What should my home’s humidity levels be?

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.

How long does a whole-house dehumidifier last?

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.

Should I run my whole-house dehumidifier in the winter?

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.

What are the energy savings benefits of a whole-house dehumidifier?

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.

Is a portable dehumidifier a viable option for smaller homes?

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.

"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."

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."

He was very knowledgeable about rebate programs, made reasonable recommendations (rather than oversell), was quick with the quote, and got me scheduled within a week. He also offered interest free financing for a year! AirBest was $12K less than my second proposal (because they are a small business and more lean).

"I requested an HVAC service call quote from G&S Heating through Angi, and received a "deal" via Angi for $129. I chose them partly due to that price. G&S Heating ended up billing me $280, and said that was an old outdated deal and would not honor it. Irresponsible and incredibly poor customer relations. Also, the technician they sent did not seem very knowledgeable or experienced. He said the thermostat reading issue I was having would require another service call and the possible replacement of an expensive circuit board. I ended up fixing the problem myself.
