I specialize in remodeling and home repairs for all aspects of the home. I will always take utmost care to make sure it is done right above industry standards. The customer will always be clearly informed what are the best options and understand the cost involved. I have been in business since 2013 and have many happy customers.

"Tom is wonderful - knowledgeable, reliable, and very professional. He fixed my very old and sad-looking door, and when I wanted to enlist his help for more projects, he pointed out what needed to be repaired and what did not, rather than trying to persuade me into booking more work with him. definitely a trustworthy man and would 10/10 recommend!"

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."

At Arden Heating & Cooling we specialize in the sales, installation, and repair of residential heating and air conditioning systems. Including Gas furnaces, Heat pumps, Ductless units, A/C, and Water Heaters. We are an owner operated business that has over 15 years in the HVAC trade. We take pride in the quality of our work and our ability to stay reasonably priced compared to others. We want to make you as comfortable in your home as possible. Here at Arden Heating & Cooling we offer free estimates and discounts for new systems, existing system upgrades, and maintenance plans. All of our work includes a manufacturers warranty and a 5yr labor warranty on any of the work that we do. Look forward to doing business with you.

"A prompt and thorough response, unlike simply informing me that there was nothing they could do, they actively researched the warranty on my current system (expired and void due to builder installation) before discussing a replacement option. I was then presented with several options, each accompanied by a quote. When asked, they recommended that I opt for a more economical quote that better suited my usage and requirements. I highly recommend this company. They were punctual and worked diligently, even during the peak summer months in the hottest room in my house (the attic). I will certainly recommend them to any of my friends and will utilize their services for any future needs related to air conditioning or furnace repair, as well as routine maintenance."

We are a family owned and operated company doing business in Washington since 1984. We take pride in being able to offer our customers quality service at an affordable price. We strive to ensure each and every customer is 100% satisfied with our work. Give us a call today to see how we can create a “Taylor-Fit” solution for your home!

"Tyler from Taylor heating and AC was the best. It was a hot Saturday (mid 90 degrees) and he crawled up into a 115 degree F attic to help resolve our AC. Not only did he identify the problem, he also fixed the issue for us on the spot so we could have AC during this heatwave—all while working under immensely hot conditions. I’d give a 10 out of 5 stars if I could."

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 thermostat installation and replacement projects in Redmond, WA

Smart thermostats may be worth it for many homeowners. They come with various features, including voice control and smartphone apps. Vacation mode can help lower energy usage when you’re out of town for an extended period. Alert warnings let you know about major spikes or drops in temperature. Smartphone apps can track energy usage, and smart thermostats can learn your routine over time to adjust your temperature and reduce wasted energy consumption automatically.

You typically do not need more than one smart thermostat. While it’s common to see multiple mechanical thermostats throughout a large home, multiple smart thermostats may try to override each other. This can lead to problems with the HVAC system. Ensure the unit you buy has the option for dual- or multi-zoned systems to avoid compatibility issues.

Installing a programmable or smart thermostat may save you $180 per year in utility costs. A big part of this comes from a smart thermostat’s ability to learn and adapt to your regular routines. With smartphone apps or web-based interfaces, you also have the option to control your thermostat when you’re not home.
