"All went according to plan. Justin (hope I remember that right) was promptly at my home on Saturday morning. He explained what he was going to do (check the furnace) and verify operation (he found two contactors/relays that were starting to age and recommended replacement soon.) After doing the furnace checkout, he proceeded to get ready to go under the house. We laid out a large covercloth to prevent dirt on the carpet and down he went. All said and done he had the main bedroom vent open (it was jammed by the vent cleaning company) and provided me an option on the air leak. The technician Justin was friendly, explained things completely, was always respectful of my home and me, and was a pleasure to have do the work. He obviously knew his job and completely answered all my questions."

"Mark and his guys helped us install a new AC last summer. They arrived on time and did a great job! So when I was looking for someone to do the maintenance of our furnace, I called them. Todd went above and beyond my expectations. He finished the job and even helped fix my hinge. Both Mark and Todd strike me as very genuine people. And I would definitely hire them again!"

"Our old gas furnace died during the series of snowstorms in February. Stephan came out the day after we called, to give us the bad news that the unit was so old, no replacement parts were available so the whole thing would have to be replaced. Not really surprising given the age of the unit. He also showed me where the water heater (of similar vintage) was corroding around the outlet pipe, so was also in need of replacement. Kris came out within a couple of hours to look over the house and recommended a couple of options. We were leaving town so installation was delayed a couple of days; otherwise we could have had everything done within 48hours of the initial call. The crew that showed up to do the installation (sorry I forgot your names) showed up promptly at 8AM, worked throughout the day, and left our basement cleaner than it started out."

"I purchased a new Navien NPE-240A2 Tankless Water Heater and had it installed. I'm loving the new water heater. It replaces an old Noritz tankless that died just before this installation. The on-site estimate was what sold me. Ken went through all the details and answered a lot of questions from me. Zachary came out with Austin and performed the installation just like I discussed with Ken. Zachary kept me in the loop throughout the installation to ensure I was in agreement with how it was going. Zachary always had my interest at heart and ensured no corners were cut. The installation is much cleaner, and more correct than the previous tankless company did. Zachary even listened to my concern about the astectics of the exterior exhaust and quickly found an easier and cleaner looking way to address my concern. He also removed an old recirculation pump and replaced a new main house shutoff valve. The entire area was treated respectfully and left cleaner than they found it."

"Evergreen installed a new hybrid heat pump system in my house. After researching the options, Evergreen was not only the most reasonable price, but they also scoped out a hybrid system where they would install new duct work and a single air exchanger in the attic and a minisplit in the basement. Scott, the sales person, did not try to upsell me on number of zones (others tried to get me to get 2 units in the basement) and after 2 months with the system, the single unit in the basement is heating the whole basement to our needs. All this was done at a price still considerably lower than the "standard" system price being offered by one of the bigger, similarly named companies. Evergreen was also the only company to propose a hybrid system where they would install a single exchanger in the attic and run new ceiling ducts to the rooms. This was appealing because we don't need to have the cassettes in each room and we didn't need to line the outside of the house with conduit for the cassettes (also the bathroom gets heat, too). Scott was great to work with, answered all my questions, and did his best to size the system correctly. Installation was smooth. There was a small hiccup where the installer accidentally broke a basement window, but Evergreen squared it away. Don and his team were great and the inspections passed. After install support has been great. Denise has been responsive to my questions. Overall, the experience was great with Evergreen and I highly recommend them."

"Cory and Joe were fantastic. The installations went without a hitch. The overall cost was lower than three other quotes I had received for the job. At the beginning of the A/C install I noticed the water heater was leaking, and they were able to replace it the next day. I will definitely use them again."

FAQs for central humidifier installation and replacement projects in Seattle, WA

A crawl space dehumidifier is a worthwhile investment, particularly in humid climates or if you've noticed musty odors, mold growth, or wood deterioration. Though costs range from $3,000 to $9,200, this investment helps prevent structural damage that could require far more expensive repairs later. Beyond structural protection, a properly dehumidified crawl space contributes to better overall indoor air quality and may reduce allergens throughout your home. Consider having a professional assessment to determine if your specific situation warrants this investment.

Addressing crawl space moisture effectively often requires a combination of solutions. A complete approach includes encapsulation plus dehumidifier installation. For minor moisture issues, a basic dehumidifier starting at $1,500 may suffice, while severe problems in larger spaces could require systems costing up to $14,000. The most effective moisture control strategy depends on your specific conditions, making a professional assessment valuable for determining the most cost-effective approach for your situation.

For a crawl space measuring 1,500 square feet, you'll need a dehumidifier with a daily capacity of 30 to 50 pints, with unit costs ranging from $150 to $600. Your local climate and existing moisture levels may necessitate adjusting this capacity—homes in particularly humid regions might benefit from higher-capacity units. Professional installers can measure your specific humidity conditions and recommend equipment that is appropriately sized, balancing initial cost with operating efficiency for your unique situation.

Crawl space dehumidifiers add $300 to $500 to your annual electricity expenses when operating continuously. Energy-efficient models reduce this consumption by roughly 15 to 30% compared to standard units. Most contemporary dehumidifiers feature humidity sensors that automatically cycle operation based on current conditions, helping manage energy usage. Proper crawl space encapsulation significantly improves efficiency by creating a controlled environment that requires less dehumidifier runtime, thereby reducing ongoing electricity costs.
