"I was extremely pleased by the work done by the company and their service techs Kenton and Slavi. I contacted AAA via email late in the evening and received a phone call from them 8:30 the following morning. They juggled their schedule and freed up Kenton to come see me later that same day. Kenton diagnosed the problem as a circuit board failure and, since no replacement was available locally, arranged to have one shipped overnight to AAA. The following morning I received another call from AAA informing me that the replacement part was in. They were able to free up Slavi in the early afternoon to do the install. Slavi arrived on schedule, installed the replacement part, then began running extensive diagnostics to insure that everything now worked properly. He performed a thorough cleaning of the circuitry to remove accumulated dust that can cause circuits to overheat. He measured air temperature and flow rate at multiple vents throughout the house to insure that there were no obstructions in the system. I signed up for one of AAA's low cost annual maintenance plans and was delighted to discover that they had applied the maintenance plan's discount to the work already done. That saved me more than $130. I had a great experience with AAA and am happy to recommend them for your HVAC needs. Their rates are reasonable and their service people are outstanding."

"I've used Seatown for several different service calls. By far the most major one was a partial rewire that replaced some knob and tube wiring. There are several reasons why I view the as an excellent company: - Their administrative and dispatch system is efficiently and competently run. Phone calls during business hours are answered quickly (I've never been on hold for more than a minute or so), they usually have good availability, and the phone operator takes plenty of notes during your phone call which are then communicated to your technician who then has ample context on your problem right up front. - All of the technicians I've worked with have been friendly, communicative, and professional. It always seemed like they know what they're doing. Also, they will patiently explain to you what's causing your issue and what they did to resolve it. - I want to particularly call out Micah, the technician in charge of my rewire project, who was outstanding. He initially came out to diagnose why a couple of circuit breakers were constantly tripping, and identified the need to rewire my garage, office, furnace, and one bedroom. He wrote me an estimate, which I later compared to other companies' and turned out to be quite reasonable. Between my shopping around and heavy holiday demand, it wound up being a few weeks before the rewire was completed. In the intervening time, the circuits tripped a few more times. When I notified Micah of this, he offered to personally come over to further troubleshoot the problem - on Christmas Day - despite Seatown being closed! Micah also found a way to complete the rewire with almost no interior drywall damage. Finally, he was particularly helpful in answering my many questions about my home's electrical system, both before and after the rewire. Micah's combination of professional competence and personal empathy is very uncommon and exemplary. If you hire Seatown for any major electrical work, try to get Micah as your technician. While I am overall very satisfied with Seatown, there are a couple areas that I think could be improved: - At one point between Micah's initial estimate and the start of the rewire project, the circuit connecting my furnace gave out. This was on December 23rd, and I was concerned about my house not having heat. I e-mailed Seatown's emergency mailbox requesting someone come out requesting emergency service, but did not receive a response until December 27th. The office being closed for the holidays is completely understandable, but if you're going to have an emergency mailbox then you should be able to respond to it promptly 24/7, or at least have some kind of auto-reply that sets expectations on when a human can respond. - For relatively minor calls, their service visit fee is quite inelastic relative to the work that is actually done. By which I mean, I've paid about $300 every time they send an electrician out (other than the rewire), regardless of whether they did significant work like replace damaged, bare wire in my breaker panel, or just tell me not to use a space heater. It probably evens out in the long run, but each service call is a bit of a crap shoot on whether I'm going to feel like I got my money's worth. It seems to me to make more sense to charge a lower up-front visit fee, but then charge additionally for specific services rendered."

"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."

"Great. I wanted to replace my oil furnace with a system that does both heating and cooling. They came by, did measurements, and presented some options. I chose the Mitsubishi mini split system because I have a large house and don't need to heat or cool all of it all the time. They installed in a day. Very easy, very boring, I also had them replace the water heater."

"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 five estimates from different installers for a new gas furnace. I knew I would go with John Bassett after the first few minutes of meeting him. This family owned business did an excellent job and at a fair price. No high pressure sales, nor suggestions of additional items like a maintenance contract or vent cleaning. The installation went smoothly, they came on time, cleaned up afterwards and passed the Redmond permitting process with flying colors."

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.
