"It was way too expensive for the work that was performed. They originally said that the pipes leading up to the faucet may need to be replaced and the wall opened up. Previously before engaging them. I asked for a possible quote for how much it would cost and they told me that it was up to the technician. When they came out to do the work that they would determine the amount. I asked the technician how much it would and he told me that it was up to the company to decide for how much the work would cost. When I contacted the company they told me again that it would be up to the technician to determine the how much it would cost by checking the amount of work. I could not get an answer from both of them because they would just keep passing each other on who to ask for the quote. After the project was completed, I was given the bill of about $750+ to replace the faucet, to replace the hoses and the two knobs roughly $350+ each. When I called the company about the price, I was transferred to the dispatchers and was told that I need to talk to the technician for it."

His experience and genuine caring were unmatched! An employee to make any company very proud. He even offered to meet price of competitors product. In the end it was my engineering analysis of the hardware choices that had me chose the competitor. And that was nothing he could overcome. He gave me every reason to believe Allred was only selling a product they believed in and would fully stand behind for many years to come. I would highly recommend Allred Heating Cooling Electric and Dave Rolig to anyone shopping for these services! Thank you for your prompt and complete support through this experience. Brian Garber"

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."

FAQs for ducts & vents installation and replacement projects in International, WA

Return air vents aren't required in every room, but proper placement is essential for system efficiency. According to industry standards, you'll need one return vent for every 100 to 150 square feet of living space. Ideally, each room would have its own return vent, especially larger rooms exceeding 100 square feet. 

Without adequate return airflow, your HVAC system works harder, energy costs increase, and comfort decreases. A professional assessment can determine the optimal number and placement of return vents for your specific home layout.

Signs that your home needs additional return air vents include rooms that feel consistently stuffy, noticeable temperature variations between rooms, doors that slam shut when the HVAC system operates, or unexpectedly high energy bills. Excessive dust accumulation around supply vents can also indicate inadequate return airflow. 

If you experience these issues, consulting with an HVAC professional can help determine if adding return vents would improve your system's performance.

Supply vents deliver conditioned air into your living spaces, while return air vents draw room air back to your HVAC system for reconditioning. Supply vents push treated air into rooms, while return vents pull air from rooms back toward your heating and cooling equipment. 

Both components are essential for proper air circulation and system balance. Without sufficient return capacity, your HVAC system may experience pressure imbalances that reduce efficiency and comfort.

You should inspect and clean your return air vents at least once annually, according to industry recommendations. However, homes with pets, allergy sufferers, or noticeable dust buildup may benefit from more frequent cleaning. 

Regular maintenance helps maintain good indoor air quality and ensures your HVAC system operates efficiently. Professional duct cleaning, which addresses the entire system beyond just the visible vents, is recommended every few years, depending on your home's specific conditions.
