"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."

"First started working with Joe getting a quote got 2 bids which the other was cheaper, but decided to get ranger since Mitsubishi is the “top line” he said which I googled and saw it too. We talked that he will put the drainage on the car port and the vent on the side of the house. So when the date of installment came Daniel was on time and he introduce himself. I let him do his job while I was doing my own with my 3yrs and 5 yrs kids. The job was quick so when I check outside I saw that the vent was mounted on my carport. So I called Joe and ask why it was mounted on my carport he said it was in the contract which I didn’t see on the instruction. And so I have to pay if we move it. I was so disappointed! Now I can’t close my carport if I want to get a garage since vent is there. So I have no choice if only Daniel check with me first right from the start what the plan is then there will be no problem! Well the job was done got no choice. Another thing Daniel have to come back two times to fix the drainage since it keeps on leaking my carport. It was finally fixed on the 3rd time when Jared was the tech that fix it. It was so disappointing and I regret that I chose ranger cooking and heating!"

"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."

"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."

"They came out to fix the problem quickly, they were far less than any of the other companies, they sent out somebody that was extremely knowledgeable and he was very personable. I would highly recommend them after looking at no less than eight other companies for the same job. When I have my heat pump replaced, it will be through 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."

"Broker wanted me to get inspection. Was not able to contact the original installer, so my broker recommended Southwest Plumbing. First appointment no show service man got into a job that occupied his whole day. Second appointment missed because service man sick. Finally showed up for third appointment. Congenial and wore mask when he arrived. Said it would be $550 for the inspection. It took fifteen minutes. No parts or anything. Just labor. Easy access. The service person came back upstairs wearing the mask to only cover his mouth, not his nose."

"Everything went well and smooth with their help. I got the proposal with all details at the same day when they came to do the estimate. Our old furnace was built on 1971, and it was in a closet next to the water heater tank. When one other company came to estimate, they wanted to cut a furnace size hole on the wall facing the hallway to fit the machine and we have to find a constructor or handy man to finish, like to build a door or make it look good, but G&S figured out an easy way, which is to turn the machine toward another direction and eventually only cut a vent on the wall. It took two days for all the installation, and they cleaned up when they left and everything looked clean and nice. They also listened to customers. We didn't want the heat pump to be right next to the stairs of our deck, so they chose a spot which was few feet away from the closest spot without any question. We appreciate for that, since the wind blows out from heat pump is kind of strong, and we feel comfortable with where it is at now. One thing I really like is they were on time, and they called around 30 minutes ahead before them showed up. They also take care all the paperwork for the PUD rebate, Costco 10% shop card, and city permits, and all we do is waiting their call to arrange the time."

"It went great! John, the original staff person, evaluated the furnace, explained what was needed and worked with me to select a good replacement. He did not pressure me to purchase a new furnace. A follow-up appointment for a second opinion validated that a new furnace would be best and within a few days (warm weather--not a problem) the furnace was installed with a better option for my electronic filter system. No muss, no fuss, as they say. I am delighted to have this new furnace."

FAQs for central humidifier installation and replacement projects in Sammamish, 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.
