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."

"We have been living with a 60amp service and Knob and Tube wiring for 37 years. We called Seatown Electric Plumbing Heating and Air,to upgrade our service to200 amps and to replace our Knob and Tube wiring. They promptly sent Matt R, Journeyman Electrician, out to give us an estimate. He was very professional and we walked through the house room by room as he explained what needed to be done to meet code, and asked us what new outlets or features we might want to add in each room. We went from attic to crawl space. Then he sat down with us and walked us through what might have to be done to complete the Job. At which point he ended by giving us a firm estimate of cost and what we would need to do to prepare the house. We made the decision to have them do the work and they put us on the schedule. On the scheduled date Thomas F, and Thomas L arrived along with Matt R. They walked us through the project and told us they had been allotted 5 days to complete the project; on our two story house. They stayed on schedule and actually didn't need a complete day on the fifth day. Thomas F and Thomas L worked tirelessly each day and cleaned up after themselves before leaving each day all this during high 80's temperatures during the day. They took time from their work to answer any and all of our questions as they worked, and at the end of the day showed us what they had completed. All of their work was done with meticulous care given to quality, and journeyman standards to meet and exceed code. I would recommend these two electricians for any electrical project and especially those that may be on the more complicated level. They did our entire house including the installation of a new mast and meter base along with the knew 200 amp breaker box. Thank you Thomas F and Thomas L! Complicating their work was our little granddaughter. She was with us during the whole project and they took extra care to assure her safety and well being. Thomas F even brought her a toy Dinosaur which immediately became her favorite toy. If that were not enough he found out it was my birthday and brought me gift of his personally crafted art work as a present. What a great company and Great People. In this case the aphorism “you get what you pay for” is true. Seatown is worth every dollar."

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 :-("

"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."

For 45 years we’ve been making Puget Sound homes the most healthy, energy efficient and comfortable homes in the country. Our experienced team brings decades of expertise installing and maintaining the most innovative and efficient technology. As a Mitsibushi Cooling and Heating Diamond Contractor, Evergreen Home Heating and Energy has some of the world's most efficient and innovative products available.

"We had Evergreen Home Heating and Energy install a new water heater and furnace, and unfortunately, the quality of their work has been disappointing. Recently, I noticed several issues with the intake and exhaust pipes. Several hanger straps attached to the wall are broken, and one of the joints on the water heater exhaust pipe is leaking water. I suspect this leak is caused by the imbalance due to the broken hanger straps. I expected a professional and reliable installation from Evergreen Home Heating and Energy, but these problems indicate a lack of attention to detail and quality. Based on my experience, I cannot recommend Evergreen Home Heating and Energy. If you’re considering them for your home needs, be cautious and perhaps look elsewhere."

Fairly short notice and our normal HVAC company couldn’t schedule us in time so we called Taylor Heating based on a referral. They had availability and scheduled us well within the needed time.

FAQs for swamp cooler installation and replacement projects in Bellevue, WA

Swamp coolers are quite energy-efficient, using only 15% to 35% of the electricity that traditional central air conditioning units consume. This can lead to significant savings on your energy bills. However, keep in mind that swamp coolers require water to operate and may not cool your home as effectively in extremely hot or humid conditions. When considering overall efficiency, it is essential to weigh both electricity and water usage, as well as the cooling needs specific to your local climate.

Evaporative coolers only work in dry climates because they cool by moistening the air. If the air is already moist, this will have little to no cooling effect. Central AC is a better choice if you live in a humid climate, such as the Midwest, eastern, or western coastal regions.

To install a swamp cooler on a roof, a local HVAC specialist will first find and cut a spot free of wiring and obstructions. They’ll then install metal bracing, legs, brackets, the ceiling duct register, ductwork, power, and thermostat wires. Once installed, they’ll seal all openings, attach duct connections, and install a thermostat. Before leaving, they’ll run cool water piping to the unit and inspect all the connections.

The cost to repair your swamp cooler ranges from $50 to $600, depending on the issue, whether new parts are needed, and the chosen repair service. Depending on the type of pad your system uses, you will need to change out the pads every one to three years for proper operation. When budgeting for the cost to repair a window unit, expect to pay around $230.

The U.S. Department of Energy states that swamp coolers can cool a single room by five to 15 degrees Fahrenheit. However, this largely depends on the size and installation method of the evaporative cooler. You can only achieve these results in a dry climate, such as the American South, as it’s easier to cool rooms in humid environments with central air.

Swamp cooler water usage varies depending on the size of the unit. Smaller evaporative units may use one gallon per hour, while much larger units could use up to 15 gallons of water per hour. Most homeowners can expect their unit to use between seven and 10 gallons of water per hour of usage.
