There are so many options for keeping your home comfortable. Lifetime Heating & Air Conditioning is the "only" HVAC business in Washington that offers a Lifetime Warranty on your equipment while enrolled in our maintenance program. That means, no more diagnostic calls, after hour fees, upselling, or technicians who "always" find something wrong on your equipment. Our heating and cooling technicians carry the highest level of certifications including WA L&I Electrical licenses, NATE certifications, EPA certifications and are licensed, bonded and insured. Employees are background checked, drug tested and comply with safety and driving requirements. We are specialists in furnace, air conditioner, heat pump, indoor air quality, and weatherization service, repair and installation. We can service gas fireplaces, humidifiers, generators, tankless and standard water heaters and more! We guarantee your comfort for a LIFETIME!

"Wow, these people were great! After seeing another company struggle to get two very old fas fireplaces to work, our property manager was directed by another fireplace repair place (who no longer services gas fireplaces) to call Lifetime. They sent Travis McKibben to our home, and he was fast, efficient, and most of all, he got the job done and done well. He really knows what he's doing, and is a really nice guy too. If you have to get service on a gas fireplace (especially an older model), or need HVAC work, I highly recommend this company and this technician."

"Our realtor recommended Para home services when we bought our house, so we tried them out.

On top of a thorough maintenance pass -cleaning dryer vents and refrigerator compressors, they also addressed a random list of things like a loose sink, and faulty bath faucet, a couple of dead outlets and misbehaving light switches but also troublshot our mysterious radiant floor system, got it all working and explained how it was set up.

For over a decade, the professionals at Thermo Direct Inc have worked hard for our friends and neighbors in the Triangle area. Helping homeowners and business owners, our comfort system technicians will make sure that your property’s heating and air conditioning equipment works as reliably and energy efficiently as possible. For projects big and small, we provide honest, cost-effective service. Relax... The Doctor is in the House!

"Thermo Direct installed a HVAC for me donated by Resources for Seniors. A friend of theirs who works at RFS, gave them the bid. I thought that was illegal but it was done. The unit never has worked from the day of installation. They had to jerry-rig it to keep it from shutting off. The receptionist asked if I knew how to work the thermostat? It turned out the unit was shutting off as a safety. The water was backflowing into the unit. To stop this action, it would shut down. They tilted it to stop the backlog. It has never cooled properly and required maintenance often. Deryk Lynn would come sometimes because he was at the time, the only licensed tech and everyone else worked under his license. I was charged for parts that were under warranty (the warranty is good for 10 years) and labor 1 year. My warranty on the parts doesn't expire until 2028. They're expensive, unprofessional and will not honor their word. I could go on but space won't allow."

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 thermostat installation and replacement projects in Lynnwood, WA

It's often worth replacing your old thermostat with a newer model that can enhance your home's comfort and energy efficiency. Upgrading to a programmable or smart thermostat can save you up to $200 per year on energy bills. Plus, smart thermostats offer convenient features like remote control and learning capabilities, making your home more comfortable and easier to manage.

Signs of a bad thermostat include your HVAC system not turning on when it's supposed to or failing to reach the desired temperature. If the thermostat's display is blank or not functioning properly, it could be malfunctioning. Another indicator is the HVAC system running continuously without shutting off or cycling on and off too frequently. You might also notice uneven temperatures throughout your home, with some rooms being too warm or too cold. These issues suggest that the thermostat is failing and may need repair or replacement to ensure your HVAC system operates efficiently.

A thermostat should last between 10 to 20 years, depending on its quality and how well it's maintained. Over time, dust, wiring issues, and general wear can affect its performance. Even if a thermostat is still functioning after 10 years, you might choose to replace it to take advantage of newer energy-saving technologies and smart home integrations. Upgrading to a modern thermostat can improve efficiency, offer more control over your home's climate, and potentially lower energy bills.

The number of thermostats you need depends on your home's size, layout, and heating and cooling zones. In a standard single-zone HVAC system, one thermostat controls the temperature for the entire home. However, larger homes or those with multiple floors might benefit from multiple thermostats linked to a multi-zone HVAC system. This setup can offer better comfort and energy efficiency: It lets you customize the temperature in different areas, so you're only heating or cooling the spaces you're using.

Replacing a thermostat typically takes a professional technician about one to two hours to complete. If you're swapping out an existing thermostat for a similar model with compatible wiring, the process can be done in less than an hour. However, installing a new thermostat that requires additional wiring, such as a smart thermostat, or moving the thermostat to a new location can extend the time to two hours or more. Complex installations may also involve cutting into drywall or integrating with other home systems, which can add to the duration.

There are a few things that can cause your home thermostat to fail. The most simple one is age and cleanliness. Dirt, grease, dust, and other small particles can clog sensors and cause malfunctions in readings. You may also have a failing power supply and loose connections, and the simplest cause is that it isn't installed in the right place in your home so it can't properly sense air temperature. Repairing a thermostat costs around $210.
