In Carnation, the flood map is part of the mechanical drawing. Put a furnace back where the old one was and you can fail an inspection you did not know applied.
Dispatched from our own shop at 387 Butler Ave, Monroe — not from a call center two counties over. That is about 18 miles away.
Carnation sits at 102 feet in the Snoqualmie Valley, between Duvall and Fall City, where the Tolt and Snoqualmie rivers both flood seasonally. That is not trivia here — it is written into the mechanical code.
Chapter 15.64 of the Carnation Municipal Code requires that in a flood hazard area, “mechanical equipment and utilities appurtenant to the residential structure shall be elevated at least one foot above the base flood elevation,” with the lowest floor elevated a foot or more above BFE on new construction, substantial improvement or reconstruction after substantial damage.
In practice that means a furnace, air handler, water heater or heat pump in a flood-hazard property in Carnation cannot simply go back where the old one was. Equipment gets platformed or relocated, the condensate and gas runs change with it, and all floodplain development needs a local permit through the city. A contractor who has not read Chapter 15.64 will quote the job as a straight swap and then discover the difference at inspection.
The city issues its own permits, including a dedicated mechanical permit for AC units, water heaters and furnaces, so this does not go through King County the way an unincorporated address would.
Carnation is in King County and on Puget Sound Energy for both electricity and gas — the same as Duvall, and different from most of our service area, which is on Snohomish County PUD. Worth one specific check: PSE's Duvall heat pump program, worth up to $8,000 for a gas-to-heat-pump conversion, is written for “a Duvall area resident within specific neighborhoods of zip codes 98014 or 98019” — and 98014 is Carnation's ZIP. It is neighborhood-level, not a blanket, and PSE verifies by address. So it is not a promise. It is a phone call worth making before you plan a project, and we are a PSE Trade Ally, which is what their certified-installer requirement means, so we can do the work if your address qualifies.
Marine 4C under the Washington State Energy Code — mild wet winters, a short cooling season, and the conditions cold-climate heat pumps are happiest in.

Real words from neighbors across Monroe and the greater Puget Sound.
"I'm not sure I can even come up with the right words to describe all the ways Genesis has done right by us. They replaced the compressor in our heat pump and were awesome — even put up with my curious kids and explained everything along the way. You won't find a more honest and reliable HVAC company to work with."
"Our furnace just stopped working and we got estimates ranging from $490 up to $909. Genesis came out and fixed it for a fair price. Finally — an honest company!"
"Mike and the team at Genesis were amazing during the storm. As a property manager I've had to request several service calls, and they braved the weather and stayed in constant communication the whole time."
If the property is in a flood hazard area, yes. Chapter 15.64 of the Carnation Municipal Code requires mechanical equipment and utilities to be elevated at least one foot above the base flood elevation, and all floodplain development needs a local permit through the city. That usually means the furnace, air handler or water heater goes on a platform or moves entirely, rather than back into the same spot. It is the single most common thing an out-of-area installer misses here, and it is cheaper to design for than to discover at inspection.
Yes, and we have. We have done refrigeration work at Remlinger Farms, and both the refrigeration and the HVAC at The Carnation Cafe. Walk-in coolers and freezers, reach-ins, prep tables and ice machines, alongside commercial HVAC — which is not something most residential contractors in the valley take on. Both are customers of ours.

Carnation is on Puget Sound Energy, and that decides it. PSE's programs are available through us — we are a Trade Ally, which is what their certified-installer requirement means as of 2 April 2026. Full detail in our 2026 incentives guide.
No. You are about 18 miles from our shop at 387 Butler Ave in Monroe, and we dispatch from there rather than from a call center in another county. Office hours are Monday to Friday, 8:00 AM to 3:30 PM; emergency service is available 24/7 at (425) 261-9095.
