"Everyone I came in contact with was a delight to work with, from Ryan H., to Tyler, to the 2 service installers Dustin & Riley, to their supervisor Ryan & the receptionists! I highly recommend, as the work was done professionally & efficiently by courteous, motivated, happy employees and at the price quoted. This experience was a breath of fresh air after the 12 year nightmare with my old unit (a different company) that they replaced for me. I anticipate lower electric Bill's also, as the new unit operates effortlessly & much quieter compared to the old. I don't mind the price as much for the quality of product and service. Thank you all! Peggy"

"Worked with Greenwood Heating and Air on a furnace replacement and only have excellent things to say about the company and team. Customer service, pricing, timeliness, thoroughness, and friendliness were top notch. Contacted them initially for an inspection of our 28-year old furnace. The technician Frej was prompt, thorough, and courteous, explaining in detail the issues we might face with this still working but old units. Based on the findings we reached out for a quote on a system replacement. Lori took diligent care in listening to our concerns and hopes for a new system, recommending systems that might work for our household. She was always available for follow-up questions, providing answers that really helped us decide on getting a new system (Trane XC80 furnace with air scrubber) via Greenwood H+A. Prices were fair, on par with expectations and quotes from other businesses. On the day of the install, the team at Greenwood H+A, including Jake, Jordan, and Jason were very flexible, coordinating with the roofing company we had hired to take down our chimney and replace with a vent, to get the project moving on time. They were all very communicative, which we appreciated, and gave us regular updates on the progress. They finished what seemed like a big job within the day, despite the install occurring in our cramped crawl space. Our house is now toasty warm again with a great new furnace and all the bells and whistles. Would definitely recommend them for similar job, including for custom requirements as was our case with the roof. Thanks!"

"Rob came out to review our existing system and helped us figure out what kind and brand of heat pump would work best with our system. He was very patient and informative, and answered all our questions without any pressure or up-sells (we had quotes from five providers). We signed the contract and payed our deposit in June 2021, but unfortunately global supply chain issues delayed the parts being received. Day & Nite were communicative of the issue and offered several alternatives, including a refund of the deposit. We opted to wait for the parts. It took four months, but the techs (lead by Jeff B) were fantastic and very accommodating in how we wanted piping and wiring routed. We are very pleased with how it's turned out and loved working with a local (and family owned!) company! Our gas water heater is due for replacement soon, and we'll be coming back to Day & Nite for that!"

"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."

"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!"

"We have been customers of Bassett Heating for many years and always have been so impressed with their service. This is a family owned and operated business and you feel that personal touch. Whenever we have had a furnace issue over the years, John swings by our home quickly to make sure we are not left in the cold. John & his son installed a new furnace for us a few years ago and continued their tradition of great service. We schedule annual maintenance with them for our furnace to keep it in top working condition. When we decided to upgrade and add central air conditioning last year, it was an easy choice to go with Bassett Home Heating. John came by in February 2022, gave us an estimate for both installation timing & price, then returned with the install just in time for the summer heat in 2022. I highly recommend this company!"

"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."

"I had a 4-Zone Heat Pump installed and couldn't be happier with the result. Richard Scott was quick to do an estimate and was very professional, no pressure. Oleg and his team did a very good job with the installation that took a day. The electrician also did a good job, it was done in half a day. The price was fair and competitive compared with the other cotractors who came by. As Richard said, "Enjoy your new HVAC." We are definitely enjoying the benefits. I HIGHLY RECOMMEND Northwest Expert Heating & Cooling !!!"

FAQs for central humidifier installation and replacement projects in Mercer Island, 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.
