The One Thing She Asked For Before She Even Mentioned the Furnace
Nicole found Product Air on Thumbtack. She didn’t have an emergency: the 2009 Trane furnace at her 1980 home on 229th Ave NE was still running, still heating the house, still doing its job in the mechanical sense. But she had been living in this house long enough to know the sounds it made, and lately those sounds had changed. The furnace was working harder than it used to. It was struggling in the way equipment struggles when it has been asked to do a job for too long without anyone looking after it.
She could have called any HVAC contractor in Sammamish. She’d dealt with contractors before, for HVAC and for other trades, and none of those experiences had left her feeling confident. The pattern, as she’d experienced it, was contractors who came in, talked fast, quoted fast, and left her with a decision she didn’t fully understand and an outcome she couldn’t verify. She knew her system was aging. What she didn’t have was anyone she trusted to tell her the honest truth about what to do with it.
When she called, word for word or close to it, this is what she said: “I know the system is getting old, but I need someone I could trust and that will be patient with me and will explain everything to me and will answer all my questions.”
Eli showed up on March 19.
How Eli Runs a First Visit With a Skeptical Customer
There is a version of this kind of appointment where the technician walks in, looks at the equipment, comes back with a number, and starts talking about financing options. Eli does not run that version.
The first thing he did at Nicole’s house was listen. He let her say everything: every concern, every frustration, every question she’d been sitting with about her system and about the experience of dealing with contractors in general. He didn’t cut her off to get to the diagnostic. He didn’t steer the conversation toward what he was going to recommend. He listened, and while he listened, he took notes because when he came back with the estimate, every single thing Nicole had told him was going to be in it.
Where she wanted the outdoor unit placed. What she thought about cooling. How she felt about energy efficiency. What the system sounded like. All of it was recorded, and when the estimate came back, Nicole could see it for herself: this was a company that had actually heard what she said.
“During the presentation,” Eli said, “we showed her that we were great listeners and everything was clearly written how she wanted it. Unit on this side of the house. It was recorded. She wanted some cooling. It was on the estimate. Everything she was concerned about was clearly spelled out. Then we educated on the possibilities and how with a mid-tier budget she could get the highest tier of equipment.”
That last part is the thing worth sitting with. With a mid-tier budget, she could get the highest tier of equipment. Here’s how that happens.
What Eli Found in the Mechanical Closet
The 2009 Trane furnace in Nicole’s utility closet is a single-stage, 80% AFUE gas unit, which means for every dollar of gas it burns, it converts 80 cents into usable heat. The other 20 cents goes up the flue. For a furnace installed in 2009, 80% AFUE was a standard mid-efficiency specification; it is not a high-efficiency rating by current standards, which go to 95–98% AFUE for modern 2-stage and modulating units.
Seventeen years of operation without a systematic maintenance program leaves its mark on equipment like this. The blower carries the slow buildup of accumulated debris that reduces airflow over time. The heat exchanger has been through thousands of thermal cycles. The sounds Nicole was describing: the struggling quality, the effort she could hear in the equipment are characteristic of a blower running harder than it should to push air through a system that has quietly become more restrictive with age.
Eli’s read matched what Nicole already suspected: the furnace was operational, but it was in the kind of condition where the question is not whether it will eventually fail. It’s whether it fails on a Thursday afternoon or at 11 PM on the coldest night in February. Beyond that: the house had no air conditioning at all, and no provision for it. Whatever the Sammamish summers brought, this house was handling them without any mechanical cooling.
Two Options, and the Math That Made the Decision Simple
Eli came back with two clearly defined paths.
Silver Replacement: Trane equipment, standard 15 SEER2 single-stage heat pump: $15,895.94
This was the baseline option: a competent, reliable mid-tier system that would give Nicole both heating and air conditioning. Trane is a good brand and the Runtru-class 15 SEER2 units are solid performers. The limitation is that single-stage equipment runs at full capacity or not at all, which means more on-off cycling, less consistent temperature distribution, and less precise humidity control than variable-speed alternatives.
Platinum Plus Replacement: Full Mitsubishi Cold Climate system, 18 SEER2, variable speed, down to -13°F, plus water heater replacement: $16,776.78
The Mitsubishi SUZAK30NLHZ Hyper Heat paired with the SVZAP30NL communicating air handler. Cold climate rated, modulating, variable speed, with an HSPF2 efficiency rating that qualifies for PSE’s Mitsubishi-specific tier bonus. Also included: replacement of the aging water heater.
Nicole chose Platinum Plus. Then the rebates were applied.

The Energy Smart Eastside program, available to homeowners in Sammamish, Bellevue, Issaquah, Kirkland, Redmond, and Mercer Island, but not in Seattle, contributed $6,000 toward a qualifying electric heat pump installation in this ZIP code. Combined with the PSE Mitsubishi rebate for systems rated above HSPF2 8.5, Nicole’s final cost came in below what the Silver option alone would have cost.
The premium system, at the premium specification, for less than the basic one.
What We Installed
The Mitsubishi SUZAK30NLHZ is the Hyper Heat version of the SUZAK series: the same communicating, variable-speed platform used across the top end of Mitsubishi’s residential ducted line, with the cold climate rating that extends full heating capacity down to -13°F. At 2.5 tons and 30,000 BTU, it is correctly sized for a 1,760-square-foot single-story home with the insulation profile typical of a 1980 build in the 98074 ZIP code. The HSPF2 rating exceeds 8.5, triggering PSE’s Mitsubishi-specific rebate tier.
The SVZAP30NL is the communicating electric air handler that replaces the gas furnace as the indoor air distribution component. Unlike the old Trane, which moved air in two states (full blast or nothing) the SVZAP30NL modulates continuously, adjusting airflow to match the actual thermal load of the house at any given moment. On a 55°F March morning in Sammamish, it runs gently. On the first serious cold snap of November, it ramps up. On a hot August afternoon, it delivers the cooling load without the on-off cycling that makes single-stage systems feel either too aggressive or too slow to respond.
The variable-speed operation also produces a meaningful improvement in air quality: longer, quieter circulation runs push more air through the filter media over the course of a day, which matters in a house where the occupant is paying attention to what she breathes, not just what temperature the thermostat reads.
The water heater replacement completed the mechanical picture. Both major systems (climate control and domestic hot water) were addressed in a single project, a single coordination effort, and a single set of permits.

Installation Timeline
Product Air handles all permitting. In the greater Seattle area and Eastside cities, permits for a project of this type run between $149 and $500 depending on project value and permit scope, and are typically pulled within 4 to 24 hours.
March 25, Day 1 — Installation
The Trane furnace came out first. The SVZAP30NL electric air handler went in its place, connected to the existing duct system. Outside, the SUZAK30NLHZ was positioned on the gravel pad, refrigerant lines run through the wall, the electrical disconnect and conduit mounted and dressed against the white siding. The water heater was replaced in the same mechanical space. The system was charged, commissioned, and tested before the crew left.
Day 2 — Inspection
Permits were signed off the following day. No corrections required.
Two days. Two mechanical systems replaced. Both permits cleared.
Price, Rebates, and What Nicole Actually Paid
Base project cost of all equipment, installation, removal of the Trane furnace, water heater replacement, refrigerant, electrical work, permitting, and commissioning: $21,819.83
| Rebate Program | Amount |
| Energy Smart Eastside (Sammamish, 98074) | $6,000 |
| PSE Mitsubishi Rebate HSPF2 Above 8.5 | Applied |
| Total Rebates | $6,400 |
Final cost to Nicole after rebates: $15,419.83
For comparison: the Silver Trane option, with no qualifying rebate at the same tier, was presented at $15,895.94.
Nicole used GreenSky financing at 0% APR for 12 months. Product Air handled the Energy Smart Eastside and PSE applications directly. Nicole did not fill out a form.
A note on geography: The Energy Smart Eastside rebate that contributed $6,000 to this project is specific to Eastside cities: Sammamish, Bellevue, Issaquah, Kirkland, Redmond, and Mercer Island. It is not available on installations in Seattle. If you are in Sammamish, Bellevue, or one of the other qualifying cities and you are replacing an older gas system with an electric heat pump, this program is one of the most significant incentives available anywhere in Western Washington.
The Long-Term Picture
A Mitsubishi SUZAK30NLHZ installed correctly in a 1,760-square-foot single-story home has a realistic service life of 15 to 20 years. The air handler operates on the same timeline. What Nicole is not doing, across any of those winters, is listening for the sound of a furnace that is working too hard, the specific sound she had been living with that finally made her pick up the phone.
The efficiency comparison is concrete. The old Trane was an 80% AFUE single-stage gas furnace. The Mitsubishi Hyper Heat at Sammamish temperatures, where mild winters and shoulder seasons define the majority of the heating load, operates at a coefficient of performance between 2.5 and 4 during the months the thermostat is doing most of its work. That means the home receives multiple units of heat energy for every unit of electrical energy consumed, compared to the 80 cents on the dollar the Trane was delivering from gas combustion. The efficiency difference, across a full heating season, is not marginal.
The air conditioning side is the simpler calculation: the house has never had any. It has it now, in the form of a variable-speed Mitsubishi system sized for the actual square footage, with enough capacity to handle the Sammamish summers that have been arriving more aggressively over the past several years.
The 12-year manufacturer warranty on all Mitsubishi components and the 5-year Product Air labor warranty cover Nicole for the entire window when any well-installed system is most likely to have a question arise. After that, the equipment should simply run quietly, automatically, without requiring her attention.
When Eli’s crew finished and the permits were signed, Nicole said what she said. Word for word, or close to it: “She felt like she was dealing with family. Never expected treatment like this from a contractor.”
That is the bar we hold ourselves to on every job. Not a transaction. A conversation between people who take the outcome personally.
Key Takeaways
- The Energy Smart Eastside rebate, available in Sammamish, Bellevue, Issaquah, Kirkland, Redmond, and Mercer Island, but not in Seattle, contributed $6,000 to Nicole’s project, which made the full Mitsubishi Hyper Heat system cost $475 less than the mid-tier Trane option would have without rebates.
- A 2009 Trane 80% AFUE single-stage gas furnace that sounds like it is struggling is not “probably fine for a few more years.” It is a system where the only question is when it stops, not whether it stops, and where the alternative is a 12-year-warranted Mitsubishi at today’s rebate levels.
- The Mitsubishi SUZAK30NLHZ Hyper Heat maintains full heating capacity down to -13°F, which means it handles everything the Pacific Northwest winter can produce, including the cold snaps that occasionally push into the teens, without the performance drop that limits conventional heat pumps.
- A variable-speed communicating air handler (SVZAP30NL) produces longer, quieter, more consistent circulation runs than single-stage equipment, which improves temperature consistency, reduces cycling, and pushes more air through filtration media over the course of a day, a meaningful difference in a home where air quality matters.
- Product Air applied the Energy Smart Eastside and PSE rebate paperwork directly; Nicole did not fill out a form. GreenSky financing at 0% APR for 12 months covered the balance.
- When a customer tells you she needs someone patient enough to listen, the right response is to actually listen, write down where she wants the unit, what she thinks about cooling, what she’s concerned about, and then hand her an estimate where she can see every one of those things in writing.
The Standard We Hold Ourselves To
Eli has been doing this for more than ten years. He holds his EPA card, his Seattle refrigeration certification, and his Mitsubishi Diamond certification. What none of those credentials capture is the thing Nicole was actually asking for when she called: the willingness to sit across from someone who had been burned before and stay patient until she had every answer she needed.
We cannot make every customer trust us before we arrive. What we can do is earn it while we are there. That means not cutting the conversation short to get to the estimate. It means recording what the customer says and putting it in the proposal. It means explaining the rebate picture fully enough that a person on a mid-range budget can see that the best system is actually available to them, not as a stretch, not as a sales technique, but as a real number they can evaluate for themselves.
Nicole came in looking for someone she could trust. She left with a 12-year-warranted Mitsubishi system, $6,400 in applied rebates, and an experience she described as feeling like family.
That’s the outcome we’re building this company around. One house at a time, on streets like 229th Ave NE, for neighbors who let us in and give us the chance to get it right.
