"Quick and efficient. Brad and Rob did a quick and clean install. We had a split AC in place and they got their electrician out quickly and he made the fix in the electrical panel. They sales rep had a bit of a problem with bringing up the financing on his computer, but, it all worked out."

"Tyler from Day and Nite was my service specialist.  Very professional, knowledgeable, and patient.  He took great care with internal components of my aging furnace.  He recommended I replace my furnace due to its age; this and water heater replacement was recommended by my home inspector earlier as well.  He explained the different options for furnace and water heater replacement, their rough estimated cost, and types of retrofitting necessary for newer high efficiency models.  However, the focus remained on ensuring my current furnace was functional.  I appreciated the information without heavy sales pressure.  
I received a discounted rate because I purchased a maintenance plan.  I will be using Day and Nite when I need to install a new furnace, and may try them for plumbing.

"We initially had difficulty getting in contact with Air Pros, which is why they only got a B for responsiveness. Once we established contact, a planner came out and gave us detailed information on the system we wanted. They installed the furnace on time and very professionally. They also upgraded our air filtration system and thermostat. We are very satisfied with the work that Air Pros did. We would definitely use them again if we need the services or equipment they provide."

"Our Heat pump was not providing cold air so I called for a repair person to come out and fix it. Evergreen was able to provide me same day service which was impressive and the tech Alec Smith was very professional and skilled. He had the main issue diagnosed within probably 20 minutes and had a replacement part on hand. My complaint with Evergreen and this is probably common throughout the industry is the markup they put on those replacement parts. I needed a dual run Capacitor for which I was charged approximately $175 dollars. After doing a little research I found that this is a $21 part from Grainger or Amazon. That's one **** of a mark-up. I can tolerate a mark-up because of the convenience but I feel 800% is excessive."

"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."

"G&S Heating is the best of the best! They just replaced our 1995 Lennox furnace that they installed with a 2020 Lennox furnace. The crew was phenomenal in craftsmanship and attitude. Our furnace is in the tight crawl space under our home which is a pain in the @#*! They really worked well together and it was so cool to learn that one of the guy's father had installed our furnace back in 1995 and he is still with G&S! Their entire operation focuses on customer service and satisfaction from the phone contacts to the sales reps to the job planners and finally the installers! I am giving G&S my highest recommendation and will have them install our new Kohler 20KW whole house generator soon. Thank you G&S... Tom H"

"The installation did not go well at all. The installers were here all day and they tracked mud through our garage. They also did a sloppy job of installing the lines on the wall in the laundry room. The system didn't work so they called a technician to come check. The tech, Tobias, complained that we woke him up. He was very grumpy and we could hear him having angry conversations on his cell phone. He determined that the installers installed the air system upside down! The system worked backwards - heat came out through the intake vents and drew air from the heat vents! He complained to us that this had happened before. The installers returned a day or two later and were here all day fixing their mistakes. They joked with us that we should get an awesome service contract. Then the system required fine tuning and another tech (Chris, a very nice guy) was here multiple times tinkering with the system. When we called our sales rep, we were told he doesn't work there anymore. We requested to talk with the business owner, and were promised a phone call, which never came. On top of all that, the heat pump is SO LOUD and I wish our rep had explained to us how noisy it would be. At the end of the day, I sometimes wish I would have spent the additional few thousand dollars and hired Greenwood Heating and Air. Blue Flame had the best quote and the friendliest sales rep. But the installation was a sh!tshow and I cringe every time that heat pump turns on which I can hear from inside my house."

"We requested 3 quotes for this work and SOS Crawlspace was the lowest bid.  The bid was to include removal of rodent infested insulation in the crawl space, to block all potential entry points, install new insulation and build a new crawl space door.  I initially spoke to Daniel who came out the next day to provide a quote.  I subsequently got two additional quotes but SOS was the lowest so we went forward with SOS.  They showed up on time to perform the removal of old insulation.  The infestation was really bad but they cleaned up everything extremely well.  Then they performed the exclusion work to find and block all entry points.  We then waited a few weeks to make sure the rodents were all gone.  They came back and installed the new insulation in a clean and professional manner.  While doing this work they also made sure all the ducting was tightly strung to the joists and not hanging down.  Everything was done promptly, professionally and with excellent quality.  I wouldn't hesitate to hire them again.

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