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."

"They installed our AC/Heat Pump 9.5 years ago on a 10 year warranty. We had the motor burn up and smoke (even when the technician was out testing) and they refused to replacement because it still worked. They said the problem was a solenoid for the coil. I don't know about you but I don't want an electrical motor continually smoking. And to add insult to injury, they were going to charge me $800 for a 1 hour job to replace the solenoid with a 1 month warranty. Don't trust then to be reasonable and/or responsible!"

"I won't call any other heating or AC experts ever again. Twice now, I've had incomparable experiences. I had another highly reputed company come diagnose my failed furnace and provide an estimate, but AirPros' price for the same part and repair was much more reasonable and furnace repairs are not cheap, so the difference mattered significantly. AirPros also treated me like family. Go with this family business, you will be happy."

"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."

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.
