for them to provide the 10% discount like they promised they said they would, and she would see it on her Credit Card. A couple of weeks went by and nothing. I called again, they apologized and said they would follow up ensure that the service team sent the information to us and provided the discount and called me back directly. After another week, NOTHING! While the work was completed successfully. The communication and follow up of this company are terrible to say the least. I wouldn't recommend Allred to anyone, or trust them at all :-("

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

Aim for indoor humidity between 30% and 50%, with the sweet spot around 45%. That range keeps mold, dust mites, and musty odors in check while protecting drywall and woodwork. Staying in the zone also helps your HVAC system run more efficiently and supports healthier air for you and your family year-round, during hot summers and cold winter months.

With routine filter changes and coil cleanings, most whole-house units run for eight to 15 years. Heavy use, poor air quality, or bargain-bin equipment can shorten that span, while a well-maintained, high-quality model often makes it to the upper end of the range. Ask your installer about recommended service intervals to get the most mileage from your investment.

It depends on your climate. Homes in cold, dry regions can often shut the dehumidifier off once winter sets in. If you live in a warm, humid area—or your house tends to trap moisture—you may need to keep it running year-round. Use a simple hygrometer: if readings stay below 50%, give the unit a rest. Just remember to restart it when humidity climbs again to avoid mold and condensation.

Dry air feels cooler, so your AC doesn’t have to work as hard. By stripping out excess moisture, the dehumidifier lets you raise the thermostat a few degrees without losing comfort. A shorter AC runtime reduces electricity use and can shave a noticeable amount off your summer power bill. Energy-efficient models further enhance those savings.

If your home is under about 2,000 square feet, a well-placed portable unit can handle the load. Just remember they’re less efficient and need hands-on upkeep—think emptying tanks and cleaning filters. If you prefer set-and-forget convenience or plan to expand your living space, a whole-house model still offers better long-term comfort and lower energy use per square foot.
