Fifteen Years on Tiger Mountain Without AC and Why Rebecca Never Thought She’d Need It
Rebecca had been on Tiger Mountain Rd SE in Issaquah for fifteen years. Her manufactured home sat in the Cascade foothills at the edge of the state forest, a corner of King County where the air used to stay cool enough that air conditioning felt like something people in other climates needed, not something a homeowner in Issaquah 98027 would ever seriously shop for.
She called Product Air on May 6, 2026, through a Google search. The ask was simple: she wanted an AC system installed in her manufactured home. But in the same conversation, she explained the fuller picture. The summers on Tiger Mountain had changed: warmer, longer, and with wildfire smoke rolling through the valley in August and September in a way that made opening windows a tradeoff between cooling down and breathing the air outside. She wanted to stay comfortable without opening a window. For the first time in fifteen years, that mattered enough to call.
“I have been here for 15 years and how the summers have been lately, we need something. Could never imagine I’d be getting air conditioning in Issaquah WA.”
Luis arrived on May 19. What we installed on May 28 gave Rebecca a cool house in August. It also cut her winter electric bill in a way she hadn’t asked for and hadn’t anticipated.
What Luis Found in the Utility Closet
The Intertherm electric furnace in Rebecca’s manufactured home was past its recommended service life. Intertherm, now part of the Nortek family, built electric resistance furnaces specifically for the manufactured housing market for decades, and the units were functional and durable in their time. But electric resistance heating works at a 1:1 ratio: one kilowatt-hour of electricity produces exactly one kilowatt-hour of heat, no more.
On Pacific Northwest utility rates, a manufactured home running electric resistance heat through a Cascade winter builds up real monthly costs and Rebecca had been managing those costs with thermostat setbacks at night for years, accepting that as just how her home worked.
The furnace was still running when Luis visited. It hadn’t failed. But it had outlived the age range its manufacturer recommends, was operating with no cooling capability at all, and was delivering heat at the least efficient conversion ratio available in modern residential HVAC. Luis noted it honestly and included it in the options conversation.
The electrical panel also required attention before the new system could be added. A DANGER label on the panel door indicated it had been previously flagged. The electrical crew evaluated the panel and ran a new dedicated circuit for the heat pump, ensuring the new load had a clean, properly sized supply.
Three Options, One Conversation and a Problem Rebecca Hadn’t Come In to Talk About
Luis presented three options at the May 19 visit. All three were heat pumps, not because that was the only way to add cooling to the house, but because heat pumps address both of the things Rebecca had described in the same system: the summer discomfort and the winter electric bill she had been managing around for fifteen years.
Gold Replacement. Midea Evox G2 2-ton heat pump with matching air handler: $14,931.85 (Chosen)
Platinum Replacement. Trane Resolute heat pump system: $16,773.63
Platinum Plus Replacement. Mitsubishi heat pump system: $20,220.68
Here’s what Luis said to Rebecca, word for word or close to it: “Rebecca, as we were here you explained a few things that are important to you. I appreciate you being open with us, as you would with a brother. I heard you say you want air conditioning. Also, this wasn’t the goal, but you mentioned how this old furnace is giving you a high electricity bill. So these three options handle exactly the air conditioning, plus give you a rebate to offset the new air handler cost, plus these systems will drive down your cost of heating.”
That last part was not what Rebecca had come in expecting to hear. She called about summer. Luis heard summer and winter at the same time, because a heat pump solves one and the other simultaneously and the PSE rebate available for converting from electric resistance heat makes the financial case in a way a straight cooling installation never could.
Rebecca chose the Gold Replacement: the Midea Evox G2 with its matching air handler. At $14,931.85, it was the most accessible of the three tiers, and the variable-speed inverter technology underneath it is the same architecture that defines current heat pump performance at every price point.
Why Heat Pumps in Manufactured Homes Make More Sense Than Most Homeowners Know and Why the $1,500 Rebate Is the Reason to Move Now
Manufactured homes in Western Washington represent one of the largest underserved categories in residential HVAC. Many contractors won’t quote them: the tight utility closet dimensions, the floor duct systems typical in manufactured housing, and the electrical panel characteristics of older units create challenges that some companies find easier to avoid than solve. The result is that homeowners in manufactured home communities along Tiger Mountain Road, along Highway 2, and throughout King and Snohomish Counties often go without cooling and continue running aging electric resistance furnaces not because better options don’t exist, but because no one has come out to tell them what’s actually available.
The Midea Evox G2 with its matching vertical air handler is a legitimate solution for the manufactured home format. At 17.5 inches wide and 45 inches tall, the MAUHE-H24B-2A fits the standard manufactured home utility closet, connects to the existing floor duct system, and operates as a matched communicating system with the MO1BE-H24B-2A outdoor unit. The result is a ducted heat pump installation that functions the same as what any conventional home would have, just engineered for the dimensional and electrical realities of manufactured housing.
The PSE rebate here is the piece of the financial picture that changes the conversation most dramatically. Puget Sound Energy offers $1,500 to homeowners who replace an electric resistance heating system with a qualifying ducted or ductless air-source heat pump. The reason the rebate exists is efficiency: electric resistance converts electricity to heat at 1:1. A modern inverter heat pump at Pacific Northwest winter temperatures of 35°F to 45°F, the range Tiger Mountain sees through most of the heating season, moves 2.5 to 3.5 units of heat for every unit of electricity consumed, by extracting heat from the outdoor air rather than generating it.
PSE has a direct interest in that ratio, because the demand reduction on the grid from a single electric resistance system converting to a heat pump is real, and across thousands of homes it is substantial. Rebecca qualified fully: an Intertherm electric furnace is exactly the system this rebate targets, and the Midea Evox G2 meets PSE’s efficiency requirements. The $1,500 came off the installation cost at the time of purchase.
The wildfire smoke dimension of this case is also worth naming clearly. The communities along the I-90 corridor (Issaquah, North Bend, Snoqualmie) sit in a geographic bowl that traps smoke from Cascade fires in late summer. Air quality index readings in Tiger Mountain during August smoke events regularly exceed levels where the EPA recommends keeping windows closed. A sealed HVAC system with upgraded filtration isn’t a luxury upgrade in this context. It’s the only way to maintain air quality inside the home during the weeks when outdoor air is actively harmful. Opening windows to cool a 75°F house when the AQI outside is 175 trades one discomfort for a health risk. Rebecca understood this directly: it was part of why she called when she did.
What We Installed
The Midea Evox G2 MO1BE-H24B-2A is a 2-ton, 24,000 BTU variable-speed inverter heat pump with a side-discharge configuration: compact in footprint, quiet at partial load, and capable of delivering both cooling and heating across the Pacific Northwest’s full seasonal temperature range. The matching MAUHE-H24B-2A air handler, at 17.5 inches wide by 21 inches deep by 45 inches tall, fits the manufactured home utility closet and communicates directly with the outdoor unit to modulate output in real time.
The inverter compressor in the Evox G2 doesn’t stage on at full capacity and cycle off when the thermostat satisfies. It adjusts its output continuously to match the actual load, running slowly on mild days, scaling up on hot afternoons, and maintaining temperature with less swing and lower average energy draw than any fixed-speed system produces. In a manufactured home that has never had cooling before, the change in summer comfort is immediate. The change in winter operating cost is quieter but equally real.

Installation Timeline
May 6, 2026 — Initial Contact
Rebecca called via Google and described what she was looking for: AC for a manufactured home in Issaquah. The visit was scheduled for two weeks out.
May 19, 2026 — Site Visit and Estimate
Luis walked the home, measured the utility closet dimensions, assessed the existing floor duct system, evaluated the electrical panel, and confirmed the outdoor unit placement. All three options were presented and priced on-site the same day, with the PSE rebate included in the explanation.
Product Air handles all permitting for heat pump installations in King County: permit research, application, submission, monitoring, inspection scheduling, and any required resubmissions. For a manufactured home heat pump installation in Issaquah, the permit covers the mechanical work and the new electrical circuit. Permits were pulled within 24 hours and are included in the fixed project price. No variation from the approved estimate.
May 28, 2026 — Installation (HVAC Technicians + Electricians, 1 Day)
The HVAC crew and electricians arrived together. The HVAC team removed the old Intertherm furnace from the utility closet, installed the Midea MAUHE-H24B-2A air handler in the same space, ran the refrigerant line set to the exterior, and connected the system to the existing floor duct runs. The electrical team added the dedicated circuit from the panel to the exterior disconnect at the outdoor unit location.
The Midea Evox G2 outdoor unit was set on a new concrete pad adjacent to the home, level and properly spaced from the wall to allow unrestricted airflow, with the line set routed cleanly from the pad to the utility closet. The system was commissioned, checked for proper refrigerant charge, and confirmed operational before the crew left. Rebecca had working cooling and heat pump heating by that afternoon.
May 29, 2026 — Permit Inspection and Sign-Off
The inspector reviewed the mechanical installation and the new electrical circuit. Permits were signed off. Project closed.
Price and Rebate Transparency
| Program | Amount |
| PSE Electric Resistance to Heat Pump Replacement Rebate | $1,500 |
| Total Rebates | $1,500 |
Base Price: $15,211.52
Final Cost After Rebates: $13,711.52
Payment: Check
The $1,500 PSE rebate is the rebate available when a Puget Sound Energy customer replaces an electric resistance heating system with a qualifying air-source heat pump. Rebecca’s Intertherm electric furnace qualified on the replacement side. The Midea Evox G2 qualified on the efficiency side. The rebate reduced the out-of-pocket cost from $15,211.52 to $13,711.52 at the time of purchase. No mail-in form, no waiting.
This is one of the more impactful per-project rebates in PSE’s current program, specifically because it targets the homeowners who are paying the highest cost per unit of heat year over year. The payback window on converting from electric resistance to a heat pump, when the rebate is included and the seasonal heating savings are counted, is substantially shorter than the 12-year manufacturer warranty on the equipment.
The Long-Term Picture
The Midea Evox G2 at 2 tons serves Rebecca’s manufactured home at the right capacity for the square footage and the layout. The variable-speed inverter compressor runs at whatever fraction of its total output the house actually needs, slowly and quietly on mild September evenings, more assertively on the handful of hot July afternoons the Issaquah foothills see each summer. The result is more consistent temperature, better humidity control, and lower average energy draw per hour than a fixed-speed system cycling on and off at full capacity would produce.
The winter picture is where the change is most concrete. An Intertherm electric resistance furnace at a Pacific Northwest outdoor temperature of 38°F draws full wattage for every degree of heat it delivers. The Midea Evox G2 at that same outdoor temperature operates at a coefficient of performance between 2.5 and 3.0, delivering two and a half to three times the heat energy per kilowatt-hour consumed, by extracting heat from the outdoor air rather than generating it. On a $150 to $200 monthly winter heating bill, that ratio translates to $50 to $80 in monthly savings without changing thermostat setpoints, without managing which rooms to close off, and without the nighttime setbacks Rebecca had been doing for fifteen years to keep the bill from climbing higher.
Word for word, or close to it, what Rebecca’s household said after the work was done: “They couldn’t believe how much they started saving and that they didn’t have to do a night setback to save on energy and electrical bills.”
That’s the outcome that never appears on a spec sheet. Rebecca called about summer. The system she has now handles her winters differently than anything she’s had since moving to Tiger Mountain: quietly, automatically, without a manual adjustment at bedtime. The 12-year manufacturer warranty and 3-year Product Air labor warranty mean that outcome is protected through the period when any installation issue or component concern would surface.
Key Takeaways
- Manufactured homes in Western Washington qualify for ducted heat pump installation using vertical air handlers specifically sized for the manufactured home utility closet and many homeowners in this category go without cooling because contractors routinely decline the work rather than solving for the format.
- PSE offers a $1,500 rebate when a customer replaces an electric resistance heating system with a qualifying ducted or ductless air-source heat pump; this is one of the most accessible rebates in the PSE program because it doesn’t require gas-to-electric conversion. It requires only that the existing heating was electric resistance.
- The Midea Evox G2 MO1BE-H24B-2A with MAUHE-H24B-2A air handler installed in a manufactured home with existing floor ductwork in Issaquah, WA 98027 cost $13,711.52 after a $1,500 PSE rebate in May 2026.
- A heat pump replaces electric resistance heating at 250–300% efficiency versus the 100% of an electric furnace at typical Pacific Northwest winter temperatures, which produces real monthly savings that accumulate across every heating season for the life of the system.
- The wildfire smoke events that move through the Snoqualmie Valley and the I-90 corridor communities in late summer make a sealed HVAC system with filtration a practical necessity rather than a comfort upgrade, opening windows during a 175 AQI smoke event to cool the house trades one problem for a health risk.
- Product Air handles all permitting for heat pump installations in King County, including for manufactured homes. Permit research, application, inspection scheduling, and corrections are included in the fixed project price with no variation from the approved estimate.
Product Air in the Issaquah Foothills and the Manufactured Home Communities Along Tiger Mountain
Product Air Heating, Cooling and Electric works across the Issaquah foothills: Tiger Mountain, the communities along the Highway 18 corridor, and the manufactured home parks and rural properties that sit outside the standard HVAC contractor service radius. Rebecca’s home isn’t the kind of project that populates a contractor’s lead generation dashboard. It requires someone who will drive out, assess the real constraints of the space, and tell a homeowner what’s possible rather than what’s convenient to install.
Luis has been doing exactly that for more than 20 years. The fact that Rebecca lived without cooling for fifteen years in a community that now regularly sees wildfire smoke in August, not because she didn’t want it, but because no one had ever told her it was an option in her home is the kind of thing that stays with you. We’d rather it didn’t happen to the neighbors still managing their summers on Tiger Mountain with a box fan and an open window.
